I was looking for a method to filter out the following 802.1X syslog messages from a 6509.
It has 240 ports and every port is configured for 802.1X.
There is a potential that an important error message will be hidden by the large number of 802.1X authentication messages.
%AUTHMGR-5-START: Starting 'dot1x' for client (XXXX.XXXX.XXXX) on Interface GiX/Y
%DOT1X-5-SUCCESS: Authentication successful for client (XXXX.XXXX.XXXX.XXXX) on Interface GiX/Y
%AUTHMGR-7-RESULT: Authentication result 'success' from 'dot1x' for client (XXXX.XXXX.XXXX) on Interface GiX/Y
%AUTHMGR-5-SUCCESS: Authorization succeeded for client (XXXX.XXXX.XXXX) on Interface GiX/Y
%AUTHMGR-SP-5-VLANASSIGN: VLAN XXX assigned to Interface GiX/Y
%AUTHMGR-SPSTBY-5-VLANASSIGN: VLAN XXX assigned to Interface GiX/Y
