Cisco Aironet 1300 Wireless Bridge

We have a Cisco Aironet 1300 point to multipoint configuration for our main office to two small remote buildings. One of these bridges was mounted to a pole that was damaged in recent storms, and needs to be re-mounted. Everything is in working order. My question, how do i determine the signal strength? i am not seeing anything in the web interface for the bridge. All of this was originally installed by a contractor, i'm just trying to get this mounted and working again. Is there software available from Cisco? I know with some other manufacturers like SmartBridge, they offered a client app. I'm just not really familiar with this equipment. Thanks!

We have one of these set up. Combing through interface now.

When you say you are trying to determine signal strength, are you talking about determining what the strength of the receiving or sending signal?

Receiving, from the bridge that is in the process of being remounted.

I can connect to the receiving unit, and that is where i'm looking for some type of strength information so that i know it's properly in-line. I know there are LED indicators, but that seems to only tell you if you have an established link; which i do.

This is the only thing I can see that is testing the incoming transmission.

Do you have anything reading here?

That looks like your receiving transmission is extremely low.

I switched to my non-root bridge to see if they looked similar to yours, but they were significantly higher.

Here is average from the last 5 minutes:

5 Min Input Rate (bits/sec)       
5660000
5 Min Input Rate (packets/sec)       
1018

Judging by your bits/sec and your packets/sec rates it seems like your signal isn't very good.

Can you send some screen shots of the 802.11x settings page?

(Same section you were on above but click the "settings" tab at the top)

The bridge is still not mounted in the air, it's still at ground level...this is why i was looking for a way to determine signal strength for the device. I obviously want to mount it at the height that is going to provide maximum signal strength.

Your settings all look good. Do you have line of sight even though it isn't in the air?

"how do i determine the signal strength? i am not seeing anything in the web interface for the bridge."

You are not going to find it in the GUI as there is nothing there for it, you will need to access the CLI:

sh dot11 associations <MAC_address>

<MAC_address> is the mac of the device you want to capture to view the recieved signal strength.

"
Judging by your bits/sec and your packets/sec rates it seems like your signal isn't very good.
"

You can not use the bits/sec and packets/sec rates to determine whether or not a signal is good or bad.

Once you get access to the Cli: you will want to ensure the signal stregth is at least  -72 dBm for at least 54Mbps, 18 Mbps: you should be at -84 dBm, 24 Mbps: -81 dBm,  36 Mbps: -77 dBm, 48 Mbps: -73 dBm.

Sounds like you may need to realign the antennas

Thx rfc1180!

If you go to the Association page and check the radio listed there you should be able to see all radio stats including SNR and RSSI.  Also, as rfc said, you can issue the show dot11 associations command to see which radios are connected and their relevant stats in the CLI.

What ever happened with this? I am curious to hear the outcome.

We remounted the antenna, in the same approximate location it was in previously. Drastic improvement in signal strength. Thanks for the help.
