Firewall running NSRP is in the (I) Inoperable state. How do I fix if monitoring interfaces with NSRP?

  [KB11327] Show Article Properties


Summary:
Firewall running NSRP is in (I) state, and the firewall is configured to monitor interfaces.  How do I get the firewall out of the (I) state? How do I fix this situation?
Symptoms:
Symptoms:
  • Firewall running NSRP is in (I) state, and the firewall is configured to monitor interfaces.  How do I get the firewall out of the (I) state? How do I fix this situation?
  • When you run the following commands, you see that a monitored interface is down:
  get nsrp | inc device
  get event

For example:
In this case you can see that monitored interface e0/0 is down:
SSG550(I)-> get nsrp | inc device 
device based nsrp monitoring threshold: 255, weighted sum: 255, failed
device based nsrp monitor interface: ethernet0/0(weight 255, DOWN)
device based nsrp monitor zone:
device based nsrp track ip: (weight: 255, disabled)
SSG550(I)->

In the "get nsrp" output you see:
group priority preempt holddown inelig   master       PB other members
    0      100 no             3 no      8347392     none myself(inoperable)

You also notice event log messages related to this change:
  
2008-04-09 06:15:27 system crit  00075 The local device 8345472 in the
                                       Virtual Security Device group 0
                                       changed state from primary backup to
                                       inoperable.
2008-04-09 06:15:26 system notif 00513 The physical state of interface
                                       ethernet0/0 has changed to Down.

Solution:
Check the cables connected to the interface in question, in this case eth0/0.  Check to see if the interface is manually shut down on the firewall. (In this case, check if the config has the command "set int ethernet0/0 phy link-down").
Also, check the switch and switch port that the interface is connected to.   If the cable is connected, but the interface is still down, try using a different cable or a different switch port.  

After bringing up the monitored interface, the output of  'get nsrp'  will show that the monitored interface is UP, and the firewall prompt will no longer report that it is Inoperable (I):
 
SSG550(B)-> get nsrp | in dev
device based nsrp monitoring threshold: 255, weighted sum: 0, not failed
device based nsrp monitor interface: ethernet0/0(weight 255, UP)
device based nsrp monitor zone:
device based nsrp track ip: (weight: 255, disabled)
SSG550(B)->
