HPE FlexFabric 5950 Series Command Reference

88
For DHCP requests that do not contain Option 82, the DHCP relay agent always adds Option 82 to
the requests before forwarding the requests 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.
The settings do not take effect even if you configure them.

# Specify the handling strategy for Option 82 as keep.
