DES-7200 Configuration Guide Chapter 4 DLDP Configuration
4-4
4.2.6 Configuring Resume Times
Command Function
DES-7200(config-if)# dldp ip resume val
It is used to set the threshold of
resuming the device link. The
threshold indicates that the times
for receiving continuous DLDP
detection packet responses
before the link status is changed
from DOWN to UP. The
resumption time is related to the
interval for sending link detection
packets set by running the dldp ip
interval command. That is, line
resumption time = resume times *
dldp ip interval.
Note
This function is used to avoid device link oscillation. For
example, when users run the ping command to detect link
status and the results show that some links are not connected
all the time, links are oscillated all the time. That is, link status is
always changed between UP and DOWN or ARP is always
switched over. Setting a greater resume value can avoid this
problem. Only when the number of detection packet responses
received by the link reached the threshold set by using the
resume command, link status is changed from DOWN to UP.
4.2.7 Clearing the Records of the
Times when DLDP Status is
Changed from UP to DOWN
Command Function
DES-7200(config-if)# clear-dldp[all] [ip [nexthopip]]
DES-7200 routers can record the
times of UP and DOWN status of
device links. Running the
clear-dldp command can clear
the recorded times and begin to
record the times.
