The Moderator mentions "The switch's architecture has ports 1-24 and gigabit port 1 on 1 ASIC, while ports 25-48 and gigabit port 2 are on the other. Because of this architecture, you are unable to mirror between ASICs, e.g. port 1 to port 48." He also mentions a hardware chipset limitation that only affects the Dell 33xx series regarding mirroring of ports that are part of a 802.1Q VLAN.
