Configure the Keepalive Parameters

Configuration Condition

Before configuring the Keepalive parameters, first complete the following task:

• Create one MLAG domain

Configure Source, Destination Address and Other Parameters of Keepalive Packet

To establish the MLAG system correctly, the source and destination addresses of keepalive packet must be configured, and the L3 layer between two nodes is reachable.

The VLAN corresponding to the L3 interface to which the source IP address of the keepalive packet belongs cannot be included in the VLAN where the peer link interface is located.

Table 13-12 Configure the source, destination address and other parameters of the Keepalive packet

Configure Sending Interval and Receiving Timeout of the Keepalive Packet

When receiving the previous keepalive packet or when starting to listen, start the receiving timeout timer with the receiving timeout. If the timer does not receive the next keepalive packet before the expiration, it is considered as LOST.

Table 13-13 Configure the sending interval and receiving timeout of the Keepalive packet

Configure the Quiet Time of the Keepalive Packet

After the peer-link is down, the slave node enters the quiet period. The keepalive packets received during the quiet period will be ignored and will not be processed. The keepalive packets received after the quiet period will be processed. The quiet period is to wait for the keepalive packets on the link to be received and sent completely, so as to prevent false detection due to packet delay.
