EMM-E6 MIB Structure
A-2 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.
