The "Target" tag allows you to "add" multiple interface stats together
into one graph, by using the "+" sign to seperate them.
For instance:
Target[131.252.1.5.53]: 29:xxx at 131.252.1.5 + 3:xxx at 131.252.1.5 + 5:xxx at 131.252.1.5
Directory[131.252.1.5.53]:coresw
MaxBytes[131.252.1.5.53]: 5000000
Title[131.252.1.5.53]: coresw (): <font color="#6B238E"> <B> Aggregate
Traffic: VLAN 1 </B> </font>
PageTop[131.252.1.5.53]: <H1>Traffic Analysis for <font color="#6B238E">
<B> Aggregate Traffic: VLAN 1 </B> </font>
</H1>
<TABLE>
<TR><TD>System:</TD><TD>coresw in NOC</TD></TR>
<TR><TD>Maintainer:</TD><TD>CNS Net, 725-9565</TD></TR>
<TR><TD>Interface:</TD><TD><font color="#6B238E"> <B> Aggregate
Traffic: VLAN 1 </B> </font> (53)</TD></TR>
<TR><TD>IP:</TD><TD> ()</TD></TR>
<TR><TD>Max Speed:</TD>
<TD>12.5 MBytes/s (propVirtual)</TD></TR>
</TABLE>
-------------------------------
This gives us a picture of aggrate traffic on VLAN1, for instance.
Sorry I wasn't more clear...
