Difference between two 6500 modules.

[andrewleki]

What would be the main difference (except the price)

Between those modules:

WS-X6148-GE-TX=

Catalyst 6500 48-port 10/100/1000 GE Mod., RJ-45

and

WS-X6548-GE-TX=

Catalyst 6500 48-port fabric-enabled 10/100/1000 Module

I believe the first module is used on a non fabric enabled chasis which means the backplane capacity of the switch is 32 Gbps

The second module is fabric enabled so if you have a switch fabric module then this module can connect to the switch fabric with a capacity of 256 Gbps

The following link described the switch fabric architecture:

If I use a supervisor 720, switch fabric is also enabled. isnt it?

So when I use the second module, al the interfaces on this card would be non-blocking, correct?

I really need some ports on the core for out dedicated server that have a non-blocking connection

Hi,

Yes if you use sup720, it will enable switchi fabric.

But enabling switch fabric doesn`t mean that ports on a line card will acquire non-blocking architecture. It depends on the design of the line card, how the ports are divided in a gourp of ASICs. $nabling the fabric channel means that line card would increase the communication speed to backplane of its chassis.

On WS-X6548-GE-TX , the port arrangement is :

Number of ports: 48

Number of port groups: 2

Port ranges per port group: 1-24, 25-48

It will work on a blocking architecture. You may go for WS-X6748-GE-TX , its port arrangement is :

Number of ports: 48

Number of port groups: 4

Port ranges per port group: 1-12, 13-24, 25-36, 37-48

less ports per ASIC would give enough room to data to be stored and forward.

Hi,

So what do I need on my core if I need 13 non-blocking gigabit UTP interfaces?

[aashish.c]

Hi

as per best of my knowledge there is n line card available which gives 19 non-blocking Rj-45 UTP ports.

But how much data those servers will throw? I do not think that servers should cause any trouble if you use "WS-X6748-GE-TX " . As it is fabric only line card which means it has 2 connections each of 20Gbps full duplex connection to switch fabric. It will communicate at 80Gbps full-duplex with the chassis. and it requires to have sup720 only.

data will be switched internally, at a faster rate than any CEF256 enable card i.e. 6548-GE-TX.

Aashish,

If I connect only 19 ports on the X6748-GE-TX module those ports would still be non-blocking?

Is it true I can use max. 32 ports to keep this module in non-blocking state?

[aashish.c]

Hi,

WS-X6148-GE-TX= is a classic line card has a shared bus connector and will only work with shared 32gbps bus. It doesn`t have any connection switch fabric.

WS-X6548-GE-TX= is fabric enables line card with CEF256 architecture. It has a shared bus connector and one 8Gbps full-duplex connection to switch fabric channel, if SFM used.

Hope this clarifies

Hi,

as the module WS-X6748-GE-TX has a 2*20GB link the the sup720 switch-fabric engine I would be able to connect some ports at non-blocking on this module

wouldn't I ?
