Parameter Description
Local Cache Lifetime (hrs) This parameter specifies the lifetime in hours for the cached access credential in
the local Survival Server. When the specified cache-lifetime expires, the cached
access credential is deleted from the switch.
Configured authentication servers are put into the out-of-service (OOS) state
when authentication requests time out. The wireless switch picks the next server
from the server group when the previous server times out or fails.
When there are no more servers available from the server group, the local
Survival Server processes the authentication request. When the client is
authenticated with the local Survival Server, the previously stored Key Reply
attributes are included in the RADIUS response.
The Cache Lifetime range is from 1 to 168 hours. The default is 24 hours.
CA Certificate Assigned for
Auth Survivability
Select the certificate to be used for client authentication.
WANHealth Check
Health-Check Select the health-check option to use ping-probes to measure WAN availability
and latency on selected uplinks. Based upon the results of this health-check
information, the switch can continue to use its primary uplink, or failover to a
backup link.
WAN Select the WAN tab to define ping probe settings for the health-check feature
Probe Mode
Click the Probe Mode drop-down list and select ping or udp to enable ip probes
of the selected type.
Probe Interval (sec)
The Probe Interval field specifies the probe interval, in seconds. The WAN
health-check feature sends the number of probes defined by the Packet Burst
per Probe parameter during each probe interval. To change the default interval
of 10 seconds, enter a new value into this field.
PacketBurst Per Probe
The Pocket Burst per Probe field specifies the number of probes to be sent
during the probe interval. To change the default value of 5 probes, enter a new
value into this field.
Probe Retries
The number of times the switch will attempt to resend a probe.
IP/FQDN of remote host IPaddress or Fully Qualified Domain Name (FQDN) of the remote host to which
the ping probes are sent.
Jitter Measurement Jitter is a variation in the delay of received packets, which can be worsened by
network congestion, improper queueing and configuration errors. The WAN
health-check feature measures jitter on the connection to the remote host by
sending and measuring packets at fixed intervals.
PBR Select the PBRtab to define ping probe settings for policy-based routing.
Probe Mode
Click the Probe Mode drop-down list and select ping to enable ip probes.
Probe Interval (sec)
The Probe Interval field specifies the probe interval, in seconds. The WAN
health-check feature sends the number of probes defined by the Packet Burst
per Probe parameter during each probe interval. To change the default interval
of 10 seconds, enter a new value into this field.
