How to make redirection work for HP5130 switch

dgaikwad — Thu, 04 Oct 2018 07:08:48 GMT

Hi Experts,

We are deploying ISE for our wired environment and we have a site that majorly has a mix of HP switches (Aruba and H3C).

The configuration and testing of the Aruba switches was seamless, now we are stuck with HP5130 switch, the redirection is not working.

What I see is when I use the attribute HPE-Captive-Portal-URL, I see that ISE pushes the URL, but the user is not able to open the page, he just get a blank page on the browser.

While looking for reference documents, I came across a document that talked about adding these two H3C specific attributes to NAD, attributes #210, H3C-AVPair and attribute #250, H3C-Web-URL.

If I use any of these attributes, attributes #210, H3C-AVPair and attribute #250, H3C-Web-URL, there is no redirection URL being sent by ISE in it.

As, you can see in the attached screenshots.

Has anyone successfully configured redirection on HP5130 switches?

Any pointers much appreciated.

Hi Dinesh,

please refer the NAD profile here - https://communities.cisco.com/docs/DOC-70347

Also please refer the discussion - https://community.cisco.com/t5/identity-services-engine-ise/h3c-s5130-integration-with-ise-2-3/td-p/3600494

Meanwhile , Can you send me screenshot of default acl and dACL from ISE ?

you can send me the acl snapshot from the NAD port as well.

Thanks,

Nidhi

Hi Nidhi,

As off now we are not pushing any dACL to the endpoints, here is the ACL that I have configured on the switch for redirection;

[NAC-5130-2]display acl 3003
Advanced IPv4 ACL 3003, 29 rules,
ACL's step is 5, start ID is 0
rule 0 permit ip destination <ISE Server> 0
rule 5 permit udp destination-port eq dns
rule 10 permit udp source-port eq bootpc destination-port eq bootps
rule 15 permit udp source-port eq bootps destination-port eq bootpc
rule 20 permit tcp destination-port eq 2967
rule 25 permit tcp source-port eq 2967
rule 30 permit tcp destination-port eq 7070

I had to edit the attribute H3C-Web-URL (removed allow tagging). After this change was able see the redirection URL being pushed just fine, as you can see below:

Now, even still if the user opens a browser and types any web-site, the user is still not getting redirected to the above URL on the switch?

Any insights if I am missing out any configuration on the switch?

I am using this little ACL to test out the above use case:

Was able to get the redirection working using HP switch, it was finally the issue with the ACL that we were using.
The ACL had to be tweaked to specifically allow ports 443 and 80 towards and resolved issue.
Here is the ACL that I used for this purpose:

rule 0 permit tcp destination <ISE Server> 0 destination-port eq 443
rule 5 permit tcp destination <ISE Server> 0 destination-port eq www
rule 10 permit udp destination-port eq dns
rule 15 permit udp destination-port eq bootps

Now there is another issue that I am facing, when the user clicks on the download agent link, he directed towards a blank page and no download happens.

Hi Dinesh,

Make sure you have the Posture type set to 'Temporal agent' under Posture Policy.

Check this guide here - https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/admin_guide/b_ise_admin_guide_24/b_ise_admin_guide_24_new_chapter_010111.html#Posture_Types

Thanks,

As per the requirement here with client they are not going for a temporal agent for this, since these are going to be corporate machine users.

So, need to make sure that AnyConnect agent is downloaded and posture checks are run

Yes, need open up a TAC case for this one.
