I am attempting to change the speed and duplex settings on a single interface on a bge card on an m3000 SPARC server. Currently the settings are as follows:
I would like to change the bge1 interface to full duplex permanently. I read that I could make changes to the /platform/sun4u/kernel/drv/bge.conf file to make this permanent, however all of our attempts have not yielded the expected results.
Additional Information:
Any assistance would be greatly appreciated.

Hi All
I've been having a lot of errors logged on the Cisco Catalyst (4000 series) which one of my Solaris servers is patched into. I have a feeling they are duplex related, but I'm a bit stuck as to how to confirm that.
How do I:
1. Check the duplex settings on my eri0 card?
2. Set the... (3 Replies)

I had added this to the /etc/system file to make to setting permenant So it would be set correctly on reboot.

Hi there
We have a bit of a debate going here over what the prefered method is for setting 1000/Full on e1000g or nge interfaces is.
As you aware the Solaris configration files for nge and e1000g dont allow you to "fix" 1000/Full but instead allow you to set auto-negotiate to ON but only... (1 Reply)

Hi,
In UNIX, it's very easy to find the duplex speed. But in Windows, is there a easy way to find the duplex speed? I can't go to over 100 servers to find this out, I was wondering if I run one command to do this?
Please advice. (2 Replies)
Hi,
How to find whether the server is running with half duplex or full duplex. I tried with the following command ndd -get /dev/ but am not getting any output,. Is the command correct?
Also let me know how to change from half to full duplex. (1 Reply)

rge(7D) Devices rge(7D)NAME
rge - Realtek Gigabit/Fast Ethernet Network Adapter driver
SYNOPSIS
/dev/rge
DESCRIPTION
The rge Gigabit/Fast Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link
Provider Interface, dlpi(7P), on the Realtek Gigabit/Fast Ethernet Network Adapter.
The rge driver functions includes controller initialization, frame transmit and receive, promiscuous and multicast support, and error
recovery and reporting.
APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/rge is used to access all Realtek Gigabit/Fast Ethernet devices installed within the system.
The rge driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of rge instances and for rge
instances to be aggregated. See dladm(1M) for more details.
The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ are as follows:
o Maximum SDU (with jumbo frame) is 7000.
o Minimum SDU is 0.
o DSLAP address length is 8 bytes.
o MAC type is DL_ETHER.
o SAP length value is -2, meaning the physical address component is followed immediately by a 2-byte sap component within the
DLSAP address.
o Broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream.
CONFIGURATION
By default, the rge driver performs auto-negotiation to select the link speed and mode. Link speed and mode can be any one of the follow-
ing:
o 1000 Mbps, full-duplex
o 100 Mbps, full-duplex
o 100 Mbps, half-duplex
o 10 Mbps, full-duplex
o 10 Mbps, half-duplex
Alternatively, you can set the capabilities advertised by the rge device using ndd(1M). The driver supports a number of parameters whose
names begin with adv_. Each of these parameters contains a boolean value that determines if the device advertises that mode of operation.
The adv_pause_cap indicates if half/full duplex pause is advertised to link partner. You can set adv_asym_pause_cap to advertise to the
link partner that asymmetric pause is desired.
For example, to prevent the device 'rge2' from advertising gigabit capabilities, enter (as super-user):
# ndd -set /dev/rge2 adv_1000fdx_cap 0
All capabilities default to enabled. Note that changing any capability parameter causes the link to go down while the link partners renego-
tiate the link speed/duplex using the newly changed capabilities.
You can find the current parameter settings by using ndd -get. In addition, the driver exports the current state, speed, duplex setting,
and working mode of the link via ndd parameters (these are read only and may not be changed). For example, to check link state of device
rge0:
# ndd -get /dev/rge0 link_status
1
# ndd -get /dev/rge0 link_speed
100
# ndd -get /dev/rge0 link_duplex
2
The output above indicates that the link is up and running at 100Mbps full-duplex. In addition, the driver exports its working mode by
loop_mode. If it is set to 0, the loopback mode is disabled.
