If I understand you correctly you are wanting to add another interface to the Port Channel?  On the PowerConnect switch you use the channel-group to create a port-channel.  It can get confusing.

console# configure

console(config)# interface gi1/0/1

console(config-if-Gi1/0/01)# channel-group xx mode on

 

then the show command

 

console# show interfaces port-channel

Channel    Ports

.......           .....

ch1             Active: gi1/0/1

 

You can only have one port channel on a specific interface.

 

what should I add here

channel-group 46 mode on <--- will this overwrite channel-group 47 mode on

This would overwrite channel-group 46 mode on.  The 46 is just a name that you choose. 

If you are wanting to add more than one interface to the channel-group you can use a range command.

console# configure

console(config)# interface range ethernet g1-2

console(config-if)# channel-group 1 mode auto

Hi

I am sorry for the confusion but what I need is not to add another interface to the port channel. I have one interface 1/xg3 that talks to the Cisco router as it stands only VLAN 147 is allowed to talk to the Cisco router I want VLAN 146 to talk to the Cisco router as well. I did duplicate all 147 settings for 146 apart from

interface ethernet 1/xg3

channel-group 47 mode on

exit

I did create a channel-port for 46 "for vlan 146"..this might all be wrong though ..not sure, but what I want to achieve is to have VLAN 146 talk to the Cisco router over the interface 1/xg3

First, let’s get some definitions.

 

You create a port-channel using the channel-group command – this is used to group multiple physical interfaces together to gain

 

• Increased Availability — If a link within a LAG fails or is replaced, the traffic is not disrupted and communication is maintained (even though the available capacity is reduced).
• Load Sharing — Traffic is distributed across multiple links, minimizing the probability that a single link be overwhelmed.
• Use of Existing Hardware — Firmware replaces the need to upgrade the hardware to higher bandwidth capacity.

Once created you enter that port-channel and configure it as a single interface.

 

Trunking/General Mode – Takes a single physical interface or a single port-channel and allows multiple VLANS/Subnets to traverse.

Based on what you are describing it sounds like you have a port channel set up but you need a trunk/general connection on the single physical interface 1/xg3.  If this is the case then the port-channel you have created is not necessary at this point.

 

Here is an example of setting up General Mode which is a trunking feature on the 6200 switches.

 

console# configure

console(config)# interface ethernet 1/xg3

console(config-if)# switchport mode general

console(config-if)# switchport general allowed vlan add 146 tagged

console(config-if)# switchport general allowed vlan add 147 tagged

console(config-if)# end
