• dhcp—Obtain the out-of-band interface address via DHCPv4.
Default Configuration
The out-of-band interface (service port) obtains an IP address via DHCP by
default.
Command Mode
Interface (Out-of-Band) Configuration mode
User Guidelines
When setting the netmask/prefix length on an IPv4 address, a space is
required between the address and the mask or prefix length. Setting an IP
address on the out-of-band port enables switch management over the out-of-
band port.
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. This command is only valid for
switches equipped with an out-of-band interface.
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.
Syntax
ip address–conflict–detect run
