Type Field Description
Operational Service interface is not
operational. Check connectivity
for proper service.
System functions reference specific interfaces for
connectivity. For proper operation, corresponding
system interfaces must be enabled and
operational.
Configuration RADIUS Failover is not
configured or there are not
enough serves for redundancy
It is a best practice to configure at least one pair of
RADIUS servers to support authentication
redundancy.
Configuration Bonded channels configured
with a dierent frequency than
the Management channel
Configure bonded channels with the same
frequency as the Management channel. When
channel width is larger than 20 MHz, use one 20
MHz sub-channel as a Management channel to
transmit beacons. When Management channel
frequency is configured dierently than other
channels, channel interference can occur and
throughput is reduced.
Configuration Default Route configured for
router on data interface
Configure the Default Route/Gateway with a next-
hop associated with a physical interface. Do not
point the Default Route to the Admin interface. A
best practice is to map the Default Route through
a topology on a data port for proper system
functionality. If necessary, configure the static
routes via the Admin port for administration level
access.
Configuration Hotspot WLANs with the
configured number of IDs in the
roaming consortium.
Configure authentication of mobile devices to the
members of a roaming consortium, or for a
particular service provider that has a roaming
consortium. Add the appropriate IEEE-assigned
Organizational Identifier (OI). Specify up to eight
identifiers unique to the organization that are part
of the MAC address.
The AP39xx access points continue to support
only two identifiers. For more information, see SP
Identification on page 234.
Operational Backup tunnel established to
Extreme Campus Controller
To improve resilience and reduce the outage
interval associated with a failover event in a high-
availability setup. Access points establish session
tunnels to both peers in a high-availability pair.
Operational AP acknowledgment message APs send an acknowledgment message for each
configuration update. A missing configuration
acknowledgment message from an AP can
indicate a connectivity issue.
Operational Communication between AP and
controller over port 13910 is
blocked by the firewall
For proper communication between the AP and
the controller, ensure that Port 13910 is open in the
firewall.
Note: When the AP is more than one hop away,
setting the default route via the Management port
can also block communication between an AP and
the controller.
