MAC ADDRESS TYPE ON VSS

[David Martinez Garcia]

Hi all.

I have a doubt with the type on the SVI mac address in a VSS enviorenment.

I need to know if the mac-address type  of the SVI is virtual or phisical.

This is because in case of a total failure of a node, i need to know if the mac will change.

Thank you!

Hello David,

When the VSS is started for the first time, the  initial VSS active supervisor engine assigns a router MAC address for  the VSS. By default, the supervisor engine assigns a MAC address from  its own chassis. After a switchover to the second chassis, the VSS  continues to use the MAC address from the previously VSS active chassis  as the router MAC address.
