Cisco ASR “private key not found” Error

Leave a comment Posted by on January 13, 2022

I was working on a ASR running code: asr1000rp1-ipbasek9.02.02.01.122-33.XNB1.bin. I wiped the config and started over from the last setup, and tried to SSH in. I was continually getting denied, and check the router – This error showed up.

1w2d: SSH2 0: RSA_sign: private key not found
1w2d: SSH2 0: signature creation failed, status -1

My first thought was to recreate the cert – so I did, still a no go.

I then recreated the cert with a different label or name, and then told the ASR to use this key pair instead – and everything worked. Its like I could not find the default key pair. The commands that I did to fix this are:

crypto key gen rsa general-keys label KEYPAIR-1 modulus 2048

ip ssh rsa keypair-name KEYPAIR-1

Then the ASR gave this back:

Jan 13 07:08:51: %IOSXE-7-PLATFORM: SIP0: sntp: resetting on error 0.273 > 0.1
Jan 13 07:08:52: %SSH-5-DISABLED: SSH 2.0 has been disabled

Cisco ASR 1002-X bandwidth license increase

Leave a comment Posted by on September 23, 2021

I installed a new license to a ASR 1002-X going from the default 5 gig to 20 gig throughput. Installing the license was no problem, but after the reboot nothing changed. I found that I had forgotten to change the hardware throughput settings – I thought the license would jus take care of this, but it didn’t.

Here are the commands/options to get the hardware throughput to match the license

First – lets check to make sure what the level is –

ASR#show platform hardware throughput level
The current throughput level is 5000000 kb/s

You can also do a show version and see this info.

Now, lets change to our installed license throughput level.

ASR(config)#platform hardware throughput level ?
10000000 throughput in kbps
20000000 throughput in kbps
36000000 throughput in kbps
40000000 throughput in kbps
5000000 throughput in kbps

ASR(config)#platform hardware throughput level 20000000

exit, and save config. The throughput level does not kick in until a reboot. After the reboot

ASR#show platform hardware throughput level
The current throughput level is 20000000 kb/s
