I've a foundry(Bi8K) and Cat65K(MSFC2) connected back to back on a "non
trunk(CSCO)/untagged port(FDRY)" but for some reason can't seem to have
packets go across that link... I mirrored/spaned the ports on the foundry
side and here's what I get when I try to push traffic through that VLAN..
Frame, Time Stamp, DA, SA,
7 00:00:00.000224620 0180C2000000 0030A3389D5F
Type/Length Data Frame Length Status
00 26 42 42 03 00 00 00 00 00 80 00 00 B0 4A 8C F8 04 00 00 00 00 80 00
00 B0 4A 8C F8 04 80 48 00 00 14 00 02 00 0F 00 00 00 00 00 00 00 00 00 D1
BB 7D AF 64 Good Packet
The Mac Frame types is 0x0026
A quick search on google did not reveal anything... any ideas?
