SNMP Overview
Command Syntax Using the SNMP Agent
Although Cisco has its own separate SNMP manager (Cisco Transport Manager [CTM]),
communication with the ONS 15216 EDFA2 is also possible using the built-in SNMP manager, its agent,
and the MIB. (See Figure 5-1.)
The commands and command syntax displayed in this manual are the result of using the built-in ONS
15216 EDFA2 SNMP manager included with the CLI card.
Commands can be issued via Telnet over a LAN or directly through the RS-232 port on the module. (See
Chapter 3, “Installation”.) After setting up a connection to the module and entering a password and user
name, the following prompt appears:
hostname:ONS15216 EDFA2>
To communicate with the module using SNMP, the command must begin with “snmp”.
Note To view a list of possible SNMP operations, enter “snmp” followed by a space and press the Tab key.

Table 5-1 SNMP Operation Types
Operation Description
get-request Retrieves a value from a specific variable.
get-next-request Retrieves the value following the named variable; this operation is often used
to retrieve variables in a Table. With this operation, an SNMP agent does not
need to know the exact variable name. The SNMP manager searches
sequentially to find the needed variable in the MIB.
get-response The reply to a get-request, get-next-request, get-bulk-request, or set-request
sent by an NMS.
get-bulk-request Similar to a get-next-request, but this operation fills the get-response with up
to the max-repetition number of get-next interactions.
trap An unsolicited message sent by an SNMP agent to an SNMP manager
indicating that an event has occurred.
set-request Sets a value of a specific variable.
