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 (",")
12.3.4 Traffic-Flow Target
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
12.3.5 Application 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.
