I'm not sure, but I thought I read somewhere that the GigaStack GBICs are half duplex. I think I read somewhere that you shouldn't use them in an environment that requires QOS. If this is true, your throughput would be better with 1000B-T GBICs or Fiber GBICs running at full duplex.

Using Gigastack, can both slots be used as "Gigastack Etherchannel" (ie all four ports (two on each module)) to provide 4Gb link. Scenario would be a 3508 with two Gigastack modules and 3548 with two Gigastack modules - connected with four gigastack cables. Various web pages show 2Gb full duplex using Gigastack and also mention 4Gb Full Duplex using Gigabit Ethernet. Even though the latter was on a Gigastack data sheet, it was worded as though (or could mean) an alternative was to use Gigabit Ethernet at 4Gb. Hopefully I've got the question over - Basically, I know 4Gb is possible with fibre SX/LX etc, but what about Gigastack?
