Configuring and viewing the Tunnel Path MTU

In prior releases of the WLAN 8100, the Tunnel Path Maximum Transmission Unit (MTU) was
fixed at 1492 bytes for tunneling traffic between controllers and APs, and amongst controllers.
From release 2.1 onwards, you can configure the path MTU in the system in the range 1250
to 2372 bytes. This allows supporting tunnels over VPNs that may have MTUs lower than 1492
bytes.
Access points always receive the tunnel-path MTU configuration from its managing
controller.
Note:
Tunnel Path MTU configuration is supported only in Overlay deployments.
The following sections describe configuration of the Tunnel Path MTU using the Avaya CLI.
CLI reference:
WC8180(config-wireless)#tunnel-path-mtu ?
<1250-2372>
Procedure
1. Enter the wireless configuration mode of the CLI. Use the following commands:
2. Use the following command to set the Tunnel Path MTU to a value different from

WC8180(config-wireless)#tunnel-path-mtu 1250
Note:
The default value of the Tunnel Path MTU for the WC 8180 controller is 1492
bytes. The range is 1250 –2372 bytes.
Note:
It is recommended that all controllers in the domain are set with an identical
tunnel-path MTU configuration.
