HI,
Actually I have written the following script that interactively
displays all options available per interface and changes them without
reboot.
-------------------------------------------------------------------------
#!/bin/ksh
##########################################################################
# Written on11/11/04
# Updated on 30 Jan 2005
# Version 1.2
# This script enables changing the speed of a chozen network
interface without a need for reboot
# The script displays a list of the existing ent interfaces with
their current speed and IP setting .
# Once you choose the interfaces,you then choose the desired
speed.
# WARNING: THIS OPERATION WILL CUT OFF ANY APPLETALK/NFS/TCPIP
CONNECTIVITY FOR SEVERAL SECONDS !
# Note: 1.If you are changing the speed of the default interface -
you telnet communication will be cut off for a several
# seconds then it will restore back.
# 2. If you work remotely ,then choose the default interface and
change it's speed to the one which is not
# supported by your swith - the script may stick and leave you with a
disabled network.Then you have to change the
# interface settings localy on your machine
# usage : chent.sh
