DHCP Bug in OS 5.22?

bean3178 · Mon Jan 28, 2013 5:48 pm

We have a RB2011UAS-2HnD-IN running 5.22. We have a bridge setup to bridge wlan1 and some physical ports. We have a DHCP server configured on that bridge. Cisco phones connected to the physical ports get a DHCP address fine along with TFTP option 150 and register to our phone system.

We are having a problem with 2 different models of wireless Cisco phones. They associate with the AP fine. But, one model never gets a DHCP address and another model is assigned the NETWORK address of the voice subnet.

If we move the DHCP scope to the Cisco switch that is trunked into the Mikrotik, then both the wired and wireless phones work fine. So, this leads me to believe that there are issues with the Mikrotik DHCP server.
