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.
