12-250 w/ Mimosa

[cnagle75]

Hi,
We recently enabled VLAN's across the network and on all but 1 switch, when reviewing the MAC table, the IP address shows with the corresponding MAC of the hardware. On one specific switch, the LAST IP shows "unknown" for all Mimosa gear (access points and CPE's) and some client routers.

Switch is a 12-250
Firmware is 1.5.8

The config is exactly the same across all switches.
All equipment is accessible via IP address issued by DHCP
All client routers show up in the MAC table with the corresponding IP address
All traffic is passing correctly

Curious to know if anyone else has experienced this and if so, were you able to resolve it?
