I'm working with several cisco 1200 series APs, trying to get relevant client information off of them. It would be helpful to see RSSI and SNR for individual clients connected, but I am unable to find any commands that are related to this. I've checked around the cisco forums, and a lot of people were able to find this info using some perl scripts along with information from end user wireless cards, but that is not an option for me. I have remote access only to the APs. Other posts recommend using some kind of wireless controller to view this, but that is also not an option. Any suggestions are appreciated.
You state that a Wireless Controller is not an option, so I'm assuming these are Autonomous Access Points.
On Cisco Autonomous APs, you are looking for the
show dot11 associations command and it's associated sub commands.
It gives an output like so:
SPARKY#show dot11 associations 802.11 Client Stations on Dot11Radio0: SSID [sparky] : MAC Address IP address IPV6 address Device Name Parent State XXXX.da1d.1b05 172.20.1.102 :: unknown - self Assoc XXXX.2c90.c42f 172.20.1.103 :: unknown - self Assoc XXXX.59c0.4ac4 172.20.1.116 :: unknown - self Assoc
Once you have the MAC address of your client, you can run the
show dot11 associations <MAC ADDRESS> command where
<MAC ADDRESS> is the MAC address of the client you're interested in. It should give you all the information you're after. You can also run
show dot11 associations all-client and see this information for all associated clients. See the below sample:
SPARKY#show dot11 associations XXXX.da1d.1b05 Address : XXXX.da1d.1b05 Name : NONE IP Address : 172.20.1.102 IPv6 Address : :: Gateway Address : 0.0.0.0 Netmask Address : 0.0.0.0 Interface : Dot11Radio 0 Bridge-group : 1 reap_flags_1 : 0x0 ip_learn_type : 0x0 transient_static_ip : 0x0 Device : unknown Software Version : NONE CCX Version : NONE Client MFP : Off State : Assoc Parent : self SSID : sparky VLAN : 10 Hops to Infra : 1 Association Id : 3 Clients Associated: 0 Repeaters associated: 0 Tunnel Address : 0.0.0.0 Key Mgmt type : WPAv2 PSK Encryption : AES-CCMP Current Rate : m7-2 Capability : WMM ShortHdr ShortSlot Supported Rates : 1.0 2.0 5.5 11.0 6.0 9.0 12.0 18.0 24.0 36.0 48.0 54.0 m0-2 m1-2 m2-2 m3-2 m4-2 m5-2 m6-2 m7-2 Voice Rates : disabled Bandwidth : 20 MHz Signal Strength : -59 dBm Connected for : 209172 seconds Signal to Noise : 34 dB Activity Timeout : 25 seconds Power-save : Off Last Activity : 35 seconds ago Apsd DE AC(s) : NONE Packets Input : 8306 Packets Output : 4109 Bytes Input : 816594 Bytes Output : 565535 Duplicates Rcvd : 17 Data Retries : 803 Decrypt Failed : 0 RTS Retries : 0 MIC Failed : 0 MIC Missing : 0 Packets Redirected: 0 Redirect Filtered: 0 IP source guard failed : 0 PPPoE passthrough failed : 0 DAI failed : IP mismatch : 0 src MAC mismatch : 0 target MAC mismatch : 0 Existing IP failed : 0 New IP failed : 0 11w Status : Off Session timeout : 0 seconds Reauthenticate in : never
