I had 6548s. I found out about the ASIC limitation by IOS helpfully telling me when I created the EC "do this and your bandwidth is going to be limited". I read the docs more closely, after a brief bout of kicking self for attempting to save a buck without reading all of the docs. My helpful rep at World Data gave me a decent trade on the 6548s, had 6748s there shortly thereafter, and that was the end of that. Yes you could on a 6548 and just stagger your ports and I believe that will perform fine, assuming you otherwise stay within the card's limitations (e.g. CEF256/8G fabric ports). I would give some thought to the 6816As over the 65116s. They seem to be quite cheap refurb, and otherwise appear to be excellent cards, for which DFC-3Bs don't cost a ton more should you care. Only downside I've seen so far is that switchport vlan mapping applies to all 8 ports on the fabric port/controller, but there appears to be a theme there anyway. -bacon Cisco-using dilettante _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
