The protocol-group command configures the CIR, and weight of the packets to be sent to the CPU in specific protocol groups.
The undo protocol-group command restores the default settings.
Table 1 lists the default CIR and weight for protocol groups.
protocol-group { whitelist | user-defined-flow | management | route-protocol | multicast | arp | mpls | access-user | link-layer | network-layer | system-message | blacklist | check-failed | fwddata-to-cp } { cir cir-value | weight weight-value } *
undo protocol-group { whitelist | user-defined-flow | management | route-protocol | multicast | arp | mpls | access-user | link-layer | network-layer | system-message | blacklist | check-failed | fwddata-to-cp }

- |
| cir cir-value |
Specifies the committed information rate (CIR). |
The value is an integer ranging from 0 to 51200, in kbit/s. |
| weight weight-value |
Specifies the weight. |
The value is an integer ranging from 1 to 63. |
Usage Scenario
The remaining bandwidth of the total bandwidth deducting the CIR, will be allocated to these protocol groups based on the weight values.
Table1 Default CIR, and weight for protocol groups (4-level scheduling)
