•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superseded RFC-1490).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.
Information is gathered for the two protocol types you choose and
is displayed with P1 representing information for PROTOCOL 1and
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,ViewbyDay
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)
TheprotocoltypecurrentlyselectedintheCONFIGURATION menu is
displayed in this field.
Interval Remaining
Number of seconds remaining in the current timed interval.
The ARP option actually tracks inverse ARP where addresses are resolved
across the WAN link. SNA traffic is recognized by its RFC-2427 header.
