shaper-policy
Syntax shaper-policy name
no shaper-policy
Context config>port>ethernet>network>egress
Description This command assigns a shaper policy to the specified port.
The shaper policy defines shaper parameters such as shaper group, and PIR and CIR rates.
The shaper policy is defined in the config>qos>shaper-policy context. Refer to the
7705 SAR Quality of Service Guide, “QoS for Hybrid Ports”, for more information.
The no form of this command reverts to the default.
Default “default”
Parameters name — specifies an existing shaper policy name
unshaped-if-cir
Syntax unshaped-if-cir cir-rate
no unshaped-if-cir
Context config>port>ethernet>network>egress
Description This command sets the CIR rate for the aggregate of all the unshaped VLANs (that is,
network interfaces) on the port. The default cir-rate is 0 kb/s. When the cir-rate is set to max,
the CIR rate adopts the maximum rate of the port. The actual rate of the port is dictated by
the physical port speed, which can be overwritten by the egress-rate sub-rate command.
If the cir-rate is higher than the sub-rate, the cir-rate is stored in the configuration database
but the sub-rate limit is used.
Note:
• The port shaper rate applies to the bulk of access and network traffic. Thus, once the
configured egress shaper rate is reached, both the access and network traffic
scheduling pauses.
• For hybrid ports, there can be a single shaper policy on access egress and a single
shaper policy on network egress. Therefore, all the SAP traffic and all the network
traffic is each bound to its own shaper group in the shaper policy (access and network
shaper policy, respectively). In other words, shaped SAPs and the bulk/aggregate of
unshaped SAPs are shaped together as per the shaper policy assigned to the access
egress. A similar behavior applies to network traffic, where the shaped interfaces and
the bulk/aggregate of unshaped interfaces are shaped together as per the shaper
policy assigned to the network egress.
