DES-7200 Configuration Guide Chapter 4 DLDP Configuration
4-3
Note
1) This function is implemented with the help of ICMP ECHO
packets. The peer device should enable the ICMP
response function.
2) The precondition of enabling this function is that the
interface is in UP state.
3) After this function is enabled, if the interface is in down
state, the IP address of the interface cannot be modified.
4) In the case of detection across network segments, the
next-hop IP address should be configured. For example,
the local interface IP address is 10.1.1.1 needs to detect
30.1.1.1 through the 20.1.1.1 gateway, the next-hop IP
address 20.1.1.1 should be configured.
4.2.3 Configuring Interval
Setting heartbeat intervals can change the frequency of sending handshaking
packets for link detection.
Command Function
DES-7200(config-if)# dldp ip interval val
It is used to set the interval for
device link detection.
4.2.4 Configuring Retry Times
Command Function
DES-7200(config-if)# dldp ip retry val
It is used to set the threshold of
error times during device link
detection.
4.2.5 Configuring Active/Passive
Mode
Command Function
DES-7200(config-if)# dldp passive
It is used to set device link
detection to work in passive
mode.
