Nope, auto-MDI/MDIX is suggested, but not mandatory for 1000BaseT. In practice, just about every single gig port has it, except for Cisco, which several devices/ports did not. Always good to have the full 4-pair crossover cables around Cisco gear just to make sure. (and important to check on your crossover cables, as many vendors borked out on making them, and didn't cross all 4 pairs, causing no end to fun troubleshooting *that*). _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
