Likely the CISCO decided to change the way they interpret the tunnel-group-id attribute. There are two ways to pass this attribute (normally, and using a cisco vendor specific attribute.) There are three ways the switch may interpret the string contained therein. 1) numerically 2) vlan name 3) vlan group name
Can anyone suggest anything?
Play with different combinations of the above. Also verify that all the global and interface commands which are applied on a working 12.2 switch remain applied on 15.0. Sometimes command syntax changes and the commands get rejected on upgrade.
