redundant connectivity

i have two 4006 distribution switch with 16 (3550 switch) under them and i want to link the 16 access switches to the two 4006 switch redundantly and i am confused on how to do it with the best performance ...

1- connect the 2 GBIC of the 3550 switches one to the 4006 (ws-x4318 module ) and the other to the GBIC port to the other 4006 ( (ws-x4318 module)

2- connect any fast eathernet port from the 3550 switch to both 4006 switches in the (ws-x4124 fx mt module) wihout the need to use GBICs ports and also without the need to have the (ws-x4318 18 GBIC port module).

Can You please advice me what is the right solution ...

and another question ... can i use the ws-x4232-RJ L3 in layer 3 operations instead of using the supervisor engine III

i ll appreciate your help

Re: redundant connectivity

I believe you are referring to WS-X4418-GBIC module as we do not have a 4318 blade. WS-X4418-GBIC is designed for servers(bursty traffic) and not for switch aggregation. On a WS-X4418-GBIC, only ports 1 and 2 are non blocking while ports 3 through 18 are oversubscribed

If you have the luxury, I suggest that you use WS-X4306 modules for aggregation as all ports are non blocking.

Regarding your question on whether to use fastethernet, it depends on your traffic patterns. You cannot use a WS-X4232-L3 module in a CAT4006 with Supervisor 3 Engine. If you are looking for IPX routing support, we have released 12.1(12c)EW today which supports IPX/AT routing
