terms of ring management, a hard-coded address is considered globally
administered because all ring stations will use it by default. Each byte is
identified in bit order starting with the most significant bit.
Locally Administered
This field lets you locally administer, or assign, an FNB MAC address,
overriding the physical default address.
To assign a Locally Administered FNB MAC address:
1. Highlight the Locally Administered field (showing by default the
Physical FNB MAC address).
2. Type the desired address into the field and press Enter. The format for
this entry is 40-00-00-00-00-00, with values of 0 ranging from 0-9 and
A-Z for all but the first two values (use 40 for the first two values).
3. Highlight SAVE at the bottom of the screen and press Enter. The
“Saved” message will appear. The changes are saved to memory, and
will take effect immediately.
4.2 THE SNMP COMMUNITY NAMES SCREEN
This screen allows you to establish the SNMP Community Names (or
passwords) used for access privileges to the TRMM/TRMMIM. To access
the SNMP COMMUNITY NAMES screen (Figure 4-3) from the
DEVICE SETUP menu screen, highlight the SNMP COMMUNITY
NAMES option and press Enter.
Community names serve two purposes: they act as a password to Local
Management and they serve as a security means to control SNMP
management access to the TRMM/TRMMIM.
You control access to the TRMM/TRMMIM by establishing up to three
levels of security authorization (Read Only, Read-Write, and Super-user).
If you have Super-user access, you can change the existing passwords by
changing the community names.
NOTE: All community names assigned in the SNMP COMMUNITY
NAME screen are passwords to Local Management. Only the community name
assigned Super-user access is accorded full read/write privileges to Local
Management.
