Thanks for the reply Gert.
On the 4500X, the sequence is (As you describe): Create portchan, then add portchan to physical/member Int. For VSS on the 4500X, it is: SW1(config)#int port-channel 5 SW1(config-if)#switchport SW1(config-if)#switch virtual link 1 SW1(config-if)#no shut SW1(config-if)#exit SW1(config)#int TenGigabitEthernet1/16 SW1(config-if)#switchport mode trunk SW1(config-if)#channel-group 5 mode on The 4500X then "automagically" adds the following to the physical Int (And also restricts what commands you can enter on the member Interface) switchport nonegotiate no lldp transmit no lldp receive no cdp enable service-policy output VSL-Queuing-Policy > Date: Tue, 12 Mar 2013 09:39:58 +0100 > From: [email protected] > To: [email protected] > CC: [email protected]; [email protected]; > [email protected] > Subject: Re: [c-nsp] 4500-X VSS %EC-5-CANNOT_BUNDLE2 > > Hi, > > On Tue, Mar 12, 2013 at 12:42:46PM +1100, CiscoNSP List wrote: > > Portchan conf (That fails): (Hotmail will probably screw the formatting): > > > > interface Port-channel5 > > switchport > > switchport mode trunk > > switchport nonegotiate > > switch virtual link 1 > > > > And Int conf: > > > > interface TenGigabitEthernet1/16 switchport mode trunk > > switchport nonegotiate > > no lldp transmit > > no lldp receive > > no cdp enable > > channel-group 5 mode on > > service-policy output VSL-Queuing-Policy > > Don't configure stuff on member interfaces after joining a channel.
