SRX

To see what policy is being hit by a flow:

show security match-policies ?
 Possible completions:
destination-ip       Match policy for the given destination IP
destination-port     Match policy for the given destination port) (1..65535)

[…]

source-port          Match policy for the given source port) (1..65535)
to-zone              Match policy for the given destination zone


Packet processing chain: SRX vs J-Series (Important to notice that, in j series, all nat happens after policy and routing):

CLUSTER - HACheck logs :show log jsrpd To log into shell/cli from the pair node:

rlogin -Jk -T node1

To force the failover to node 1 request chassis cluster failover node 1 redundancy-group 1

Normally, after force failover, we reset the priority values to the ones determined in the config: request chassis cluster failover reset redundancy-group 1

redundancy-group 1 {
  node 0 priority 100;
  node 1 priority 99;

This priority is only used when two devices come up at the exact same time or when preempt is enabled. (see this link)

Unrelated is the monitored interface priority. Basically the priority is subtracted from 255 (forget about the node priority! and there is a fail-over when the cumulative weights reach 0!
