Etherchannel load

Can anybody tell me how to interpret the "load" column from the "show etherchannel port-channel" command? Is it a hex value? Here two examples:

Index Load Port EC state No of bits

------+------+------+------------------+-----------

1 11 Gi2/48 Active 2

2 22 Gi3/48 Active 2

0 44 Gi5/1 Active 2

3 88 Gi6/1 Active 2


Index Load Port EC state No of bits

------+------+------+------------------+-----------

1 55 Gi2/47 Active 4

0 AA Gi3/47 Active 4


Thanks in advance,


Stephan

Hi,


It's actually a binary representation of the distribution method. (Not sure how useful it is but there you go...)


For example, comparing 55 and AA we get:


01010101

10101010


Which is a simple alternation between the ports.


If we compare 11,22,44,88 we get:


00010001

00100010

01000100

10001000


Which again gives a simple alternation between the ports. I guess it may be useful in the case where you have an uneven distribution of ports (and hence an uneven distribution of traffic) - 3 ports gives you the following values: 0x49 0x92 0x24, which in binary is:


01001001

10010010

00100100


Which shows the 3:3:2 ratio of traffic distribution that you'd expect.


HTH
