Hi Experts,

Kindl asist me in load the IPS IOS on the IPS 4240 from rommon mode.

Note: I can only access the IPS via rommon only becuase the existing ios is cuppted and formatted.

The rommon output is give bellow:

rommon #2> set
ROMMON Variable Settings:
ADDRESS=192.168.2.16
SERVER=192.168.2.58
GATEWAY=192.168.2.1
PORT=Management0/0
VLAN=untagged
IMAGE=C:\IOS\Tftpd32\IPS-4240-k9-sys-1.1-a-6.1-1-E2.img
CONFIG=
LINKTIMEOUT=20
PKTTIMEOUT=4
RETRY=20

rommon #14> ping 192.168.2.16

rommon #0> ping 192.168.2.1
Sending 20, 100-byte ICMP Echoes to 192.168.2.1, timeout is 4 seconds:

Success rate is 100 percent (20/20)
rommon #1> ping 192.168.2.16
Sending 20, 100-byte ICMP Echoes to 192.168.2.16, timeout is 4 seconds:
??????????????

rommon #2>

The major problem is that i cannot ping the ips interface address 192.168.2.16) while i can ping all the others.

Thanks in anticipation!

Regards

Hello,

It is OK for the sensor to not be able to ping its own interface in ROMMON mode. Based on the output, it looks like the sensor is able to ping the server at 192.168.2.58. Are you having issues with the TFTP process? What happens when you issue the "tftp" command?

Hi,

From the error message the file was not found on the tftp server.

I see that you have:

IMAGE=C:\IOS\Tftpd32\IPS-4240-k9-sys-1.1-a-6.1-1-E2.img

I am guessing that this should be:

IMAGE=IPS-4240-k9-sys-1.1-a-6.1-1-E2.img

as the tftp daemon on your machine probably is using C:\IOS\Tftpd32\ as the 'root' directory of the files it is serving.

You can check this in the settings of the tftp daemon.

Best regards, Peter

Hello again,

Ok, so does 'IMAGE=IPS-4240-k9-sys-1.1-a-6.1-1-E2.img' work?

If not what messages do you get?

Best regards, Peter
