SSH. Enabled by default.
This setting does not control SSH access to individual device ports. (See Device Ports
- Settings (on page 160) for information on enabling SSH access to individual ports.)
Most system administrators enable SSH logins, which is the preferred method of
accessing the system.
Web SSH Enables or disables the ability to access the SLC command Iine interface or device
ports (connect direct) through the Web SSH window. Disabled by default.

specified number of minutes. Select Yes and enter a value of from 1 to 30 minutes.

If idle connection timeouts are enabled, this setting indicates the direction of data used
to determine if the connection has timed out. Select the type of data direction:

SSH Port Allows you to change the SSH login port to a different value in the range of 1 - 65535.
The default is 22. Use of ports other than 22 that are less than 1025 is not
recommended.

for the SLC unit. Disabled by default. Enabling this option will also disable MACs with

64@openssh.com).

individual ports.) You may want to keep this option disabled for security reasons.
