Could not set ip_pmtu_strategy to 2

[JI HUI]

HP-UX 11.0:
Command:
ndd -set /dev/ip ip_pmtu_strategy 2
Output:
operation failed. Invalid argument.

Could set to 1 and 2 is shown as valid value in the man page.

Seems PHNE-24715 make 2 obsolate. But it was not installed.

Please advise

if you do a check for that patch at the fileset level you may find it is installed.

swlist -l fileset | grep PHNE_

it could have been installed as part of another bundle or a dependancy of something else.

What I know is ..

PHNE_20735 is the last patch having ip_pmtu_strategy=2.

PHNE_21767 obsoleted the value 2 and defaulted it to 1.

Hence the supported value of ip_pmtu_strategy are 0 and 1.

Thank you for your help.

Is 3 a acceptable value. I have seen it somewhere that by setting ip_pmtu_strategy to 3, the MTU size could be configured.
