Hi, Thanks !!

It was set to 100mbps but was not full duplex
we did it and it went through fine.

PS: le0 dosent support full duplex mode... only hme0 or qfe0 ...

The following may prove useful in support of this:

How to force the HME card to work at 100mb (full-duplex).

If the auto negotiate does not work, then the 100-MB full-duplex mode
can be forced to run at 100-MB, Full-Duplex using the following:

Please try (if using /etc/rc2.d/S99...)

        ndd -set /dev/hme instance 0
        ndd -set /dev/hme adv_100T4_cap 0
        ndd -set /dev/hme adv_100fdx_cap 1
        ndd -set /dev/hme adv_100hdx_cap 0
        ndd -set /dev/hme adv_10fdx_cap 0
        ndd -set /dev/hme adv_10hdx_cap 0
        ndd -set /dev/hme adv_autoneg_cap 0

        or (if using /etc/system)

        set hme:hme_adv_autoneg_cap=0
        set hme:hme_adv_100T4_cap=0
        set hme:hme_adv_100fdx_cap=1
        set hme:hme_adv_100hdx_cap=0
        set hme:hme_adv_10fdx_cap=0
        set hme:hme_adv_10hdx_cap=0

Note that the order does make a difference.
The link is re-negotiated when the interface is
ifconfig'ed up or when ndd ndd adv_autoneg_cap command is executed.


How to force the HME card to work at 10mb (full-duplex).

The section "10FDX" includes how to force the HME card to work at 10 MB
(full-duplex). You can either put the commands in the /etc/system file
or in a startup script -- i.e. /etc/rc2.d/S99hme_config. Another way
is to make the changes from the command line -- using the "ndd" command
the syntax below. But it is better to put the commands in /etc/system or a
startup script to preserve the environment accross reboots.

10FDX only


     set hme:hme_adv_autoneg_cap=0
     set hme:hme_adv_100T4_cap=0
     set hme:hme_adv_100fdx_cap=0
     set hme:hme_adv_100hdx_cap=0
     set hme:hme_adv_10fdx_cap=1
     set hme:hme_adv_10hdx_cap=0

     ndd commands

     ndd -set /dev/hme instance 0
     ndd -set /dev/hme adv_100T4_cap 0
     ndd -set /dev/hme adv_100fdx_cap 0
     ndd -set /dev/hme adv_100hdx_cap 0
     ndd -set /dev/hme adv_10fdx_cap 1
     ndd -set /dev/hme adv_10hdx_cap 0
     ndd -set /dev/hme adv_autoneg_cap 0

Is the hme interface running at 10BaseT or 100BaseT

How do you tell if the hme interface is actually linked up at 10 Mbps or 100


# ndd -get /dev/hme link_status
# ndd -get /dev/hme link_speed
# ndd -get /dev/hme link_mode

link_status (read only)
      0 for Link Down
      1 for Link up

link_speed (read only)
      0 for 10 Mbps
      1 for 100 Mbps

link_mode (read only)
      0 for Half-Duplex mode
      1 for Full-Duplex mode
