If the uplink gateway has the correct IP address in the correct VLAN, go to step 10.
If the uplink gateway does not have the correct IP address in the correct VLAN,
reconfigure and repeat step 2.
Is there a static ARP entry using the IP of the downlink
device or uplink gateway?
Static ARP prevents the learning of ARP entries for another MAC address or port. If
the switch cannot update its ARP table for this IP address, then packets are sent to a
wrong destination causing failed communication.
If the switch does not have any static ARP for the downlink or uplink devices, go to
step 11.
If the switch has an incorrect static ARP entry for the downlink or uplink devices,
reconfigure and repeat step 2.
