Fabric OS command line interface 2 • In a Windows environment enter the following parameters: TABLE 2 Terminal port parameters Parameter Value Bits per second Databits Parity Stop bits Flow control 9600 8 None 1 None • In a UNIX environment, enter the following string at the prompt: tip /dev/ttyb -9600 If ttyb is already in use, use ttya instead and enter the following string at the prompt: tip /dev/ttya -9600 Telnet or SSH sessions You can connect to the Fabric OS through a Telnet or SSH connection or by using a console session on the serial port. The switch must also be physically connected to the network. If the switch network interface is not configured or the switch has been disconnected from the network, use a console session on the serial port as described in "Console sessions using the serial port" on page 56. NOTE To automatically configure the network interface on a DHCP-enabled switch, plug the switch into the network and power it on. The DHCP client automatically gets the IP and gateway addresses from the DHCP server. The DHCP server must be on the same subnet as the switch. Refer to "DHCP activation" on page 66. Rules for Telnet connections The following rules must be observed when making Telnet connections to your switch: • Never change the IP address of the switch while two Telnet sessions are active; if you do, your next attempt to log in fails. To recover, gain access to the switch by one of these methods: - You can use Web Tools to perform a fast boot. When the switch comes up, the Telnet quota is cleared. (For instructions on performing a fast boot with Web Tools, see the Web Tools Administrator's Guide.) - If you have the required privileges, you can connect through the serial port, log in as admin, and use the killTelnet command to identify and kill the Telnet processes without disrupting the fabric. • For accounts with an admin role, Fabric OS limits the number of simultaneous Telnet sessions per switch to two. For more details on session limits, refer to Chapter 5, "Managing User Accounts". Fabric OS Administrator's Guide 57 53-1002745-02
