tnDhcpSnoopingConfigGlobalsMode
Module: TN-DHCP-SNOOPING-MIB
OID (symbolic): TN-DHCP-SNOOPING-MIB::tnDhcpSnoopingConfigGlobalsMode
OID (numeric): 1.3.6.1.4.1.868.2.5.147.1.2.1.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Indicates the DHCP snooping mode operation. Possible modes are - true: Enable DHCP snooping mode operation. When DHCP snooping mode operation is enabled, the DHCP request messages will be forwarded to trusted ports and only allow reply packets from trusted ports. false: Disable DHCP snooping mode operation.
What is tnDhcpSnoopingConfigGlobalsMode?
This read-write flag globally enables or disables DHCP snooping on the switch: true forwards DHCP requests to trusted ports and only allows DHCP reply packets from trusted ports, while false disables the feature entirely. Enable this to block rogue DHCP servers on untrusted (access) ports from handing out bogus leases.
