I can't really find anything much on X6148A internal architecture online, but it would seem that each port gets its own 1gb/s link to the card/backplane, and that the bottleneck then is the 32gb/s backplane (which is fine, as long as it's not 1 gb/s per each set of 8 ports!).
Sadly, it is 1Gb per each set of 8 ports. The WS-X6148-GE-TX line card has its uses, just not in the data center. To recap on the thread a couple of weeks ago:
- no storm control - no port security- 1G aggregate traffic for each group of 8 ports (i.e. think of it as 6 x gigabit ethernet hubs with shared input buffers connected into a 32G backplane)
- 2 ports per etherchannelIt's not a service provider blade and doesn't belong in a data center switch setup. Don't be disappointed by this: it was designed to be an aggregation blade for enterprise desktop usage and is quite useful in that context.
