Config issues on 2921 Router with SW module

bc4switch
Level 1
Level 1

I have a CISCO 2921 router with a 24 port switch module. Everything has been configured and working excepte the following, please help!!

VLAN1: 10.10.10.x,    default network for Router GI 0/0, which has IP 10.10.10.1

VLAN2: 10.10.9.x       subnet for development

Connection: router GI 0/0 is connected to SW port 17, my laptop is connected to SW port 16 with IP 10.10.9.22. VLAN setting for port 17 is: VLAN1; VLAN setting for port 16 is: VLAN2.

Issue I am having:  From my laptop, I can ping 10.10.10.1, but I can't do http://10.10.10.1

What did I miss? Thanks.

Hi,

Coul you add this and try accessing your router from the 10.0.9.0/24 subnet?

access-list 23 permit ip 10.0.9.0 0.0.0.255

Hi Bin,

You need to enable http server on your router by doing the below:

ip http server

ip http authentication local (you will need to create a username for access)

username (xxxxxx) secret (password)

You can also enable https by typing ip http secure-server

HTH.

Terence

Hi, Terence,

I have eveything you listed above.  But I simply can't access https://10.10.10.1, therefore I can't run CISCO CP.

Help.

Then you have other configuration misatkes.

Note however, Cisco CP is pretty useless.

The original post establishes that there is IP connectivity from the laptop to the router address. If https access does not work then I must agree with Paolo that there is some other issue in the configuration. A good next step would be for the original poster to post the configuration of the router so that we can identify what is the other issue.

Hi Bin,

Does CCP prompts you for a username/password? Make sure you've got a username with privilege 15 configured.

username USERNAME privilege 15 secret PASSWORD

If this still doesn't work, kindly post your show run as Rick suggested and remove any sensitive info.

Hi,

Coul you add this and try accessing your router from the 10.0.9.0/24 subnet?

access-list 23 permit ip 10.0.9.0 0.0.0.255

Sent from Cisco Technical Support iPhone App

I believe that John has correctly identified the issue. To give some supporting detail about it, this line of the config is the key:

ip http access-class 23

This uses access-list 23 to control who can use the web interface to access the router. And access-list 23 only permits a small part of a subnet. Note that this looks like the access-list that is part of the standard initial configuration of an IOS router.  And note that this access list is also controlling who can get remote access for the command line also

line vty 0 4

access-class 23 in

So if you add 10.0.9 as a permit in access-list 23 the http/https should work.

HTH

Rick

HTH

Rick

Thank you John / Richard. With this access-list, my first problem was resolved: that is to be able to access the router from 10.0.9 network.

My second problem is this: once I connect to the Router with CISCO VPN client, I got an IP address 10.0.10.30, with mask: 255.0.0.0. I am not able to access the router.  What else do I need to do?

I am glad that our suggestion about modifying the access list has resolved the first problem. The solution to the second problem is quite similar. You need to modify access list 23 and add an entry that will include a permit for an address range that includes the VPN addresses.

Do you have access to the device that is providing the VPN and can you determine what range of addresses in the the VPN pool? That is the range that you need to permit in the access list.

HTH

Rick

HTH

Rick

Rick, yes, the range is in the above config file that I posted earlier. I added access list 23 for 10.0.10, but no luck.

When I connect to VPN, my subnet mask should be 255.255.255.0, right? But is is 255.0.0.0. So I think something is  not right.

I followed CISCO documentation and example to setup the VPN access.

Perhaps you can post the current version of access list 23? I am guessing that there is something about the way that you did the permit for 10.0.10.

I can see where you intend the mask for VPN to be 255.255.255.0. But I do not see anywhere that you specify this in the VPN config. Have I missed something?

HTH

Hi Bin,

Are you referring to Easy VPN server setup on the router? By the way, I've got your email but I will be responding here on this thread. This will help other folks keep track and assist in resolving your issue if I'm not available.

Please help rate useful posts. Thanks!

Sent from Cisco Technical Support iPhone App

John,

Yes, this is Easy VPN server setup on the router. Please refer to the router configuration above.

I added the following access list:

     access-list 23 permit ip 10.0.10.0 0.0.0.255

But, no luck this time. The purpose of this exercise is that I can VPN in to the router, and then SSH to the router management interface.
