revert-time
Syntax revert-time [revert-time | infinite]
no revert-time
Context config>service>epipe>endpoint
Description This command configures the time to wait before reverting back to the primary spoke SDP defined on
this service endpoint, after having failed over to a backup spoke SDP.
Parameters revert-time — Specify the time, in seconds, to wait before reverting to the primary SDP.
Values 0 — 600
infinite — Causes the endpoint to be non-revertive.
standby-signaling-master
Syntax [no] standby-signaling-master
Context config>service>vll>endpoint
Description When this command is enabled, the pseudowire standby bit (value 0x00000020) will be sent to T-
LDP peer for each spoke-sdp of the endpoint that is selected as a standby.
This command is mutually exclusive with a VLL mate SAP created on a mc-lag/mc-aps or ICB. It is
also mutually exclusive with vc-switching.
Default no standby-signaling-master
service-mtu
Syntax service-mtu octets
no service-mtu
Context config>service>epipe
Description This command configures the service payload (Maximum Transmission Unit – MTU), in bytes, for a
service. The specified MTU value overrides the service-type default MTU. The service-mtu defines
the payload capabilities of the service. It is used by the system to validate the operational states of
SAP and SDP bindings in a service.
On 7210 SAS nodes, when a packet is received on a SAP, the service MTU check includes the length
of the packet and the SAP delineation encapsulation overhead (that is, 4 bytes for a dot1q tag or 8
bytes for a QinQ SAP). Similarly when a packet is received on a SDP Binding (a.k.a. PW) of type vc-
vlan, the service MTU check includes the length of the encapsulated packet along with the vc-vlan
encapsulation length.
If the required payload is larger than the port or channel MTU, the SAP transitions to an inoperative
state.
If the required MTU is equal to or less than the port or channel MTU, the SAP transitions to an
operative state.
