i have 6513 switch with FWSM, i was a able to manage FWSM through the ASDM , then after doing some changes (adding log to the access-list)on the ASDM and then apply the changes, it gave an error that it is unable to submit changes . After that, i tried to access asdm and it gave an error: "asdm is unable to read the configuration from the fwsm. Check the configuration on FWSM and then refresh"......
FWSM Firewall Version 3.2(2)
Device Manager Version 5.2(1)F
Any idea to solve this problem.
