Cisco WAN :: 877 / Setup A PPP Dialer To Present Empty Credentials?
Sep 7, 2011
I am trying to copy a setup from a Nortel IAX100 where the carrier provides two ATM PVC's over ADSL - one for voice (VoIP) and one for data (IP). Relevant lines from the backup of the IAX's configuration include the following for the PPP authentication over the voice circuit:
<wan_8_32>
<entry1 vccId="1" conId="1" name="Voice" protocol="PPPOE" encap="LLC" firewall="enable" nat="enable" igmp="disable" vlanId="-1" service="enable" instanceId="1509949441"/>
</wan_8_32>
<pppsrv_8_32>
<ppp_conId1 userName="" password="" serviceName="" idleTimeout="0" ipExt="disable" auth="auto" useStaticIpAddr="0" localIpAddr="255.255.255.255" />
</pppsrv_8_32>
The null username and password for the PPP connection have me a bit stumped. Does the PPP connection not use any authenetication at all? (Is that possible/likely? How could I deubg it?) Or does does the IAX100 supply a chap/pap response with null credentails? (If so, how would I duplicate that using an instruction to a dialer interface?I am configuring an 877 with 12.4T and advanced IP services.

This is a friend's computer, who bought it yesterday Acer desktop Windows 7 premium 64 bit. He asked me for assistance in setting it up, and I did that . IE8 and Mozilla Firefox were working. Later in the evening, he called and said that his computer had no internet access, though the laptop he had was working. This morning, I wnet to his place, reset the model and the router, and it was working fine. He called now and said that it is not working again. The service provider did not find any fault with the connection.

I've just got a new AP 1250 series, and I was trying to configure the Radio for the 2.4Ghz spectrum using the interface dot11radio 0 and I've just noticed that this controller is not present so I cannot configure it so I wonder is it could be a HW problems as it looks to me or there is another way to enable this.
I never have an issue like this before so I want to first check with you before going back to our vendor.
Here is some of the details I get from the AP itself:
System image file is "flash:/c1250-k9w7-mx.124-10b.JDA3/c1250-k9w7-mx.124-10b.JDA3"

I've been having some problems with my Ethernet connection lately.I unplugged my laptop from the Ethernet connection I had at my old place.At two different locales, I have tried to use an Ethernet connection in order to get better speed (the wireless at the first locale was non-existent and at the second it is extremely slow in my room). I have done so with two separate cables that I have tested on others' computers and found that they are perfectly fine. That, of course, leads me to believe that it is my computer and is either a hardware or software problem (here's hoping it's the latter).Anyway, my laptop is a Dell Inspiron 1720 (purchased in 2006). About a year ago, I updated to Windows 7 from the pre-installed Vista. Never had any problems (as I said, everything was fine up until about a week ago). The installed card is a Broadcom 440x 10/100 Integrated Controller. Everything under Device Manager indicates that the hardware is working properly and has all of its drivers installed, but nothing is working.I have tried to uninstall and re-install the drivers (albeit by allowing windows to find them automatically), but the result is the exact same.I have checked the port and found that there is no debris or obstructions. My computer hasn't been dropped or mishandled in any way.I'm currently being housed on the campus of Delta State University, which is why this appears, but here is the report: [code]

I an currently running Cisco (ACS 5.2.0.26.3) and attempting to get my Cisco 5508 WLC's (7.0.98.0) loaded into ACS for TACACS+ authentication for managment users.
However I keep getting the following error:
*emWeb: Sep 14 14:44:45.931: %EMWEB-1-LOGIN_FAILED: ews_auth.c:2104 Login failed for the user:test_tac. Service-Type is not present or it doesn't allow READ/WRITE permission.
Now I've attempted the step-by-step using the following URL but to no avail.( there are some slight differences in ACS 5.2)
[URL]
Latest WLC configuration guide I could find (Software Release 7.0 June 2010) isn't much useful either.

I recently tried to deploy an ACS appliance with version 5.2 installed on it for a customer.
After setting up the WLC to use the ACS as a radius server, and successfully testing connection from the ACS to the AD, I get an error message " 12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate" anytime a client tries to connect to the network.
This is surprising because I had already generated a certficate for the ACS from a CA and binded the CA signed certificate with the ACS, I also specified the CA in the client machine's wireless properties and checked the "validate certificate" button.
When I tried to connect using the internal identity store, the client was successfully authenticated without any certificate issues.

I am setting up a new ASA. Actually it's an old 5510, but this is a new temporary install until the one we ordered comes in. Everything is working except for SSH. I have SSH open on the inside and outside interfaces and I get a prompt when I try to SSH to it from either the inside or outside. But after I put in my username and password it tells me that my credentials are invalid. I am using a local username/password, not AAA and it accepts that username and password for the console. Console and telnet (password only) both work so I can get in to make changes. When I debug SSH, the error states that my username and password are incorrect. But this happens even when I create a new, simple username/password to test. I've even gone so far as to copy/paste the username and password into the login window just to be safe (making sure I don't copy spaces, etc). Below is a copy of the SSH Debug output followed by a sanitized copy of the config. I have AAA configured for remote VPN users, but not for access to the ASA. Also, this problem existed before I created the AAA settings for the VPN users. Also, I have zeroized and regenerated the RSA keys a couple of times to no avail. [code]

I have an 837 ADSL router that the customer is upgrading from a 3 meg circuit to a 10 meg circuit.
The previous vendor used PPOE for connection and we used a dialer 1 interface to make the connection with a user name and password.
The new connection is a straight WAN DHCP no username or password needed.
I realize I can change the dialer interface from negotiate to DHCP but do I still need it ?
Can I replace the dialer 1 interface with IRB ? Should i just keep the Dialer 1 interface since the device is currently set that way and just remove the PPP negotiation from dialer 1 ?

How to upgrade from LMS 3.0 December 2007 update to LMS 3.1 or LMS 3.2. The problem is the large number of C2960S-24TS-L switches that my organization has and cannot managed them.. I tried to upgrade devices through Software Center but always Ciscoworks informs me with the following message."Error while downloading package information from [URL] for the selected products. See the log file for details". Also i can not run EOL/EOS inventory report. The message is " INVREP0102: Cisco.com user credentials are invalid. Enter correct credentials." I check my credentials and is right. The server has access to www through proxy without any restrictions. In the past I've already updated devices through the software center. Also in the past i ve run EOS/EOL inventory reports.The LMS 3.0 December 2007 has the following products LMS3.0.116 May 2008

i'm having some trouble pushing CLI templates to controllers in my lab. i get an invalid credentials error but it is random. sometimes i can push the template fine but 30 seconds later if i push the same template it will fail with error. several minutes later try it again and it fails. i have verified the credentials by reconfiguring them consistantly accrosss the devices but if the credentials were actually wrong it should fail every time, not intermittently. there are also 2 controllers i am testing this against and it is also random which controller fails. on the instances where i don't get the credential error my CLI template fully executes without error.
i am using WCS 7.0.230.0 on WIN2K and two 4400 controllers running 7.0.230.0.both controllers are configured with SNMPv3 and SSH. telnet and lower versions of SNMP are disabled.

We have a building with 6 Cisco Airnet 1140 connected to a Cisco 2100 WLC, all tied into a nice Central Certificate server and a Win2008 NPS/Radius server on a Win2008 AD. Our trusted PC wireless access is fine, with domain laptops with certificates authenticating with DHCP all round the building. We use GP to apply settings to an AD integrated Proxy server for internet access.
The problem I now have is with guest access...
We are an education establishment, so students could turn up with anything from a laptop to an iPad to an Android phone, which immediately rules out using proxy PAC files to configure the proxy.
What I really want is a method of using the radius to verify the guest user against their existing AD user account, which I believe is possible. The one snag we have is in order to avoid the user having to configure the Internet proxy we would have to switch it to a transparent mode, which immediately restricts our ability to report on AD username, we would only have an IP address to report on, which is next to useless!
We've looked at a Gateway product (Astaro), which integrates the Filtering onto the Gateway, but the downside is that you have to use their APs, so we would be replicating existing work, whilst also managing two filters.

I have applied a crypto map (fo ipsec vpn) on the dialer interface (for PPoE connection) in Cisco 2800; every time when the router restarts the crypto map is removed from the dialer interface even though i save the configuration every tim when i apply the map on the interface. Is there any way that the crypto map remains there on the dialer interface after the restart of router.

I am having an issue with Cisco 1812j Router.
I have 2 1812j router. One router I accidentally lost the password so I reset the password as following link. [URL]
After that I could not submit "dialer" command. Like this.
c1812j-01(config)#int bri0c1812j-01(config-if)#d?dampening default delay descriptiondot1q dot1x down-when-looped dxi
c1812j-01(config-if)#
There is no choice to use "dialer" command.
The other Router is as below which looks ok.
c1812j-02(config)#int bri0c1812j-02(config-if)#d?dampening default delay descriptiondialer dialer-group dot1q dot1xdown-when-looped dxi
I guess I did something wrong to reset the unit.

having some issues with a configuration using a Dialer interface. The interface comes up and the VPN tunnel comes up, but cannot access any network resources or the Internet.
The things that concern me most are my access lists as I have the static IP address that we are assigned via PPPOE - the IP never changes, but not sure if I can define it in the ACL or if I should be using an ANY tag.
Note: I've changed some IPs and username for security reasons.

I'm trying to configure WLAN authentication on my WCS to prompt users about their credentials.I'm using a Windows 2008 NPS as Radius server but I can also use a Cisco ACS 3.3 if needed.With each setup I tried, the credentials are sent automatically to the Radius server using the Windows user session credentials.How can I force the WCS to ask for a username and password before sending them to the Radius Server ?

I have been reading article url....wp1430161 and I am trying to get my head around the type of port authentication Methods & Modes I am going to require for a Proof of Concept using a Cisco ISE as the Authentication Server.
The switchport will have a single IP Phone in a Voice VLAN and then a Single host in a Data VLAN. Reading this article, I think I should be configuring "802.1x" authentication method using "Single Host" Mode.
However will that support a Downloadable ACL dependent on the user credentials? And will it allow a restricted ACL to be downloaded if authentication of the Machine or the User fails.? I dont really want to create & manage Guest & Remediation VLANs with thier respective ACLs on every switch in my enterprise, including our remote branch offices.
