Mfr Timer Hello - H3C MSR810 Command Reference Manual

Usage guidelines
A bundle link maintains link status by periodically sending hello messages to its peer end. If the
bundle link sends a hello message but does not receive a hello acknowledgement, it will resend the
hello message. If the bundle link still receives no acknowledgements after the maximum number of
retries is reached, the system det ermines that the line protocol on the bundle link is down.
Before configuring this command, make sure you have used the link-protocol mfr command to
enable MFR encapsulation on the Frame Relay interface.
