Cancelling an outbound Telnet session
If you want to cancel a Telnet session from the console to a remote Telnet server (for example, if the
connection is frozen), you can terminate the Telnet session by doing the following.
1. At the console, press Ctrl+^ (Ctrl+Shift-6).
2. Press the X key to terminate the Telnet session.
Pressing Ctrl+^ twice in a row causes a single Ctrl+^ character to be sent to the Telnet server. After
you press Ctrl+^, pressing any key other than X or Ctrl+^ returns you to the Telnet session.
Specifying an SNTP server
The Brocade device can be configured as a Simple Network Time Protocol (SNTP) client. You can
configure the Brocade device to consult up to three SNTP servers for the current system time and
date. The first server configured will be used unless it becomes unreachable, in which case the
Brocade device will attempt to synchronize with the other SNTP servers (if any) in the order in which
they were configured.
NOTE
Brocade devices do not retain time and date information across power cycles. Unless you want to
reconfigure the system time counter each time the system is reset, Brocade recommends that you
use the SNTP feature as described below.
To identify an SNTP server with IP address 10.99.8.95 to act as the clock reference for a Brocade
device, enter the following.
Brocade(config)# sntp server 10.99.8.95
Syntax: [no] sntp server {
authentication-key <key-ID> <key-string>]
The
– 4. The default is 4. The SNTP version is automatically set to 4, unless a different SNTP version is
specified in the device startup configuration. You can configure up to three SNTP servers by
entering three separate sntp server commands.
The order in which the SNTP servers are configured is the order in which they are consulted. The
server that was configured first is the first server consulted after the poll cycle; the next server will
be consulted only if a positive ACK is not received from the first one.
To specify an IPv6 address for the SNTP server, use the ipv6 option.
