I have several Cisco Catalyst 2960G-48TC-L switches that need to be updated to enable LLDP support. When I checked the IOS releases for this switch, these are listed as current:
15.0.1-SE(ED) 26-Jul-2011
12.2.58-SE2(ED) 27-Jul-2011
Is there a document that explains the differences between the 12.x branch and the 15.x branch?
