I'm thinking about some usage of HSRP compare to Stack. Need advice to verify if I'm correct.
I currently have two L3 (non-stackable switch) configure HSRP in SVI for my clustered firewall gateway (each firewall is physically connected to each switch). The switch is connected to each other with a trunk. This setup is to provide physical L3 switch redundancy.
Now, if I have two L3 (stackable switch) and I stack them together, configure SVI as my clustered firewall gateway (each firewall is physically connected to each switch). This setup also provide physical L3 switch redundancy, since any of the switch fails the SVI that is a gateway for clustered firewall is still up.
Thus the above assumption is correct?
Also what is the longest stack cable for 3750 switch? What is the part number?
