Operands

 

pgid0

Sets the Priority Group ID for all packets with CoS 0.

 

 

pgid1

Sets the Priority Group ID for all packets with CoS 1.

 

 

pgid2

Sets the Priority Group ID for all packets with CoS 2.

 

 

pgid3

Sets the Priority Group ID for all packets with CoS 3.

 

 

pgid4

Sets the Priority Group ID for all packets with CoS 4.

 

 

pgid5

Sets the Priority Group ID for all packets with CoS 5.

 

 

pgid6

Sets the Priority Group ID for all packets with CoS 6.

 

 

pgid7

Sets the Priority Group ID for all packets with CoS 7.

Defaults

 

The default CEE Priority mapping table matches the IEEE 802.1Q recommendation for systems

 

 

supporting eight traffic classes. The 802.1Q maps CoS 0 (best effort) to Strict Priority Traffic Class

 

 

1 (PGID 15.6) and CoS 1 to below best effort Traffic Class 0 (PGID 15.7). All other CoS values go

 

 

through unchanged, for example CoS 2 maps to Traffic Class 2 (PGID 15.5), up to CoS 7 and Traffic

 

 

Class 7 (PGID 15.0).

Description

 

Use this command to provision the CEE Priority-to-Priority Group Table. This table maps each of the

 

 

eight ingress CoS into a Priority Group. Use the no priority-tablecommand to return the Priority

 

 

mapping table to the default values.

Usage

 

Only a single CoS can be mapped to a PFC-enabled priority queue. The CoS number must be

Guidelines

 

identical to the priority queue number. If your configuration violates this restriction an error

 

 

message displays and the Priority Group Table is set back to the default values.

 

 

When the CEE map is applied, and the interface is connected to the CNA, only one strict priority

 

 

PGID (PGID 15.0 to PGID 15.7) is allowed.

Examples

 

To define a CEE map of the incoming Priority-to-Priority Groups, use the values in Table 4.
