Hello all,
I've read in the CCNP Switching Exam Cert. Guide that a standby router that

This is strange, since the same virtual MAC address is used by active and
Hi,
Consider this: suppose that you have configured an inband-management
interface
of an IOS-based switch
Switch(config)#interface vlan 1
Switch(config-if)#ip address 172.16.10.2 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
Switch(config)#ip default-gateway 172.16.10.254
Was this NAT or PAT?
If PAT, and the client kept on trying to open up new connections, the source
port would probably be different for each, thus a new xlate in the
translation table.
