CRS-1 8-Port 10 Gigabit Ethernet Interface Module

[jennyjohn]

How much is the back plane speed for a line card on CRS-1? Does using a 8-Port 10 Gigabit Ethernet Interface Module in CRS-1 have an oversubscription of 2:1, like the WS-X6708 in 7209 chassis?

Thanks

Hello Jenny,

yes from datasheet it looks like so

see

or

http://www.cisco.com/en/US/prod/collateral/routers/ps5763/ps5862/product_data_sheet09186a008022d5e9.html

it talks of a 40 Gbps forwarding engine

described here:

so depending on applications you may prefer a 4 10GE linecard

Hope to help

Giuseppe

Thanks Giuseppe,

We have opted to go for ASR-9000 series router (which has a slot capacity for 400Gbps) with the latest released 16-port 10 Gig Card which can provide the full 10 Gig across each port.
