x670 trunk link

Amir_A_N — Tue, 21 Feb 2017 19:30:00 GMT

Hello everyones!

I wanna buy a x620 extreme switch with 16 10G ports. I need 2 trunk links including 4 ports each as a lacp LAG. The question is can I configure following properties on it or not:
1-Making more than 8 LACP port in a trunk link
2-Decreasing LACP time out

I did all of these configuration on x670 with 48 10g ports but I am not sure about x620 series.
Thank you so much.

Hello, Amir!

EXOS RelNotes - maximum number of ports per loadsharing group for X620 is 8 ports.
You can add more then 8 ports - till 16, but they wouldn't be in UP state, they will be standby links.

You can configure lacp timeout with command
configure sharing port lacp timeout [long | short]
long - 90 sec
short - 3 sec

Thank you!

Thank you Alex!
I have configured more than 8 active ports on x670 series and also it is equipped with an EXOS version 16. Are you advising from the perspective of EXOS or the x620 platform?
what is your opinion about making trunk ports?

Amir!

X670 give possibility to make 1 trunk with more then 8 active ports but more expencive.
X620 give only 8 ports in 1 trunk but more cheaper.
Numbers of active ports in 1 trunk don't depends from EXOS version (if we talk about 15.x; 16.x; 21.x versions) it's depends from hardware.

You have to decide what is better for you.

Thank you!

As a side note here, the x620 is a 10 or 16 ports switch. Going above 8 ports per LAG doesn't make a lot of sense, non-LAG ports would be less...
