Hi I have dot1x authorization policy on my ISE server, whith result few statements in DACL

Device Authorize successfull, DACL is pushing to switch

Current configuration : 484 bytes

interface FastEthernet0/4

end

BUT it's not applayed to my session, default_acl on port is still applayed, from this PC I have any any access, like in default ACL defined.

Why it's happens?

thanks

Hello-

I have the following questions:

1. Can you post the ACL syntax that was configured directly on ISE

2. What are you trying to accomplish with this ACE:

10 permit tcp any 0.0.0.0 255.255.255.0 eq 3389

3. Post the output of the following command:

show ip access-list interface fa0/4

4. Enable debug level logging on the switch and post the output after the authentication happen. More specifically we are looking for an error related to applying the ACL to the interface

Thank you for rating!

Hi, ACL which I wat to applay from ISE server is this:

permit ip any host 10.1.1.20

permit udp any host 10.8.13.11 eq 53

permit udp any host 10.8.13.12 eq 53

deny ip any any

this line was

10 permit tcp any 0.0.0.0 255.255.255.0 eq 3389

for ASA acl, it's incorrect, I delete it.

What kind of debug I should enable, because if I debug all - my switch is going down

OK, after you authenticate, running the command: "sh ip access-lists interface fastEthernet 0/4" should display the ACL entries that are applied to the interface. You are not seeing that so something is preventing the ACL from being applied to the port. Check the logs on the switch right after the authentication happens and look for any errors related to the port/ACL

You can enable logging by:

logging trap debugging

logging buffered 32000

Sorry somehow I missed this e-mail/thread. I find it interesting that this command solved your issue. As far as I know IP device tracking is used for web auth and profling.

Again though, thank you for shaing the information! (+5 from me). If the issue is solved then the thread should be closed as well.
