Description: Number of snooped DHCP client packets that were discarded because they were received on an untrusted port and contained a relay information option.
What is hpicfDhcpSnoopCSUntrustedOpt82s?
This counts DHCP client packets dropped because they arrived on an untrusted port while already carrying a relay-information (Option 82) option, which untrusted clients aren't supposed to insert themselves. A climbing value suggests a device is trying to spoof or manipulate Option 82 data from a client-facing port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.5.1.34.1.2.1.3 snmpwalk -v2c -c public <target> HP-ICF-DHCP-SNOOP-MIB::hpicfDhcpSnoopCSUntrustedOpt82s
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.5.1.34.1.2.1.3.1 snmpget -v2c -c public <target> HP-ICF-DHCP-SNOOP-MIB::hpicfDhcpSnoopCSUntrustedOpt82s.1
