To assign an IP address, use the following commands in INTERFACE mode: 
You can only configure one (1) primary IP address per interface. You can configure up to 255 secondary 
IP addresses on a single interface.
To view all interfaces with an IP address assigned, use the 
show ip interfaces brief command in EXEC mode.
To view IP information on an interface in Layer 3 mode, use the 
show ip interface command in EXEC 
Privilege mode (Figure 13-7).

Management Interfaces
The IOM management interface has both a public IP and private IP address on the internal Fabric D 
interface. The public IP address is exposed to the outside world for Web GUI configurations/WSMAN and 
other proprietary traffic. You can statically configure the public IP address or obtain the IP address 
dynamically using the dynamic host configuration protocol (DHCP). 
Command Syntax Command Mode Purpose
no shutdown
INTERFACE Enable the interface.
ip address ip-address mask [secondary]
INTERFACE Configure a primary IP address and mask on 
the interface. The ip-address must be in 
dotted-decimal format (A.B.C.D) and the 
mask must be decimal and should be 
mentioned in slash format (/xx).
Add the keyword secondary if the IP address 
is the interface’s backup IP address.
Note: When you shut down a management interface, connectivity to the interface's private IP address is 
disabled.
