IPSLA conf auto erasing

[Robo123]

Hi Team,

I have a Cisco 2811 device running with "c2800nm-advsecurityk9-mz.124-22.T2.bin" we have configured failover mechanism in to the same chassi.

ip sla 1

icmp-echo  <isp ip>  source-ip  <ip address>

threshold 2500

frequency 120

timeout 3000

ip sla schedule 1 life forever start-time now

once the device is rebooting the same configuration is erracing automatically more over even if we configure source ip after saving the same is changing surce IP as 0.0.0.0

Kindly comment on the exact issue on the device.

Hi

Check its corectly saved in startup with below to see if config saved

#more nvram:startup-config

check your config register is set to 2102

also have you tried a newer image thats very old you may be hitting a bug

You can still download the images online it is EOL alright but there still up there link below on the site to download.

i would go for a v15 but you may need a DRAM increase depending what your hardware has as the older 2811 images only required 256/64 / newer images require 512/128

Hi Marks,

The suggested 15.1.4M4 which is having software advisary.Kindly let me know the  stayable version.

Your just going to have to check them , there EOL whats there is what you have choice with Cisco are not making anymore , i dont have any 2811s there to test , end of life so i cant have them in operation

If there all software advisory you will just have to take a chance , thats the problem with having equipment software out of support

Hi Mark,

 Kindly let me know "c2800nm-advsecurityk9-mz.151-4.M10.bin" is it stayable version.Even this version is having same DRAM/FLASH space which is meeting my requirement.

Please suggest on the above.
