Edge Switches

[rlshelton@archomaha.org]

I have 2 Catalyst 9300 L3 Edge switches. I have 1 fiber connection to the ISP with 1 IP address for Internet traffice and a Metro-E for our WAN fiber connection. I have 2 swithces in case of failure. I have the switches cabled, 1 with the Internet connection and 1 with the Metro-E,  so all I need to do is change out 1 fiber connection. If I have the port shutdown on the backup switch for the Internet connection will it show an IP address duplication error since the IP address to the ISP is the same? The Metro-E port has a different IP address assigned.

Hello,

as long as the port is configured as 'shut' or 'shutdown' there will be no duplicate address problem.

Georg,
I thought that was the case, I just wanted to double check. Thank you.
