DiffServ

This will select only traffic bearing one of the selected differentiated service code
points. Since DiffServ and ToS use the same field in the IP header you should not use

both filters at the same time. You can assign a name to a code point using the

DiffServ

Names

settings page.

Traffic class

This filter selects traffic with the given traffic class. In order for traffic classes to be

identified the NetFlow device must support the functionality and its traffic class
mapping must be configured in

Device Settings

.

Source AS

You can select traffic bearing one of a set of source AS numbers. Whether this is the

origin or peer AS depends on the configuration of the router (see

Appendix 1

). You can

enter an AS number manually or select from the set of private-use ASes configured in

the

AS Names

settings page; note that you cannot select public ASes by name to avoid

the filter page being excessively large.

Dest AS

This restricts the source data to traffic bearing the given destination origin or peer

ASes.

Src/dest AS

This filter considers traffic to or from the given origin or peer ASes.

Source subnet

This will select traffic with the given source subnet. You can enter the network address
and mask length manually or select from the subnets configured in the

Subnet Names

settings page. Note that the subnet mask used by the router to route the traffic is
ignored when applying this filter.

Dest subnet

This filter selects traffic with the given destination subnets. Note that a destination

subnet filter of 224.0.0.0/4 will select multicast traffic.

Src/dest subnet

This filter selects traffic to or from the given subnets.

Source mask

This will select traffic routed using the given source network mask.

Dest mask

This filter selects traffic with the given destination network mask.

Src/dest mask

This filter selects traffic with the given source or destination network mask.

Next hop

This will filter traffic according to the next hop used by the router in routing the traffic.
