Fixed In Version: NetworkManager-1.39.3-1.el8
Doc Type: Enhancement
Doc Text:
.NetworkManger now stores DHCP lease information in the `/run/NetworkManager/devices/` directory NetworkManager now stores lease information from the DHCP server in the `/run/NetworkManager/devices/` directory. Previously, the file-based API was not available and this information was only visible in the output of the `nmcli -f all devices show DEVICE` command. With this enhancement, other utilities and scripts can access DHCP options without calling `nmcli`.

Description Nate 2021-03-25 13:32:42 UTC
Description of problem:
NetowrkManager does not log or display information about what DHCP server granted its lease.  This information was provided by dhclient when it was the standard.

Version-Release number of selected component (if applicable):
RHEL 8.3, NetworkManager-1.26.0-13.el8_3.src.rpm

How reproducible:
Every Time

Steps to Reproduce:
Attain DHCP lease
Attempt to discern what server provided said lease using nmcli conn show <interface> OR view stored lease file

Actual results:
No granting dhcp server is listed in dhcp lease options.
No log in system journal or syslog shows this information either.

Expected results:
This information should be available from one, or several, of the sources listed above.
