So what did we do. I used to use a relay type system in 2007-10 in my previous data centre life. It¹s pretty good but a bit ³industrial². It¹s also so 2007 (even 1990) and doesn¹t scale well when you are trying to do 3,000 racks and 6,000 doors per facility. Part of the scaling issue was the door l

I love the MLXe as a platform. Especially for a campus style switch. Also Cisco really isn't expensive. Not for this type of application. A 7606-S can be purchased refurbished for like 90% off list price. The market is seriously glutted with them. Quoting Josh Reynolds : Have you look

Curious if anyone's used the 7280 and wants to share their experience? I'm looking at it primarily for three reasons, MLAG (i.e. multi-chassis LACP), large ARP/MAC table (256k entries) and large IPv6 neighbor table (256k entries). For the table sizes we would like out of one pair of switches, we'd
