3. Use the arrow keys to highlight the SAVE command.
4. Press ENTER. The Event Message Line at the top of the screen

5.16 SNMP COMMUNITY NAMES SCREEN
The SNMP Community Names screen enables 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 6H123-50 and 6H133-37. Access to the 6H123-50 and
6H133-37 is controlled by enacting any of three different levels of
security authorization (read-only, read-write, and super-user).
!
CAUTION
If the 6H133-37 is being bridged to an FDDI ring (for example,
via an HSIM-F6 installed in the 6H133-37) IP Fragmentation
should be enabled. If IP Fragmentation is disabled, all FDDI
frames that exceed the maximum Ethernet frame size will be
discarded.
NOTE
If the 6C105 has been assigned community names, it is not
necessary to assign community names to the individual
modules installed in the chassis unless the user wishes to limit
access to 6C105 chassis screens by assigning different
community names to the module. When this is done access is
limited to the screens specific to the module to which the
terminal is attached and the Local Management session begins
at the Module Menu screen. See
Section 5.13 .
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.
