TL1 Commands
This chapter provides the details of TL1 commands supported by the Cisco ONS 15216 EDFA2. This
chapter also maps various TL1 command parameters to their SNMP counterpart attributes in the ONS
15216 EDFA2 MIB (CERENT-15216-EDFA-MIB.mib).
9.1 Connection to the ONS 15216 EDFA2
The ONS 15216 EDFA2 system supports up to ten simultaneous Telnet connections via the Ethernet
LAN port. TL1 sessions are available on TCP/IP port 3082 for raw TL1 and/or port 3083 for TL1 over
Telnet. When connected, the ACT-USER command activates a session. (See the “8.3 Log In via LAN
Port Using Telnet (Optional)” section on page 8-3.)
9.2 Explanation of Command Parameters
TL1 messages are grouped into autonomous and non-autonomous types. Autonomous messages are
generated as a result of activity on the network elements such as alarms, thresholds, alerts and status
information. No request is required in order to receive autonomous messages. Non-autonomous
messages consist of a request command and a response from the ONS 15216 EDFA2. Autonomous
messages and non-autonomous commands use a common set of parameters. Some of the most common
parameters are defined in the following sections.
9.2.1 Source Identifier (sid) and Target Identifier (tid)
The source identifier (sid) or target identifier (tid) parameters uniquely identify an ONS 15216 EDFA2.
For the ONS 15216 EDFA2, sid and tid are the same. While the TL1 shell uses the sid/tid name in its
command line prompt, the ASH shell uses the host name. The sid/tid name is the same as the sysName
in the SNMP MIBs.
