A tunnel profile is essential for managing
and optimizing the behavior of tunnels between Access Points (APs) and the RUCKUS Edge device.
You can apply the same Tunnel Profile to multiple venues, but each venue can have only one
Tunnel Profile applied.
APs use tunnel keepalive request
messages to verify the reachability of the RUCKUS Edge
device before establishing AP data tunnel and broadcasting WLANs enabled with an
SD-LAN service. Once the tunnel is established, APs continue to send periodic
keepalive request messages to monitor the reachability of the Edge device. If the AP
does not receive responses for the maximum number of consecutive keepalive requests,
it assumes the Edge is unreachable, brings down the tunnel, and stops broadcasting
the WLANs. The AP continues to send periodic keepalive requests and will
re-establish the tunnel and resume broadcasting WLANs upon receiving responses.
Complete the following steps to create
a Tunnel Profile:
From the navigation bar, select
Network
Control > Policies &
Profiles.
The Policies
& Profiles page is displayed.
In the Policies &
Profiles page, click Tunnel Profile tile and
click the Add Tunnel Profile. Alternatively, in the
Policies & Profiles page, click the Add Policy or
Profile then select the Tunnel Profile
tile, and click Next.
The Add Tunnel
Profile page is displayed.Add Tunnel Profile
Page
Complete the following
fields:
Profile
Name: Enter the name for the tunnel policy.
Network Segmentation
Type: The VLAN to VNI
map option is selected by default. The SD-LAN
service maps the VLAN ID to the VNI for tunneling. The
VNI option is used for the PIN feature.
Gateway Path MTU Mode: Select one of following
options:
Auto
Manual: Enter the value in bytes (allowed
values are 576 to 1450). The value must be lesser than the
Ethernet MTU on the AP.
Note: Check the
Ethernet MTU on the AP; Tunnel MTU gets applied only if it
is less than the Ethernet MTU.
Path MTU Request
Timeout: The maximum wait time for a response to a path
MTU request. Range: 10 milliseconds to 10 seconds; default is 2
seconds.
Path MTU Request
Retries: The maximum number of Path MTU requests sent to test
one MTU value. Range: 3 through 64; default is 5 retries.
Force
Fragmentation: When enabled, the AP or Edge device will
automatically fragment packets, ignoring the Don't Fragment (DF) bit in
the IP header of the packets. Forced packet fragmentation can reduce
congestion and improve network throughout, but it may lead to fragment
loss, packet reassembly issues, and memory exhaustion. This option is
disabled by default. Toggle the switch to ON to
enable.
Tunnel Idle
Timeout: The amount of time a tunnel is allowed to remain
active without any traffic. Select Minutes,
Days, or Weeks
from the drop-down list and then enter the duration or use the up/down
arrows to set the value. Range: 5 through 10080 minutes, 1 through 7
days, or 1 week; default is 20 minutes.
Tunnel Keep Alive Interval: Defines the interval
between two consecutive keepalive request messages. Range: 1 through 5
seconds, with a default value of 2 seconds.
Tunnel Keep Alive Retries: Defines the maximum
number of consecutive keepalive requests that can fail before the AP
determines the Edge device is unreachable. Range: 3 through 10 retries,
with a default value of 5.
Click Add.
The Tunnel Profile is created
and is displayed in the Tunnel Profile page.
