sap
Syntax [no] sap eth-tunnel-tunnel-id[:eth-tunnel-sap-id] [create]
Context config>service>epipe
config>service>ipipe
config>service>vpls
Description This command configures an Ethernet tunnel SAP.
An Ethernet tunnel control SAP has the format eth-tunnel-tunnel-id and is not configured with an
Ethernet tunnel SAP ID. No Ethernet tunnel tags can be configured under a control SAP since the
control SAP uses the control tags configured under the Ethernet tunnel port. This means that at least
one member port and control tag must be configured under the Ethernet tunnel port before this
command is executed. The control SAP is needed for carrying G.8031 and 802.1ag protocol traffic.
This SAP can also carry user data traffic.
An Ethernet tunnel same-fate SAP has the format eth-tunnel-tunnel-id:eth-tunnel-sap-id. Same-fate
SAPs carry only user data traffic. Multiple same-fate SAPs can be configured on one Ethernet tunnel
port and share the fate of that port, provided the SAPs are properly configured with corresponding
tags.
Ethernet tunnel SAPs are supported under VPLS, Epipe and Ipipe services only.
Default no sap
Parameters tunnel-id — Specifies the tunnel ID.
Values 1 — 1024
eth-tunnel-sap-id — Specifies a SAP ID of a same-fate SAP.
Values 0 — 4094
agg-rate-limit
Syntax agg-rate-limit agg-rate [queue-frame-based-accounting]
agg-rate-limit agg-rate [queue-frame-based-accounting] (Epipe services)
no agg-rate-limit
Context config>service>cpipe>sap>egress
config>service>ipipe>sap>egress
config>service>epipe>sap>egress
Description This command defines a maximum total rate for all egress queues on a service SAP or multi-service
site. The agg-rate-limit command is mutually exclusive with the egress scheduler policy. When an
egress scheduler policy is defined, the agg-rate-limit command will fail. If the agg-rate-limit
command is specified, at attempt to bind a scheduler-policy to the SAP or multi-service site will fail.
A multi-service site must have a port scope defined that ensures all queues associated with the site are
on the same port or channel. If the scope is not set to a port, the agg-rate-limit command will fail.
Once an agg-rate-limit has been assigned to a multi-service site, the scope cannot be changed to card
level.
