Cisco IPS 7120 Very Strange behavior

[Rami Ibrahim]

---

Hello Guys, 

 Today we just experienced an ambiguous behavior. We've a Cisco IPS 7120 sensor from the old days just after rebooting, it freezed that is, all interfaces are up, ping is working fine from the sensor to FMC and vice versa but can't apply any change. Also when logging via CLI and issue "show manager" it said no managers configured and any show command displays a blank output however, before the reload we checked all show commands and all outputs were correct. 

Any ideas on what went wrong during the reload?

Thanks everyone.

Since if you decided to re-image

try below command

sudo su

/etc/rc.d/init.d/mysqld status
/etc/rc.d/init.d/mysqld restart

check the logs

If this device managed by FMC. FMC should have all the information, check if you can take any local backup and settings

sure re-image should work, since do you do not have contract to open a TAC case.

Hi balaji,

 I managed to fix the issue by Re-Imaging the device. One thing that was a nightmare is that the interactive menu couldn't found the ISO image on FTP / SCP. 

Finally solve it by using HTTP server.

Revert to the base image then register with FMC and patch update sequentially.

Thanks ☺️☺️☺️
