Troubleshooting the Serial link

If the Serial Port link is unusable, perform the following troubleshooting:
• Verify the correct cable_type and mode configuration settings.
Use the command "show module config serial <slot>/<port>"
• Verify Wan Status LED state with cable connected:
- Green - Cable type and mode are OK.
- Red - Incorrect cable type or mode
- Off - Cable type is undetectable or not compatible
• Verify remote equipment connected and properly configured.
The remote equipment should mirror the Secure Router's configuration.
• Verify port alarm states
Use the command "show module alarm serial <slot>/<port>"
DTR/DSR alarms cause link outages.
• Verify bundle configuration and statistics
Use the command "show interface bundle <bundlename>"
