Specifying an SNTP server
The user remained in the Privileged EXEC mode until 5:59 PM and 22 seconds. (The user could
have used the CONFIG modes as well. Once you access the Privileged EXEC level, no further
authentication is required to access the CONFIG levels.) At 6:01 PM and 11 seconds, the user
ended the CLI session.
Disabling the Syslog messages and traps
Logging of CLI access is enabled by default. If you want to disable the logging, enter the following
commands.
Brocade(config)# no logging enable user-login
Brocade(config)# write memory
Brocade(config)# end
Brocade# reload
Syntax: [no] logging enable user-login
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 208.99.8.95 to act as the clock reference for a Brocade
device, enter the following.
Brocade(config)# sntp server 208.99.8.95
Syntax: [no] sntp server { <ip-address> | <hostname> | ipv6 <ipv6-address> } [<sntp-version>] [
authentication-key <key-ID> <key-string>]
The <sntp-version> parameter specifies the SNTP version the server is running and can be from 1
– 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.
