efm-oam keepalive-interval
Argument Description
<
interval>
Specifies the aging interval in the range <1-10>.
Example
device-name
(cfg protocol)#
efm-oam keepalive-interval 3
Setting the Hello Interval
The
efm-oam hello-interval
command, in Protocol Configuration mode, sets the time interval
between two PDUs in milliseconds. This mechanism is used to inform the neighboring device that
the local device is operative. When the local device receives no PDU within the defined keep-alive
interval, the neighboring device is considered inoperative. The
no
form the command resets the
Hello Interval to its default.
By default, the Hello Interval is 1000 milliseconds.
NOTE
The standard hello interval is 1 second, however in order to reduce overload in
some cases – it is possible to set the range to 5 seconds even though it violates the
standard.
NOTE
The keepalive-interval must be 2.0 times bigger than the hello-interval.
