Poor tiny asics... this is why people buy 6509-sup720's with 6748 DFC3 line cards (not 6548 which also have tiny ascis)... sorry "you are your buffers" on that thing...
It's a "WIRING CLOSET SWITCH" regardless of fancy blades and port speeds...

Subject: OT: Transmit drops
I have an hp switch uplinked to a Cisco 4506R over 10GB ethernet. This link averages about 600Mb of traffic but spikes up to around 1.5Gb. I've never seen it spike over 2Gb per sec. The thing is this connection seems to have a high number of transmit drops. Looking at the current statistics on the interface statistics I see 3.5 Billion total frames with 440 million transmit drops so over 10%. Why would an interface that is never maxed seem to be dropping so many packets?
I don't see any errors that would make me suspect a bad cable or anything, no FCS runts, giants, or collisions.
There is no queuing on this interface, would that help the situation?
