Hello all
I am finding a strange config issue in my cisco WS-C6513 switch while i try to create a L2 etherchannel with my production server.The IOS version is (c6sup2_rp-JK2O3SV-M), Version 12.1(27b)E4 .
the config coomands i tried for the ether channel is as follows .I can see that the Po30 is auto matically negotiated to dot1q trunk, which i didnt really configured.
Router#sh ether sum | in Po30
30 Po30(SU) - Gi11/36(P) Gi11/37(P)
Router#sh run int gi11/36
Building configuration...
Current configuration : 128 bytes
!
interface GigabitEthernet11/36
switchport
switchport access vlan 139
switchport mode access
channel-group 30 mode on
end
Router#sh run int gi11/37
Building configuration...
Current configuration : 128 bytes
!
interface GigabitEthernet11/37
switchport
switchport access vlan 139
switchport mode access
channel-group 30 mode on
end
Router#sh run int po30
Building configuration...
Current configuration : 173 bytes
!
interface Port-channel30
description PortChannel-30 to DSSACS1
switchport
switchport access vlan 139
switchport trunk encapsulation dot1q
switchport mode access
end
My doubt is , is this normal ? or is this an issue? I dont need the dot1q encapsulaion that is coming automatically.Kindly advice.
Kind regards

Since switchport mode access is configured, the switchport trunk commands are ignored. You can safely remove that configuration by doing a 'no switchport trunk encapsulation dot1q'

I am unable to remove it using that command.
