• Details—Displays the details for the selected session. The parameters and values differ, depending
on the type of session.
• Logout—Ends the selected session.
• Ping—Sends an ICMP ping (Packet Internet Groper) packet to test network connectivity.
Specifically, the security appliance sends an ICMP Echo Request message to a selected host. If the
host is reachable, it returns an Echo Reply message, and the security appliance displays a Success
message with the name of the tested host, as well as the elapsed time between when the request was
sent and the response received. If the system is unreachable for any reason, (for example: host down,
ICMP not running on host, route not configured, intermediate router down, or network down or
congested), the security appliance displays an Error screen with the name of the tested host.
• Logout By—Selects a criterion to use to filter the sessions to be logged out. If you select any but
--All Sessions--, the box to the right of the Logout By list becomes active. If you selected the value
Protocol for Logout By, the box becomes a list, from which you can select a protocol type to use as
the logout filter. The default value of this list is IPSec. For all choices other than Protocol, you must
supply an appropriate value in this box.
• Logout Sessions—Ends all sessions that meet the specified Logout By criteria.
• Refresh—Updates the screen and its data. The date and time indicate when the screen was last
updated.
