From: thejayman on 27 Apr 2006 13:56 Hi group. I have an issue whilst trying to set up an etherchannel between a 6513 and 6509. As soon as the Channel is up and bonded a switch in an external office (Cat.3650) goes off line and only a reboot of this external switch will bring it back with the Port Channel shutdown. The default gateway of the remote netowrk sits on the 6513, the external switch is just in default setup with ports set to cisco-desktop macro. Port Channel set up below: 6513: .......... ! interface Port-channel1 switchport switchport access vlan 4 switchport trunk encapsulation dot1q switchport mode trunk ! interface GigabitEthernet13/1 switchport switchport access vlan 4 switchport mode trunk channel-group 1 mode desirable non-silent ......... 6509: ........ interface Port-channel1 no ip address switchport switchport access vlan 4 switchport trunk encapsulation dot1q switchport mode trunk ! no ip address switchport switchport access vlan 4 switchport mode trunk channel-group 1 mode desirable non-silent .... Any ideas? Thanks J
From: Merv on 27 Apr 2006 14:38 Is the connection a trunk or not ? If is is then lose the "switchport access vlan 4" command and get rid of DTP - configure the trunk as nonegotiate
From: thejayman on 27 Apr 2006 15:14 Thank for the prompt reply. I am assuming it should be a trunk, I was just trying to allow the channel to pass only traffic on that vlan. So should i enter: no switchport access vlan 4 switchport mode trunk nonegotiate Thanks J

What is the status of the 3560 port that is connected to the network? Is it err-disabled? If so, what is the cause? If you only want vlan 4 on the trunk use switchport trunk allowed vlan otherwise use switch trun native vlan or something like that.
