    CPE510v2 monitoring Signal status

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hello...is it possible to get the values of Signal strength, noise and SNR without weblogin to monitor these values via external Tools like Nagios?

    I don't think so.

    SNMP allows to collect information about a network device which has a public MIB. But CPE supports SNMPv1/2 and has a private MIB, parameter values of CPE can not obtained via external tools.

    Since Pharos Control (an administrative controller for CPEs) can manage to read those values without logging into the web UI, any other utility should be able to do this also. You just have to find out how Pharos Control achieves this (probably using SNMP).

    As a last resort, you could use ssh to grab those values using the CLI. Since this device is running Linux, be somewhat creative:

    Code:
    $ ssh admin@192.168.1.254 iwconfig ath0
    admin@192.168.1.254's password: 
    ath0      IEEE 802.11na  ESSID:"XXXXXXXXXXX"  Nickname:"RFS-1"
              Mode:Master  Frequency:5.64 GHz  Access Point: 98:DE:D0:12:34:56   
              Bit Rate:300 Mb/s   Tx-Power=17 dBm   
              RTS thr=2346 B   Fragment thr:off
              Encryption key:none   Security mode:open
              Power Management:off
              Link Quality=94/94  Signal level=-36 dBm  Noise level=-95 dBm
              Rx invalid nwid:22856  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    There you have it. Calculate the SNR from signal and noise levels. You could use an expect(1) script to automate the ssh dialog asking for the password.
