What is hpicfDhcpSnoopCSBadReleases?
This counts DHCPRELEASE or DHCPDECLINE packets that were discarded because they arrived on a different port than the one the corresponding address was originally leased through. Admins use a rising count as a signal of possible MAC/port spoofing, since a legitimate client should release its lease from the same port it obtained it on.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.5.1.34.1.2.1.4 snmpwalk -v2c -c public <target> HP-ICF-DHCP-SNOOP-MIB::hpicfDhcpSnoopCSBadReleases
