issue with VLAN and LAG between two switchs
Hi,
I spent a lot of hours to find a resolution but i have to admit that i won't find one alone. I have two switchs Dell PowerConnect 6248 and try to communicate between them in a VLAN.
I created one VLAN ID 3 on the two switchs. I tagged the interconnection port 41-48 (with LAG and LACP enabled) in trunk mode on VLAN3 on both. I declared a untagged port n° 10 and the first switch. There is a Wifi access point plugged on it. On the second, i tagged the port n°10 on VLAN3. A router is plugged on this port.
From the router, i can ping VLAN3 interface of the second switch. But not the first.
From the first switch, i can ping the access point but i can't ping the VLAN3 interface of the second switch. It seems the two switchs can't communicate on VLAN3 between them.
Can someone help me please ? Here is the two config :

Hi, i think i found the problem :
Channel Ports Hash Algorithm Type
------- ----------------------------- -------------------
ch1 Active: 1/g43, 1/g44, 3
1/g45, 1/g46, 1/g47, 1/g48,
1/g42, 1/g41
Hash algorithm type is 3 and i suppose 802.11q is not forwarded in the lag. Which type you advise me please ? Can i change the algorithm in production ?
Thank you.
