VLAN Trunking refers to the ability for a port to cary mulitple traffic from multiple VLANs. What you wish to do is create a port-channel and group the ports together.  This gets confusing because this feature has a lot of different names.interface ethernet 1/g1channel-group 1 mode autoexit!interface ethernet 1/g2channel-group 1 mode autoexit!interface port-channel 1switchport mode accessswitchport access vlan 1 You could be trying to do both create a port-channel that is a trunk port between the two 6200s.  In this case you just change the port-channel switchport mode to "trunk" and add the allowed VLANs to the port-channel.interface port-channel 1switchport mode trunkswitchport trunk allowed vlan add 2 If you are going to create a trunk port between your two 6200s then you dont want to use VLAN1 because a trunk port will not carry VLAN1 traffic.  This is a security feature as its recommended you dont use VLAN1 for anything because some configurations will allow VLAN hopping.  You can overwrite this security feature by using "switchport mode general" but its not recommended. Here is how I might configure two 6200s.  Assuming you dont have them stacked and that your SAN is only in one of the VLANs.hostname SWITCH1!interface ethernet 1/g1channel-group 2 mode autoexit!interface ethernet 1/g2channel-group 2 mode autoexit!interface ethernet 1/g23channel-group 1 mode autoexit!interface ethernet 1/g24channel-group 1 mode autoexit!interface port-channel 1description "TO SWITCH2"switchport mode trunkswitchport access vlan 2,3!interface port-channel 2description "TO SAN"switchport mode accessswitchport access vlan 2! hostname SWITCH2!interface ethernet 1/g1channel-group 2 mode autoexit!interface ethernet 1/g2channel-group 2 mode autoexit!interface ethernet 1/g23channel-group 1 mode autoexit!interface ethernet 1/g24channel-group 1 mode autoexit!interface port-channel 1description "TO SWITCH1"switchport mode trunkswitchport access vlan 2,3!interface port-channel 2description "TO SAN"switchport mode accessswitchport access vlan 2!
New with the Powerconnect series and need help. I have two 6224s with two VLANS setup - default and VLAN2. I have an uplink cable from each VLAN to the other switch. For VLAN2 (ports 1-16), I'd like to truck ports 1&2 on each switch to get double the throughput. I've tried configuring a LAG with ports 1&2 as members on each switch and then assigning the LAG to the VLAN but that didn't work. I think I need the VLAN to be untagged - it's connecting to an EqualLogic SAN that doesn't support VLAN tagging - so I think it should be general not trunk ports. Also tried access but nothing worked. Confused and could really use some help. Thanks.
