VT-SLM (VT Path Signal Label Mismatch) The controller card is detecting a signal label mismatch in the VT path. A received signal label is mismatched if it does not equal the locally provisioned value or the value "equipped nonspecific". VT-UEQ (VT Path Unequipped) The controller card detects that the VT path is unequipped. The VT path is not provisioned. Byte V5 of the STS path overhead is set to zero. System Traps Trap If enabled, the unit issues a trap when... Protection Switching Protection Switch all data has been routed from the primary card to the stand-by card. Card Removed a controller card has been removed. Card Failure a controller card has failed. This is a critical alarm only when the back-up card is not installed or is not working properly. Communication Fail communication between controller cards A and B has failed. Max Switches the MAX SWITCH THRESHOLD is reached (see Max. Switch Threshold on page 3-6). 61200659L1-1 MX2800 STS-1 User Manual Chapter 3. Configuration Trap If enabled, the unit issues a trap when... System Timing Clock Status there is a change in clock status. The clock status can be any of the following values: NORMAL – clock synchronization is operating normally. RECOVERING – clock synchronization is in the process of recovering from a fault. LOSS OF SOURCE – the reference clock source has become invalid OUT OF RANGE – the clock synchronization circuit is unable to track the reference source. OUT OF LOCK – the clock synchronization circuit is unable to lock to the reference source. Clock Source there is a Clock Source Change event Change indicating that the unit has switched clock sources. The values for the clock source change alarm are: Loop PRI Ext SEC Ext Free-run Holdover PRI EXT Clock a failure condition is encountered on either the Status PRImary or SECondary clock sources (if configured). The possible values for this alarm are: DISABLED NORMAL AVAILABLE LOS/AIS FAIL UNAVAILABLE 3-32 MX2800 STS-1 User Manual 61200659L1-1 Chapter 3. Configuration Trap If enabled, the unit issues a trap when... SEC EXT Clock Status a failure condition is encountered on either the PRImary or SECondary clock sources (if configured). The possible values for this alarm are: DISABLED NORMAL AVAILABLE LOS/AIS FAIL UNAVAILABLE Activity Loss there is a critical hardware failure in which a Status clock source has become inactive. The MX2800 STS-1 continually checks for activity on all of its internal clock sources as part of its status monitoring. If any clock source fails, the corresponding clock source will be displayed in the status menu and a TRAP/Syslog condition will be generated. If all clocks are operating normally, no indication is shown on the menu. Again, this condition is only encountered during a hard card failure and the customer should contact ADTRAN technical support if this occurs. Power Supply Alarm Traps Trap If enabled, the unit issues a trap when... Card Removed the power supply card has been removed Malfunction the power supply card is no longer working and the unit has switched to the backup power supply or battery backup Card Failure the power supply card has failed Power Low the power supply’s output level is abnormally low 61200659L1-1 MX2800 STS-1 User Manual Chapter 3. Configuration Trap If enabled, the unit issues a trap when... Bat. Backup Active Battery charger has lost its AC source and is now running off the battery backup Battery Low the battery backup has reached a critical energy point at which it may be unable to supply the unit with sufficient power to maintain operation Temperature High the power supply card is getting too hot Temperature Crit the power supply card temperature is so high that it may suffer damage MIB II Standard Alarm Traps Trap If enabled, the unit issues a trap when... Cold Start the unit is first powered up Link Up the STS-1 is up with no alarms Link Down the STS-1 is in alarm Auth. Failure an attempt has been made by an unauthorized user to access the unit Read Community Name Enter the authentication strings used for SNMP management. Match the MX2800 STS-1 to the SNMP manager for read privileges. Write Community Name Enter the authentication strings used for SNMP management. Match the MX2800 STS-1 to the SNMP manager for write privileges. Trap Community Name Enter the identification string used for trap management. This string accompanies all traps transmitted by the MX2800 STS-1. 3-34 MX2800 STS-1 User Manual 61200659L1-1 Chapter 3. Configuration System Security Password Set the password required at login (up to 32 characters). The default password is adtran (all lower case). Terminal Timeout Set the amount of time the terminal or Telnet session remains inactive before automatically closing the session, requiring the user to log in again. The options include DISABLED, 1 MIN., 5 MIN., 15 MIN., 60 MIN., or 1 DAY. IP Security Enable or disable the IP SECURITY option. If ENABLED, the unit accepts management commands and Telnet sessions from ...
