6.7 Configure the SNMP Manager
From the SNMP Card Config menu, select item "2", Manager Config. Manager configuration
is required to tell the agent (the SNMP card) who has authority to access the SNMP via "Get"
commands (read) or "Set" commands (write) and where to send "trap" messages (unsolicited
messages that are usually generated by alarms in the Fiber Multiplexer).
LOCAL <<< Manager Config >>>
1. Access IP #1 [172. 24. 1.126] [Community #1] [Trap]
2. Access IP #2 [192.168. 0. 15] [Community #2] [Trap]
3. Access IP #3 [192.168. 0.125] [Community #2]
4. Access IP #4 [192.168. 0. 53] [Community #2]
5. Community String #1 (R/W) [secret]
6. Community String #2 (Read) [public]
Please select the item or <ESC> to previous menu.
The manager configuration has the ability to setup access for up to four (4) different
management workstations. The community strings act like passwords in dealing with the device via
SNMP protocol. By changing the community strings (numbered 1 & 2) for read / write ('secret' in
this case) and read only ('public') access, and assigning a community string to an access IP, an
administrator can control access to the Fiber Multiplexer.
Note that in the above example, the management workstation with IP address 172.24.1.126
and using the community string 'secret', has full read and write access and receives traps. The
management station at 192.168.0.15 has read only privileges when using the community string
'public' and can also receive trap messages. The other two stations at Access IP 3&4 have read only
access and do not receive any trap messages. After all settings have been made, <ESC> to the
SNMP Card Config menu and do "Save and Restart".
6.8 Save and Restart SNMP

CAUTION: It is imperative that power not be interrupted while the SNMP card is saving the
configuration to flash memory. Failure of power may result in scrambled flash contents and an
SNMP card in an un-usable state.
