Verifying Invert Data on the T1/E1 Interface
Use the show running configuration command to verify that invert data has been set:
Router# show running configuration
interface Serial6/0/0:0
no ip address
encapsulation ppp
logging event link-status
load-interval 30
invert data
no cdp enable
ppp chap hostname group1
ppp multilink
multilink-group 1

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:
Purpose
Command
Writes the new configuration to NVRAM.
