48 LAN Card Support | |
For 10.10: The Series T500 (part of the S800 family)
will support up to 48 LAN cards as follows: No changes are needed for the ARPA Transport code. However
it is highly recommended that the administrator run nettune
and adjust the maximum IP interrupt queue parameter ip_intrqmax
to optimize performance. The default value is 50. This feature now expands the maximum number of LAN cards that can
be installed on a T500 system. One utilization of this feature
will be for High Availability, enabling half
the LANs (for example, 16 Ethernet and 4 FDDI interfaces)
while keeping the
remainder as backup in case of failure. This feature
requires additional NIO expander bays for additional LAN cards.
Each expander bay can handle
14 half-height (Ethernet and Token Ring) or 7 full-height (FDDI) cards. LANCONFIG | |
At 10.0, a new feature was added to the lanconfig command to allow
users of TCP/IP over the HP-UX Token Ring/9000 products to selectively
disable or enable the Source Routing feature for 802.5. This produces
additional command-line options. For more information, refer to the
lanconfig(1M) manpage. LANSCAN/LANADMIN/LINKLOOP | |
At HP-UX 10.0, there were a number of changes to the LAN
commands: The display format of lanscan has changed, and there are
new options available.
The lanadmin command replaces the landiag command.
lanadmin has additional features that support setting the
set link speed, station address, and MTU size. The landiag
command exists as a softlink to lanadmin.
The linkloop command requires new parameters to specify the
selected interface.
For more information, refer to the Installing and Administering
LAN/9000 Software manual (98194-90057) and the lanscan(1M),
lanadmin(1M), and linkloop(1M) manpages. NETTUNE | |
At HP-UX 10.0, there was a new command called
nettune that provides an interface for
configuration and tuning of various network parameters.
nettune supports a consistent, reliable, and
secure method for you to use to tune network parameters based on your
performance and configuration needs. nettune allows you to view
(get) or change (set) the value of many networking parameters,
such as the TCP keep-alive timeout value(s), default socket buffer
sizes, or the enabling/disabling of IP forwarding. All users may view
the values of supported configurable network parameters, but only
those with super-user capability can update a parameter. nettune
is command-line driven and has an online help facility that briefly
describes the available configurable values. nettune is in
/usr/contrib/bin, and is not supported by Hewlett-Packard. For more information on nettune, refer to the
nettune(1) manpage in /usr/contrib/man/man1. LAN Product Keywords | |
The keywords in the [78]00 system configuration file for the LAN
products changed at HP-UX 10.0.
Also, dependency features for the LAN products have
changed. The LAN products require DLPI and STREAMS modules
to be present in the kernel. The lan and lan01
keywords are no longer supported. You need to use
lan2 for Series 700 system configuration files,
and lan0, lan1,
lan2, and/or lan3 for
Series 800s.
The DLPI keyword along with STREAMS
keywords (hpstreams,
timod, tirdwr,
clone, strlog,
sad, and echo) must be
included in system configuration files.
If these changes are not made, kernel build failures, either in
conf.c failures or load failures for
vmunix, may occur. For more information, refer to the Installing and
Administering LAN/9000 Software manual (98194-90057) and
the ifconfig(1M) and lanscan(1M) manpages. |
