Hello all, I have 2 win2k servers with 3com 3C996 Gigabit Cards attached to a cisco 6509 with a WS-X6408-GBIC 8 port gigabit module. I have turned off trunking and channeling on the two ports on my 6509 and I have enabled jumbo frames which is supposed to set the mtu size to 9216. They are also in their own vlan and the mtu in the vlan is set to 9216 as well. On the 3com cards themselves, when I try to raise the mtu above the standard 1500, I get Giants on my switch. It is like the 6509 is not really allowing packets over the 1500 mtu size even though the jumbo frames are enabled. Any ideas? Here is the show port jumbo command which verifies that my 2 ports are enabled for jumbo frames.
6509> (enable) show port jumbo Jumbo frames MTU size is 9216 bytes. Jumbo frames enabled on port(s) 9/2-3.
