EMM-E6 MIB Structure

MIB Components

The EMM-E6 MIB components are described below. Note, however, that at any given time the component list displayed by your EMM-E6 may not include some of the components described below, since the EMM-E6 has the ability to alter the components which make up its MIB in response to changes in the chassis. For example, if you are using only two of the EMM-E6’s three internal repeating channels, you will see only two Repeater components listed; if, at any time, you add the third channel, the necessary MIB component will automatically appear in the chCompTable. Similarly, if you have an unmanageable MIM (such as a Token Ring MIM) installed in your EMM-E6-controlled hub, you will see the NoMgmtMIMs MIB component listed; this component will not appear if the EMM-E6 can manage all of the MIMs installed in your hub. To see which MIB components are currently being used in your EMM-E6, bring up the Community Names application, or use any SNMP Get operation that will allow you to view the contents of the chCompTable.

The EMM-E6 MIB consists of the following components:

Chassis MGR

The Chassis MGR MIB component contains most of the basic information about the EMM-E6, the chassis it is controlling, and the other modules installed in that chassis, including: chassis type, backplane type, number of slots, which module types and names are installed in which slots, the EMM-E6’s MIB component information (in the chCompTable), device and module names, hardware revision numbers, MAC and IP addresses, the current time and date, and information related to redundancy, alarms, connected uninterruptable power supplies, and TFTP download. The system, interfaces, at, ip, icmp, udp, and snmp groups from MIB-II are also included. The community names assigned to this MIB component provide the gateway that all SPMA applications use to access all information in the other components, even if those components have different community names; the Chassis MGR community names are the same as those assigned via Local Management.

LIM

The EMM-E6 LIM, or Local Management, component contains the objects that provide out-of-band management via the Console port on the EMM-E6’s front panel. No objects from this component are used for remote management; however, you can access the EMM-E6’s Local Management via the SPMA Telnet tool, described in the SPMA Tools Guide.
