Netflow Config

Answered Question

User Badges:

is there a way to have netflow send info on specific ip addresses (strictly in the config of a router). I will be trying to do this on a 2801.


Any feedback would be appreciated

hello Dwayne,

there is no support of an export filter in netflow at least in this kind of routers.


However, on the collector software you can build a filter from the GUI or you can process the ASCII format of the files from shell in order to grep what you want: it becomes a problem of filtering text files looking for some pattern that is the specific flow you look for.

In each file you can find 0,1 or multiple occurrences of the flow.


Hope to help

Giuseppe

Do you mean the router should send the flow statistics for only a particular set of conversation?


IF this is what you mean, then unfortunately this is not possible
