4.7.3.1 DHCP option 82 management
The DHCP option 82 is configured via the profile system –
profile
dhcp-opt82
. The system allows to create
several different profiles and assign them not only globally to all DHCP packets in general, but also to separate
profiles by VLAN.
Step 1.
Create DHCP option 82 profile using the
profile
dhcp-opt82
command. Pass profile name as a
parameter.
LTP-16N# configure terminal
LTP-16N(configure)# profile dhcp-opt82 test
LTP-16N(config)(profile-dhcp-opt82-test)#
Step 2.
Assign the global profile, using the
opt82 profile
command in
ip dhcp view
.
LTP-16N(configure)# ip dhcp
LTP-16N(config)(dhcp)# opt82 profile test
Step 3.
Assign another profile to the VLAN if needed.
