Allied Telesis AT-WR4500 manual Sniffer Sniff, Submenu level /interface wireless sniffer

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

tls-mode(no-certificates dont-verify-certificate verify-certificate; default: no-certificates) - TLS certificate mode

no-certificates- certificates are negotiated dynamically using anonymous Diffie-Hellman MODP 2048 bit algorithm

dont-verify-certificate- require a certificate, but do not chack, if it has been signed by the available CA certificate

verify-certificate- require a certificate and verify that it has been signed by the available CA certificate unicast-ciphers(multiple choice: tkip aes-ccm) - a set of ciphers used to encrypt frames sent to individual wireless station (unicast transfers) in the order of preference

tkip - Temporal Key Integrity Protocol - encryption protocol, compatible with lagacy WEP equipment, but enhanced to correct some of WEP flaws

aes-ccm- more secure WPA encryption protocol, based on the reliable AES (Advanced Encryption Standard). Networks free of WEP legacy should use only this

wpa-pre-shared-key(text; default: "") - string, which is used as the WPA Pre Shared Key. It must be the same on AP and station to communicate

wpa2-pre-shared-key(text; default: "") - string, which is used as the WPA2 Pre Shared Key. It must be the same on AP and station to communicate

￿

The keys used for encryption are in hexadecimal form. If you use 40bit-wep, the key has to be 10 characters long, if you use 104bit-wep, the key has to be 26 characters long.

Wireless encryption cannot work together with wireless compression.

4.3.17Sniffer

Submenu level: /interface wireless sniffer

Description

With wireless sniffer you can sniff packets from wireless networks.

Property Description

channel-time(time; default: 200ms) - how long to sniff each channel, if multiple-channels is set to yes

file-limit(integer; default: 10) - limits file-name's file size (measured in kilobytes)

file-name(text; default: "") - name of the file where to save packets in PCAP format. If file-name is not defined, packets are not saved into a file

memory-limit(integer; default: 1000) - how much memory to use (in kilobytes) for sniffed packets

multiple-channels(yes no; default: no) - whether to sniff multiple channels or a single channel no - wireless sniffer sniffs only one channel in frequency that is configured in /interface wireless yes - sniff in all channels that are listed in the scan-list in /interface wireless

only-headers(yes no; default: no) - sniff only wireless packet heders

receive-errors(yes no; default: no) - whether to receive packets with CRC errors

streaming-enabled(yes no; default: no) - whether to send packets to server in TZSP format

streaming-max-rate(integer; default: 0) - how many packets per second the router will accept 0 - no packet per second limitation

streaming-server(IP address; default: 0.0.0.0) - streaming server's IP address

4.3.18Sniffer Sniff

Submenu level: /interface wireless sniffer sniff

Description

Wireless Sniffer Sniffs packets

Property Description

file-over-limit-packets(read-only: integer) - how many packets are dropped because of exceeding file- limit

file-saved-packets(read-only: integer) - number of packets saved to file
