Allied Telesis AT-WR4500 manual Traffic-FlowTarget, Traffic-Flow Example

AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers	259
RouterOS v3 Configuration and User Guide

Property Description

active-flow-timeout(time; default: 30m) - maximum life-time of a flow

cache-entries(1k 2k 4k 8k 16k 32k 64k 128k 256k 512k; default: 1k) - number of flows which can reside in the router's memory simultaneously

enabled (yes no) - whether to enable traffic-flow service or not inactive-flow-timeout(time; default: 15s) - how long to keep the flow active, if it is idle interfaces (name) - names of those interfaces which will be used to gather statistics for traffic-flow. To specify more than one interface, separate them with a comma (",")

12.3.4Traffic-FlowTarget

Submenu level: /ip traffic-flow target

Description

With Traffic-Flow targets we specify those hosts which will gather the Traffic-Flow information from router.

Property Description

address (IP address:port) - IP address and port (UDP) of the host which receives Traffic-Flow statistic packets from the router

v9-template-refresh(integer; default: 20) - number of packets after which the template is sent to the receiving host (only for NetFlow version 9)

v9-template-timeout- after how long to send the template, if it has not been sent version (1 5 9) - which version format of NetFlow to use

12.3.5Application Examples

Traffic-Flow Example

This example shows how to configure Traffic-Flow on a router

Enable Traffic-Flow on the router:

[admin@AT-WR4562] ip traffic-flow> set enabled=yes

[admin@AT-WR4562] ip traffic-flow> print enabled: yes

interfaces: all cache-entries: 1k active-flow-timeout: 30m inactive-flow-timeout: 15s

[admin@AT-WR4562] ip traffic-flow>

Specify IP address and port of the host, which will receive Traffic-Flow packets:

[admin@AT-WR4562] ip traffic-flow target> add address=192.168.0.2:2055 \ \... version=9

[admin@AT-WR4562] ip traffic-flow target> print Flags: X - disabled

#	ADDRESS	VERSION
0	192.168.0.2:2055	9

[admin@AT-WR4562] ip traffic-flow target>

Now the router starts to send packets with Traffic-Flow information.
