SNMP protocol

Remote system monitoring is available using Simple Network Management Protocol (SNMP). An agent resides in the iPBridge which takes information from the iPBridge and translates it into a form compatible with SNMP. If certain conditions arise, the agent sends asynchronous notifications (traps) to a client.

Refer to Diagnostic commands on page 43 for detailed information on the commands which regulate SNMP on the iPBridge.

Contact your network administrator for the MIB software and appropriate MIB file for your iPBridge. Use the SNMP page of the ExpressNAV interface to enable traps or extended traps.

Set up a VLAN: Virtual Local Area Network

A Virtual LAN (VLAN) is a group of devices on different physical LANs which can commu- nicate with each other as if they were all in the same physical LAN. This creates a network that is independent of physical location, allows grouping of users into logical workgroups, increases efficient use of resources, and adds security options by allowing some users into the LAN and keeping other users out.

Use the VLAN command to create up to eight Virtual LAN IDs for each Ethernet data port. Each VLAN ID is assigned a VLAN name of up to 64 characters. If no VLAN Id exists for a data port, VLAN is disabled for that port. For details on the command, refer to Ethernet commands on page 49.
