config>service>vpls>sap
Description This command enables the translation of BPDUs to a given format, meaning that all BPDUs
transmitted on a given SAP or spoke SDP will have a specified format.
The no form of this command reverts to the default setting.
Default no bpdu-translation
Parameters auto — Specifies that appropriate format will be detected automatically, based on type of bpdus
received on such port.
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
no l2pt-termination
Context config>service>vpls>sap
Description This command enables Layer 2 Protocol Tunneling (L2PT) termination on a given SAP. L2PT
termination will be supported only for STP BPDUs.
This feature can be enabled only if STP is disabled in the context of the given VPLS service.
Default no l2pt-termination
disable-aging
Syntax [no] disable-aging
Context config>service>vpls
config>service>vpls>spoke-sdp
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 and/
or spoke SDPs by entering the disable-aging command at the appropriate level.
When the disable-aging command is entered at the VPLS level, the disable-aging state of individual
SAPs or SDPs will be ignored.
