Introduction to ARP
Table Size
Configuration

You can manually configure the maximum numbers of ARP entries (that is, the
sizes of ARP tables) on an Switch 8800 Family routing switch to meet your actual
needs.

The following table lists the specifications and numbers of ARP entries on variious
models.

CAUTION:

■

After the configuration of a short static ARP entry, the system will include it
into the number of non-aggregated ARP entries. If the short static ARP entry is
resolved from a non-aggregated port, the number of non-aggregated ARP
entries will remain unchanged; if the short static ARP entry is resolved from an
aggregated port, it will be deducted from the number of non-aggregated ARP
entries and included into the number of aggregation ARP entries.
