Configuring Loopback Interfaces
Before configuring Loopback interfaces, make sure the X330WAN module is
inserted in the P330 switch and the power is turned on.
All CLI commands mentioned in this section are described in Chapter 7, "X330WAN
CLI Commands."
To configure Loopback interfaces:
1
Enter the Interface Loopback mode using the
"interface Loopback" [<interface number>[.ip-interface]]
command.
For example, typing
interface loopback 1
configures a loopback with a
Loopback interface number 1.
The prompt changes to
X330WAN-2DS1-N(super-if:Loopbackn)#
where
N
is the switch number and
n
is the loopback interface number.
2 Use the
"ip address" <ip address> <mask>
command to assign an IP
address and subnet mask to the interface.
3 Type
exit
to return to Supervisor mode.
The prompt returns to
X330WAN-2DS1-N(super)#
Note: For the first inteface to be configured the following message appears:
The primary management interface has changed.
For this change to take effect, you need to copy running-
config startup-config and then reset the device.
You need to issue the
"copy running-config startup-config"
and
"reset"
commands.
Note: You cannot delete an interface if there is a primary management IP (PMI
defined on it).
Checking the Loopback/Fast Ethernet/T1/E1/IP Interface Configuration
After configuring the new interface, you can perform the following tests to verify
that the new interface is operating correctly.
•
Use the
"show ip interface"
[<interface-name>|
<IP interface>|<ip-address>]
command to display IP interface
configured serial and Ethernet ports.
• Use the
"show controllers" [<port>]
command to display the status of
the controller for T1/E1 interfaces.
• Use the
"show interfaces"
[<type>] [<identifier>]
command to
display information on all interfaces: Fast Ethernet, Fabric, Serial, Console, and
