Channel-group Question
Hi
I do have a live network connected to a Cisco switch through 6200 series powerconnect switches, the switch is connected to the router at interface 1/xg3. The thing is the following I have the network
10.10.147.0/24 which can ping the router at 10.10.147.1
now I did add a new vlan 10.10.146.0/24 I can ping the switch I did setup trunks for the interfaces as needed. Devices can ping each other and the switch on this network, but they can NOT ping the router at 10.10.146.1
10.10.146.1 and 10.10.147.1 on the Cisco router are on the same physical interface with the former being a secondary IP.
I did replicate all147 settings on the switch until I got to the below :
interface port-channel 47
description 'to-Cisco-ASR'
switchport access vlan 147
here I added
interface port-channel 46
description 'to-Cisco-ASR'
switchport access vlan 146
The last part is as follows :
interface ethernet 1/xg3
channel-group 47 mode on
exit
here I need to add the port channel 46 to the channel-group 47, I do not want to mess things up so I need help here, if I execute in configure mode :
interface ethernet 1/xg3
what should I add here
channel-group 46 mode on <--- will this overwrite channel-group 47 mode on
is there something like
channel-group rabge 46,47 mode on
Please advice and thanks a million.

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
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
