Hello,
The B5 resources allow for only 256 DHCP addresses to be handed out.
The DHCP server capabilities on the B5 switch are designed for small remote office locations.
If you wanted to hard set a port to 100 meg full duplex you would issue the following 3 commands:
set port speed ge.1.1 100
set port duplex ge.1.1 full
set port negotiation ge.1.1 disable
