Description: The number of BOOTP/DHCP multicast request packets received by the relay agent.
What is hmRelayMCPktInCnt?
This object counts the total number of multicast BOOTP and DHCP discovery request packets received by the DHCP relay agent on a Hirschmann device. These are broadcast messages from DHCP clients seeking a DHCP server. An operator would monitor this counter to verify relay activity and to detect unusual DHCP query patterns that might indicate clients without valid DHCP configuration.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.14.2.11.21 snmpwalk -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmRelayMCPktInCnt
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.14.2.11.21.1 snmpget -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmRelayMCPktInCnt.1
