I can't say I've ever seen a hub that supports FDX. Just opt for a switch or 2 depending on testing you are performing. (Note that not all switches will support VLAN routing...managed switches will have this functionality, but do check specification). Most switches will auto sense the speed and duplex settings.

One other point is that I have seen issues with auto-negotiate set on Solaris hosts when connected to Cisco switches that are also set to auto-negotiate...the whole thing just gets confused. I have found it is thus best practice to hard set your hosts to 100 FDX if you know it is available.

ibprintswitch

IBPRINTSWITCH(8)						OpenIB Diagnostics						  IBPRINTSWITCH(8)

NAME

       ibprintswitch.pl - print either the switch specified or a list of switches from the ibnetdiscover output

SYNOPSIS

       ibprintswitch.pl [-R -l -C <ca_name> -P <ca_port>] [<switch_guid|switch_name>]

DESCRIPTION

       Faster  than greping/viewing with an editor the output of ibnetdiscover, ibprintswitch.pl will parse out and print either the switch infor-
       mation for the switch specified or a list of all the switches found in the subnet.  In addition, it will crudely parse on the node descrip-
       tion information and if found report all the information for an entire chasis if the description information is consistent.

       Finally,  ibprintswitch.pl  will  also  reuse the cached ibnetdiscover output from some of the other diag tools which makes it a bit faster
       than running ibnetdiscover from scratch.

OPTIONS

       -l     List the switches (simply a wrapper for ibswitches).

       -R     Recalculate the ibnetdiscover information, ie do not use the cached information.	This option is slower but should be  used  if  the
	      diag tools have not been used for some time or if there are other reasons to believe that the fabric has changed.

       -C <ca_name>    use the specified ca_name for the search.

       -P <ca_port>    use the specified ca_port for the search.
