Hi,
we have cisco 6509 switch with ws-x6748-GE blade
We have configured layer2 portchannel with a HP blade switch
channel-group mode is set to 'Active'
Portchannel establishes but I could see several portchannels are created
Pasting the sh etherch summary. You can see po21A, po22A and po22B created
The individual ports are fine and are passing traffic. Can someone help me in getting only one po21 or po22 and also why po21a , po22a and po22b created
Switch1#sh etherch summ

M - not in use, no aggregation due to minimum links not met

w - waiting to be aggregated

Hi,
What version of IOS are you running?
That command usually shows the portchannel you created (21 in your case) and not all the internal once.
It usually looks some thing like this:
xxxx-Switch(config-if)#do sh etherc s
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 1
Number of aggregators: 1

xxxx-Switch(config-if)#

IOS 12.2(17R)SX5. Yes I agree the output should be like yours, but I am not getting them hence this discussion |

Usually that means your port channel configs do not match on each end . Something in your configs on either the cisco or hp do not match. If you are trunking across the channel all your trunking parameters must match. Also when you configure the channel , have them shutdown and then bring your ports up via the port channel SVI doing a no shut. You may have to delete the current ones and recreate them .
