Enter the Maximum frame age.

Valid Values: An integer number of seconds in the range of 1 to 4

Default Value: 1

This parameter maps to the S5 parameter in the ATM Forum LAN Emulation Over ATM Specification.

Select the Submit button.


Set Frame Size

Select the Maximum frame size.

Valid Values: 1516, 4544, 9234, 18190.

Default Value: 4544

This parameter maps to the S3 parameter in the ATM Forum LAN Emulation Over ATM Specification.

Select the Submit button.


Set IP Broadcast Cache Age

Enter the IP cache age.

Valid Values: An integer number of minutes in the range of 2 to 20

Default Value: 5

Select the Submit button.

Set Partition Address Resolution Request Forwarding Domain

This option partitions the control distribute VCCs.

Proxy clients are placed on one Control Distribute VCC and all other clients are placed on another Control Distribute VCC. Partitioning the VCCs reduces nuisance traffic at many clients because non-proxy LECs do not receive proxy LEC traffic, and vice-versa. However, each frame must now be forwarded on two VCCs. In general, partitioning the VCCs is recommended.

The Set Partition Address option partitions the control distribute VCC into a "proxy control distribute" VCC and a "non-proxy control distribute" VCC.

Indicate if you want to partition by clicking the radio button.

Select the Submit button.


Set Partition Unicast Frame Domain

This option partitions the multicast forward VCCs.

Proxy clients are placed on one Multicast Forward VCC and all other clients are placed on another Multicast Forward VCC. Partitioning the VCCs reduces nuisance traffic at many clients because non-proxy LECs do not receive proxy LEC traffic, and vice-versa. However, each frame must now be forwarded on two VCCs. In general, partitioning the VCCs is recommended.

The Set Partition Unicast option partitions the multicast forward VCC into a "proxy multicast forward" and a "non-proxy multicast forward" VCC.

Indicate if you want to partition by clicking the radio button.

Select the Submit button.


Set Security (LECS Validation of Joins)

This option enables LECS validation of joins.

Multiple Emulated LANs can exist on a single ATM network and stations that are not on the ELAN can be physically connected to stations that are on the ELAN. This presents a security risk because unauthorized stations can connect to the LES and attempt to use its services.

The LECS is a security component. The LES will not allow clients to join the ELAN without receiving approval from the LECS when join validation is enabled.

If enabled, the LES-BUS communicates with the LECS across the LES-LECS Security Interface in order to validate each LE Client's request to join the ELAN.

The LES-LECS Security Interface for this ATM Interface must be enabled

  1. Select an ESI to be used as the ESI component of the local ATM address used when calling the LECS.

  2. Select the Submit button.

  3. Enter a LECS Interface selector to be used for this interface.

    Valid Values: Any unassigned selector value selected from the range of reserved selector values.

    Default Value: 1, if not already in use by another LAN Emulation component using the same ESI you have assigned to this component.

Select the Submit button.

This option sets trace filter mask for an ATM address.

For each VCC, if the ATM address of the entity at the other end of the VCC matches the ATM-address-value on all bits set by the ATM-address-mask, then packet tracing can be performed on that VCC.

For packet tracing to occur, enable it in the ELS subsystem.

Enter the ATM address trace filter mask.

Valid Values: any 20 bytes in hexadecimal (not an actual ATM address)

Default Value: FF:FF:FF:FF:FF:FF:FF:FF:FF:FF

Select the Submit button.


Set ATM Address Trace Filter Value

This option sets trace filter value for an ATM address.

You can specify that a LEC address serve as a filter for unwanted trace packets. Enter a 20-byte hexadecimal string. This value is compared with the bit string result of logically ANDing the ATM address trace filter mask that you specify and the primary ATM address of LECs. If the resulting bit string and the ATM address filter value match and if packet tracing is enabled, the packet is traced. The filter applies to incoming and outgoing packets.

For packet tracing to occur, enable it in the ELS subsystem.

Enter the ATM address trace value.

Valid Values: any 20 bytes in hexadecimal (not an actual ATM address)

Default Value: 00:00:00:00:00:00:00:00:00:00.

Select the Submit button.

Set Traffic Control sets traffic characteristics of the "control distribute" VCC.

You can tune an operational network by adjusting the defaults for traffic parameters, it is best to allow bandwidth allocation for VCCs to default to Best Effort.

Default Value: 0

Select the Submit button.


Set Traffic Type Multicast Forward VCC

Set Traffic Multicast sets traffic characteristics of the multicast forward VCC.

You can tune an operational network by adjusting the defaults for traffic parameters, it is best to allow bandwidth allocation for VCCs to default to Best Effort. Best Effort may sometimes lead to excessive retransmissions; however, overriding Best Effort for VCCs may result in interoperability problems, causing network traffic to stop.

  1. Select the Traffic type.

  2. Select the Submit button.

  3. Enter the Peak cell rate.

    Valid Values: an integer Kbps in the range of 1 to 155 000

    Default Value: 155 000

Select the Submit button.


Set Traffic Type Validate Peak Cell Rate

Set Traffic Validate determines whether the LES-BUS is to validate the peak cell rate specifed on incoming control direct or multicast send VCCs. When you specify this command, the LES-BUS rejects all control direct or multicast send VCCs that specify a peak cell rate that is greater than the speed of the ATM interface.

Indicate if you want to validate the peak cell rate by clicking the radio button.

Select the Submit button.


Rename LES-BUS

Use the Rename option to change the name of a LES-BUS.

Select the Submit button.


Security Add

Use the Security Add option to enable the LECS to authenticate clients before they establish communication with the LES-BUS. This will allow the LES to validate join requests with the LECS enabled for the LES-BUS ATM device.

When join validation is enabled, the LES will not allow clients to join the ELAN without receiving validation from the LECS. Note that validation of clients that connect to the BUS is not under configuration control. The BUS always validates connecting clients with the LES.

Indicate that you want to enable join validation by clicking the radio button.

Select the Submit button.


Security Set Address

Use the Set Address option to configure the address for the security interface between the LECS and the LES.

  1. Select the ESI to be used for this address.

  2. Select the Submit button.

  3. Enter the LECS interface selector to be used for this address.

    Valid Values: any hex value in the range of X'00' - X'FF' that has not been already assigned .

    Default Value: 01

Select the Submit button.


Security Set Traffic Configuration

Use the Set Traffic Configuration option to configure the traffic type for the security interface between the LECS and the LES. The LES-LECS security interface is the LE Services component responsible for multiplexing configuration requests from the LESs on the MSS Server to the LECS (which may or may not be on the MSS Server).

Select the traffic type from the list of choices.

Select the Submit button.


Token Ring LAN Emulation RIF Timer

This parameter sets the aging timer for the RIF cache.
