Description: This value is the number of messages received by the DHCP server since the last reset which were directed to other servers.
What is ctDhcpOtherServers?
ctDhcpOtherServers is a read-only counter of the number of messages received by this DHCP server since its last reset that were actually directed to other DHCP servers on the network. An admin uses this to detect the presence of a competing DHCP server on the same segment, since clients broadcasting to multiple servers is a sign of an unintended rogue DHCP server. For example, a nonzero and climbing ctDhcpOtherServers count would prompt the admin to search the segment for an unauthorized second DHCP server that shouldn't be there.
