VSS - Question

[colmgrier]

Does VSS running between dual 6509E switches support ip secondary addressing under SVI's?

interface Vlan1
ip address 134.226.20.3 255.255.255.0
ip standby ip 192.168.20.1
standby ip 192.168.7.1 secondary
standby ip 192.168.7.2 secondary
standby ip 192.168.20.2 secondary
standby ip 192.168.31.1 secondary
standby ip 192.168.31.2 secondary

Regards,

Colm

Hello Colm,

I hope you are well

Why the VSS shouldn't support secondary IP addresses, even if they are not a good practice but just a fix?

see

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1131059

it is not listed on the known limitations

see VSS best practices

Hope to help
