A Few Words about MIB Components
and Community Names
As you might expect, the Solstice Enterprise Manager SNMP
Browser, which provides access to device MIB data, requires that you
supply the correct SNMP Community Name when accessing a
deviceÕs MIB information. For older Cabletron devices, whose MIB
information is contained in a single Òcomponent,Ó any valid
community name entered in these lines will provide complete access
to the deviceÕs MIB data.
However, the MIB information for newer Cabletron devices Ñ such
as the EMME, the TRMM-4, or any SmartSwitch device Ñ is
organized into multiple components. In the original versions of these
devices, each MIB component is protected by its own set of
user-conÞgurable Read Only, Read/Write, and SuperUser
community names. These names determine the level of access (read
only, read/write, or superuser) that will be granted to the
information controlled by each component. Newer versions of
devices with this component-based MIB architecture have been
simpliÞed somewhat; these devices support a single, global set of
community names, but small modiÞcations are still added
automatically to accommodate multiple instances of the same MIB
component (as occurs in multi-channel Ethernet repeaters or
multi-ring Token Ring devices).
For these devices, if you want to retrieve information from or write
information to a MIB component, you must supply the speciÞc
community name assigned to that component, including any
automatic modiÞcations that have been added.
You can display information about all of a deviceÕs MIB components,
including the community names, by using the SPMA Community
Names tool; see the Community Names chapter in the SPMA Tools
Guide
for details.
