Packet Inspection Filter
The Packet Inspection Filter (PIF) allows configuration of rate limits for broadcast neighbor
discovery (IPv4 Address Resolution Protocol and IPv6 Neighbor Solicit) packets. The
PIF rate limiting threshold affects the following services:
• ARP Broadcast Filter for Mesh links (see
Optional Mesh Configuration Features
on
page 303)
• Proxy ARP for WLAN interfaces (see
on page 160 under Creating
a WLAN)
• Proxy ARP for Tunneled WLANs (see
on page 84)
When Proxy ARP or ARP Broadcast Filter services are enabled, the AP attempts to
reduce neighbor discovery traffic over the air by replacing broadcast messages with
unicast messages for known hosts. When these packets are received for an unknown
host, the Packet Inspection Filter supplements this functionality by limiting the rate at
which these packets are delivered.

Ethernet Port Redundancy
Ethernet Port Redundancy (or NIC bonding) provides a method for aggregating
Zonedirector network interfaces into a single logical "bonded" interface.
With port redundancy enabled, one of the two network interfaces will be in active state
while the other is in standby state. When the active interface physical link is down and
the standby interface physical link is up, the two interfaces will fail over within 3 seconds,
