I have AIX 5.2 installed on p5-615 with 2 ethernet adapters. Once for 10/100 network and other for 10/100/1000 network.
We just upgrade our switch to gigabit network and try to use gigabit adapter.
Unforenately, the switch detect it as 100 connection, even lost.

How do i fix this problem?so, my adapter operate properly and the switch detect it as gigabit adapter.

hereis my config
$ oslevel -r
5200-00

$ lsdev |grep ent
ent0 Available 1L-08 10/100 Mbps Ethernet PCI Adapter II (1410ff01)
ent1 Available 1j-08 10/100/1000 Base-TX PCI-X Adapter (14106902)

$ ifconfig -a
en0: <UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST ,GROUPRT,64BIT,CHECKSUM_OFFLOAD,PSEG,CHAIN>
en1: <UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST ,GROUPRT,64BIT,CHECKSUM_OFFLOAD,PSEG,CHAIN>
lo0: <UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,G ROUPRT,64BIT>

what media speed is your ent1 adapter set to? run an lsattr -El ent1 and make sure that the media speed is not set to 100_Full_Duplex. If it is set to Auto_Negotiate, you may have to change it to 1000_Full_Duplex

I do not believe setting the adapter to 1000_Full_duplex is an option in 5.2. If you want gig speed, ensure that the speed and duplex is set to Auto negotiate on your adapter and your switch port.

Or set the adapter to auto and the switch to 1Gb.

From about 5.2 ML04 (or 5) I think you can set the adapter to 1 Gb

Exactly, Hess. There are no 1000 option, only 10 or 100 option available. I've set to auto_negotiation and my switch ready for gigabit, but it still not working. Any other solution?

$ lsattr -El ent1 |grep speed
media_speed Auto_Negotiation Media speed True

What does "entstat ent1" say?
