All,
Anyone knows the oversubscription ratio of WS-X6748-GE-TX and WS-X6148-GE-TX?
Thanks.

The WS-X6148-GE-TX is a classic line card ie. it only has access to the 32Gbps shared bus. This bus is shared by all classic line cards so it's difficult to say what the oversubscription ratio is as it depends on what else is in the chassis.
The WS-X6748-GE-TX has 2 x 20Gbps to the dedicated switch fabric and it has 48 10/100/1000 ports so if you run all 48 ports at 1Gbps there is a slight oversubscription but it is unlikely you will ever get all 48 ports running at 1Gbps at the same time.
