Line State Colours

Line colours are based on the last cause code reported by RADIUS which depends on whether the line is on-line or off line and why.

The cause codes are defined by the standard (RFC2866) and do not always fit all circumstances.

Logged in	Line is logged in, no error
User Request	PPP restart or termination from far end, or L2TP session close from far end. This means either that your router ended the PPP session cleanly (e.g.for a reboot), or that the wholesale provider terminated the session as part of maintenance work. Appears as UserRequest in e-mails.
Lost Carrier	LCP echo timeout. The session has remained up, but LCP packets aren't getting through - this usually means that the line is down. Appears as LostCarrier in e-mails.
Lost Service	L2TP session close with specific message indicating loss of sync. Appears as LostService in e-mails.
Idle Timeout	Used to indicate a lost session, e.g. NAS crash.
Session Timeout	Session timeout reached (normally after one hour on a blocked login)
Admin Reset	Manual or remote session or tunnel termination
Admin Reboot	LNS reboot or other RADIUS accounting issue
Port Error	L2TP relay failure, or L2TP tunnel level close
NAS Error	Any unknown internal error in LNS including no negotiation slots (too busy)
NAS Request	Session steering (directed to different LNS)
NAS Reboot	Not used
Port Unneeded	Try another response on RADIUS (steering)
Port Pre-empted	Same login twice. As login is based on circuit ID this is not normally seen.
Port Suspended	Line dropped because of an attack
Service Unavailable	RADIUS timeout
Callback	Not used
User Error	Any sort of PPP negotiation failure, or an authentication failure and also some L2TP negotiation errors
Host Request	Not used
Blocked	Line is logged in but blocked due to bad password or blocked login - check the password in your router, then contact support for help.
Invalid	Line not valid (not installed, or is ceased)
