Saving the Configuration
To save your running configuration to nonvolatile random-access memory (NVRAM), use the following
command in privileged EXEC configuration mode:
Purpose
Command
Writes the new configuration to NVRAM.
Router#
copy running-config startup-config
For more information about managing your system image and configuration files, refer to the
Cisco IOS
Configuration Fundamentals Configuration Guide
and the
Cisco IOS Configuration Fundamentals Command
Reference
publications for 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 the 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:
Router#
show interface serial4/0/0
Serial4/0/0 is down, line protocol is down
Hardware is SPA-4XT-SERIAL
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
Reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Restart-Delay is 0 secs
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
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts (0 IP multicast)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 packets output, 0 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
RTS down, CTS down, DTR down, DCD down, DSR down
To find detailed status and statistical information on a per-port basis for the 4-Port Serial Interface SPA, use
the
show controllers serial
command:
Router#
show controllers serial 2/0/0
