Usage Information In Dell Networking OS versions prior to 8.3.1.0, if a gratuitous ARP is received some
time after an ARP request is sent, only RP2 installs the ARP information. For example:
1 At time t=0, Dell Networking OS sends an ARP request for IP A.B.C.D.
2 At time t=1, Dell Networking OS receives an ARP request for IP A.B.C.D.
3 At time t=2, Dell Networking OS installs an ARP entry for A.B.C.D only on RP2.
Beginning with Dell Networking OS version 8.3.1.0, when a gratuitous ARP is received,
Dell Networking OS installs an ARP entry on all three CPUs.
