Command History
Version 9.0(1.3) Introduced on the S5000.
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.
