Hi Mounir,
I used the command "sh etherchannel port-channel" to check the load across
each physical link of the etherchannel. I checked a few etherchannels
(mostly 4xGE) in my network and noticed the load is always 11,22,44,88, as
follows:
------------------------------------------------------------------------
C6509#sh ether port-channel
Channel-group listing:
-----------------------
Group: 1
----------
Port-channels in the group:
----------------------
Port-channel: Po1
------------
Age of the Port-channel = 190d:11h:50m:39s
Logical slot/port = 14/1 Number of ports = 4
GC = 0x00010001 HotStandBy port = null
Port state = Port-channel Ag-Inuse
Protocol = PAgP
Ports in the Port-channel:
Index Load Port EC state No of bits
------+------+------+------------------+-----------
0 11 Gi5/1 Desirable-Sl 2
1 22 Gi5/2 Desirable-Sl 2
2 44 Gi6/1 Desirable-Sl 2
3 88 Gi6/2 Desirable-Sl 2
Time since last port bundled: 69d:13h:32m:15s Gi5/1
Time since last port Un-bundled: 69d:13h:32m:20s Gi5/1
------------------------------------------------------------------------
Can someone help to explain why?
Thank you.
B.Rgds,
Lim TS
