cDhcpv4ServerIfLeaseLimitExceeded
Module: CISCO-IETF-DHCP-SERVER-EXT-MIB
OID (symbolic): CISCO-IETF-DHCP-SERVER-EXT-MIB::cDhcpv4ServerIfLeaseLimitExceeded
OID (numeric): 1.3.6.1.4.1.9.10.122.0.2.0.1
Node type: NOTIFICATION-TYPE

Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CISCO-IETF-DHCP-SERVER-EXT-MIB::cDhcpv4ServerIfLeaseLimitExceeded snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.10.122.0.2.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:60539->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (245103227) 28 days, 8:50:32.27 SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-IETF-DHCP-SERVER-EXT-MIB::cDhcpv4ServerIfLeaseLimitExceeded
