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 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 { <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.

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.
