Parameter: Max Forwarding Table Size
Path: Configuration Manager > Protocols > IP > Interfaces
Default: 128 entries
Options: 64-entry minimum; no maximum
Function: Specifies the maximum number of entries allowed in the forwarding table at
one time.
Instructions: Specify a forwarding table size for each interface. This parameter controls the
number of destinations that are cached in the forwarding table on this receiving
interface. When this interface receives an IP packet, the router looks up the
destination in the forwarding table. Therefore, an interface that receives
packets that are destined for a large number of different destinations may
benefit from a larger forwarding table. The larger the number of entries, the
more likely it is that the destination will already be in the forwarding table and
the faster the route lookups will be for those destinations. Configuring a
forwarding table size that is larger than necessary reduces the total amount of
memory usable by other applications. Configuring a routing table too small can
affect overall router performance. A check of the number of cache hits and
misses will help determine the optimal size of the forwarding table. For
debugging purposes, if you see the wfIpInterfaceCacheMisses statistic going
up at an alarming rate, you should consider increasing the table size. However,
an occasional cache miss does not warrant an increase in table size.
