I am port-channeling between 2 6500 switch with Sup720's running IOS with the following code: s72033-jk9sv-mz.122-18.SXD7
The original configuration, is listed below.
Int port-channel 1
No ip address
Logging event link-status
Logging event bundle-status
Logging event trunk-status
Switchport encapsulation dot1q
Switchport native vlan 2
I wanted to remove a VLAN from the trunk using the following command.
switchport trunk allow vlan remove 206
when I typed in the command, the port-channel, the went down, and remained down until I typed in the command on the second switch.
Po1 went down, on the first switch,
Po1A came up on the first switch
Po1 went down on the second switch, Po1B came up on the second switch.
Is there something I can do to prevent this from happening in the future?
