Hi Everyone,
I am new to linkagg in alcatel.
We have 2 6900 switch configured as VC and they have linkagg to uplink switches.
when I run the command
show linkagg agg 1 port
Chassis/Slot/Port Aggregate SNMP Id Status Agg Oper Link Prim
-------------------+----------+--------+----------+----+-----+-----+----
1/1/1 Dynamic 1001 ATTACHED 1 UP UP YES
2/1/1 Dynamic 101001 ATTACHED 1 UP UP NO
Need to know if Data traffic is going via both ports 1/1/1 and 2/1/1?
Is spanning tree in forwarding state on both 1/1/1 and 2/1/1?
Also why port 2/1/1 is marked as no primary?
Regards
Mike

Re: What traffic does Non Primary port passes in linkagg
Sessions are split/hashed across all active links.
This will be per Source/Dst MAC or IP or.. means traffic from one Host to another will only use 1 link. if you have lots of different traffic it will probably be a equal distribution.
Primary link is the first active port of an lacp - this carrys per default traffic like multicast, stp aso (it's in the manuals.. read there)
There will be traffic on both interfaces
show interfaces 1/1/1
show interfaces 2/1/1
STP will only have the "virtual" interface "1" of the lacp, the physical ports are no longer particitpating stp. (as you only configure vlans on the agg 1 no longer on the member ports)

hi,
So which command I can run on the the switch to check stp status for linkagg 1 or virtual link ?
I can see the traffic coming via both links in linkagg.
Can you please point me to link or tell me which traffic goes via primary link and which traffic goes via non primary link?
Regards
Mike

Re: What traffic does Non Primary port passes in linkagg
Please: Take some basic Alcatel workshop and/or read the manuals.
Traffic of multiple source/Destination pairs will be hashed over all available links. i do not think you can see which link certain traffic uses by looking at it.
Certain traffic (Multicast/broadcast) is per default only transmitted via primary port
(there is an option to hash/distribute that traffic as well (manual)
show spantree port 1
(or similar)
should show you the stp state of linkagg 1
