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.
