Solved: GE module in Catalyst 4500 family

rainman36 · ‎07-03-2005

I want to connect 18 GBIC in my Edge switch to one Catalyst 4506 in Distribution Layer. can I use 18 port Gigabit Ethernet Module, server switching (WS-X4418-GB) or I have to use 3x 6port Gigabit Ethernet Module (WS-X4306-GB).

Thanks for your help.

Hi,

Please note that the WS-X4418-GB has an oversubscribed ports with a value of 4 to 1, you can think of it as if every 4 ports share the same bandwidth of the line bus, so it is better to use the WS-X4306-GB, another advantage is that if this module fails, only 6 links would suffer, not 18 links.

Thanks,

Jawad

In a WS-X4418-GB the first 2 ports are wirespeed and have no oversubscription.

You will be better off using these 2 ports to connect to your 4506.
