vss(config-if)#mac-address 000f.f8aa.9c00

vss(config-if)#^Z

vss-demo-1#

*Jul 12 06:49:56.441: %SYS-5-CONFIG_I: Configured from console by console

vss#sh int ten 2/1/2 | include address

Hardware is C6k 10000Mb 802.3, address is 000f.f8aa.9c00 (bia 000f.f8aa.9c00)

If you issue this command and save the configuration, the Cisco Virtual Switching System will always use the

manually configured address, regardless of the role it assumes.

In addition to the first two methods of specifying the router MAC address, beginning in 12.2(33)SXH2, a method to

select a router MAC address from a VSS reserved pool is available. The router MAC address will be derived from a

formula that uses the domain-id of the VSS pairs. This will make the router MAC unique for a virtual switch domain

and will remain the same irrespective of which becomes active.

VSS(config-vs-domain)# switch virtual domain 100

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

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

Configured Router mac address (0008.e3ff.fd34) is different from operational value

(0013.5f48.fe40). Change will take effect after the configuration is saved and the

entire Virtual Switching System (Active and Standby) is reloaded.

Virtual Switch Link

The Cisco Catalyst 6500 Series Virtual Switching System 1440 consists initially of two Cisco Catalyst 6500 chassis.

In order to bond the two chassis together into a single, logical node, special signaling and control information must be

exchanged between the two chassis in a timely manner. To facilitate this information exchange, you need a special

link to transfer both data and control traffic between the peer chassis. This link is referred to as the virtual switch link

(VSL). (Refer to Figure 4.)

Figure 4. Virtual Switch Header

Because a VSH is appended onto every frame that is sent across the VSL, there are also new port ASIC

requirements to be able to form the VSL. The interfaces that can currently form the VSL are the 10 Gigabit Ethernet

uplink interfaces on the Cisco Catalyst 6500 Series Supervisor Engine 720-10G VSS as well as those on the 8-port

10 Gigabit Ethernet line card (WS-X6708-10G-3C/XL) and the those on the 16-port 10 Gigabit Ethernet line card

(WS-X6716-10G-3C/XL). Note that if the WS-6716-10G-3C/XL line card ports are used to form the VSL, the specific

port must be configured in the “performance mode.”
