RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Mor 2018-03-05 14:48:00 UTC
Created attachment 1404365 [details]

Description of problem:
lldaptool reports strange OID string which causes RHV REST server to report incorrect value since it uses lldptool.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. lldptool -t -n -i <iface> -V mngAddr

Actual results:
See screenshot for OID as is it shown in the console.

Expected results:
Should be parsed differently, as shown in Wireshark (see screenshot).

Comment 4 Mor 2018-03-11 06:47:12 UTC
Update to the bug description: 
lldptool reports the OID as raw bytes from the response, it doesn't parse the value as Wireshark do. OID should be represented by series of numbers of periods.

If you would like to try a patch, I have it here:


I think that provides the requested functionality.  Need to spend some time to format it properly.

Comment 7 Dan Kenigsberg 2018-06-12 09:49:10 UTC
Aaron, we'd love to give it a go. Would you provide mburman with a scratch build to install on his hosts?

Hi Dan, 

Do you still need the z streams 7.5 and 7.6? I'd like to cancel the request if it is no longer required.

No, oVirt is support now only on el8.
