Appendix A: Troubleshooting 802.1X - HP 635n - JetDirect IPv6/IPsec Print Server How To Use Manual

Starting with V.38.05 and later firmware, HP Jetdirect has a new capability to log 802.1X

information to the Security Page. In the control panel menu for Jetdirect, which starts as "Embedded

Jetdirect" or "EIO Jetdirect", enter the menu structure and then go to "Information", then "Print Security

Page". A security page will be printed similar to the ones shown in this section. If your HP Jetdirect

firmware doesn't support the 802.1X logging or is installed in a Digital Sender only product, we'll

need to get a network trace to troubleshoot. Network switches that support 802.1X are fairly

sophisticated and they often support the ability to "mirror" a port for network tracing.

We are going to go through a series of 802.1X conditions and show both the 802.1X log and the

network trace, which has been filtered to look for only "EAP" packets.

EAP-TLS Success

We need to see what a successful 802.1X session looks like first. Here is the 802.1X log:

At the bottom of the page we can see the log that shows the activity of the 802.1X supplicant on

Jetdirect. However, this security page provides a great snapshot of the configuration of HP Jetdirect

for 802.1X and Certificates.

Next, we can see what a network trace looks like for an EAP-TLS success.
