can not create Channel-Group between two switches PC5524

Hi Daniel!

The problem is that i'm not forming port-channel between two switches.

I don't want those ports to be part of any VLAN...but i can not remove that settings.

So, my two switches, fail to form portchannel with each other.

So you want one port from one switch to connect to one port on the other switch? I am not real clear on what you want to accomplish here.

That is what I thought you were trying to do but then you said "i'm not forming port-channel between two switches." At that point I was unsure.

Once a port is placed in a channel-group it ignores all other config settings applied to that specific port.  So in your config:

interface gigabitethernet1/0/1

# channel-group 1 mode on

# switchport mode trunk (this part is ignored because the port is in a channel-group)

# switchport access vlan 6 (this part is ignored because the port is in a channel-group)

If to clean up the config you want to remove those settings from the port, you first need to remove it from the channel-group. Then remove the setting you want.

# interface gigabitethernet1/0/1

# no channel-group 1 mode on

# no switchport mode trunk

# no switchport access vlan 6

# channel-group 1 mode on

# exit

To place a port into a channel-group and then configure the channel group the config would look similar to this.

# interface gigabitethernet1/0/1

# channel-group 1 mode on

# exit

# interface gigabitethernet1/0/2

# channel-group 1 mode on

# exit

# interface  port-channel 1

# switchport mode access

# switchport access vlan 6

I've said it by words:

i want to configure portchannel between two switches PC5524.

THe portchannel must be configured on two ports gi1/01 and gi1/02 (for redundancy and loadbalancing).

The problem is that with configuration i've listed on my frist post, this portchannel is not running.

See the image below.

You can use Access, General, or Trunk mode. What i gave was just an example. The point to take away is that the config needs to be given to the port-channel, not the individual interface.

On = static

Auto = LACP

which is recommended...ON or Auto???

why you suggest this on last:

# interface  port-channel 1

# switchport mode access

# switchport access vlan 6

i thought we have to put the command:

# switchport mode trunk

not access.

also...what about the command

# channel-group 1 mode on

it must be like that or like this:

# channel-group 1 mode auto?

Auto, LACP is what i would recommend.
