me1200DhcpRelayGlobalsInformationMode
Module: ME1200-DHCP-RELAY-MIB
OID (symbolic): ME1200-DHCP-RELAY-MIB::me1200DhcpRelayGlobalsInformationMode
OID (numeric): 1.3.6.1.4.1.9.9.815.1.55.1.2.1.3
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Indicates the DHCP relay information mode option operation. Possible modes are - Enabled: Enable DHCP relay information mode operation. When DHCP relay information mode operation is enabled, the agent inserts specific information (option 82) into a DHCP message when forwarding to DHCP server and removes it from a DHCP message when transferring to DHCP client. It only works when DHCP relay operation mode is enabled. Disabled: Disable DHCP relay information mode operation.
What is me1200DhcpRelayGlobalsInformationMode?
A read-write boolean enabling DHCP Option 82 (relay agent information) insertion; when true, the switch inserts option 82 into client requests forwarded to the server and strips it from server replies before passing them to the client, letting the DHCP server identify which port/VLAN a request came from.
