480 IP Addressing Commands
Syntax
ip address { ip-address { mask | prefix-length } | dhcp}
no ip address
• ip-address —Specifies a valid IP address.
•
mask —Specifies a valid subnet (network) mask IP address.
•
prefix-length —The number of bits that comprise the IP address prefix.
The prefix length must be preceded by a forward slash (/). (Range: 1-30
bits)
•
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 service
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.
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
