Problem with built-in LAN

[Alan Casey]

Hi,

I have a k210, and built-in LAN at 10mbps.
When I use this card transferring data is very slow, it takes about 20 seconds to transfer a 50k file using ftp.

I don't have this problem with the Token Ring card in the same box.

I am sure it's not our network.

Any ideas?

Hi Alan,

I am almost certain that you have a speed/duplex mismatch between your K-box and the other end of the same connection at your switch.

You need to hard set the speed/duplex on both the K-box and at the other end. Auto-negotiation is not very reliable.

the core interface on a K series is half-duplex only. it cannot autonegotiate. nor can it operate at 100 Mbit/s. it can only operate at 10 Mbit/s.

so, making sure that the switch isn't trying to do something like full-duplex 10 Mbit/s would be good. make sure the lanadmin statistics are "clean" - collisions are OK, "late collisions" are not, nor are FCS errors and the like.

Hi Alan,

This seems to be problem with network speed setting only. Ensure the correct speed on the switch side and if you find any mismatch in the system side (Autonegotiable), edit /etc/rc.config.d/hpbase100conf file and make the correct entry.

You can use the lanadmin command to view the current speed setting.

eg:
#lanadmin -x 4
where 4 is the NM-ID.

Hope this will help you.
