This example of the commands configures the DHCP agent to append its
option 82 information to the BOOTP requests, and sets the maximum
length of the client requests to 1220 bytes.

awplus(config) ip dhcp-relay information policy append
awplus(config) ip dhcp-relay max-message-length 1220
Configuring the
Maximum Hop
Count
You may set a maximum hop count for DHCP requests. The relay agent
discards DHCP requests that have hop counts that exceed the threshold.
To set the maximum hop count, use the IP DHCP-RELAY MAXHOPS
command in the Global Configuration mode, shown here:
ip dhcp-relay maxhops maxhops
The MAXHOPS parameter specifies the maximum hop count for DHCP
requests. The range is 1 to 255, and the default is 10. This example sets
the hop count to 25:
awplus> enable
awplus# configure terminal
awplus(config) ip dhcp-relay maxhops 25

Deactivating
