NAME

check_tc4400

SYNOPSIS

check_tc4400 <OPTIONS>

OPTIONS

• H,hostname HOSTNAME

  Hostname or ip address of your tc4400 modem.

• u,username username

  Username to authenticate with to the modem's webinterface.

• p,password password

  Password to authenticate with to the modem's webinterface.

• r,read filename

  Read data from file (usually for debugging purposes).

• i,ignore {docsis30|docsis31}

  Do not check thresholds for {docsis30|docsis31}. Collect perfdata though. Useful when your line performance is really bad but your modem works nonetheless, or you're connected both with docsis 3.0 and 3.1 but the modem only uses either of them.

• s,startle

  Startle the modem by sending an unauthorized dummy request prior to the "real" request for data. Use this workaround if your modem randomly times out with check_tc4400.

DESCRIPTION

- Connectivity State is not "OK"
- Boot State is not "OK"
- Configuration File is not "OK"
- Security is not "Enabled"
- downstream channel is not "Locked"
- downstream channel signal/noise ratio is below a predefined value
- downstream channel transmission level is odd
- upstream channel transmission level is odd

see 20180617_Pegelwerte.pdf for thresholds.
