Field Description
Recheck Interval Specifies the time interval between SRS rule rechecks
made by the TunnelGuard applet on the client machine.
Accepts an integer that indicates the time interval in
seconds (
s), minutes (m), or hours (h). The valid range is
60s (1m) to 86400s (24h). The default is 15m (15 minutes).
If a recheck fails, the Nortel SNAS 4050 terminates the
session and evicts the client from the portal.
Action on Failure Specifies the action to be performed if the client fails the
TunnelGuard SRS rule check. The options are:
• Restricted — the session remains intact, but access is
restricted in accordance with the rights specified in the
access rules for the group
• Tear Down — the SSL session is torn down
Heart Beat Interval Specifies the time interval between checks for client
activity.
Accepts an integer that indicates the time interval in
seconds (
s), minutes (m), or hours (h). The valid range is
60s (1m) to 86400s (24h). The default is 1m (1 minute).
Heart Beat Retry Count Specifies the number of times the Nortel SNAS 4050 will
repeat the check for client activity when no heartbeat is
detected.
Acceptable range is an integer from 1–65535. The default
is 3.
If no heartbeat is detected after the specified number of
retries (the inactivity interval), the Nortel SNAS 4050
terminates the session.
Status-quo Mode Specifies whether the Nortel SNAS 4050 domain operates
in status-quo mode. Status-quo mode determines the
behavior of the Nortel SNAS 4050 if no client activity is
detected after the inactivity interval.
If selected (status-quo on), then the client session
continues indefinitely.
If not selected (status-quo off), the Nortel SNAS 4050
terminates the session immediately.
The default is status-quo off (not selected).
