rx4640: how to force the LAN console port speed to 100 Mb/s FD

[CAS_2]

Hi

Is it possible to set the speed of the LAN console port of a rx4640 server to 100 Mb/s Full-Duplex ?

Hi,

run

# lanscan

to find all your LAN cards. In the output you'll find a column "CrdIn#". Use this value with lanadmin, e.g.

# lanadmin -x 0

and you will get this:

Current Speed = 100 Full-Duplex Auto-Negotiation-ON

This is the current speed. Set the new value:

# lanadmin -X 100FD 0

and check the result.

I remembered a discussion on this topic a while ago. Here is the thread. I hope it helps

rx4640 guides show Management Processor LAN port is 10/100 Mbps. But LC command (LAN Config) from Management Processor CLI offers two options only: autonegotiation or 10 Mbps.



Enter parameter(s) to change, A to modify All, or [Q] to Quit: l
l

For each parameter, enter:
New value, or
to retain the current value, or
DEFAULT to set the default value, or
Q to Quit


Link State:
Current -> A - Auto Negotiate (default)
T - 10BaseT
Modifying this parameter will cause all present LAN and Web
connections to be dropped.

Enter new value, or Q to Quit:




Is there any way to force to 100 Mbps Full-Duplex ?

I didn't notice the LAN >>console<< port.

Please check your network switch for the result of auto-neg. You may also have a look at the connector: amber/yellow is 10, green is 100.

I may be confused, but I believe that the firmware limits the card to 10 Mbps HD.

Hi,

There is no other way to force 100Mbps FD operation for MP LAN port if the option is not provided by the firmware.

As you can see there are only two options. You need to ensure either option same between the MP lan port and switch port.
Saying that if it Auto-negotiate, then keep it same across the channel (port and switch port). If you select 10BaseT , then it will operate in 10Mbps HD mode and same should be ensured across the channel.

If I recall correctly, 100BaseT option was given in Mid-range and high integrity & 9000 end servers. Sometime back, they were locked to use 10Mbps through firmware. Now it seems that 100Mbps mode is re-enabled for mid/high Integrity servers.

In the latest firmware for entry-level integrity servers like rx4640 etc. I don't see support being added for 100BaseT. So you have oply those two options.
