rx8620 mp lan problem

[Royal Madison]

I am trying to enable autonegotiate on the
mp lan settings for an rx8620, but everytime I use LC command to modify the mp lan settings enabling/disabling the autonegotiate is not an option. Currently the autonegotiate is set to disabled. Has anyone seen this before?

Hi,

I have seen the MP causing strange problems if set to auto-negotiate or anything other than 10Mb.

So I would guess that the latest firmware disables this autneg settings.

With regards,
Mohan.

The MP LAN speed is set to 10MBit/s HD fix by default now. Newer firmware versions doesn't support other settings.

quote
(taken from firmware 3.3 release notes, same for 4.0 - see patch PF_COLYEIG0330 on ITRC):


* To prevent MP hangs the MP's LAN speed has been locked to
10BT (default = half duplex). There are no longer MP
options to select Auto or 100BT. The net MP throughput
will not dramatically decrease, but reliability is improved
in high console traffic environments. After updating the
firmware (MP A.06.012), if you experience problems
accessing the MP via the MP LAN, ensure that both the MP
and the switch/network which the MP is connected to are set
to 10BT Half Duplex.

You guys were correct I cannot change the mp lan settings thanks to the newer firmware, however, I just used another cable with a different ip address and everything worked fine. It turns out it was the cable all along. Thanks everybody for the input.

What does it mean:

Everything works fine.

10 or 100 MBit/s???

Even if it slows down your MP network connection you should consider to go to a current firmware level to make your system more reliable.
