First step towards
configuring the Management IP Interface is to configure a VirtualPortGroup
interface. You can also configure secondary IP addresses on the
VirutalPortGroup interface, similar to a gigabit Ethernet interface IP address
configuration.
To configure the
VirtualPortGroup interface, complete the following procedure:
configure terminal
interface VirtualPortGroup virtual port group number
ip address ip address subnet-mask
ip address ip address subnet-mask secondary
end
Verifying the
VirtualPortGroup Interface Configuration
To verify the
VirtualPortGroup interface configuration, use the
show run interface
VirtualPortGroup command as shown in the example below:
show run interface VirtualPortGroup 0
Building configuration...
Current configuration : 145 bytes
!
interface VirtualPortGroup0
ip address 1.22.3.1 255.255.255.0 secondary
ip address 1.22.2.1 255.255.255.0
no mop enabled
no mop sysid
end
The
VirtualPortGroup interface is in a down state. The interface comes up after the
cable video management interface is configured.
Verifying the
VirtualPortGroup Interface State
To verify the
VirtualPortGroup interface state, use the
show interfaces
VirtualPortGroup command as shown in the example below:
show interfaces VirtualPortGroup 0
VirtualPortGroup0 is up, line protocol is up

Troubleshooting Tips
-
To check if
the management interface IP route is up, use the following command:
show ip interface brief | include VirtualPortGroup 0
VirtualPortGroup0 1.22.2.1 YES NVRAM up up
-
To ping the
VirtualPortGroup interface, use the following command:
ping 1.22.2.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.22.2.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
