Verifying the Interface Configuration

DSU mode 0, bandwidth 44210 Kbit, scramble 1, VC 0

Saving the Configuration

To save your running configuration to nonvolatile random-access memory (NVRAM), use the following
command in privileged EXEC configuration mode:
Command
Router# copy running-config startup-config
For information about managing your system images and configuration files, refer to the Cisco IOS
Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals
Command Reference publications that corresponds to your Cisco IOS software release.
Verifying the Interface Configuration
Besides using the show running-configuration command to display your Cisco ASR 1000 Series
Routers configuration settings, you can use the show interfaces serial and the show controllers serial
commands to get detailed information on a per-port basis for your 2-Port and 4-Port Channelized T3
SPA.

Verifying Per-Port Interface Status

To find detailed interface information on a per-port basis for the 2-Port and 4-Port Channelized T3 SPA,
use the show interfaces serial command.
The following example provides sample output for the serial interface on an unchannelized T3:
Router# show interfaces serial3/0/0
Serial3/0/0 is down, line protocol is down
Hardware is SPA-2XCT3/DS0
MTU 4470 bytes, BW 44210 Kbit, DLY 200 usec,
Encapsulation HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
