Can any body help me with this
although cisco sw advisor said that the best IOS for my hardware 6509 Sup720 IOS: (s72033_rp-IPSERVICESK9_WAN-M), Version 12.2(18)SXF16 suits the WiSM; And I tested it already with WiSM version 5.0 but when I've upgraded the WiSM to version 6.0 the service interface from the switch side says:
B5_Noc2_CS1(config)#int gig 4/9
% This interface cannot be modified
can anyone solve this issue; as the customer refuse to upgrade the switch IOS & He wants to use the latest ED WiSM sw 6.0; so please Help !!!!!
