Dhcp Snooping Max-Learning-Num - HP MSR Series Command Reference Manual

Predefined user roles
network-admin
Parameters
drop: Drops DHCP messages that contain Option 82.
keep: Keeps the original Option 82 intact.
replace: Replaces the original Option 82 with the configured Option 82.
Usage guidelines
This command takes effect only on DHCP requests that contain Option 82. For DHCP requests that do not
contain Option 82, the DHCP snooping device always adds Option 82 into the requests before
forwarding them to the DHCP server.
If the handling strategy is replace, configure a padding mode and padding format for Option 82. If the
handling strategy is keep or drop, you do not need to configure any padding mode or padding format
for Option 82. The settings do not take effect even if you configure them.
Examples
# Specify the handling strategy for Option 82 in request messages as keep.
