Cisco 4321 sudden restart

salomidhogela — Tue, 14 Feb 2023 05:23:14 GMT

Good Day All,

I am experiencing issues with my Cisco 4321 router which keeps restarting,

ISO isr4300-universalk9.17.03.05.SPA.bin.

Please advise on the possible causes of this.

Regards,

Hi,

look at the output of the

show version

command.

The reason for the last reload should appear there

also Try working according to the following link:

https://www.cisco.com/c/en/us/support/docs/universal-gateways-access-servers/90-series-customer-premises-equipment/7900-crashes-router-troubleshooting.html

for 17.03.05 version There are a number of known bugs that cause crashes
You can see the bugs at the bottom of the attached link:

It is difficult to recommend anything only with the information that the router is restarting. It can be power supply problem, can be a hardware problem, can be routing table problem. Do you have BGP on this router? how many routes to you receive?

How about CPU and memory? What do you see in

show log ?

Do you have any Logs captured ? looks for me router is crashing.

isr4300-universalk9.17.03.05.SPA.bin

Question here, what was the OLD Version, is that working as expcted before with out any reloads ? what is the reason of upgrade to new Code.

if you upgrade as fancy, then i would go back to stable version which was working and engage with TAC for your issue.

if you upgraded due to some bug, and TAC advised to go with

isr4300-universalk9.17.03.05.SPA.bin

- then i still engage with TAC here too.

Hi,

It's a new router, I have two other routers in the environment running the same IOS but there are no rebooting issues. I tried replacing the power cable with CAB-PWR-MIEC-CLVR power code as the router was restarting frequently. I have also observed that when I prepped the router at some point it went into romon mode.

Are you facing power outage on this location?

Re: Cisco 4321 sudden restart

salomidhogela — Thu, 23 Jun 2022 10:52:37 GMT

There's no power issue onsite, I have other devices (Cisco 4321 router) connected to the same power feed but the uptime is 100%.

Re: Cisco 4321 sudden restart

balaji.bandi — Tue, 14 Feb 2023 06:06:51 GMT

power on ..boot.

do you see the image in flash - when you issue command -

dir flash:

when it ROMMON, what are you doing to boot ?

you may need console logs to capure when the next reboot accours to understand the issue.

Standby not ready to show bootvar

not sure you have RP here ?

Can you post :

- Normally this is powering problem 'only' , check power supplies and check if (external) power-feed is stable

If this was a crash, the output would say, at a minimum

reset local software.

But this is

reset power on

and this points to either a faulty power outlet or a faulty power supply.

Does the router have dual power supplies?
