Did you connect the mgmt port to the front ports ?
mgmt port is down
we have different nodes connected in different vlans, the image in use is 15.1.3.4

I would check for a physical loop with ELRP on all vlans.
sh elrp

ELRP Standalone Client: Enabled

Number of ELRP sessions: 2
Number of ELRP pkts transmitted: 5963055
Number of ELRP pkts received: 0

Yes, although part of it something in the network forwarding the general query with the original mac address as source which is something that normally does not happen.
use elrp one shot to test for a loop on other VLANS. Unless you only have 2 VLANS.
