the product is no longer active in Red Hat Bugzilla.
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.

Definitely not a big issue, but according to IEEE802, both semicolon (00:11:22:33:44:55) and dashed formats (00-11-22-33-44-55) are valid. So perhaps nmcli's profile editor can allow setting the MAC in dashed format as well, even if it get's converted to ':' immediately.
Sounds like a quick win. Since the standard library functions like ether_aton() don't handle "-" nmcli would probably just quickly search/replace "-" to ":" if the first attempt at ether_aton() failed.

[PATCH] util: allow hyphens in MAC notation - nm_utils_hwaddr_aton_len()
The patch allows accepting hyphens (-) in MAC address string representation in nm_utils_hwaddr_aton(_len) function. nmcli uses the functions, so both 'add' and 'edit' nmcli commands will accept such MACs.

Actually, nmcli doesn't use ether_aton() any more. Instead, it makes use of libnm-util nm_utils_hwaddr_aton() and nm_utils_hwaddr_atoba() functions. So I updated the libnm-util's code.
ether_aton() is used on several places in NM, mainly for reading MAC from ifcfg. I'm not sure if we want to allow hyphens there too.
