Difference between WS-X6148-GE-45AF and WS-X6148A-GE-45AF

[Mohammed Nijamuddin]

Similarities between WS-X6148-GE-45AF and WS-X6148A-GE-45AF used commonly in 6500 chassis are many i.e. both of these modules have 48-Port 10/100/1000 RJ-45 Classic Interfaces and 1:8 port mapping to Pinnacle Asic. However below are very remarkable differences.

WS-X6148-GE-45AF: Has shared buffer fo 1 Mb per 8 ports and can support a max mtu of 1518 only

WS-X6148A-GE-45AF: Has per port buffer of 2.67 Mb and can support a max mtu of 9216. Hence this module can handle more bursty traffic etc.

Hi,

I need to know if the VS-SUP2T-10G supports the WS-X6148-45AF linecard.

in the site:

http://www.cisco.com/en/US/prod/collateral/modules/ps2797/ps11878/data_sheet_c78-648214.html

it supports:

WS-X6148A-RJ-45, WS-X6148A-45AF, WS-X6148-FE-SFP, WS-X6148A-GE-TX, WS-X6148A-GE-45AF, WS-X6148E-GE-45AT

our line card is WS-X6148-45AF, what is the difference between WS-X6148-45AF and WS-X6148A-45AF?  Will the VS-SUP2T-10G support it?

"The Supervisor 2T provides backward compatibility  with the existing WS-X6700 Series Linecards (with the exception of the  WS-X6708-10G, which will be replaced by the new WS-X6908-10G, discussed  later), as well as select WS-X6100 Series Linecards only. There is no  support for the WS-X62xx, WS-X63xx, WS-X64xx, or WS-X65xx Linecards"
