ALTER Command
IOPORTNAME LIF-name.filter-protocol
LIF-name displays the name of the logical interface (LIF). An Ethernet or token-
ring LIF name usually takes the form L0xx.
filter-protocol displays the filter protocol name that supports the frame type
of the NetWare network. Table 3-1
on page 3-9 lists each frame type and
corresponding filter protocol along with the LAN type they support.
IPXMAXSOCKETS integer
is the number of IPX sockets allowed open simultaneously. The recommended value
is 32 + n, where n is the number of IPX sockets required by IPX applications. The
32 sockets are used by the NCP protocol of NonStop™ IPX/SPX. The range is 50 to
2000 sockets, and the default is 50. (Since 32 of the sockets are used by the NCP
protocol, only 18 sockets are available when using the default value of 50.)
QIOLIMIT integer
SPXKEEPALIVETIMER integer
is an integer between 1 and 60 that represents the number of minutes SPX waits
before pinging an SPX connection to verify the existence of a remote SPX endpoint.
(A ping tests the reachability of another machine on the network.) SPX issues an
initial ping to an SPX connection that has not received a packet for the configured
SPXKEEPALIVETIMER value. If the remote endpoint does not respond to the
initial ping, SPX sends an additional four pings at one-minute intervals. An
unresponsive SPX connection is disconnected after the fifth ping. The default is five
minutes.
For example, if SPXKEEPALIVETIMER is set to 7, SPX sends up to five pings at
one-minute intervals if an SPX connection has not received a packet for seven
minutes.
SPXMAXBINDS integer
is the number of concurrent, explicit binds to this particular IPXPROTO process. An
explicit bind is the result of a socket BIND call by an SPX application, typically
caused by a server process listening on the socket. The bind is terminated when the
application closes the socket. Set SPXMAXBINDS to a value equal to or greater
than the upper bound on the expected number of concurrent binds. The range is 10
to 500 binds; the default is 25.
Note. QIOLIMIT, an attribute of QIO accounting, should be ignored. QIO accounting is not
supported for G-series releases of NonStop™ IPX/SPX.
Note. SPXMAXBINDS significantly affects memory usage; you should set this value as low as
possible.
