Testing the SG810
If you suspect a problem with the SG810, test its operation and connection using
the CLI. Use the
ping
and
traceroute
commands to test the network connection.
From enable mode, use
test http get
command to retrieve an object or
test
http loopback
command to run a loopback test to verify that the device is
operational. Refer to Blue Coat ProxySG Command Line Interface Reference for
information on these commands.
CLI Session Times Out
An SSH session to the CLI remains open as long as there is activity. If you leave
the session idle, the connection eventually times out and you will have to
reconnect. The default timeout is five minutes. You can set the timeout by using
the
line-vty
command in configure mode, as follows:
SGOS#(config)line-vty
SGOS#(config line-vty) timeout minutes
SGOS#(config line-vty) exit
CLI Limited to 16 Sessions
The CLI is limited to 16 active sessions (and one serial console session). If you try
to connect a 17th session, you receive a message saying that no more sessions are
available. To connect, you will have to wait for one of the active sessions to close.
Cannot Access the Serial Console
If you have connected a serial cable to the SG810 but you cannot open the serial
console, do the following:
• Check cable connections.
• Check configuration information at the terminal emulator for the correct
settings (see
“Initial Configuration Using a Serial Console” on page 34 for
information).
• Verify that the serial cable is a Null Modem type cable. The cable pin outs can
be found at
http://www.bluecoat.com/support/self-service/1/pinouts.html
• Use a different cable.
