S9306 directe connects S3552F-EA device, use VlANIF to interconnect but not interworking.
1. Check device configuration:
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.
1. Configuration reason
2. Line reason
3. Negotiation reason
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.
