I am trying to up the MTU for MPLS. Any way to do this manually or is this something that's supported in hardware and automatically upped slightly if a port were a trunk port, for example? Trying to avoid purchasing WS-X6516-GE-TX or WS-X6748-GE-TX if possible. _______________________________________________ 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/ _______________________________________________ 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/
