The model of the IBM Blade server 8852 using the cisco blade switch model OS-CIGESM-18TT-EBU.
There are 4 ports gi0/17,18,19,20 are being used for the external network connectivity. Whenever i connected the port to the cisco core switch port confgiured with vlan 1 access port w/o any other spanning tree commends, the following message appeared in the console
blase switch(config)#inter gi0/17
blade switch(config)#switchport mode access
blade switch(config)#switchport access vlan 1
blade switch(config)#no shutdown
% Shutdown not allowed on this interface
I did the write erase then reload cmd
i did erase startup cmd
the 4 ports 17 to 20 of the blade switch gives the same message
Please give the workaround.
