"Users can achieve even higher levels of performance in their full-duplex stacks by configuring dual links from an aggregation switch to each stack member. The two Gigabit Ethernet ports on each Catalyst 3550 Series switch can be grouped together using Gigabit EtherChannel® technology to create a stack connection with a full-duplex 4-Gbps forwarding rate."
However, if i try to create the channel it says:
000055: *Mar 1 08:55:42: %EC-5-UNSUITABLE: Gi0/7 will not join any port-channel, GigaStack GBICs are not allowed to be part of an etherchannel
000056: *Mar 1 08:55:42: %EC-5-UNSUITABLE: Gi0/8 will not join any port-channel, GigaStack GBICs are not allowed to be part of an etherchannel
Strangly enough, the other site, of the gigabit etherchannel in spe, which is a 2950G doesn't give the error message.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
