SRX

there are  redundancy-group 0 and  redundancy-group 1 on chassis cluster ,and they are active on node 0  .the chassis cluster  is in active/passive mode , my question is if there is a  failover on group 1 , and group 1 now is active on node 1 . whether the  cluster can still forward traffic ? why , if not ,what can i do 

Yes, this is possible.  Node 0 will effectively be secondary for data plane, and the packet will then traverse across the HA link to node 1, and then go out the revenue port of that node.  That is classic Z-mode traffic.

how about in SRX , i wonder why when the output of show chassis cluster status is below , i have to failover manullay show chassis cluster status Cluster ID: 1 Node Priority Status Preempt Manual failover Redundancy group: 0 , Failover count: 2 node0 255 primary no yes node1 100 secondary no yes Redundancy group: 1 , Failover count: 4 node0 200 secondary no no node1 100 primary no no

The output you have provided is as folows :-

 

Cluster ID: 1
 Node Priority Status Preempt Manual failover
 
 Redundancy group: 0 , Failover count: 2
 node0 255 primary no yes
 node1 100 secondary no yes
 
 Redundancy group: 1 , Failover count: 4
 node0 200 secondary no no
 node1 100 primary no no

 

RG0 is the routing engine which is active on node 0.

RG1 is the dataplane which would actually pass the traffic and is active on node 1.

 

So in such a scenario, all the traffic is being handled in RG1 i.e. on node 1.

 

It would be forwarded through the node 1 member interfaces of the corresponding reths.

 

There would be no issue in passing traffic in such a scenario through the SRX.

 

Hope this helps.
