hh3cDhcpSnoopClientMacAddress
Module: HH3C-DHCPSNOOP-MIB
OID (symbolic): HH3C-DHCPSNOOP-MIB::hh3cDhcpSnoopClientMacAddress
OID (numeric): 1.3.6.1.4.1.25506.2.36.1.2.1.3
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: DHCP clients' MAC addresses collected by DHCP snooping.
What is hh3cDhcpSnoopClientMacAddress?
This read-only value reports the MAC address of a DHCP client that DHCP Snooping observed and recorded, indexed by that client's IP address. Admins use this to see which physical device, by MAC, is bound to a given leased IP, which is essential when investigating DHCP spoofing or tracking down a rogue device. For example, a row indexed on IP 192.168.1.50 might show hh3cDhcpSnoopClientMacAddress as 00:11:22:33:44:55, the MAC that leased that address.
