The MTU size of an interface affects IP packet fragmentation and reassembly on the interface.
To make the MTU configuration take effect on an interface, you must re-enable the interface by using the
shutdown command and the undo shutdown command.
Examples
# Set the MTU size of HDLC link bundle interface 1 to 1430 bytes.

Usage guidelines

If you specify hdlc-bundle but not bundle-id, this command clears the statistics of all HDLC link bundle
interfaces.
