14.1.2 Configuring the DHCPv4 Layer-2 Relay Agent (DHCPv4L2RA)
When DHCPv4L2RA is enabled, the ZXA10 C300 adds DHCPv4L2RA Option 82 field to
the upstream DHCP packets.
Context
The DHCPv4L2RA Option 82 field contains CID and RID, which includes the shelf number,
slot number, and port number.
l
Only when
v4L2RA is enabled, the Option 82 field can be added/stripped
to/from the DHCP packets.
l
When DHCPv4L2RA is disabled, the ZXA10 C300 transparently transmits or directly
forwards the DHCP packets without any processing.
The global DHCPv4L2RA function and VLAN DHCPv4L2RA function are mutually
exclusive.
Configuration Data
