They do have DBus connectors. Even the WS-X6708-10G-3C, even though the diagram doesn't show it. http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/prod_white_paper0900aecd80673385.html#wp9000639 > As a further question, assuming they do send lookups across the shared > bus then having classic linecards using the same bus could have a > direct impact on the performance of the 67xx modules ? AFAIK it will not impact the performance of traffic staying on fabric-enabled cards. (I'm not aware of any changes the Sup2T might introduce here.) -- Peter _______________________________________________ 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/
