9Telnet and SSH connectionsTelnet and SSH connectionsThe first time you log on to the console port, you must use a serial connection in order to assign anIP address to the port. Once an IP address is assigned, you can access the CLI through a localTelnet, SSH, or SNMP connection through the management port. When accessing the CLI throughTelnet, you maybe prompted for a password. By default, the password required is the one you enterfor general access at initial setup.NOTETelnet, SSH, Web, and SNMP servers are disabled by default, and can be enabled selectively.Telnet and SSH show commandsThis section describes the show command that displays Telnet information.show telnetSyntax: show telnetThis command shows you the number of open Telnet sessions at any given time, includinginformation about each session. Command output resembles the following example.Brocade# show telnetConsole connections:established3 days 17 hours 31 minutes 27 seconds in idleTelnet server status: EnabledTelnet connections (inbound):1 established, client ip address 10.53.1.65, privilege super-useryou are connecting to this session2 closed3 closed4 closed5 closedTelnet connections (outbound):6 established, server ip address 10.47.2.200, from Telnet session 14 seconds in idle7 closed8 closed9 closed10 closedSSH server status: EnabledSSH connections:1 closedTelnet and SSH debug commandsThis section describes the debug commands that generate information about Telnet and SSHconnections.debug ip telnetSyntax: [no] debug ip telnetThis command generates information about incoming Telnet connections, as shown in the followingexample.320 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
