Usage Guide: When a DHCP/BOOTP client is connected to a VLAN1 port of the switch, the client can only
get its address from 10.16.1.0/24 instead of 10.16.2.0/24. This is because the broadcast packet from the
client will be requesting the IP address in the same segment of the VLAN int erface after VLA N interface
forwarding, and the VLAN interface IP address is 10.16.1.2/24, therefore the IP address assigned to the client
will belong to 10.16.1.0/ 24.
If the DHCP/BOOTP client wants to have an address in 10.16. 2.0/24, the gateway forwarding broadcast
packets of the client must belong to 10.16.2. 0/24. The connectivity between the client gateway and the switch
must be ensured for the client to get an IP address from the 10.16.2. 0/24 address pool.
