EMM-E6 MIB Structure

Distributed LAN Monitor

The Distributed LAN Monitor, or DLM, MIB component is a proprietary feature that allows you to delegate a management station’s polling responsibilities to one or more strategically placed “smart hub” devices — like an EMM-E6 — on your network, reducing overall network SNMP traffic by reducing the number of devices reporting directly to your management station.

MIB Navigator

The MIB Navigator component provides a command set from which you can configure and manage your EMM-E6 by telnetting directly into the device and viewing and modifying the objects in the device’s MIB. The MIB Navigator is accessible through SPMA via the Telnet application; see the SPMA Tools Guide and/or your EMM-E6 hardware manual for more information.

RMON Default

The RMON, or Remote Network Monitoring, Default MIB component contains the statistics, history, alarm, and event groups from the RMON MIB (RFC 1271). This component is shipped in an inactive state, and can be activated and deactivated as necessary.

RMON Host

The RMON Host MIB component contains the host, hostTopN, and matrix groups from the RMON MIB. These groups are contained in a separate MIB component because they require a large proportion of a device’s RAM and CPU resources; this component is shipped in an inactive state, and can be activated and deactivated as necessary.

Transparent Bridge

The Transparent Bridge MIB component controls all of the EMM-E6’s bridging functions, including bridge port description and status, bridging statistics (frames forwarded, frames blocked, etc.), and bridge configuration information.

NoMgmtMIMs

If you have an unmanageable MIM (such as a token ring MIM) installed in your EMM-E6-controlled hub, the NoMgmtMIMs MIB component provides the EMM- E6 with enough information so that the MIM can be represented in the Hub View with its type and the designation “No Mgt” displayed.

Orphan MIMs

The Orphan MIMs MIB component provides minimal management for any repeater MIMs (RMIMs) installed in the EMM-E6-controlled hub that are configured for operation in stand-alone (isolated) mode.
