Auto-IP
Auto-IP is a protocol that will automatically assign an IP address from a reserved pool of standard
Auto-IP addresses to the computer on which it is installed. ConnectPort LTS is set to obtain its IP
address automatically from a DHCP server. But if the DHCP server is unavailable or nonexistent,
Auto-IP will assign the device an IP address. For further details, see "IP address assignment
alternatives.”
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring network
devices. SNMP architecture enables a network administrator to manage nodes--servers,
workstations, routers, switches, hubs, etc.--on an IP network; manage network performance, find
and solve network problems, and plan for network growth. ConnectPort LTS products support
SNMP Versions 1, 2, and 3. For more information on SNMP as a device-management interface, see
"Simple Network Management Protocol (SNMP).”
