We are running v5r4 and system is a 520.

Currently our Iseries is set to 10M for a connection as seen below:

Line speed . . . . . . . . . . . . :   LINESPEED   10M  
Current line speed . . . . .. . :                       10M  
Duplex . . . . . . . . . . .... . . . :   DUPLEX      *HALF

I am interested in instructions on how to change this to 100 or 1GB as im pretty sure our iseries supports it.  The reason I am told it is set to 10 was an old switch which has been replaced was a 10MB switch.

WRKLIND LIND(*ELAN)   - is this the only place that needs to be configured?  this is what shows:

ETHLINE     *ELAN       Ethernet Line Description
RS99BGCAPP  *ELAN                                
RS99BGCBPP  *ELAN                                

We have 2x IXA's and here are their values:

Ethernet standard  . . . . . . . . :   ETHSTD        *ALL
Line speed . . . . . . . . . . . . . . :   LINESPEED   1G  
Current line speed . . . . . . . . :                        1G  
Duplex . . . . . . . . . . . . . . .. . . :   DUPLEX        *FULL

Also do I need/want the duplex set to half or full?  Will i need to restart any subsystems or devices when I make the change or simply vary off / vary back on the device?  Any details would be much appreciated!  Thanks in advance.

Line description is the only place you need to change it.  

Use *HALF connecting to a hub, *FULL if connecting to a switch or directly to a gateway.

Varying off the line, making the change, and varying it back on should do the trick.  It is possible that poorly written communications applications could fail and need to be restarted.  If you are concerned that this is the case, wait for an appropriate maintenance window when jobs are shut down (maybe right before or after backups).  

Be aware that you will interrupt communications sessions that traverse the line, so pick a safe time and notify users.
