Unable to reach management service and console

L1 Bithead

Hi, greeting all


my palo alto appliance(PA-850) used virtual-wire mode already, a few days before, paloalto can passaging traffic by virtual-wire pair, but the management service unreachable. even i tried to PING / HTTPS / SSH / SNMP / Console etc. and also i tried find the ARP info by network device, the device no any ARP record from Paloalto mgmt interface, then I tried connect Console cable to appliance by normal console and micro console, but my Terminal application cannot received any infomation then window still black.


does anyone have this experience? or just shutting down power to reboot? thanks so much.

This does sound strange indeed, I'd try rebooting the firewall with the console connected (the one provided with the appliance or the cisco one work best, 9600 baud; 8 data bits; 1 stop bit; No parity; No hardware flow control.) to see if it gives any sign of life


if the terminal remains blank and there's no IP connectivity, you wiull need to reach out to support to replace your device

Hi @reaper


thanks for the comment and suggest,

the situation like your comment, because i have two same model device, so i can verify problem unit of each appliance,

i tried rebooted the device, then the service has been returned already.


I think I will carry on for device state track, cuz for this problem, seems like only reboot by power-off to resolve it




I assume you have the management interface configured? Unless I read the question incorrectly, you may not be able to connect to an interface as a management interface while in vwire mode. Also if your PAN is in fips mode, then the console port is only available during the pre-boot and is shut down when the OS loads.



Hi @OtakarKlier


thanks for your kind assistance


actually, is my palo alto architecture is out of band management port unable to access and other network service still no response also, like i use CACTI to polling SNMP query mgmt interface fail / Ping fail etc.

it's good way for troubleshooting, i will try to find the fips mode possibility, then i was rebooted already, the console has been success for use.
