NOTE
According to the displayed information, the ARP entry learned from GE 1/0/1 is deleted after GE 1/0/1 is
shut down. The aging time of ARP entries learned from GE 1/0/2 becomes 0 after GE1/0/1 is restored and
becomes Up again. When the aging time is 0, the S9300 sends an ARP probe packet for updating ARP
entries.

NOTE
After the ARP entry is updated, the aging time is restored to the default value, 20 minutes.
