Where do I change my MTU size to come up the same as the VM one during IPL/BOOTING of 
the Linux system. I have done a manual ifconfig on Linux to 1500 and changed my VM 
site to 1500 the errors keep on increasing.

iucv0     Link encap:Serial Line IP
          inet addr:147.110.49.130  P-t-P:147.110.49.133  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
          RX packets:49 errors:0 dropped:0 overruns:0 frame:0
          TX packets:49 errors:30 dropped:30 overruns:0 carrier:30
          collisions:0 txqueuelen:217
          RX bytes:4686 (4.5 Kb)  TX bytes:6419 (6.2 Kb)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:38 errors:0 dropped:0 overruns:0 frame:0
          TX packets:38 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:3264 (3.1 Kb)  TX bytes:3264 (3.1 Kb) 

Please assist.
Thanx you all in advance.
