We use the following configuration:
Two 8610's connected by a two-fiber MLT, running version 3.7.16.0.
VLANs 7, 15, 32, 200 span across the two 8610s.
A load balancer model 2208 (running OS Version 23.0.3.4) is connected via a single data port of the 2208 to 8610-1. This port is defined as tagged, assigned to VLANs 7, 15, 32, 200 and is serving both SLB client and server requests.
A single management port of the 2208 is also connected to 8610-1, on VLAN 200.
All works well under the above conditions.
In future, we plan to connect a second 2208 data port to 8610-2 and run the 2208 in SMLT mode.
We run into problems when we change the 8600 configuration from MLT to IST. (Still using only a single 2208 data port).
The problem is manifested, to use one example, by 8610-1 not being able to ping 8610-2.
Checking the ARP table of 8610-1, the IP and MAC addresses of 8610-2 point to the 2208 data port location (instead of the IST port). When the 2208 data port is disconnected, the ARP table changes to the correct position (points to an IST port) and the ping resumes. When the 2208 is reconnected, the same phenomena recurs.
When the 8610s change back from IST to MLT configuration, the problem disappears and everything returns to normal.
Are there any suggestions how to trouble shoot this?
Thanks!
