LAN performance

[Scrivano]

How do i get to check lan config and connection speed on a tru64 system?
Need to know if its configured as 100Btx-FD or 100Btx-HD, etc...

Simptons are slow connections between two servers.

Tks,
Scrivano

Please read through the discussion begun on 10/28 in this conference. It goes into considerable detail regarding the question you have asked.

Basically in Tru64unix v4, the only method for checking speed/duplex is by reviewing the last reboot in the messages file.

In V5 Tru64unix you can use the following command:

hwmgr get attr -cat network -a name -a media_speed -a full_duplex.

To set the speed/duplex mode, the lan_config
utility is recommended and should be placed in /etc/inet.local. See man lan_config.

Only older DEC produced network cards will responds to console settings. All newer cards/drivers such as the DE60X and gigabit cards ignore console settings.

You can also check netstat -i. If this display does not record ierrs or oerrs for a particular NIC, then you more than likely have a match between switch and NIC for speed and duplex mode. If any NIC lists collisions, it is a good bet that it is operating in half duplex mode. Errors may also indicate a mismatch for speed/duplex.
