Are the X6148A cards dedicated 1 gb/s uplink for each port ( shared 32 Gb/s
bus , as long as each port is it's own 1 gb/s still to the 32gb/s bus and
not shared with 7 other ports, so effectively just 125Mb/s per port then if
all used at full/even capacity) ?
I can't really find anything much on
There was a good thread on Cisco-nsp regarding this exact subject recently.
My recollection is that both X6148 and X6148A have just 6 1GB ASICs.
Therefore the over subscription rate is 8:1. The biggest difference between
these LC's is that X6148A will support large MTU whereas X6148 will not.

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

is fine, as long as it's not 1 gb/s per
