Hello,
does anyone know how to set the IP config to auto detect?
If i take a look to the switch i only see 100MB Full duplex and i can't find any commando to set the switch to auto detect...

Hi,

On Brocade Switches, it can be configured using the command
#ifmodeset

Ex:
switch:admin> ifmodeset eth0
Exercise care when using this command. Forcing the link to
an operating mode not supported by the network equipment to
which it is attached may result in an inability to
communicate with the system through its ethernet interface.
It is recommended that you only use this command from the
serial console port

Are you sure you really want to do this? (yes, y, no, n): [no] y
Proceed with caution.
Auto-negotiate (yes, y, no, n): [no] y
Advertise 100 Mbps / Full Duplex (yes, y, no, n): [yes] y
Advertise 100 Mbps / Half Duplex (yes, y, no, n): [yes] y
Advertise 10 Mbps / Full Duplex (yes, y, no, n): [yes] y
Advertise 10 Mbps / Half Duplex (yes, y, no, n): [yes] y
Committing configuration...done.

Rgds,
Prabhu

100/Full is your friend. Auto-detect is not.

;o)

but yes, ifmodeset should do the trick.

You should also be able toset it in the Admin Web GUI.

By default, I do run this stuff with auto-*negotiation*
and had good experience with it for a number of years
(yes, I have seen problems with old, old 1 GBit switches).
