Introduction Telnet Session The CLI can only be used through a Telnet client session in an out-of-band management environment, using the Ethernet port in a Director or Edge Switch. Although the primary use of the CLI is in host-based scripting environments, the CLI commands can also be entered directly at a command line. Any hardware platform that supports the Telnet client software can be used. NOTE: If you have the HAFM application, use the Configure option in the software to enable Telnet access before attempting to establish a Telnet client session. You can also enable Telnet access by using the Configure option of the Embedded Web Server (EWS). Telnet access is enabled by default. Any changes to the enabled state of the Telnet server are retained through system resets and power cycles. Ethernet Connection Loss If the Ethernet cable is disconnected from a Director or Edge Switch during a Telnet session, one of three scenarios is possible: • Replace the Ethernet cable before the client connection times out, and the Telnet session will continue. • Wait 15 minutes for the client connection times out; then replace the Ethernet cable and restart the connection. • If the client connection has already timed out, replace the Ethernet cable. Open an EWS or HAFM application window. Toggle the enabled state of the CLI, thereby clearing the client connection. Restart the client connection. Once the client connection is reestablished, verify your configuration's completeness and accuracy. 1-16 CLI reference guide for directors and edge switches
