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 P
P2 representing information for P
There are four different views of the Layer 3 Statistics:

Descriptions of the fields found in these menus follow. Field

represents the protocol number.

Number of seconds remaining in the current timed interval.

changed (see Protocols 1 and 2 on page 9-4), the new selection is not
accepted by the DSU IQ until the end of the current timed interval.
For example, if the DSU IQ is configured for 5-minute timed
intervals, and the P
