Usage Guidelines
The VLAN must already exist before you can add or delete ports. Use the
create vlan
command to
create the VLAN.
You must configure a loopback port with a unique loopback VLAN tag ID before adding rate-shaped
ports.
This command is not supported on SONET modules.
Example
The following example sets up bi-directional rate shaping using a loopback port and a rate-shaped port.
First, create the VLAN that will have rate-shaped ports as members:
create vlan ratelimit
Create the loopback port to rate-shape ingress traffic:
configure vlan ratelimit add ports 1 loopback-vid 100
Configure the user port that will be rate-shaped:
configure vlan ratelimit add ports 2 soft-rate-limit
Configure rate-shaping to be at 5% maximum bandwidth for ingress and egress traffic:
configure qosprofile QP1 minbw 0 % maxbw 5 % priority low 1,2
