[rbak-nsp] SE400 link aggregation problem with load balancing

[Elma K.]

The link is with /30 mask, so I can not take just 1 higher IP... Maybe I can change both IPs on this link, 
but I have to check this with a coleague that works on the other device, to see if this is possible for him.

I will let You know when I get this info. In the meantime, if there is any other idea, I would appreciate it.

Regards
Elma

Hi Elma,



Do you by any change use the same IP address as destination and/or source?

The way the balancing works is based on something like source IP plus destination IP plus destination port, that will stick to the same physical link.

I ran into this problem once, solved the test by adding another source 1 IP address higher and that took another link. 



I don’t know if you have the same kind of trouble there.



Kind regards,





Frans.

Hello.



I have SE400 connected to other device, and I have configured link aggregation on SE400, 

everything works fine except load-balancing from Redback's side... 

Traffic that is going from redback is not balanced on link group members, it is gong only on one port.



I guess there must be some configuration to change the way the device is doing this load balancing

between group members.



My device is with SEOS-2.6.7 (no chance for upgrade, unfortunately)

and the config is like this:



link-group hsiUplink-2PCh ether

 bind interface uplink-2 hsi



port ethernet 1/5

 link-group hsiUplink-2PCh

!

port ethernet 1/7

 link-group hsiUplink-2Ch

!

port ethernet 3/12

 link-group hsiUplink-2PCh

!



Could anyone help me, please?



Best Regards.

Elma
