Troubleshooting Using Debug Systrace
Telnet Authentication and De-authentication
Do not change the aaaDebugFunction flag under Dshell, keep it the default setting.
In addition with that use below commands to capture maximum debug information:
-> debug systrace no appid all
-> debug systrace appid 20 level debug3
-> debug systrace watch enable
After gathering all information disable the systrace using below command.
-> debug systrace watch disable
The best way to troubleshoot is to verify the working and non-working case. Compare the results of both
cases and find the possible point of failure.
Get the IP Address from Default VLAN
