1624 Routing Switch Module

I use several 1624's in combination with 2 8606 Core switches in the core / distribution layer. I don't complain about stability, no problem at all. I only think that they are a little old, maybe you'd better look into the

5500 series routing switches. I just purchased 2 5530-TFD's I use them for the core of a satellite office of about 250 people and they look really promising. I have there 2 5530's in the core and the servers are connected to them completely redundant. The access layer is build up using 425's, which I also use in the main office.

The problem with the 55xx models is the fiber port capacity is to low and I don't believe that they do Advanced Routing. That is what is pushing us to the 1624.

Thanks for the info on the stability though.

the new 5530 model has higher fiber port capacity. But you are right that if needing dynamic routing (Rip, OSPF)the 1600 series works great, the 5500 models only suppot static routing at this time.

I am using several (about 10)1612G and 1648T switches, both in pairs (for redundancy) and in triangles/rings with 8610 and 1424T. They are working very well, but if you want to use OSPF and VRRP you MUST use the latest software. There was a nasty bug (uptime counter resetting to 0) in the earlier versions, that would freeze the switch every 49,5 days ! This has now been fixed, and the switches are rock-solid.

What software version, do you need to be at to support ospf. Do you know if the 1648 supports, port filtering and qos tagging on those ports. i.e. port 21,80,23 etc.

I strongly recomend using the newest release (1.2.4.0). Qos is fully supported. IP filtering is there, but in my opinion rather primitive. The manual is here:
