The VLANS tab
for a selected device provides status information on the AP tunnel between the AP
and the appliance, both for single deployments and for an availability pair. For
devices configured with a VxLAN topology, it displays status information for the
VxLAN tunnel.
Note
Supported on Wi-Fi 6 AP models.
To view tunnel status information:
Go to Monitor > Devices > Access
Points.
Select an AP.
Select VLANS.
AP Tunnel
Note
This information does not pertain to the GRE
Point-to-Point Tunnel feature, which supports tunneling traffic between
access points without traversing the controller.
The following information displays for the AP tunnel between the selected AP and the
appliance:
IP Address
The IP address of the
appliance. In an availability pair, the primary appliance is listed
first.
Status
Operational status of the
AP Tunnel. Valid values are: Normal and Failed.
Type
Indicates the controller in an availability pair. Valid values are:
Active or Backup, referring to the Primary Appliance or Backup
Appliance, respectively.
Configured MTU
The Maximum Transmission
Unit (MTU) setting for the AP. With Jumbo Frames, this can be up to 1800
bytes. AP MTU is configured in the device group configuration Profile or
as an AP override.
Configured MTU Tunnel Status
The status of the MTU
tunnel between the selected AP and the appliance. Valid values are
Normal and Failed. When the Configured
MTU value is set to 1800 and this tunnel fails, it
indicates that a router in the chain between the AP and the appliance
does not support the Jumbo Frames value of 1800 bytes. The MTU values
for all devices in the path from AP to appliance must match.
Path MTU Learned by AP
When a router does not
support the MTU setting of 1800 bytes, it sends a message back to the AP
indicating the MTU value it can support. If necessary, reconfigure the
Configured
MTU value for this AP to match the router setting. The
MTU values for all devices in the path from AP to appliance must
match.
Internal Management Tunnel
The status of an internal
tunnel within ExtremeCloud IQ
Controller. Valid values are Normal, Failed, and MTU
Failed. If this tunnel fails, contact Extreme Networks Support.
VLANS
The following information displays for configured VLANS:
Name
Topology Name
Mode
Topology type. Valid
values are:
Bridged@AP
Bridged@AC
Fabric
Attach
VxLAN
Tagged
A check mark indicates
that VLAN is tagged. If you have more than one VLAN on a port, enable tagging to identify
to which VLAN the traffic belongs. Ensure that the tagged vs. untagged state is consistent
with the switch port configuration. Fabric Attach topologies are always tagged.
VLAN ID
Identifies the VLAN.
I-SID
For Fabric
Attach. A unique VLAN identifier and a unique I-SID (service identifier). The
I-SID range is (0-15999999).
Certificates
Indicates that a
certificate has been applied to the AP.
Remote VTEP
For VxLAN.
The IP address of the tunnel End-Point is referred to as a
VxLAN Tunnel Endpoint (or VTEP). The VTEP is the IP address of the network switch. Network
switches that act as a VTEP are referred to as VxLAN gateways. There can only be one VTEP
per VxLAN topology.
VNI
For VxLAN.
VxLAN Network Identifier. The VNI is a 24-bit identifier. It can be used
in more than one VxLAN topology.
Tunnel Status
For VxLAN.
Status of the VxLAN tunnel. Valid values are Normal, Failed, and MTU
Failed. MTU Failed indicates that the VxLAN MTU setting of 1550 bytes is
not supported on another device in the chain between the AP and the
appliance. The MTU values for all devices in the path from AP to
appliance must match.
