Telnet Or Ssh Sessions - HP SN3000B Administrator's Manual

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
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
activation"
Rules for Telnet connections

on page 23.
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
Accounts".
