Layer 2 Switching Commands 503
In order to ensure the security of the switches from intruders, it is strongly
recommended that the out-of-band interface be isolated on a physically
separate network from the in-band ports.
Example
The following examples configure the out-of-band interface with an IP
address 131.108.1.27 and subnet mask 255.255.255.0 and the same IP address
with prefix length of 24 bits.
console(config)#interface out-of-band
console(config-if)#ip address 131.108.1.27 255.255.255.0
console(config-if)#ip address 131.108.1.27 /24
ip address-conflict-detect run
Use the ip address-conflict-detect run command in Global Configuration
mode to trigger the switch to run active address conflict detection by sending
gratuitous ARP packets for IPv4 addresses on the switch.
