cache-size
value
Cache-size
corresponds to the total number of AppleTalk networks and
nodes that can simultaneously communicate through this router using the
fastpath feature. (Fastpath is a method of precalculating MAC headers to
forward packets more quickly.) The default is 500, which allows up to 500
networks and nodes to simultaneously communicate through the router and
still use fastpath. If the number of networks and nodes becomes greater
than the cache size, the router still forwards the packets, but it does not use
fastpath. Valid values for cache size are: 0 (disable), 100 to 10 000.
Although not recommended, setting the cache-size to zero disables the
fastpath feature and no memory is used for the cache. You need to change
this default only for very large networks. Each cache-size entry uses 36
bytes of memory.
Example:
ap2config>set cache-size 700
net-range
interface# first# last#
Assigns the network range in seed routers using the following:
v interface# - Designates the router interface to operate on.
v first# - Assigns the lowest number of the network range. Legal values are
1 to 65279 (10xFEFF hexadecimal).
v last# - Sets the highest number of the network range. Legal values are
first#
to 65279.
A single numbered network has the same first and last values. A first value
of zero deletes the netrange for the interface and turn the “seeded”
interface into an “unseeded” interface. First# and last# are inclusive in the
network range.
Setting the first value to zero on a Point-to-Point (PPP) interface allows that
interface to operate in ″half-router″ mode. In half-router mode, neither of the
two ends of a PPP network is configured with a network range or a zone list
which reduces the amount of configuration needed. Both routers on a PPP
network must operate in the same mode.
Note: When connecting a 2210 to an IBM 6611 using a PPP interface, set
the 2210 for “half-router” mode which is the
only
mode of operation
supported by the IBM 6611 for AppleTalk communications over a
PPP interface.
Example:
ap2config>set Net-Range 2 43 45
node
interface# node#
Assigns the starting node number for the router. The router will AARP for
this node but if it is already in use, a new node will be chosen. The
following explains each argument that is entered after this command:
v interface# - Designates the router interface to operate on.
v node# - Designates the first attempted node number. Legal values are 1
to 253. A node# value of zero deletes the node number for the interface
and forces the router to choose one at random.
