•ARP

For Layer 3 tracking to function, the data must be RFC-1490 encapsulated data or RFC-2427 encapsulated data (RFC-2427 superseded RFC-1490). For an IP packet to be recognized, it must be carried by an RFC-2427 IP header or an RFC-2427 SNAP header for bridged ethernet. If the SNAP header is carrying a bridged ethernet packet, the MAC header is examined for the protocol type. SNAP headers are also examined for IPX and ARP traffic.

The ARP option actually tracks inverse ARP where addresses are resolved across the WAN link. SNA traffic is recognized by its RFC-2427 header.

Information is gathered for the two protocol types you choose and is displayed with P1 representing information for PROTOCOL 1 and P2 representing information for PROTOCOL 2.

There are four different views of the Layer 3 Statistics:

•Network Port, View by Interval

•Network Port, View by Day

•DLCI, View by Interval

•DLCI, View by Day

Descriptions of the fields found in these menus follow. Field descriptions are the same for both protocol selections, so “x” represents the protocol number.

Px Type (current)

The protocol type currently selected in the CONFIGURATION menu is displayed in this field.

Interval Remaining

Number of seconds remaining in the current timed interval.
