SNMP COMMUNITY NAMES SCREEN
The SNMP Community Names menu item allows the user to set
Local/Remote Management community names. Community names act as
passwords to Local/Remote Management and are agents of security
access to the DLEHF-MA. Access to the DLEHF-MA is controlled by
enacting any of three different levels of security authorization (read-only,
read-write, and super-user).
To access the SNMP Community Names screen from the Module
Configuration Menu screen, use the arrow keys to highlight the SNMP
COMMUNITY NAMES menu item and press ENTER. The SNMP
Community Names screen, Figure 5-20, displays.

If the DLEHF-MA is being bridged to an FDDI ring IP
Fragmentation should be enabled. If IP Fragmentation is
disabled, all FDDI frames that exceed the maximum Ethernet
frame size will be discarded.
If the DLM6C-AA has been assigned community names, it is
not necessary to assign community names to the individual
modules installed in the chassis unless you wish to limit access
to DLM6C-AA chassis screens by assigning different
community names to the module. When this is done, access is
limited to the screens specific to the module the terminal is
attached to and the Local Management session will begin at
the Module Menu screen.
Super-user access gives the user full management privileges,
allows existing passwords to be changed, and all modifiable
MIB objects for the Cabletron Container MIB and Internet
MIB-II to be accessed.
