Version Description
6.1.1.0 Introduced on the E-Series.
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.
linecard portmode
Split a single 40G port into four 10G ports on the switch.
