[c-nsp] WS-X6148-GE-TX limitation

[Everett Dowd]

I got bit by that same bug on our 6500's. It is a limit of the card itself
and is documented (you really have to look for it though)... This card is
based on an 8:1 oversubscription and you can actually rob bandwidth from the
other seven ports is one is pushing packets at a high rate. 

Of course you can always move to the 6748, and the SUP 720 if you really
want throughput. We moved back to the 16 port gig cards so we could up the
bandwidth on the 6500.

Hi all :)

I have several routers (7600 family) with this module.
I can see there is a limitation as shown in 
http://www.cisco.com/en/US/customer/products/hw/routers/ps368/products_confi
guration_guide_chapter09186a0080160eb8.html

"The WS-X6148-GE-TX and WS-X6148V-GE-TX switching modules do not support 
more than
1 Gbps of traffic per EtherChannel."

When I bought this equipment in Cisco, they told us nothing about this 
limitation (they know that we need etherchannels supporting more than 
2-3 Gb)

Is it at last a problem with the switch fabric or more related to the 
IOS that support it?

Cheers
