4.2 SNMP and RMON Management

The Simple Network Management Protocol (SNMP) may be used to manage the IntraCore 3524. The SNMP agent supports database objects that are defined in the following management information bases (MIBs):

•MIB II (RFC 1213)

•Bridge MIB (RFC 1493)

•RMON (RFC 1757) 4 groups - Ethernet Statistics, Ethernet History, Alarm, and Events (See next section for details)

•Private Asanté 3524 MIB

Any SNMP-based network management application can be used to manage the switch. For information on management of switches, refer to your SNMP software manual. Also, see Chapter 6. SNMP Management for more information on SNMP protocol.

For details on console-based SNMP settings, see “SNMP Configuration” in Chapter 3.

RMON Management

Remote Network Monitoring (RMON) allows the network manager to gather data on the network’s traffic for future retrieval. RMON is an Internet Standard defined in RFC1757.

Using RMON, a network monitor (also called a probe) listens to traffic on the network and gathers statistics that may be retrieved later by a network management station using SNMP, as described in the previous section.

The four groups of RMON that are supported by the switch are described in Chapter 6. SNMP Management.

The IntraCore 3524 switches provide control of the RMON groups only through SNMP. For information on controlling RMON groups, please refer to the documentation for your SNMP management application.

Important! For any traps (alerts) to be sent, you must designate one or more devices as trap receivers. See “SNMP Configuration” in Chapter 3.

4.3.1 Duplicated IP Detection and Trap

The duplicated IP detection and duplicated IP trap security measures allow you to monitor the use of a single IP address by two stations.

If you enable duplicated IP detection, the switch starts monitoring the broadcast Address Resolution Protocol (ARP) traffic from all of its ports, to detect duplicated IP address conditions. When duplicate IP
