Step 7: Configure the system virtual MAC address.

By default, the VSS system uses the default chassis-based MAC-address pool assigned to the switch that is

resolved to be the active switch when the switches initialize. As a result of events such as stateful switchover,

the MAC may change. Set a virtual MAC address for the VSS system so that either active supervisor will use the

same MAC address pool, regardless of which supervisor is active, even across a system reload.

C6500-VSS(config)# switch virtual domain 101

C6500-VSS(config-vs-domain)# mac-address use-virtual

Configured Router mac address is different from operational value. Change will

take effect after the configuration is saved and the entire Virtual Switching

System (Active and Standby) is reloaded.

Step 8: Save the running configuration, and then reload the entire system (both chassis).

copy running-config startup-config

reload

When the switches initialize after this final reload, the VSS configuration for dual Supervisor Engines is complete.

Step 9: If you are configuring a VSS quad-supervisor system, fully insert the additional Supervisor Engines in

each chassis, to complete the VS4O configuration.

Because the Supervisor Engines have been prepared to boot the same version of code that is already active

on the VSS, they boot and communicate with the In-Chassis Active (ICA) Supervisor Engine and receive the

appropriate VSS variable configuration. A one-time reload initiates on the inserted Supervisor Engines, and the

modules boot as full participants in the VS4O platform.

After the Supervisor Engines have fully booted, you can observe the VS4O status.

The command output shows which switch and slots contain Supervisor Engines in ACTIVE, STANDBY HOT, and

STANDBY HOT (CHASSIS) modes.

Step 10: Configure QoS.

On the Cisco Catalyst 6500 Supervisor Engine 2T based switches, QoS is enabled by default and policies

for interface queuing are defined by attached service policies. The QoS policies are now defined using Cisco

Common Classification Policy Language (C3PL), which is similar to Modular QoS CLI, in order to reduce

operational complexity.

All interface connections in the distribution and core are set to trust differentiated services code point (DSCP)

markings. Even though this design is configured to trust DSCP markings, it is a best practice to ensure proper

mapping of CoS to DSCP for VoIP. This mapping is accomplished by overriding the default mapping of CoS 5

“voice bearer traffic” to DSCP 40, with DSCP 46, which is the EF per-hop behavior for voice.

This egress QoS policy is configured to accommodate the 10-Gigabit and 40-Gigabit Ethernet cards which use a

1P7Q4T queuing architecture.
