I have a cisco WS-C6509-E with VS-S720-10G (12.2(33)SXI1) and i'm seeing something weird when i do a "show etherchannel summary" command
I am seeing additional port-channels which I have not created.
For example i'm seeing:
699 Po699(SD) -
700 Po700(SD) -
731 Po731(SD) -
732 Po732(SD) -
Is this something to be concerned about how can i remove them?

Hi,
Can you post the output of show ehterchannel summary.
If you don't need it, just remove it by going into all the interfaces associated with these etherchannel:
interface xxxx
no channel-group xxx
After you are done, go to the global config mode and do
no interface port-channel xxx
Verify it by using the show ehterchannel summary command.

I can't remove it because there are no interfaces associated with these etherchannels:
Here is my output:
Number of channel-groups in use: 9
Number of aggregators: 9
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(RU) - Te1/5/4(P) Te1/5/5(P)
2 Po2(RU) - Te2/5/4(P) Te2/5/5(P)
3 Po3(SD) - Te1/7/1(D) Te2/7/1(D)
4 Po4(SD) - Te1/7/2(D) Te2/7/2(D)
5 Po5(SD) - Te1/7/3(D) Te2/7/3(D)
699 Po699(SD) -
700 Po700(SD) -
731 Po731(SD) -
732 Po732(SD) -

Can you do the following for me:
sh run int po 699
sh run int po 700
sh run int po 731
sh run int po 732
The reason I am asking is I tested this in my lab, if you create the etherchannel before you assign the ports into the interface, you will get this result. Here is the output from my lab:
SW2(config)#do sh ether sum
Number of channel-groups in use: 1
Number of aggregators: 1
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
23 Po23(SU) LACP Fa0/16(P) Fa0/17(P)
SW2(config)#int po 3
SW2(config-if)#do sh ether sum
Number of channel-groups in use: 2
Number of aggregators: 2
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
3 Po3(SD) -
23 Po23(SU) LACP Fa0/16(P) Fa0/17(P)
SW2(config-if)#exit
SW2(config)#no int po 3
Rack1SW2(config)#do sh ether sum
Number of channel-groups in use: 1
Number of aggregators: 1
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
23 Po23(SU) LACP Fa0/16(P) Fa0/17(P)
As a result, if you go into the global config mode and do
no int po 699
no int po 700
no int po 731
no int po 732
this should clear those unused/unassign etherchannel.

when i do a:
sh run int po 699
I get the following:
-----------------------------
show run int po 699
Building configuration...
Current configuration : 5 bytes
end
-----------------------------
Each one of the other po's output the same thing.
When i do a no int po 699 in global config mode i get:
---------------------------------------
no int po 699
^
% Invalid input detected at '^' marker.
----------------------------------------
Not sure what's going on

This is very strange. Give this a try in global config mode:
int po 699
exit
no int po 699

Hi,
Just realized something, the etherchannel/port-channel number 699, 700, 731, and 732 are not valid. The valid numbers are 1 - 256. I am not able to find anything which show these port-channels are default command.
One more suggestion, if the switch is not in production, you can try to reload it or upgrade to SXI1. I am hoping the reboot process realized that it is not way to create these etherchannels (out of range channel number) in the config.
HTH,

Are you using WISM modules in the chassis ?
They generate some portchannels by default.

Yes i do have 2 WISM's in my vss environment, and thing that's it. Thanks for you help guys.
