Performance Management on Virtual Services Platform 4000 Series Version 5.1.2

Dynamic network applications
The remote access services supported on Virtual Services Platform 4000, for example the File
Transfer Protocol (FTP), Trivial FTP (TFTP), rlogin, and Telnet, use daemons. These remote access
daemons are not enabled by default to enhance security.
After you disable a daemon flag, all existing connections abruptly terminate, and the daemon
remains idle (accepts no connection requests).
Use the following dynamic network applications to manage remote access services:
• Access policies
• Port lock
• ACLI access
• SNMP community strings
• Web management interface access
For more information about how to enable remote access services, see Quick Start for Avaya Virtual
Services Platform 4000 Series, NN46251-102.
For more information about how to access policies, lock a port, access the ACLI, and configure
SNMP community strings, see Security for Avaya Virtual Services Platform 4000 Series,
NN46251-601.
For more information about how to access the Web management interface, see .
Digital diagnostic monitoring
Use Digital Diagnostic Monitoring (DDM) to monitor laser operating characteristics such as
temperature, voltage, current, and power. This feature works at any time during active laser
operation without affecting data traffic.
There are three optical transceivers that support DDM:
• Small Form Factor Pluggable (SFP) transceivers
• 10 Gigabit Small Form Factor Pluggable plus (SFP+)
• Quad Small Form Factor Pluggable plus (QSFP+)
Important:
The Avaya VSP 4000 does not support QSFP+ transceivers because the VSP 4000 devices do
not have any QSFP+ ports.
Digital Diagnostic Interface (DDI) is an interface that supports DDM. These devices provide real-
time monitoring of individual DDI SFPs, SFP+s and QSFP+s on a variety of Avaya products. The
DDM software provides warnings or alarms after the temperature, voltage, laser bias current,
transmitter power or receiver power fall outside of vendor-specified thresholds during initialization.
