I was checking the arp table on one of my 3750 switch. I found out that in stack 3750 will have a Virutal1 in the 3750 and not sure what is that for? Also all the stack of 3750 had same ip address for this Virtual1
Switch#show ip arp | inc 127.0
Internet 127.0.20.20 - 0000.0000.0000 ARPA Virtual1
Any comments are appreciated!
These IP addresses are used for internal CLI redirection in a stacked environment. While it does not have an impact, but if you do not wish to see this, you might want to upgrade to an IOS which has fix for this
