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 etherchannel
It'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.
