SG350 DHCP snooping DB not updating

Hello all,

 

   recently we run into an issue. I am managing some retail shops, where I have few switches (SG350, SG350P) some Unifi APs and brand new Zebra barcode scanners. Everything works fine unless the guys roam with the Zebras from one AP to another. In that case the barcode reader cannot reach the server and itself is unreachable for about 5 minutes.

 

   After some troubleshooting we found out that after roaming the MAC/ARP table is updated properly (For example gi1->gi2) , however, DHCP snooping DB is not, in DHCP snooping DB remains the old port (gi1).

 

Is anyone facing same issue?

 

Tomas
