I have 4 catalyst6500's running various versions of IOS
Can someone explain what the relevant differences are in the versions.
s72033_rp-IPSERIVCESK9_WAN-n, version 12.2(18)SXF12a
s72033_rp-IPSERIVCESK9_WAN-vm, version 12.2(18)SXF11
I'm guessing from trying to locate information on the Cisco website that SXF12a is the higher version ?
Also what would be the highest version of IOS to put onto our switches ?
