Displays distributed IP ARP statistics for all slots.
When distributed IP ARP mode is active on a switch, this command allows you to view how many IP ARP entries are assigned to the ports on supported I/O modules. To turn on distributed IP ARP mode, use the configure iparp distributed-mode command.
You can use the information from this show command to determine if the total entries in use is close to or equal to the total entries supported by the I/O module hardware. When the total entries in use reaches the hardware limit, new entries must replace existing entries, and IP forwarding temporarily takes place using the slow path through software, rather than the fast path through hardware.
If the total entries in use gets close to the maximum entries supported by the hardware, consider moving IP hosts to a port or port group that is not so close to the hardware limit.
The following example displays distributed IP ARP statistics for all slots:
