History
Version 9.4(0.0)
Supported on the FN I/O aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Usage
Information
When you configure keepalive, the system sends a self-addressed packet out of
the configured interface to verify that the far end of a WAN link is up. When you
configure no keepalive, the system does not send keepalive packets and so the
local end of a WAN link remains up even if the remote end is down.
mtu
Set the link maximum transmission unit (MTU) (frame size) for an Ethernet interface.
Syntax
mtu value
To return to the default MTU value, use the no mtu command.
Parameters
value
Enter a maximum frame size in bytes. The range is from 594
to 9252. MXL Switch Range is from 594 to 12000. The
default is 1554.
