When we have two L3 switches connected with multiple SVI, when we do show cdp neighbor details which SVI's IP we suppose to see when we run this command?
As far as I am aware the router will chose the IP address of directly connected interface. This can be changed via "cdp source-interface" command.
On Layer 3 switch the behaviour is different. As per the Cisco's official documentation "When Cisco Discovery Protocol is enabled and the Cisco Discovery Protocol source interface has not been configured, then Cisco Discovery Protocol uses the IP address of the first available interface".
I remember that this command "cdp source-interface" is not supported on some of the IOS versions of Cisco 3560 & 3750.
Anyone with the real devices can do the tests and confirm.
