pvst — Specifies the BPDU-format as PVST. Note that the correct VLAN tag is included in the
payload (depending on encapsulation value of outgoing SAP).
stp — Specifies the BPDU-format as STP.
l2pt-termination
Syntax l2pt-termination [cdp] [dtp] [pagp] [stp] [udld] [vtp]
no l2pt-termination
Context config>service>vpls>sap
config>service>vpls>spoke-sdp
Description This command enables Layer 2 Protocol Tunneling (L2PT) termination on a given SAP. L2PT
termination is supported for STP/CDP/DTP/PAGP/UDLD and VTP PDUs.
NOTE: CDP, DTP, PAGP, UDID and VTP is supported only on 7210 SAS-R6. It is not supported on
7210 SAS-X.
This feature can be enabled only if STP is disabled in the context of the given VPLS service.
Default no l2pt-termination
Parameters cdp — Specifies the Cisco discovery protocol.
dtp — Specifies the dynamic trunking protocol.
pagp — Specifies the port aggregation protocol.
stp — Specifies all spanning tree protocols: stp, rstp, mstp, pvst (default).
udld — Specifies unidirectional link detection.
vtp — Specifies the VLAN trunking protocol.
disable-aging
Syntax [no] disable-aging
Context config>service>vpls
config>service>vpls>sap
config>template>vpls-template
config>service>pw-template
Description This command disables MAC address aging across a VPLS service or on a VPLS service SAP.
Like in a Layer 2 switch, learned MACs can be aged out if no packets are sourced from the MAC
address for a period of time (the aging time). In each VPLS service instance, there are independent
aging timers for local learned MAC and remote learned MAC entries in the VPLS forwarding
database (FDB). The disable-aging command turns off aging for local and remote learned MAC
addresses.
When no disable-aging is specified for a VPLS, it is possible to disable aging for specifc SAPs by
entering the disable-aging command at the appropriate level.
