The following commands effect all ports on an ASIC, when you configure one of these commands on a port, all ports connected to that ASIC will have the same command applied. For example on the WS-X6724-SFP card, two ASIC’s are present with one ASIC dedicated to ports 1-12 and the second ASIC dedicated to ports 13-24. So using this example if one of the commands below is configured on port 7, ports 1-12 will be configured with the same command and parameters. All commands shown below are interface commands.
Configures the size of each queue (Queue Depth)
wrr-queue bandwidth (except Gigabit Ethernet LAN ports)
Configures the time/BW used by WRR Scheduling to service each queue (not PQ)
Configures the tail drop threshold, used when WRED not configured
Enables WRED on a queue, which disables tail drop. use the no form of this command to return to tail drop.
wrr-queue random-detect min-threshold
wrr-queue random-detect max-threshold
Enables the minimum and maximum percentages per queue per threshold, where CoS values are assigned to a queue and threshold number using ‘wrr-queue cos-map’
Maps the CoS value of a packet to a standard queue. The CoS is derived from the Internal DSCP value using the DSCP-COS map.
Maps the CoS value of a packet to the PQ. The CoS is derived from the Internal DSCP value using the DSCP-COS map.
