C1100 setup and install certificate for https and VPN


Just purchased a C1111-8P running Gibraltar. Would like to install a certificate that can be used for https and VPN. Trying to follow the documentation, but got stuck with a 400 Bad Request No required SSL certificate was sent after setting the https to use the trustpoint.


So far I have done the following:

crypto key generate rsa general-keys modulus 2048

netlab(config)#crypto pki trustpoint quovadis
netlab(ca-trustpoint)#enrollment terminal pem
netlab(ca-trustpoint)#subject-name C=AU,ST=Victoria,L=Melbourne,O=myorg,OU=IT,
netlab(ca-trustpoint)#revocation-check none
netlab(ca-trustpoint)#rsakeypair 2048
netlab(ca-trustpoint)#serial-number none
netlab(ca-trustpoint)#ip-address none

netlab(config)#crypto pki enroll quovadis

<downloaded certificate request>


This provided a cer, I sent it off and i received three certificates in return, root, intermediate and entity

next step was

crypto pki authenticate quovadis

<submitted intermediate certificate>

crypto pki import quovadis certificate

<submitted entity certificate>


next step was

copy running-config startup-config

show crypto pki certificates

I can see the general purpose and signature certificates


next step

no ip http server

ip http secure-server

ip http secure-port 443

ip http secure-client-auth

ip http secure-trustpoint quovadis


show ip http server secure status
HTTP secure server status: Enabled
HTTP secure server port: 443
HTTP secure server ciphersuite: aes-128-cbc-sha dhe-aes-128-cbc-sha
ecdhe-rsa-aes-128-cbc-sha rsa-aes-cbc-sha2 rsa-aes-gcm-sha2
dhe-aes-cbc-sha2 dhe-aes-gcm-sha2 ecdhe-rsa-aes-cbc-sha2
ecdhe-rsa-aes-gcm-sha2 ecdhe-ecdsa-aes-gcm-sha2
HTTP secure server TLS version: TLSv1.2 TLSv1.1
HTTP secure server client authentication: Enabled
HTTP secure server PIV authentication: Disabled
HTTP secure server PIV authorization only: Disabled
HTTP secure server trustpoint: quovadis
HTTP secure server peer validation trustpoint:
HTTP secure server ECDHE curve: secp256r1
HTTP secure server active session modules: ALL

copy running-config startup-config


I've been pointed to several documents that really don't help, so I would appreciate knowing what I need to do.

Can I install the root certificate that I was sent without having to recreate the trustpoint and requesting certificates again? I ask this because I see in some examples that a chain is created to a root trustpoint using

crypto pki trustpoint root

enrollment terminal

chain-validation stop


crypto pki trustpoint quovadis

chain-validation continue root <- this is the line I did not include when I generated the CSR - can it be added later?


I would appreciate some help to get my webui and VPN secured

How to Ask The Cisco Community for Help

Thank you for posting a webpage that I have already looked at. I have looked at most of the websites that a google search indicates for several search terms.


You may notice that it includes details on how to chain to a root certificate.

this example has two intermediate certificates, and does not indicate how to get the certificate to work with https after installation.


My questions are:

1. do I need to request a new certificate or can I edit the trustpoint to point to a root? It appears that I will be provided with root, intermediate and entity certificates.

2. what steps are needed to ensure that https works - can a general purpose certificate be used - and what steps are involved

3. similarly for the VPN setup.

I don't believe SSL-VPN is even supported on newer IOS routers. The cisco recommended Remote Access VPN solution for cisco routers, is FlexVPN which uses IKEv2/IPSec instead of SSL.


thx Rob, this appears to apply to ASA, we have an ISR and I'm trying to follow the secure VPN setup guide.


Any pointers to ISR? I was also told that ASDM might help, but will it work with ISR?

No it doesn't apply to ASA...FlexVPN Remote Access VPN is only supported on Cisco IOS/IOS-XE routers using AnyConnect.


ASDM is only supported with ASA, not routers.
