Hi,
I have a requirement that we're trying to fulfill which is to raise the PMTU value from 1500 to 9000 on my HP-UX 11.23 System. We thought that we had done this by adjusting the necessary values in /etc/rc.config.d/hpigelanconf. We rebooted and we're realizing the settings did not take place. Attached is a sample of our hpigelanconf file. Could anyone have any other recommendations on what we may be missing here?
Thanks in advance,
KPS

Shalom,
This is a network parameter manipulated by the ndd command.
Permanent changes are made in /etc/rc.config.d/nddconf
This is a rather radical change and I don't know if it will be permitted.
The man page provides the details on what you can do and not do.
ndd -get network_device parameter
ndd -set network_device parameter value
ndd -h sup[ported]
ndd -h unsup[ported]
ndd -h [parameter]
ndd -c

Re: PMTU Size Adjustment
KPS,
be carefull to change MTU size on your ethernet . you must check to your catalyst that you used, it must configured before. to make your permanent changes, check the type of your ethernet (ioscan -nfkClan), igelan or iether? if your ethernet is igelan, you must change the value in /etc/rc.config.d/hpigelanconf.
hopes can help!
