Configure the maximum frame size that can be transported across the URWB network using CLI commands.

Configure the maximum transmission unit (MTU) settings to control the maximum frame size that can be transported across the URWB network.

This setting must be configured on every access point in the URWB network to ensure consistent frame size handling across the entire network.

Procedure

	1.	Configure the MTU value for wired interfaces. Example: `Device# configure wired mtu <1530-1600> Unsigned integer set wired mtu` Example: `Device# configure wired mtu 1600`
	2.	Verify the MTU value for wired interfaces. Example: `Device# show wired mtu Configured MTU: 1600`
