i am facing a problem when i add a 2960 switch to the NAC manager switches. I checked the log and i found the following error: cisco SNMP trap event is received from switch [172.22.1.46] which is NOT in our database
Note that i was using the ios: c2960-lanbase-mz.122-44.SE3.bin
then i upgraded the ios to the following:
same problem still exists
Please also note that i configured a 3750 switch (in the same subnet 172.22.1.0) the same way and it was added successfully.
Can anyone help?
