3 Configuring the Switch

•Drop – Discards the Option 82 information in a packet and then floods it to the entire VLAN.

•DHCP Relay Server – IP addresses of DHCP servers to be used by the switch’s DHCP relay agent in order of preference. Up to five servers can be specified.

Web – Click System, IP Configuration. Enable the DHCP Relay Option 82 function, set the Option 82 policy, and specify at least one DHCP server IP address. Click Apply.

Figure 3-8 DHCP Relay Option 82 Configuration

CLI – This example enables DHCP relay with Option 82, and sets the policy as replace.

Console(config)#ip	dhcp relay server 192.168.1.9 192.168.1.54
Console(config)#ip	dhcp relay information option	4-241
Console(config)#ip	dhcp relay information policy replace	4-242
Console(config)#exit
Console#show ip dhcp-relay
Status of DHCP relay option82:
Insertion of option82 is Enabled.
DHCP option policy	:replace.

DHCP relay-server address 192.168.1.9 192.168.1.54 0.0.0.0 0.0.0.0 0.0.0.0
