Debugging Policy Configuration Errors
You can debug a policy configuration failure caused by processing on the VSM.
Step 1 Enter the debug aclmgr all command if the policy references an ACL.
Step 2 Enter the debug ipqos all command.
Step 3 Enter the policy map and class commands to collect logs for all operations.
Step 4 Save the Telnet SSH session buffer to a file.
If you are debugging a policy on a port profile, it might be easier to first install it directly on an interface.
You can debug a policy configuration failure on the VEM.
Step 1 Enter the module vem module-number execute vemdpalog clear command.
Step 2 Enter the module vem module-number execute vemdpalog sfqosagent all command.
Step 3 Enter module vem module-number execute vemdpalog start command.
Step 4 Enter the policy-map command which will execute the command once again with the DPA debug traces
output to vemdpalog.
Step 5 Enter module vem module-number execute vemdpalog stop command.
