PA-E3 Serial Port Adapter Installation and Configuration
OL-3502-04
Chapter 4 Configuring the PA-E3
Configuring the Interfaces
Note
If you need to shut down additional interfaces, enter the interface serial command (followed by
the interface address of the interface) for each of the interfaces on your port adapter. Use the no
shutdown command to enable the interface.
Step 4
Write the new configuration to NVRAM as follows:
Router#
copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration has been stored in NVRAM.
Step 5
Verify that new interfaces are now in the correct state (shut down) using the show interfaces command
(followed by the interface type and interface address of the interface) to display the specific interface.
provides examples of the show interfaces serial command for the supported platforms.
Table 4-2
Examples of the show interfaces Command for the Supported Platforms
Platform
Command
Example
Catalyst RSM/VIP2 in Catalyst 5000
family switches
show interfaces serial, followed
by slot/port
(port-adapter-slot-number/
interface-port-number)
The example is for interface 0 on a port
adapter in port adapter slot 1.
Router#
show interfaces serial 1/0
Serial 1/0 is administratively down,
line protocol is down
[Additional display text omitted from
this example]
Catalyst 6000 family FlexWAN module
in Catalyst 6000 family switches
show interfaces serial, followed
by mod_num/bay/port
(module-slot-number/
port-adapter-bay-number/
interface-port-number)
The example is for interface 0 on a port
adapter in port adapter bay 0 of a FlexWAN
module in module slot 3.
Router#
show interfaces serial 3/0/0
Serial 3/0/0 is administratively down,
line protocol is down
[Additional display text omitted from
this example]
Cisco 7120 series routers
show interfaces serial, followed
by slot/port
(port-adapter-slot-number/
interface-port-number)
The example is for interface 0 on a
port adapter in port adapter slot 3.
Router#
show interfaces serial 3/0
Serial 3/0 is administratively down,
line protocol is down
[Additional display text omitted from
this example]
