Can any one help me to find the hp-ux equivalent ndd parameter in solaris

robin_antony — Sat, 22 Aug 2009 15:35:42 GMT

I have seen below are the tcp parameter in solaris

tcp_cwnd_max
tcp_recv_hiwat
tcp_xmit_hiwat
tcp_mss_def_ipv4
tcp_mss_max_ipv4
tcp_mss_min
tcp_recv_hiwat_minmss
tcp_mss_def_ipv6
tcp_mss_max_ipv6
tcp_max_buf
tcp_keepalive_interval
tcp_maxpsz_multiplier
tcp_rexmit_interval_initial
tcp_rexmit_interval_max
tcp_rexmit_interval_min
Can any one help me to find out the equivalent value in hp-ux
Also i require help in setting the value of tcp_cwnd_initial.
HOw this value can be set.

Hi Robin:

You might compare thusly:

# ndd -h supported

...and for detailed information on a specific parameter (by example):

# ndd -h tcp_keepalive_interval

See:

http://docs.hp.com/en/B2355-60130/ndd.1M.html

...JRF...

Hi James

THanks for the reply.
I have gone thru ndd -h and seen most of the above parameters are not present in hp-ux.My aim is to find out the equivalent hp-ux parameter for the above solaris ndd parameters.

Hi All

I have gone thru all those documents whcih you provided.But i am not getting conclusive answer for my query.

My requirement is to match the tcp parameter in solaris with hp-ux.

It might help if you could post a description of what those settings mean under Solaris - is there ndd -h functionality in Solaris to describe them? BTW, at least some of those names appear in HP-UX 11.11 ndd -h output:

$ ndd -h | grep rexmit
tcp_rexmit_interval_initial - Initial value for round trip time-out
tcp_rexmit_interval_initial_lnp - tcp_rexmit_interval_initial for LNP
tcp_rexmit_interval_max - Upper limit for computed round trip timeout
tcp_rexmit_interval_min - Lower limit for computed round trip timeout

$ ndd -h | grep -i mss
multiple of the MSS.
tcp_mss_def - Default MSS to use when none is available
tcp_mss_max - Upper limit on MSS
tcp_mss_min - Lower limit on MSS
tcp_rwin_mss_multiplier - Multiplier applied to the receive window MSS
$ ndd -h | grep -i hiwat
tcp_recv_hiwater_def - Maximum receive window size
tcp_recv_hiwater_max - Upper bound on TCP receive buffer size
tcp_recv_hiwater_lfp - Maximum receive window size for fast links
tcp_recv_hiwater_lnp - Maximum receive window size for slow links
tcp_sth_rcv_hiwat - Sets the flow control high water mark
tcp_xmit_hiwater_def - The amount of unsent data that triggers
tcp_xmit_hiwater_lfp - The amount of unsent data that triggers
tcp_xmit_hiwater_lnp - The amount of unsent data that triggers
tcp_xmit_hiwater_max - Upper bound on TCP send buffer size
udp_recv_hiwater_max - Upper bound on UDP receive buffer size
rawip_recv_hiwater_max - The maximum size of the RAWIP receive buffer
rawip6_recv_hiwat_max - The maximum size of the RAWIPv6 receive buffer
rawip6_recv_hiwat_max - The maximum size of the RAWIPv6 receive buffer
