2 OS6250 connected through an aggregated link

[AlainAuer]

Hi,

I have two OS6250 switches connected with an aggregated link. I have configured two VLANs (100 and 101). On one switch, there is an iPBX, and on the other switch, IP Phones are connected. After a while, the IP Phones unregister. There is a keepalive mechanism. The iPBX sends an ARP request, the IP Phone sends his MAC back, then the iPBX sends a keepalive message and the IP Phone sends an ACK message.
So, after the while, when the iPBX sends the ARP request, the IP phone responds, but the iPBX never receive the reply.
When i try to ping the IP Phones from the first switch, no reply is received. I can ping the IP Phones from the second switch (on which the IP Phones are connected), and after that, I can ping the IP Phones again from the first switch.
Thanks for help

What about the MAC-ADDRESS-TABLE? What is the AOS running? Is there any special configuration in place?

Hi benny,

The AOS running is 6.6.2.242.R01

What do you want to know about the MAC-Address Table ?

[benny]

The configuration looks ok.

What I wanted to know regarding the mac-address-table is how it looks "normally" and when you see the issue (to compare it).

Are there any other switches involved / connected to those two switches?

Benny

Hi Benny,

It seems that we found the problem.

AOS 6.6.2.242.R01 is not supported on OS6250-P24 platform.

We upgraded to AOS 6.6.3 R01 and it works fine.

Thanks for help, benny
