Configuring AppleTalk on an Access Server
8-4 Managing AppleTalk
The default value for
n
is the number of access server asynchronous ports divided by
8. For instance, the default cache size on a 16 port access server would be 2.
The DEFINE APPLETALK ADDRESS CACHE command lets the access server
manager trade off address use versus the probability of simultaneous Appletalk session
requests.
•
If the value of
n
is set too high, the access server can acquire too many addresses,
exhausting the supply available for the rest of the network.
•
The access server serializes address acquisition attempts, which typically require
about 2 seconds each. If the access server pre-acquires too few addresses (the
value of
n
is too low), some client AppleTalk session initiation attempts may fail
if too many arrive at once. When this happens, the access server may not have
enough addresses to assign to all the new sessions.
