[alcatel-nsp] LAG on 7710 / 7750 ?

[GARCIA DEL RIO Diego]

Hi Oriana,

 

If you're using 100 meg or 1 gig ports, you'll have to set autonegotiate to "limited" at the port level before you can add them to the lag. This is due to the fact that all members of the lag need to run at the same speed.

 

So.. in short:

 

 

This is one port (member of the LAG)

 

    port 1/1/1

        ethernet

            autonegotiate limited

        exit

        no shutdown

    exit

 

 

for a non-lacp lag:

 

    lag 1

        port 1/1/1

        port 1/1/2

        no shutdown

    exit

 

 

for an lacp enabled lag:

 

    lag 1

        port 1/1/1

        port 1/1/2

        lacp active administrative-key 32768

        no shutdown

    exit

 

 

that should do it for an ALU-to-ALU interop ;-)

Subject: [alcatel-nsp] LAG on 7710 / 7750 ?

 

Dear all, 

 

I would like to use LAG between a 7710 SR4 (soon on R7.02) and a 7750 SR7 (R5.10). 

 

Does anyone have experience with LAGs on 7710/7750, on network ports as well as access ports?  If you have an example more detailed (with lacp, and all) that the one in the SR_OS_Interface_Guide, it would be great.

The documentation mentions that the load sharing is executed in hardware, so I suppose that it should work without problem.

 

Thanks a lot.

Kind regards, Oriana
