//The following combines the two set filters

//defined above into one FilterExpression.

//It works unmodified as a discovery filter.

//To work as a map filter, network and segment filtering

//must be added (see below).

VitalNodes "All Gateways and Servers" { GatewaysSet ServersSet }

//One can turn the filters defined above into viable map or

//topology filters by simply adding " NetsNSegs". (Doing so

//does not invalidate the filters as discovery

//filters. It just adds a superfluous test.)

//Using the filters defined above that include only a specific

//network, we can also exclude the specific network like this

//Note the use of the more specific form to exclude only the segments

//in the engineering lan. This could have been specified directly

//as a negation in the filter part, but this form works well if you

//have several networks to manipulate in this manner. EverythingButEngr "Everything but the engineering LAN"

//Of course the above filter expressions, when used as

//map filters, pass all networks and segments. You

//may wish to see only a particular network. The following map

//filters accomplish this. Note that though segments

//and nodes from other networks will pass the filters, IP Map

//will ignore them because their parent networks will not pass.

//NOTE: These filters will not work as Discovery

//filters because all network and segments automatically pass

//Discovery and Topology filters.

//all Ungermann-Bass are kept in memory and up to date.
