Handling Process

1. Check device configuration:
interface GigabitEthernet1/0/42                                                
description To_S3552F-EA_G1/7/8                                    
port link-type trunk                                                          
undo port trunk allow-pass vlan 1                                             
port trunk allow-pass vlan 1015 
arp anti-attack check user-bind enable                                        
undo negotiation auto

It find that S9306 device port configured arp anti-attack check user-bind enable command, but static ARP.

2. Delete arp anti-attack check user-bind enable command, the problem is solved.
Root Cause
1. Configuration reason
2. Line reason
3. Negotiation reason
Suggestions
The command means arp packet that pass through port should be checked, packet who has no table will not pass.
The command is used by combining arp binding or user-bind, creating table is static arp, others are defined to legal, so the business is not interworking.
