Verifying the Interface Configuration
Configuring QoS Features on Serial SPAs
The SIPs and SPAs support many QoS features using modular QoS CLI (MQC) configuration. Since
there are no serial SPA-specific QoS features, refer to your network processor documentation for QoS
configuration information.
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 image and configuration files, refer to the Cisco IOS
Configuration Fundamentals Configuration Guide and 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 Clear Channel
T3/E3 SPA.
Verifying Per-Port Interface Status
To find detailed interface information on a per-port basis for the 2-Port and 4-Port Clear Channel T3/E3
SPA, use the show interfaces serial command.
The following example provides sample output for interface port 1 on the SPA located in the first subslot
of the SIP installed in slot 2 of a Cisco ASR 1000 Series Routers:
Router# show interface serial 2/0/1
Serial2/0/1 is up, line protocol is up
