Just a note: that 128Gbps looks to me like a 'true marketing number', because of what ex-series show in cli is 32Gbps: s...@switch> show interfaces vcp-0 Physical interface: vcp-0, Enabled, Physical link is Down Type: 105, Link-level type: 70, MTU: 1514, Speed: 32000mbps Well, there are two virtual-chassis interfaces, and they have both input and output directions, and 32G * 2 * 2 is really 128Gbps of marketing... Or am I wrong, and virtual-chassis really can do 128Gbps full-duplex on both ports ? And, anyway, 32Gbps is still better than 10Gbps and saves uplink ports. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
