What is tnDhcpSnoopingStatisticsInterfaceRxDiscardUntrust?

This read-only counter tallies DHCP server-side packets (e.g. OFFER/ACK) received on this port and discarded because the port is configured as untrusted. A rising count is a direct signal that DHCP snooping is actively blocking a rogue or unauthorized DHCP server on this port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.147.1.5.2.1.15
snmpwalk -v2c -c public <target> TN-DHCP-SNOOPING-MIB::tnDhcpSnoopingStatisticsInterfaceRxDiscardUntrust

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.147.1.5.2.1.15.1
snmpget -v2c -c public <target> TN-DHCP-SNOOPING-MIB::tnDhcpSnoopingStatisticsInterfaceRxDiscardUntrust.1
