Add PVC-ATM-ARP-Entry

Adds a permanent virtual circuit (PVC) and optionally creates a permanent ARP Entry if the destination protocol address is specified.

If you do not create a permanent ARP entry, the ARP will be periodically aged out and refreshed.

  1. Select an Interface Number

    This parameter specifies the number of the interface over which the router will boot or dump.

  2. Select a Protocol

    Select IP or IPX.

  3. If you select IP, then enter the local client IP address.

    Valid Values: any valid IP address

    Default Value: none

  4. Answer the question specify destination protocol address?

    If you answer yes, the resulting ARP entry will be permanent and you will be required to enter the protocol address.

    Valid Values: any valid IP address

    Default Value: 0.0.0.0

  5. Enter the Destination ATM address.

    This is the ATM address of the remote ATM ARP server. If this entry is also a server, no remote ATM ARP server will be called.

    Valid Values: any valid IP address

    Default Value: none

  6. Enter the Permanent Virtual Circuit VPI to be used for this ARP entry.

    Procedures for connecting the ATM device to a LAN Emulation Configuration Service (LECS) may include use of a reserved Virtual Path Identifier (VPI)/Virtual Channel Identifier (VCI) pair. The VPI is located in the data cell header and are used to route the data cell to its destination.

    The VPI is assigned by the switch when the connection is established.

    Valid Values: any valid value in the range of 0 - 255

    Default Value: 0

  7. Enter the Permanent Virtual Circuit VCI to be used for this ARP entry.

    Procedures for connecting the ATM device to a LAN Emulation Configuration Service (LECS) may include use of a reserved Virtual Path Identifier (VPI)/Virtual Channel Identifier (VCI). The VCI is located in the data cell header and are used to route the data cell to its destination.

    The VCI is assigned by the switch when the connection is established.

    Valid Values: any valid value in the range of 0 - 65535

    Default Value: 0

Select the Submit button.

Change ATM-ARP-Client-Configuration

This option changes the ATM-ARP-client-configuration.

  1. Select an Interface Number

    This parameter specifies the number of the interface over which the router will boot or dump.

  2. Select a Protocol

    Select IP or IPX.

  3. If IP, then enter the local client IP address.

    Valid Values: any valid IP address

    Default Value: none

  4. Select the Submit button.

  5. Enter the changes you want to make to the following parameters:

    1. Answer yes or no to the question, This client is also a server?

      When the client is configured to also be a server, both functions share the same ATM address.

      Both the CIP client and ARP Server age their ARP entries. Once the timer expires, these ARP entries are deleted. The Refresh Timeout value is the length of time that an ARP entry will be kept before aging out.

      If traffic is flowing when an ARP entry gets aged, that traffic will cease for a period until a new ARP entry is created. To avoid an interruption in service, use the automatic refresh option. This option allows the client to transmit either an ARP to the ARP Server or an InATMARP to the target client some time before the ARP entry expires. If the target replies, then the timer of the ARP entry is reset. If the target does not, then the entry is deleted. The ARP Server automatically sends out an InATMARP message before aging an entry in its table.

    2. Enter a Refresh Timeout value.

      Valid Values: an integer number of minutes in the range of 0 - 65535

      Default Value: 5 minutes

    3. Enable auto-refresh

      This parameter specifies whether an ARP Request will be sent to the ARP Server or an InATMARP Request will be sent to the client immediately before an ARP entry is aged out.

      Enabling auto-refresh could cause entries to be retained in the cache regardless of their usage. On networks with a large number of nodes, this can lead to an excessive number of entries in the cache, which might adversely affect device performance. However, on networks with a small number of nodes, this option is useful in reducing broadcast ARP traffic.

      Valid Values: Yes or No

      Default Value: No

    4. Answer yes or no to the question Refresh by InAtmArp?

      If Yes, and if auto-refresh is enabled, then InAtmArp requests will be periodically transmitted to confirm the existence of the remote host. If No, then AtmArp requests will be transmitted to the ARP Server to reconfirm the ARP entry.

    5. Select ESI

      Select the ESI index number from the scrolling list. (the list of configured ESIs that you previously configured using the Add ESI network configuration option).

      Default Value: Burned In

    6. Answer yes or no to the question Use internally assigned selector

      If you answer yes, an automatically generated value will be used as the selector component of the ATM address.

      If you answer no, then you should enter a selector value.

      Valid Values: any single octet value that has not been previously used and is within the range defined for the device.

      Default Value: none

    7. Validate PCR for best effort VCCs

      Valid Values: Yes or No

      When yes, Best-Effort VCCs will be rejected if the signaled forward PCR exceeds the Maximum Reserved Bandwidth or the speed of the adapter.

      If no, Best-Effort PCRs will be rejected without regard to the signaled Peak Cell Rate.

      Enter a Maximum Reserved Bandwidth for incoming VCCs (Kbps)

      This value defines the maximum acceptable Sustained Cell Rate (SCR) for an incoming VCC.

      Valid Values: Specify an integer in the range of 0 to the line speed of the ATM device.

      Default Value: 155000 Kbps

      If SCR is not specified on the incoming call, then this parameter defines the maximum acceptable Peak Cell Rate (PCR). Calls received with traffic parameters specifying higher rates will be released. This parameter is applied to both forward and backward Cell Rate parameters.

      The constraint imposed by this parameter is applicable to best effort connections (if "validate PCR" is yes) and is compared to the PCR on the incoming call.

    8. Use Best Effort Service for Control VCCs

      Specifies the type of traffic characteristics to be associated with Control VCCs.

      Valid Values: Best Effort or Reserved Bandwidth

      Default Value: Best Effort

      Bandwidth is not reserved for best effort traffic.

    9. Peak Cell Rate of outbound control VCCs (Kbps)

      Specifies the Peak Cell Rate (PCR) traffic parameter for the Control VCC. This PCR value is used for both the forward and backward PCR values of both best effort and reserved bandwidth VCCs.

      Valid Values: an integer Kbps in the range of 0 - line speed of the ATM device

      Default Value: If Best Effort VCC, then default is 155000. Otherwise, no default is provided.

    10. Sustained Cell Rate of outbound control VCCs (Kbps)

      Specifies the bandwidth reserved by all VCCs on a given ATM device. (Sustained Cell Rate can be considered to reserved bandwidth.)

      Valid Values: an integer Kbps in the range of 0 - control VCC PCR

      Default Value: none

      This parameter is applicable only when Best Effort Service is not selected for Control VCCs.

    11. Use Best Effort Service for Data VCCs

      Specify Yes or No. This parameter specifies the type of traffic characteristics to be associated with Data VCCs. Bandwidth is not reserved for best effort traffic.

    12. Peak Cell Rate of outbound Data VCCs (Kbps)

      Specifies the Peak Cell Rate (PCR) traffic parameter for the Data VCC. This PCR value is used for both the forward and backward PCR values of both best effort and reserved bandwidth VCCs.

      Valid Values: an integer Kbps in the range of 0 - line speed of the ATM device

      Default Value: If Best Effort VCC, then default is 155000

      Otherwise, no default is provided.

    13. Sustained Cell Rate of outbound Data VCCs (Kbps)

      Specifies the Sustained Cell Rate (SCR) traffic parameter for the Data VCC. (Sustained Cell Rate can be considered to reserved bandwidth.) This parameter is applicable only when Best Effort Service is not selected for Data VCCs.

      Valid Values: an integer Kbps in the range of 0 - PCR value for Data VCC

      Default Value: none

    14. Max Service Data Unit (SDU) size (bytes)

      Specifies the Maximum SDU size that will be specified when calls are placed from this client address. It also is used to verify incoming calls. This parameter cannot be set to a value greater than the Maximum SDU size for the physical ATM interface (port).

      Valid Values: an integer in the range of 72 - Maximum interface SDU

      Default Value: 9188

    15. Click to indicate whether this configuration, if a server, is participating in server synchronziation. Answering yes to this question indicates whether the ARP database for the LIS upon which this server resides will be distributed.

    16. If this is a server, enter a Server group ID.

      Valid Values: 0 - 65535

      Default Value: 1

    17. Click to indicate if this server will Accept sessions from a non-configured Directly Connected Server.

    18. Enter a Hello Interval. This value specifies the time in seconds between sending of Hello messages for the local server.

      Valid Values: 0 - 65535

      Default Value: 3

    19. Enter a Dead Factor. This value specifies the multiple of Hello intervals after which this server should be considered down by DCSs.

      Valid Values: 0 - 65535

      Default Value: 3

    20. Select a Dead Factor. This value specifies the multiple of Hello intervals after which this server should be considered down by DCSs.
