Overview
The software places an entry from the static ARP table into the ARP cache when the entry interface
comes up.
Here is an example of a static ARP entry.
Index

Each entry lists the information you specified when you created the entry.
To display ARP entries, refer to the following sections:
•
•
•
To configure other ARP parameters, refer to the following sections:
•
To increase the size of the ARP cache and static ARP table, refer to the following:

•
IP route table
The IP route table contains paths to IP destinations.
NOTE
Layer 2 Switches do not have an IP route table. A Layer 2 Switch sends all packets addressed to
another subnet to the default gateway, which you specify when you configure the basic IP
information on the Layer 2 Switch.
The IP route table can receive the paths from the following sources:
•
•
•
•
•
The IP route table contains the best path to a destination:

Here is an example of an entry in the IP route table.

Static entries, "Changing the maximum number of entries the static ARP table can hold"

size.
A directly-connected destination, which means there are no router hops to the destination
A static IP route, which is a user-configured route
A route learned through RIP
A route learned through OSPF
A route learned through BGP4
When the software receives paths from more than one of the sources listed above, the
software compares the administrative distance of each path and selects the path with the
lowest administrative distance. The administrative distance is a protocol-independent value
from 1 through 255.
When the software receives two or more best paths from the same source and the paths have
the same metric (cost), the software can load share traffic among the paths based on
destination host or network address (based on the configuration and the Layer 3 Switch
model).
