Chapter 7.1 - Port Usage
netLD uses multiple network ports for its various functions. The ports used by netLD are listed below. If communications with netLD will travers a firewall, configure the firewall policy based upon the protocols that you use.

(*1) The appropriate configuration depends on which models of devices are in use. For example,
- Adapter for IOS: CLI (Telnet, SSH)only, or both CLI and TFTP.
- Adapter for Alaxala: CLI (Telnet, SSH), FTP or SNMP.
(*2) Configured CLI protocols are used.
