keepalive <seconds>
Use the keepalive command to enable the transmission of keepalive packets on the interface and specify
the time interval in seconds between transmitted packets.
Syntax Description
<seconds> Defines the time interval (in seconds) between transmitted keepalive packets
(valid range: 0 to 32,767 seconds).
Default Values
By default, the time interval between transmitted keepalive packets is 10 seconds.
Command Modes
(config-interface)# Interface Configuration Mode
Valid interfaces include: Ethernet (eth 0/1), virtual PPP interfaces (ppp 1), virtual
HDLC interfaces (hdlc 1), virtual Frame Relay sub-interfaces (fr 1.20), tunnel
interfaces (tunnel 1), and VLAN interface (vlan 1).
Functional Notes
If three keepalive packets are sent to an interface with no response, the interface is considered down. To
detect interface failures quickly, specify a smaller keepalive time.
Usage Examples
The following example specifies a keepalive time of 5 seconds on the HDLC interface:
(config)#interface hdlc 1
(config-hdlc 1)#keepalive 5
