Configuring the PA-2CE1 Interfaces
Step 6
Reenable interfaces by doing the following:
a.
Repeat Step 3 to reenable an interface. Substitute the no shutdown command for the shutdown
command.
b.
Repeat Step 4 to write the new configuration to memory.
Use the copy running-config startup-config command.
c.
Repeat Step 5 to verify that the interfaces are in the correct state. Use the
show interfaces command followed by the interface type and interface address of the interface.
For complete descriptions of software configuration commands, refer to the publications listed in the
“Related Documentation” section on page vi.
Performing a Basic Configuration
This section contains guidelines for performing a basic channelized E1 configuration and a basic
channelized E1 ISDN PRI configuration: enabling a controller and specifying IP routing. You might also
need to enter other configuration subcommands, depending on the requirements for your system
configuration and the protocols you plan to route on the interface. This section contains the following
subsections:

Example
Cisco 7200 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 1.
Router# show interfaces serial 1/0
srp 1/0 is administratively down, line
protocol is down
[Additional display text omitted from this
example]
VIP2 in Cisco 7000 series and
Cisco 7500 series routers
show interfaces serial, followed
by slot/port adapter/port
(interface-processor-slot-number/
port-adapter-slot-number/
interface-port-number)
The example is for interface 0 on a port adapter in
port adapter slot 0 of a VIP in interface processor
slot 1.
Router# show interfaces serial 1/0/0
atm 1/0/0 is administratively down, line
protocol is down
