hello dear

before i have problem, i installed CWLMS3.2 and ACS 4.2 and everything is ok, but after upgrade, ACS 4.2 to ACS 5.2, CWLMS can't authenticate to devices and get their configuration. i checked everything include creadential, and i debuged aaa authentication and tacacs on devices. it seems devices can not get username from CWLMS.

also i run putty on CWLMS server and try to telnet to devices with ACS username nad password, and the result, there is no problem, and i can telnet to device with ACS username and password without any problem.

the below text is the output of debug on devices when CWLMS try to archive configuration:

Hi dear Gaganjeet Chugh <>

Thanks for your reply, i think, I have another story, I didn’t integrate CWLMS with ACS and CWLMS does not know anything about TACACS and ACS Server and just wants to telnet into devices.

Please give me more explanation if I made mistake.

Thank you
