Body
The ifconfig command outputs its <a href="http://docs.sun.com/app/docs/doc/816-5166/6mbb1kq2q?l=en&a=view#INTERFACE%20FLAGS" rel="nofollow noreferrer">flags</a> in both textual and numeric format. While I can find a reference <a href="http://books.google.com/books?id=t7pHu7sIUkQC&pg=PA139&lpg=PA139&dq=ifconfig+numeric+flags&source=bl&ots=5tG7fK7qzf&sig=A5Z4Gem5mmDeeFsiue4LIeFpVgk&hl=en&ei=7POTSuPxDo2KswPZ69TPDw&sa=X&oi=book_result&ct=result&resnum=1#v=onepage&q=ifconfig%20numeric%20flags&f=false" rel="nofollow noreferrer">here or there</a> to the numeric flags, I cannot find any indication on how to interpret (mask) the number. <pre><code>qfe2: flags=1100843<UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4> mtu 1500 index 4 usesrc vni0 inet 1.2.3.4 netmask ffffff00 broadcast 1.2.3.255 ether 0:3:ba:17:4b:e1 vni0: flags=20011100c1<UP,RUNNING,NOARP,NOXMIT,ROUTER,IPv4,VIRTUAL> mtu 0 index 5 srcof qfe2 inet 3.4.5.6 netmask ffffffff </code></pre> In the above output, note the following: <pre><code>flags=1100843<UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4> </code></pre> The numeric value "<code>1100843</code>" maps to the flags "<code>UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4</code>". Is there a reference somewhere that I'm simply not seeing that describes how to mask each flag (<code>UP,BROADCAST,</code>etc.) out of the encoded "<code>flags=NNNNNNNN</code>" value? EDIT: Clarification of exactly which flag I'm interested in masking.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
