Need your input on the following:
I have an existing 4510 with dual sup configuration (active/standby) sso mode. We will be adding another 4510 as a redundant chassis. I am planning on implementing HSRP, and configure it both switches as Active/Standby setup.
My question is regarding the existing switch with the dual SUP's. Should I leave it as such? Make it the active switch. I don't think I need to configure HSRP on the standby SUP, right?
I guess what I am hoping to happen is, if the active SUP fails, the standby SUP takes over on the same switch. If the whole switch fails, the secondary switch takes over.
Is that how it would work? Any other solutions to consider with what I will have in terms of hardware?
