2960S cross stack etherchannel limit

[jpbtimbol16]

I have 2 existing 2960S switches stacked together, with 6 active port channel groups. Each channel group has 2x1GE links in a cross stack etherchannel fashion. Is it possible to add another channel group? Because from specs of 2960S, etherchannels are limited to 6. But what if stacked? Does it mean that I could activate up to 12 etherchannels? And also, I want to use the 2 1GE uplink SFP slots via fiber as an etherchannel. Are all these possible? Thanks in advance!

If I remembered correctly, only 6 EtherChannels are supported. Nothing more.

Ok, thanks! So regardless if I have 4 or 8 2960S switches stacked, I will still have the limit of 6 channel groups?

Hi,

Yes, Cisco is clearly mentioned that "Do not try to configure more than 6 EtherChannels on the switch stack."

Hi, thanks for the help!

Remember, generally when you stack switches, one stack member is acting as master for whole stack, so that's likely why adding additional stack members wouldn't boost the number of port-channels allowed.
