MCF Reinit

Use the Reinit option to reinitialize the entire MAC Filtering system to a previous configuration without affecting the rest of the router.

To reinitialize MAC filtering, select the yes radio button and then select the Submit button.


MCF Set-Cache

Use the Set-cache option to change the default cache size.

To set the new cache size:

  1. Enter the filter number to which this cache size applies.

    Valid values: 1 to 255. The upper limit may be lower depending on the amount of memory available on the device.

    Default value: 1

  2. Enter the new cache size.

    Valid values: 4 to 32768

    Default value: 16

Select the Submit button.


MCF Update Add Source

Use the Update Add Source option to add or change source MAC information in a specific filter-list. This option specifically lets you add a hexadecimal number to compare against the source MAC address.

The order in which the filter-items are added to a given filter-list is important as it determines the order in which the filter-items are applied to a packet.

Each use of the Add option creates a filter-item within the filter-list. The first filter-item created is assigned filter-item-number 1, the next one is assigned number 2, etc.

The first match that occurs stops the application of filter-items, and the filter-list evaluates to either Include, Exclude or Tag, depending on the designated action of the filter-list. If none of the filter-items of a filter-list produce a match, then the default action (Include, Exclude or Tag) of the filter is returned.

To add a source MAC information to a filter list:

  1. Enter the filter list name

    Valid values: Up to 16 characters

    Default value: None


  2. Enter a MAC address

    Valid values: 12 hexadecimal characters with no separators

    Default value: None


  3. Enter a MAC mask. This mask is logically ANDed with the designated MAC address in the packet.

    Valid values: 12 hexadecimal characters with no separator

    Default value: X'FFFFFFFFFFFF'


Select the Submit button.


MCF Update Add Destination

Use the Update Add Destination option to add or change information in a specific filter-list. This option specifically lets you add a hexadecimal number to compare against the destination MAC address.

The order in which the filter-items are added to a given filter-list is important as it determines the order in which the filter-items are applied to a packet.

Each use of the Add option creates a filter-item within the filter-list. The first filter-item created is assigned filter-item-number 1, the next one is assigned number 2, etc.

The first match that occurs stops the application of filter-items, and the filter-list evaluates to either Include, Exclude or Tag, depending on the designated action of the filter-list. If none of the filter-items of a filter-list produce a match, then the default action (Include, Exclude or Tag) of the filter is returned.

To add a destination MAC information to a filter list:

  1. Enter the filter list name

    Valid values: Up to 16 characters

    Default value: None


  2. Enter a MAC address

    Valid values: 12 hexadecimal characters with no separators

    Default value: None

    Valid values: 12 hexadecimal characters with no separator

    Default value: X'FFFFFFFFFFFF'


Select the Submit button.


MCF Update Delete

Use the Update Delete option to delete information from a specific filter-list. You delete filter items by specifying the filter-item-number assigned to the item when it was added.

When the Delete option is used, any gap created in the number sequence is filled in. For example, if filter-items 1, 2, 3, and 4 exist and filter-item 3 is deleted, then filter-item 4 will be renumbered to 3.

The order in which the filter-items are specified for a given filter-list is important as it determines the order in which the filter-items are applied to a packet.

To delete a filter item:

  1. Enter the filter list name

    Valid values: Up to 16 characters

    Default value: None

  2. Enter the filter number in the Item Number field.

Select the Submit button.


Patch

Use the Patch option for modifying the router's global configuration. Patch variables are recorded in nonvolatile configuration memory and take effect immediately; you do not have to wait for the next reload of the MSS Server. This command should be used only for handling uncommon configurations. Anything that you commonly configure should still be handled by using the specific configuration commands.

To apply a patch:

  1. Enter the variable to patch.

    ethernet-security
    When set to a non-zero value, zeros the padding that is applied to Ethernet packets whose data portion is less than the physical minimum of 60 bytes. This may be required for security reasons.

    Default value: 0

    rip-static-suppress
    When set to a non-zero value, static routes will not be advertised by RIP over a given interface unless the IP Enable Send Static option is given for the interface. This changes the semantics of the Enable Send Static option. When rip-static-suppress is equal to 0, the list of the routes advertised via RIP is the union of those specified by the interface's RIP flags.

    Default value: 0

    ping-size
    The size of the data portion (that is, excluding IP and ICMP headers) of the ICMP ping packet that is sent via the IP Ping option.

    Default value: 56 bytes

    ping-ttl
    The TTL (time-to-live) sent in pings by the IP Ping option.

    Default value: 60

    ip-default-ttl
    The TTL used in packets that are originated by the router.

    Default value: 60

    more-lines
    The number of lines to display on the console when listing the IP routing table, which uses a "more pipe" (a split vertical bar).

    bgp-subnets new value
    If you want the BGP speaker to advertise subnet routes to its neighbors, set new value to 1.

    Default value: 0

    dls-lnm-supp
    When set to 1, allows you to configure the 0xF4 SAP within DLSw. DLSw can then set up a circuit to carry the LLC-2 flows between LAN Network Manager (LNM) and the LNM support in a bridge product.

    Default value: 0

    Note: You must specify the complete name of the patch variable that you want to change. You cannot use an abbreviated syntax for the patch name.

  2. Enter the new value for the patch.

Select the Submit button.


Set Contact Person

Use the Set Contact-Person option to set the SNMP variable sysContact. This is the name or identification of the contact person for this SNMP-managed node. There is a limit of 79 characters for the sysContact name length.

This variable is for information purposes only and has no effect on router operation.

Valid values: A string of 1 to 79 ASCII characters (new-line characters and blanks may not be included; an empty string is not valid.)

Default value: None

To set the contact person, enter the name in the field and then select the Submit button.


Set Down-Notify

Use the Set Down-Notify option to specify the number of seconds before declaring an interface as being down. The normal maintenance packet interval is 3 seconds, and it takes four maintenance failures to declare the interface as down.

The Set Down-Notify option is used primarily when tunneling LLC traffic over an IP network using OSPF. If an interface goes down, OSPF cannot detect it fast enough because of the length of time that it takes for an interface to be declared down. Therefore, LLC sessions would begin to timeout. You can set the down-notify timer to a lower value, allowing OSPF to sense that an interface is down quicker. This enables an alternate route to be chosen more quickly, which will prevent the LLC sessions from timing out.

Note: If the Set Down-Notify option is executed on one end of a serial link, the same command must be performed at the other end of the link or the link may not come up and stay up.

To set down notify:

  1. Enter the interface number.

    Valid values: 0 to 7

    Default value: 0

  2. Enter the down notification time.

    This is the maximum time that will elapse before a down interface is marked as down. Large values will cause the router to ignore transient connection problems, and smaller values will cause the router to react more quickly.

    Valid values: 1 to 300 seconds

    Default value: 0 which sets interface to the default period of 3 seconds.


Select the Submit button.

The List Devices option will show the down notification time setting for any interface that has the default value overridden.


Set Global Buffers

Use the Set Global-Buffers option to set the maximum number of global packet buffers, which are the packet buffers used for locally originated packets. The default is to autoconfigure for the maximum number of buffers. To restore the default, set the value to 0. To display the setting for global-buffers, use the List Configuration option.

For maximum number of global buffers:

Valid values: 0 to 1000

Default value: 0

To set the global buffers, enter the maximum number of buffers and then select the Submit button.


Set Hostname

Use the Set option to configure various system-wide parameters. The Set Hostname option adds or changes the MSS Server name. The MSS Server name is for identification only; it does not affect any router addresses. The name must be:

To set the hostname, enter the name and then select the Submit button.


Set Inactivity Timer

Use the Set Inactivity-Timer option changes the setting of the Inactivity Timer. The Inactivity Timer logs out a user if the remote or physical console is inactive for the period of time (in seconds) specified. This option only affects consoles that require login.

For inactivity timer:

Valid values: 1 to 65535

Default value: 0

Specifying 0 turns off the inactivity timer. In this case, the router does not log off the console regardless of the amount of time the console is idle.

To set the inactivity timer, enter the time (in minutes) and then select the Submit button.


Set Input Low-Water

Use the Set Input-Low-Water option to configure the value of the low number of receive buffers, or packets, on a per-interface basis, thus overriding the default values.

The memory allocation strategy changes to conserve buffers when the number of free buffers is equal or less than the low or low-water mark value. When a packet is received, and the current value of the interface is less than the low water value, then that packet is eligible for flow control (dropping).

Interface number is the number of the interface that you are configuring. Low number of receive buffers is the low water value.

Lowering the value will make it less likely that packets from this interface will be dropped when sent on congested networks. However, lowering the value may negatively affect performance if it drops packets to the extent that the receive queue is frequently empty. Raising the value has the opposite effect.

Select the Queue or Buffer option of the Operator Console selection to show the low setting.

To set input-low-water:

  1. Enter the interface number.

    Valid values: 0 to 75

    Default value: 0

  2. Select the Submit button.
  3. Enter the number of buffers.

    Valid values: 1 to 255

    Default value: 0 - restores the autoconfigured default which depends on the platform and device.

Select the Submit button.

You will receive a confirmation panel.


Set Location

Use the Set Location (sysLocation) to sets the physical location of an SNMP node. There is a limit of 80 alphanumeric characters for the sysLocation name length. This variable is for information purposes only and has no effect on router operation. It is useful for SNMP management identification of the system.

For location:

Valid values: Up to 80 alphanumeric characters

Default value: None

To set the location, enter the node location to identify this node to SNMP and then select the Submit button.


Set Packet Size

Use the Set Packet Size option to establish or change the maximum size of a packet buffer in bytes.

Attention:   Use this command only under direct instructions from your service representative. Never use it to reduce packet size - only to increase it.

For packet size:

Valid values: 0 to 65535

Default value: 0

To set the maximum packet size, enter the number of bytes and then select the Submit button.


ATM Set QOS for LE Client

This option allows you to set Quality of Service parameters for the LE Client.

  1. Enter the Max Reserved Bandwidth Acceptable for a VCC.

    This parameter applies to both Data Direct VCC calls received by the LEC and Data Direct VCC calls placed by the LEC. For incoming calls, this parameter defines the maximum acceptable SCR for a Data Direct VCC. If SCR is not specified on the incoming call, then this parameter defines the maximum acceptable PCR for a Data Direct VCC with reserved bandwidth.

    This parameter is applied to both forward and backward directions. Calls received with traffic parameters specifying higher rates will be released. If SCR is specified on the incoming call, the call will not be rejected due to the PCR or Maximum Burst Size. The constraint imposed by this parameter is not applicable to BEST_EFFORT connections. For outgoing calls, this parameter sets an upper bound on the amount of reserved bandwidth that may be requested for a Data Direct VCC. Therefore the traffic-type and sustained-cell-rate parameters are dependent upon this parameter.

    Valid Values: 0 to 155000

    Default Value: 0

  2. Select the VCC type.

    If QoS parameters are not negotiated, then this parameter specifies the type of calls placed by the LEC. If QoS parameters are negotiated, this parameter specifies the desired type of traffic characteristics for Data Direct VCCs. When QoS parameters are negotiated, if either the source or target LEC desires a reserved bandwidth connection and both LECs support reserved bandwidth connections (i.e., max-reserved-bandwidth > 0), then an attempt will be made to establish a reserved bandwidth Data Direct VCC between the two LECs. Otherwise, the Data Direct VCC will be a best-effort connection.

    Valid Values: Best Effort or Reserved

    Default Value: Best Effort

  3. Enter the VCC peak rate in Kbps.

    This parameter is the desired peak cell rate for Data Direct VCCs. If QoS parameters are not negotiated, then this parameter specifies the PCR traffic parameter for Data Direct VCC calls placed by the LEC. Otherwise, if QoS parameters are negotiated, this parameter specifies the desired PCR traffic parameter for Data Direct VCCs. The minimum of the desired PCRs of the two LECs is used for negotiated best-effort VCCs.

    When a reserved bandwidth VCC is negotiated and only one of the LECs requests a reserved bandwidth connection, then the desired PCR of that LEC is used for the Data Direct VCC subject to the upper bound imposed by the line rate of the local ATM device. If both LECs request a reserved bandwidth connection, then the maximum of the desired PCRs of the LECs is used for the Data Direct VCC subject to the upper bound imposed the line rate of the local ATM device.

    Valid Values: 0 - 155000

    Default Value: 155000

  4. Enter the VCC sustained rate in Kbps.

    This parameter is the desired sustained cell rate for Data Direct VCCs. If QoS parameters are not negotiated, then this parameter specifies the SCR traffic parameter for Data Direct VCC calls placed by the LEC. Otherwise, if QoS parameters are negotiated, this parameter specifies the desired SCR traffic parameter for Data Direct VCCs.

    When a reserved bandwidth VCC is negotiated and only one of the LECs requests a reserved bandwidth connection, then the desired SCR of that LEC is used for the Data Direct VCC (subject to the upper bound imposed by the max-reserved-bandwidth parameter of the other LEC). If both LECs request a reserved bandwidth connection, then the maximum of the desired SCRs of the LECs is used for the Data Direct VCC (subject to the upper bound imposed by the max-reserved-bandwidth parameters of both LECs). In any case (negotiation or not), if the SCR that is to be signalled equals the PCR that is to be signalled, then the call is signalled with PCR only.

    Valid Values: 0 - 155000

    Default Value: none

  5. Enter the QoS Class for VCCs.

    This parameter sets the desired QoS class for reserved bandwidth calls. If QoS parameters are not negotiated, then this parameter specifies the QoS Class to be used for reserved bandwidth Data Direct VCC calls placed by the LEC. Otherwise, if QoS parameters are negotiated, this parameter specifies the QoS Class that is desired for Data Direct VCCs. Unspecified QoS Class is always used on best-effort calls. Specified QoS Classes define objective values for ATM performance Specified QoS Classes define objective values for ATM performance parameters such as cell loss ratio and cell transfer delay.

    The UNI Specification states that:

    LECs must be able to accept calls with any of the above QoS Classes. When QoS parameters are negotiated, the configured QoS Classes of the two LECs are compared, and the QoS Class with the more stringent requirements is used.

    Valid Values: 0 - 4

    Default Value: 0

  6. Enter the Max Burst Size in frames.

    This parameter sets the desired maximum burst size for Data Direct VCCs. If QoS parameters are not negotiated, then this parameter specifies the Maximum Burst Size traffic parameter for Data Direct VCC calls placed by the LEC. Otherwise, if QoS parameters are negotiated, this parameter specifies the desired Maximum Burst Size traffic parameter for Data Direct VCCs.

    When a reserved bandwidth VCC is negotiated and only one of the LECs requests a reserved bandwidth connection, then the desired Maximum Burst Size of that LEC is used for the Data Direct VCC. If both LECs request a reserved bandwidth connection, then the maximum of the desired Maximum Burst Sizes of the LECs is used for the Data Direct VCC.

    In any case (negotiation or not), the Maximum Burst Size is signalled only when SCR is signalled. Although this parameter is expressed in units of cells, it is configured as an integer multiple of the Maximum Data Frame Size (specified in LEC's C3 parameter) with a lower bound of 1.

    Valid Values: an integer number of frames greater than 0

    Default Value: 1 frame

  7. Click to Validate Peak Cell Rate of Best Effort VCCs.

    If you enable this parameter, Best-Effort VCCs will be rejected if the signalled forward PCR exceeds the line rate of the LE client ATM device.

    If you disable this parameter, Best-Effort VCCs will be accepted without regard to the signalled forward PCR.

  8. Click to Enable Cell Rate Negotiation for Data Direct VCCs.

    This parameter should be enabled only when connecting to an IBM MSS LES.

    If you enable this parameter, QoS parameter negotiation for Data Direct VCCs is enabled and the LE Client will include an IBM Traffic Parameter TLV in LE_JOIN_REQUEST and LE_ARP_RESPONSE frames sent to the LES. This TLV will include the values of Max Reserved Bandwidth, Traffic type, Peak Cell Rate, Sustained Cell Rate, Max Burst Size and QOS Class. These values will be compared to the corresponding local values to determine the negotiated set of parameters acceptable to both parties before signalling for the Data Direct VCC.

  9. Click to Accept QoS Configuration Parameters from LECS.

    If this parameter is enabled, the LE Client should use the QOS parameters obtained from the LE Clients in the LE_CONFIGURE_RESPONSE frames. That is, the QOS parameters from the LE Clients override the locally QOS parameters.


ATM Set QOS for ATM Interface

This option allows you to set Quality of Service parameters for the ATM interface.

  1. Enter the Max Reserved Bandwidth Acceptable for a VCC.

    This parameter applies to both Data Direct VCC calls received by the LEC and Data Direct VCC calls placed by the LEC. For incoming calls, this parameter defines the maximum acceptable SCR for a Data Direct VCC. If SCR is not specified on the incoming call, then this parameter defines the maximum acceptable PCR for a Data Direct VCC with reserved bandwidth.

    This parameter is applied to both forward and backward directions. Calls received with traffic parameters specifying higher rates will be released. If SCR is specified on the incoming call, the call will not be rejected due to the PCR or Maximum Burst Size. The constraint imposed by this parameter is not applicable to BEST_EFFORT connections. For outgoing calls, this parameter sets an upper bound on the amount of reserved bandwidth that may be requested for a Data Direct VCC. Therefore the traffic-type and sustained-cell-rate parameters are dependent upon this parameter.

    Valid Values: 0 to 155000

    Default Value: 0

  2. Select the VCC type.

    If QoS parameters are not negotiated, then this parameter specifies the type of calls placed by the LEC.

Otherwise, if QoS parameters are negotiated, this parameter specifies the desired PCR traffic parameter for Data Direct VCCs. The minimum of the desired PCRs of the two LECs is used for negotiated best-effort VCCs.

    When a reserved bandwidth VCC is negotiated and only one of the LECs requests a reserved bandwidth connection, then the desired PCR of that LEC is used for the Data Direct VCC subject to the upper bound imposed by the line rate of the local ATM device. If both LECs request a reserved bandwidth connection, then the maximum of the desired PCRs of the LECs is used for the Data Direct VCC subject to the upper bound imposed the line rate of the local ATM device.

    Valid Values: 0 - 155000

    Default Value: 155000

  4. Enter the VCC sustained rate in Kbps.

    This parameter is the desired sustained cell rate for Data Direct VCCs. If QoS parameters are not negotiated, then this parameter specifies the SCR traffic parameter for Data Direct VCC calls placed by the LEC. Otherwise, if QoS parameters are negotiated, this parameter specifies the desired SCR traffic parameter for Data Direct VCCs.

    When a reserved bandwidth VCC is negotiated and only one of the LECs requests a reserved bandwidth connection, then the desired SCR of that LEC is used for the Data Direct VCC (subject to the upper bound imposed by the max-reserved-bandwidth parameter of the other LEC). If both LECs request a reserved bandwidth connection, then the maximum of the desired SCRs of the LECs is used for the Data Direct VCC (subject to the upper bound imposed by the max-reserved-bandwidth parameters of both LECs). In any case (negotiation or not), if the SCR that is to be signalled equals the PCR that is to be signalled, then the call is signalled with PCR only.

    Valid Values: 0 - 155000

    Default Value: none

  5. Enter the QoS Class for VCCs.

    This parameter sets the desired QoS class for reserved bandwidth calls. If QoS parameters are not negotiated, then this parameter specifies the QoS Class to be used for reserved bandwidth Data Direct VCC calls placed by the LEC.

    Valid Values: 0 - 4

    Default Value: 0

  6. Enter the Max Burst Size in frames.

    This parameter sets the desired maximum burst size for Data Direct VCCs. If QoS parameters are not negotiated, then this parameter specifies the Maximum Burst Size traffic parameter for Data Direct VCC calls placed by the LEC.
