Hi all
Just ran into a small problem here.
I've got 6 2960G that Im building a backup network with.
One is the "Core-2960G" which i connect the remaining 5 2960G to.
All 2960G uses etherchannel with two links for more uplink speed to the "core 2960"
I just noticed that Im only allowed 6 etherchannel groups in a 2960G?
Im going to use atlest 5 groups connecting all the switches to my core.
And I also need alot more etherchannel groups for the servers that needs 2 port bundled conneced to the switch.
I've scanned through the 2960 documentation but never found the maximum number of etherchannel that it supports?
Current setup
Core-2960 <-> 2960-1 Etherchannel group 1
Core-2960 <-> 2960-2 Etherchannel group 2
Core-2960 <-> 2960-3 Etherchannel group 3
Core-2960 <-> 2960-4 Etherchannel group 4
Core-2960 <-> 2960-5 Etherchannel group 5
This leaves me with 1 remaining etherchannel! And I need atlest 5 more!
What can I do?
Thanks!

I use the 3560. They kind of hide that info on you. The only place I could ever find it is in the configuration guide. For example for the 2960, in the config guide, it states-
Specify the channel group number. The range is 1 to 6.
For the 3560-
Specify the channel group number. The range is 1 to 48.
I can not verify it supports 48 channel groups, but I know it supports more than 6!
Hope that helps

I ran into the same problem and that's why I no longer have 2960's in the network. If you have to use etherchannel, you'll have to buy a switch that supports more than 6.
Hope that helps.

What switch do you use instead?
I cant find a link/information regarding how many etherchannels the different switch models can use/is restricted to.

I can verify that the 2960 is only 6 channels , we just ran into the exact same thing and we have to replace the switches too. We are also optioning for a 3560 for the replacement. 6 seems small specially if you have the 48 port 2960 .
