To configure a shaped VLAN with aggregate rate limits, use the agg-rate-limit
command in the config>router>if>egress context. If the VLAN shaper is not
enabled, then the agg-rate-limit settings do not apply. The default aggregate rate
limit (PIR) is set to the port egress rate.
Unshaped VLANs use default rate limits (PIR is the maximum possible port rate and
CIR is 0 kb/s) and use 16-priority scheduling mode. All unshaped VLANs are
classified, queued, buffered, and scheduled into an aggregate flow that gets
prepared for third-tier arbitration by a single VLAN aggregate shaper.
In order for the aggregated unshaped VLANs to compete fairly for bandwidth with the
shaped VLANs, a single, aggregate CIR for all the unshaped VLANs can be
configured using the unshaped-if-cir command. The aggregate CIR is applied to all
the unshaped VLANs as a group, not to individual VLANs, and is configured in the
config>port>ethernet> network>egress context.
