Hi,
I need some advice to understand something.
When you enable LAG on reth interfaces (with LACP), you specify the minimum-link parameter. So if I have a LAG on one node with two interfaces and specify minimum-link of 1, the reth interface will not go down if only one of the two links fails. If both links fail, it will do a failover to the other node.
Now how does this play together with the interface-monitor statement in the chassis cluster statement? If I put all the interfaces in there with the weight set to 255, will the minimum-link parameter still hold? I guess not? Would I set the monitoring weight to 128 for each LAG member interface in order to only failover when 2 of 2 links go down?
Some config snippets:
Current chassis cluster config:
chassis {
cluster {
control-link-recovery;
reth-count 16;
network-management {
cluster-master;
}
redundancy-group 0 {
node 0 priority 100;
node 1 priority 1;
}
redundancy-group 1 {
node 0 priority 100;
node 1 priority 1;
preempt;
gratuitous-arp-count 5;
interface-monitor {
ge-0/0/3 weight 255;
ge-9/0/3 weight 255;
ge-2/0/0 weight 255;
ge-11/0/0 weight 255;
ge-2/0/4 weight 255;
ge-11/0/4 weight 255;
ge-2/0/5 weight 255;
ge-11/0/5 weight 255;
ge-2/0/8 weight 255;
ge-11/0/8 weight 255;
ge-2/0/1 weight 255;
ge-11/0/1 weight 255;
ge-11/0/6 weight 255;
ge-2/0/6 weight 255;
}
}
}
}
One of the reth interfaces, consisting of 2 physical ethernet links on each node:
show interfaces reth0
vlan-tagging;
redundant-ether-options {
redundancy-group 1;
minimum-links 1;
lacp {
passive;
}
}
In this scenarion, if one of the links on one node fails, would it failover (because interface-monitoring for each interface is at 255), or would it stay up because of the minimum-links = 1 statement?
Thanks
