Description: Periods of sustained mixed traffic (UDP multicast, IP, and TCP) might cause the MWR 
1941-DC router to crash.

To collect data for reporting router issues, issue the following command:

show tech-support—Displays general information about the router when it reports a problem.

To collect data for redundancy-related issues, issue the following commands while in EXEC mode:

show cdp neighbors—Displays detailed information about neighboring devices discovered using 
Cisco Discovery Protocol (CDP).

show controllers—Displays information that is specific to the hardware.

show ip interface—Displays the usability status of interfaces configured for IP.

show redundancy—Displays current or historical status and related information on redundant Dial 
Shelf Controllers (DSCs).

show standby—Displays Hot Standby Router Protocol (HSRP) information.

show standby brief—Displays Hot Standby Router Protocol (HSRP) information; specifically, with 
the brief keyword specified, a single line of output summarizing each standby group.

To collect data for ROMmon issues, issue the following command while in EXEC mode:

showmon— Displays currently selected ROM monitor.

If a router reboot to ROMmon occurs, issue the dir device ID command where device ID is slot0:, and 
look for the router processor or network processor exception file (crashinfo* or pxf_crashinfo* 
respectively). Once you have located one of these files, you can email the file along with a description 
of the problem to your Cisco representative.

 

The following sections describe updates to the published documentation for the Cisco MWR 1941-DC
