Description

SRX branch device in a cluster, with no fxp0 configured

Symptoms

  •  SRX Branch in a cluster
  • No FXP0 is configured, so no management of each individual node
  • Only primary device is reachable and manageable
  • SNMP is configured on the root stanza

Solution

 

 With no fxp0 configured in a cluster, only the device that is primary can be reachable (by http, https, telnet, ssh, snmp).  Traps will not be sent from the secondary ... only the primary device will be sending traps.  However, if there is some event triggered by jsrpd (impacted by some event impacting the secondary), that event will be sent over the HA link, and a trap will get sent from the primary to the SNMP Agent.  

For example, if the secondary device reboots, the primary will know a state has been changed, and a trap will get sent:
