Cisco ip phones authenticate 802.1x with cisco ise 1.3

Dear all,
I want to configure cisco ise 1.3 with 802.1x , to authenticate cisco ip phones ( CUCM 10.5.2 ) with LSC certificate.
How I have to configure cisco ise authentication rules for 802.1x with cisco ip phones? Are there any configuration examples ?
Thanks

following are ISE 802.1x sample authentication rules..you can change the protocol (Policy -> policy elements - > results -> authentication and you can select the proctocal)

Cisco ISE FlexAuth with 802.1X PCs and IP Phones as MAB multi-domain Q?

Cisco ISE FlexAuth with 802.1X PCs and IP Phones as MAB multi-domain Q?
Im trying to follow the trustsec 2.1 guide on IP Phones into LowImpact mode.
I can get a PC on its own to authenticate via dot1x/tls
I can get a Cisco IP Phone on its own to authenticate via MAB.
When the two are on the same switchport, the phone will authenticate but not the PC. ISE logs EAP timeouts.
The switchport has the LowImpact port ACL of
ip access-group ACL-DEFAULT in
The IP Phone gets a dACL that allows it ok.
I assume MAB phone and dot1x PC is supported? Any ideas?
Thanks in advance.

802.1x with alcatel phone with cisco acs 5.0

Hi All, can any one has done the implementation of 802.1x with alcatel phone where pc will be behind the phone and cisco switch ports are configured as trunk. Trunk native vlan is data vlan for pc and trunk carrying voice vlan.
when trunk mode is enabled I can not configure 802.1x on trunk interface. does any one help me to get rid of this situation..
Thanks

Hi,
Did you find any solution?. Did you tried with the command switchport voice vlan?.

Catalyst Express 500 802.1q with non-Cisco Phones

This weekend we spent hours trying to get 802.1q tagging to work on a VLAN with ShoreTel phones. The user interface on this switch seems to only allow "Cisco-Voice" VLAN, without any specifics. This didn't work. The specs on this switch say that the .1q is supported, but we couldn't figure it out. The more expensive switches were easier to configure for Voip QoS.
Can anyone advise me on the tricks to getting this to work with the lower end Catalyst Express 500? Or does this switch only support 802.1q with Cisco phones?

Cisco IP Phone uses CDP to let the ip phone know what vlan it's suppose to be (via voice-vlan). shore tel would definitely not use CDP since CDP is cisco proprietory, so it's voice vlan must be defined on it, I rememer Avaya being the same way. So, having said that, just make sure that the Shore tel Ip phone are in the right vlan. what does not work anyway? shore Tel IP Phone will not come up? Will not get it's configuration from it's software PBX? Use the smartport configuration on CE500.

Cisco ip phone 9971 registration failed with CME 8.6 on WAN

Dear Sir
Subject: Cisco ip
phone 9971 registration failed
with CME 8.6 on WAN
I have a WAN simulation with one Cisco2811 router one Cisco1841 router (connected with fast Ethernet interface) plus one layer 2 switch.
I upgraded the 2811 IOS to 15.4M and installed CME8.6, when we tried to add 9971 sip phone If the traffic goes throw LAN (Same subnet- directly from switch to 2811) everything is fine and the SIP phone (9971) added with no problem but when I change the subnet and traffic goes throw WAN
( from 1841 routed to 2811 with default route) my phone didn't register.
It will be great if anybody could help!!
If you can solve my problem, I will be happy to compensate.

Try binding SIP to an interface on which Phone can reach (Use "voice service voip" "sip" and then bind)

Cisco ISE authenticating Ip Phone 7942

Hello,
I am installing Cisco ISE soon and have a question. Why can't I authenticate Cisco IP phone model 7942 using 802.1x? I see that the phone has this option (it is not enabled). I am told that Cisco IP Phones must be authenticated on ISE by using profiling or MAB. This uses a costly advanced license to accomplish this.
Has anybody had any luck in this area?
Thank you,
Bob

I have successfully deployed 802.1x for wireless IP phones using MIC. The only real problem I have with this approach is the inability of ISE to authenticate the username from certificate against anything but an external database. As a result I have been forced to use a static endpoint group for the MAC addresses of the allowed phones to meet the organisation's security stance. Just wish EAP-TLS could go against an internal database.

Cisco ISE for 802.1x (EAP-TLS)

I work for a banking organization and security is an area that needs to be improved continuously. I am planning on implementing Cisco ISE for 802.1x together with a Microsoft PKI for certificate issuing and signing.
I am currently trying to implement this in our test environment and I have managed to do a few basic bootstrapping tasks. I need someone to push me into the right direction as to how I can achieve what i am seeking.
I will use Cisco 2900 series switches on the access layer and a few HP switches as well which supports 802.1x.
I want to configure the ISE to process authentication requests using 802.1x EAP-TLS (Certificate Based). All the workstations on the domain needs to authenticate itself using the certificates issued to it by the Certificate Issuing Authority.
I have already managed to get the PKI working and have rolled out the certificates on all the workstations on the test environment. I can't seem to configure the Authentication portion on the ISE.
I request if someone can guide me or direct me to materials that can help achieve the above requirements. The guides available on the Cisco website are overwhelming and I can't seem to figure out how I am supposed to configure the authentication portion.

Hello Mubashir,
Many timers can be modified as needed in a deployment. Unless you are experiencing a specific problem where adjusting the timer may correct unwanted behavior, it is recommended to leave all timers at their default values except for the 802.1X transmit timer (tx-period).
The tx-period timer defaults to a value of 30 seconds. Leaving this value at 30 seconds provides a default wait of 90 seconds (3 x tx-period) before a switchport will begin the next method of authentication, and begin the MAB process for non-authenticating devices.
Based on numerous deployments, the best-practice recommendation is to set the tx-period value to 10 seconds to provide the optimal time for MAB devices. Setting the value below 10 seconds may result in the port moving to MAC authentication bypass too quickly.
Configure the tx-period timer.
C3750X(config-if-range)#dot1x timeout tx-period 10

Cisco ISE and authentication for 802.1x printer

Hello
What is the best practice to authenticate a 802.1x printer in Cisco ISE?
The printer can store a certificate for authentication and support EAP-TLS.
Thanks for answer.
Marco

EAP-TLS is the way to go. It is way way way more secure than MAB and profiling. However, the question is "How much of a hassle is it going to be to put a certificate on each printer?" Moreover, "What methods do I have (if any) to renew those certificates when they expire?" If have to manually generate a CSR and install a cert on each printer then it can quickly become an administrative overhead nightmare. With that being said, you can use MAB and profiling but just make sure that you lock down the access that those printers get. For instance, do they need access to the internet? Do they need access to anything else but the print server and/or open to all IPs access but only on the printing ports.
I hope this puts you in the right direction!

Cisco ISE: 802.1x [EAP-TLS] + List of Applicable Hot-Fixes

Dear Folks,
Kindly suggest the list of all possible Hot-Fixes required for the Cisco ISE EAP-TLS solution... We have applied 9 HotFixes so far. But, still the connectivity is intermittent. Is there any list for all applicable Hot-Fixes?
OS = Win 7 SP1 (32/64 Bit) and Win 8

Hi Mubasher
KB2481614:      If you’re configuring your 802.1x settings via Group Policy you’ll see      sometimes EAP-PEAP request from clients in your radius server log during      booting even if you’ll set EAP-TLS. This error happened in our case with      1/3 of the boots with some models. The error is caused by a timing problem      during startup. Sometimes the 802.1x is faster and sometimes the Group      Policy is, and if the 802.1x is faster than the default configuration is      taken, which is PEAP. Which lead to a EAP-NAK by the radius server.
KB980295:      If an initial 802.1x authentication is passed, but a re-authentication      fails, Windows 7 will ignore all later 802.1x requests. This hotfix should      also fix a problem with computers waking up from sleep or hibernation –      but we’ve disabled these features so I can’t comment on them.
KB976373:      This hotfix is called “A computer that is connected to an IEEE      802.1x-authenticated network via another 802.1x enabled device does not      connect to the correct network”. I can’t comment on this, as we’ve not      deployed 802.1x for our VoIP phones at this point.I would guess it is the      same for Windows 7 too. The linked article tells you to install the patch      and set some registry key to lower the value.
KB2769121:      A short time ago I found this one: “802.1X authentication fails on a      Windows 7-based or Windows 2008 R2-based computer that has multiple      certificates”. At time of writing I’m not sure if it helps for something      in my setup. According to the symptoms list of the hotfix, it does not,      but maybe it helps for something else, as the one before does.
KB2736878:      An other error during booting – this time it happens if the read process      starts before the network adapter is initialized. Really seems that they      wanted to get faster boot times, no matter the costs.
KB2494172:      This hotfix fixes a problem if you’ve installed a valid and invalid      certificate for 802.1x authentication. The workaround is just deleting the      invalid certificate. I’m not sure at this point if it affects also wired      authentication.
KB976210:This      problem occurs only during automated build processes and if you use an EAP      method which needs user interaction – as I don’t do that I can’t comment      on this hotfix.

802.1x with Vlan assignment and IP phone and PC

I have a Catalyst 4510R and I want to im plement 802.1x with dynamic VLAN assignment via Radius server. I am going to plug to switch ports Cisco IP phones and PCs (PCs are plugged in the IP phone).
For this implementation I need to configure the switch port in mode trunk because I have voice vlan corresponding IP phone and data vlan corresponding to PC.
However I have read that I can not enable 802.1x on a trunk port.
How could I configure this?
I need that when the PC is authenticated correctly is assigned to his cooresponding data vlan and the IP phone is in the voice vlan.
Thanks

You should configure the port as an access port with an aux-vlan. Here's an example:
interface GigabitEthernet2/2
switchport access vlan 701
switchport mode access
switchport voice vlan 702
load-interval 30
qos trust device cisco-phone
qos trust cos
auto qos voip cisco-phone
dot1x pae authenticator
dot1x port-control auto
tx-queue 3
bandwidth percent 33
priority high
shape percent 33
spanning-tree portfast
spanning-tree bpduguard enable
service-policy output autoqos-voip-policy
Hope this helps,

802.1x with the 6901 IP Phones

Hello Experts,
We are testing the 802.1x with the 6901 IP Phones. And we can see on ACS "EAP Session Timeout" In the logs, and cansee that the EAP Username used by the phone is CP-6901-SEPB8BEBF220041.
How ever following issues are stopping us to deploy it fully.
How to enter password in IP Phone since It does not have LCD screen.
Wetried IVR option, but it gives pin as an option, Is this Pin used as passwordfor 802.1x authentication.
Dowe use any default password for this to work.
Thanks in advance for the help.
Regards
Ronak Patel

Overall, you need to try and deal with the fact that a machine can disappear from the network and the network may not know about it directly (i.e. Link doesn't go down).
I have no idea what other phones do, but Cisco phones send an EAPOL-Logoff when something is unplugged. This lets the switch know directly, and 1X session start is torn down immediately, closing what would be a security hole.
Fundamentally, re-auth is a workaround only, and this is not the reason to enable re-auth to begin with.
If your phone doesn't send an EAPOL-Logoff in this case, the switch might be left thinking an attack is underway when someone else tries to plug in (with presumably a different MAC). You do NOT want this to occur.
Hope this helps,

Cisco ISE integration with third-party firewalls

Can Cisco ISE be integrated with a third-party firewall (such as Checkpoint), to provide authentication/authorization services to remote VPN user devices (based on device MAC address)?
The remote user would establish a VPN connection to a third-party firewall, based on a username/password authentication, but the user would only be allowed to send/receive traffic to the internal network if the MAC address of the device being used was authorized by Cisco ISE.
Thank you in advance.

Rui,
I do not think the vpn client sends the ip address in a called-station-id, that might be the public ip address that the client is initiating the request from. If you have an existing radius server or can run a packet capture you should be able to verify that.
If the client does send the mac address in the radius packet then you can create a custom condition that can be used to check the mac address along with the username to allow it access to the session. However in VPN deployments there is no concept of profiling since 802.1x deployments usually include the client's mac address.
Thanks,
Tarik Admani

Strip @domain on LDAP Integration with Cisco ISE?

Hi there ,
I got a WLC conntect with a Cisco ISE. There are two SSID authenticated against the ISE.
One SSID has AD-Integration as External Identity Source, the other SSID is authenticated through LDAP.
Authentication ist working fine.
When an user authenticates through LDAP, he/she has to enter "username@domain". The protocol is EAP-GTC.
How can I change the ISE that the user has only to enter "username" and the "@domain" part ist already set on the ISE?
Thansk a lot,
Norbert

From the user guide it seems that LDAP only allows you to strip the prefix/suffix and can't add the suffix.
http://www.cisco.com/en/US/docs/security/ise/1.1/user_guide/ise_man_id_stores.html#wp1054421
Strip start of subject name up to the last occurrence of the separator
Strip end of subject name from the first occurrence of the separator

Cisco ISE with EAP-FAST and PAC provisioning

Hi,
I have search with no result on this topic. So, Does anyone have implemented Cisco ISE authentication with EAP-FAST and PAC provisioning ?
Since I have an issue with internal proxy, user required to authenticate with an internal proxy before granting access to the internet.
If you have any documents, it would be appreciated for me.
Thanks,
Pongsatorn

From what I understand a Internet proxy PAC and a eap-fast PAC are two different purposes.
Is that what you are trying to get clarification on.
Basically eap fast PAC provisioning is a PAC that s provisioned when a client authenticates successfully. The client provides this PAC for network authentication and not proxy authentication.
