1. WS-X6548-GE-TX VS WS-X6748-GE-TX
The difference between WS-X6548-GE-TX & WS-X6748-GE-TX
WS-X6548-GE-TX uses Centralized Bus Forwarding as opposed to CEF720 Bus
Forwarding used on WS-X6748-GE-TX.
The CEF720 uses 2x20Gbps connection to the switch fabric, which on this case is the
Sup Module (no need for a switch fabric module).
WS-X6548-GE-TX is only 1MB buffer per port while WS-X6748-GE-TX is 1.3MB buffer
per port.
WS-X6548-GE-TX is a hybrid, it supports backplane connection in switch fabric or bus
mode while WS-X6748-GE-TX can only support switch fabric.
Personally, I see WS-X6748-GE-TX, the module of choice if you have a Sup720 since it
uses the ideal Bus Forwarding for this hardware.
WS-X6748-GE-TX: Supervisor Engine 720, 720-10GE and 2T-10GE.
The WS-X6748-GE-TX is not supported in the Catalyst 6503 switch chassis. The WSX6748-GE-TX module can occupy any slot in any other Catalyst 6500 or Catalyst 6500-E
chassis except the Catalyst 6513 chassis where the module must be installed in slots 913. The module does not power up when it is installed in slots 1-8.
WS-X6748-GE-TX ships with the WS-F6700-CFC daughter card factory-installed. The
module can be upgraded in the field to support the WS-F6700-DFC3A, WS-F6700DFC3B, WS-F6700-DFC3BXL, WS-F6700-DFC3C, WS-F6700-DFC3CXL, WS-F6KDFC4-A, or the WS-F6K-DFC4-AXL daughter cards.
