Linkagg between 2 OS6850

[Alexander]

Hi all!

I need create LAG between two OS6850
First config:

Code: Select all

lacp linkagg 10 size 2 admin state enable
lacp linkagg 10 actor admin key 101
lacp agg 1/44 actor admin key 101

Second config:

Code: Select all

lacp linkagg 1 size 2 admin state enable
lacp linkagg 1 actor admin key 101
lacp agg 1/23 actor admin key 101

But LAG don't work after crossing ports 1/44 and 1/23
First log:

MON NOV 26 13:42:41 2012 LINKAGG info LACP PDUs Miss Reason: Not received - Timeout expired
MON NOV 26 13:42:41 2012 LINKAGG info LACP Link 51 -> 0 is OUT_OF_SYNC agg_id=10

Second log:

MON NOV 26 13:42:40 2012 LINKAGG info Actor & Partner are not matched with lacp activity
MON NOV 26 13:42:46 2012 LINKAGG info LACP PDUs Miss Reason: Not received - Timeout expired
MON NOV 26 13:42:46 2012 LINKAGG info Elapsed timer interval 0
MON NOV 26 13:42:46 2012 LINKAGG info LACP Late time prev_time 1353929716 curTime 1353930166 diff 450
MON NOV 26 13:42:46 2012 LINKAGG info LACPs Late time lacpni_prevtime 1353929716 diff 450 lacpni_lasttick 447
MON NOV 26 13:42:46 2012 LINKAGG info LACP Link 22 -> 1075 is OUT_OF_SYNC agg_id=1

Both lags works fine when I connect each of them to configured linux bond interface.

Thank you

Hi,

In you config, you have only one port on the aggreg whereas you indicates size 2???

Exemple of config on a switch (aggred on port 8/1 and 8/2):
-> lacp linkagg 1 size 2
-> lacp linkagg 1 actor admin key 1
-> lacp agg 8/1 actor admin key 1
-> lacp agg 8/2 actor admin key 1

Had that once with really old switches (was a hardware revision thing when i remeber correct).

I have multiple setups where aggs with 1 Link (size 2) work.

You gort a physical link ? (switch to switch "normally" had to be crossover cables - not sure whether all (older) 6850 hat auto mdix)

Maybe that problem is a result of problem described in first topic? viewtopic.php?f=191&t=20902

Probably.. without having that one fixed i would not try to look for strange lacp issues.
