•
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 16.
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 23.
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” .
Connecting to Fabric OS using Telnet
1. Connect through a serial port to the switch that is appropriate for your fabric:
•
If Virtual Fabrics is enabled, log in using an admin account assigned the chassis-role
permission.
•
If Virtual Fabrics is not enabled, log in using an account assigned to the admin role.
2. Verify the switch’s network interface is configured and that it is connected to the IP network
through the RJ-45 Ethernet port.
