I am using cisco 2851,2821, and 2811 routers in a project.I'm facing a problem Cisco IOS problem.Our many routers are coming in ROMMON mode, when they are in production.
cisco 2851(IOS) - c2800nm-advipservicesk9-mz.124-9.T7
cisco 2821(IOS)- c2800nm-advipservicesk9-mz.124-15.T7
cisco 2811(IOS)- c2800nm-advipservicesk9-mz.124-9.T4
I am not getting the problem, why these routers are going down because of fault in cisco IOS?
I want to tell one thing that there not much CPU utilization in these routers.
Kindly anyone tell me what is this reason of this fault and how i could overcome.
The reason router goes in rommon mode is when router is not able to locate IOS image in flash or it is due to
the IOS is corrupted.
I request you to collect log.. like if you attach console while booting , router generate the logs as why router is moving in
Please make sure:
1- IOS is not corrupted by checking md5 checksum
2- giving proper path to router via. bootflash command.
Please share log to have better idea.
