Fabric OS command line interface 1 Parameter Stop bits Flow control Value 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 Connect to the Fabric OS through a Telnet or SSH connection or through 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 2. 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. See "DHCP activation" on page 8 for more details. Rules for Telnet connections The following rules should 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 root, 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, see "For details on Brocade MIB files, naming conventions, loading instructions, and information about using the Brocade SNMP agent, see the Fabric OS MIB Reference." on page 115 and "Managing User Accounts" on page 69. Connecting to Fabric OS using Telnet 1. Connect to the switch that is appropriate for your fabric: • If Virtual Fabrics is enabled, then log in using an admin account assigned the chassis-role permission. • If Virtual Fabrics is not enabled, then log in using an account assigned to the admin role.

Fabric OS command line interface
1
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
Connect to the Fabric OS through a Telnet or SSH connection or through 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 2.
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. See
“DHCP activation”
on page 8 for more details.
Rules for Telnet connections
The following rules should 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 root,
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, see
“For details on Brocade MIB files,
naming conventions, loading instructions, and information about using the Brocade SNMP
agent, see the Fabric OS MIB Reference.”
on page 115 and
“Managing User Accounts”
on
page 69.
Connecting to Fabric OS using Telnet
1.
Connect to the switch that is appropriate for your fabric:
If Virtual Fabrics is enabled, then log in using an admin account assigned the chassis-role
permission.
If Virtual Fabrics is not enabled, then log in using an account assigned to the admin role.
