Keepalive-Icmp - Avaya G250 Reference

CLI Commands

keepalive-icmp

Use the keepalive-icmp command to enable the ICMP keepalive mechanism on an
interface. ICMP keepalive is a mechanism that reports on the status of an IP address and its
next hop. The destination interface is only declared to be alive if the next hop is also reachable.
This feature is critical for mechanisms such as policy-based routing that must guarantee service
on a particular path.
Use the no form of the command to disable extended keepalive on the interface.
Note:
You cannot configure both keepalive-icmp and ip address dhcp (DHCP
Note:
Client) on the WAN Fast Ethernet interface.
