Hi,

Thanks for the script. It saved me some time. To change just the physical NICs I've added an additional if.

for PORT in vsish -e ls /net/portsets/$SWITCH/ports | sed 's/\/$//'
do
        DATA=vsish -e get /net/portsets/$SWITCH/ports/$PORT/status
        echo "$DATA" | grep -q "Physical NIC"
        if [ $? = 0 ];then
                echo "Port: $PORT"
                echo "$DATA" | grep -i "port index:"
                echo "$DATA" | grep -i "clientName:"
                echo "$DATA" | grep -i "clientType:"
                echo "$DATA" | grep -i "portCfg:"

                echo "  Trying to change LLDP state to $OPERATION.."
                vsish -e set /net/portsets/$SWITCH/ports/$PORT/lldp/enable $OPERATION &> /dev/null

                LLDPSTATE=vsish -e get /net/portsets/$SWITCH/ports/$PORT/lldp/enable
                if [ "$LLDPSTATE" = "$OPERATION" ]; then
                        echo "  LLDP state successfully changed"
                else
                        echo "  ERROR: changing LLDP state failed"
                fi

        echo "------------------------------"
        echo ""
        fi

The above script is missing the `'s.
