We want to config 2 6506-E Sup720 MSFC3 with redudant supervisors in the event one fails. I have read the documents regarding SSO but still am not sure how to configure. I have configured both sups with the same configuration and trunked via ethernet cable from the supervisor uplink port. When I do a sh redundancy states command i receive the following
my state = 13 -ACTIVE
peer state = 1 -DISABLED
Mode = Simplex
Unit = Primary
Unit ID = 5
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = Non Redundant
Maintenance Mode = Disabled
Communications = Down Reason: Simplex mode
Any help/guidance would be much apprecitaed. Learning as I go working on these LAN switches.
What you are trying to cannot be done with the equipment you currently have. SSO redundancy is for supervisor redundancy within the same chassis. There is VSS that will do what you want as shown in the diagram. Here's a link for that.
