I have no opinion about this being bad practice or not - IMHO you are right and negotiation can happen at any time. On the other hand, since the times of the 10/100-Adapters Auto Negotiation in IBM Adapters has created far more problems than it solved (if it solved any, that is). I.e. CISCO Switches were for a long time famous for not being able to cope with IBMs adapters in Auto-Negotiation mode and consistently one ended with a port set to 100-Full and a NIC set to 100-Half Duplex (resulting in a bandwidth of ~1kbit/min).

In my experience switching off Auto Negotiation first thing a connection problem arised solved an awful lot of cases - even ones where Auto Negotiation worked for some time, because every microcode update or firmware upgrade might introduce this damn incompatibility again even if it was already solved.

I hope this helps.

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...

How to find the duplex speed on Windows

stacktrace::auto

StackTrace::Auto(3pm)					User Contributed Perl Documentation				     StackTrace::Auto(3pm)

NAME

       StackTrace::Auto - a role for generating stack traces during instantiation

VERSION

       version 0.102080

SYNOPSIS

       First, include StackTrace::Auto in a Moose class...

	 package Some::Class;
	 use Moose;
	 with 'StackTrace::Auto';

       ...then create an object of that class...

	 my $obj = Some::Class->new;

       ...and now you have a stack trace for the object's creation.

	 print $obj->stack_trace->as_string;

ATTRIBUTES

   stack_trace
       This attribute will contain an object representing the stack at the point when the error was generated and thrown.  It must be an object
       performing the "as_string" method.

   stack_trace_class
       This attribute may be provided to use an alternate class for stack traces.  The default is Devel::StackTrace.

       In general, you will not need to think about this attribute.

   stack_trace_args
       This attribute is an arrayref of arguments to pass when building the stack trace.  In general, you will not need to think about it.
