Hi,
Can anybody tell me what is the difference between a Port Channel and an Etherchannel.

Hi
An etherchannel bundles individual physical links into one logical link to increase the total bandwidth. It also seen as one link by Spanning tree algorithms.
A port channel is the logical representation of the etherchannel on the switch. Once you have configured an etherchannel you make all you changes on the port channel interface and these will be automatically applied to all the individual interfaces within the etherchannel.

Hi,
Can you refer to any link on cisco that describes the difference.

Hi
Here is a link for understanding and configuring etherchannel on the 6500 switches. Don't worry too much about it being for the 6500, the same principles apply on other switches.

Hi,
I think having a look at the following links, you can make out the difference.

Hi, sorry if i go a little bit off-topic about this but here i can read :
It also seen as one link by Spanning tree algorithms.
And this is also what i should expect looking at official documentaion.
However i'm experiencing a strange behaviour with a PortChannel , a bundle of 2 GE, in trunk mode in wich when 1 of the two interface goes down SPT is recalculated for each VLAN allowed on the trunk.
Cheking both ends of the Port Channel i see that on one side i've got "switchport mode trunk" while on the other there is not. Checking interface status i see that trunk is working , obviously , but on one side is in
Administrative Mode: dynamic desirable
Operational Mode: trunk (member of bundle Po110)
while on the other side is both "trunk".
can be this the problem?
Bye

What models of switch are at either end of this etherchannel? IOS? CATOS?
