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.
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.
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

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.
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.
