Issues while creating Port-Channel : Conflicts with Voice VLAN and Port Security

Hi all,

I am trying to create a LACP port-channel by bundling two ports on two directly connected switches. When configuring the first switch, I was able to bundle the two interfaces under a LACP port-channel. 

However, When I tried bundling the two interfaces on the second switch. I received the errors stating conflicts with Voice VLAN and Port Security.

Switch02#conf t

Can someone please help me with why this is happening?

Hi,

Have you tried defaulting the ports before configuring the etherchannel?

i.e.

default interface range FastEthernet1/0/1 - 2

Thanks

John
