QoS Configuration Guidelines | Cisco Systems 7600 specification

Chapter 2 Route Switch Processors and Supervisor Engines

RSP720 with 10GE Uplink Ports

•In 10GE only mode, eight queues are available for QoS. Use the mls qos supervisor 10g-onlycommand to enable 10GE only mode.

The QoS port architecture for 10GE only mode is as follows (Rx/Tx):

–8q8t/1p7q8t (CoS)

–16q8t/1p15q8t (DSCP)

–16q1t/1p15q1t (VLAN)

QoS Configuration Guidelines

As you configure QoS on the RSP720-10GE, consider the following:

•When you switch between mixed-mode QoS and 10GE only mode, any existing QoS configuration on the uplinks is lost. You must reconfigure QoS.

•While transitioning between modes, service will be temporarily lost on the uplinks.

•You can manually shut down all three 1GE ports before issuing the mls qos supervisor 10g-onlycommand to switch to 10GE only mode. If you do not shut down the ports first, the mls qos supervisor 10g-onlycommand shuts down the ports.

•When you switch from 10GE10GE only to mixed-mode QoS, you must issue the no shutdown command on each of the three 1GE ports to resume QoS service on those ports.

•In 10GE only mode, the 1GE ports are visible but they remain in an administratively down state.

Configuring 10GE Only QoS

Cisco IOS Release 12.2SRC introduces a new command to enable QoS features on 10GE uplink ports only. By default, the router runs in mixed mode, which means that QoS is enabled on both the 10GE uplink ports and the 1GE uplink ports.

mls qos supervisor 10g-only

no mls qos supervisor 10g-only

Note You can shut down all three 1GE uplink ports before entering the mls qos supervisor 10g-onlycommand. If you do not shut down the ports first, the mls qos supervisor 10g-onlycommand shuts down the ports.
