RPR configuration alert
OPTera Metro 3500 will generate an alarm and trap notifying users when the
maximum number of nodes on the RPR ring is exceeded.
The maximum number of nodes provisionable on a RPR ring are:
• 16 for RPR ring consisting only of 2xGigE.
• 12 for RPR rings consisting of a mix of 2xGigE with 4x100FX and/or
4x100BT cards.
An alarm and trap is sent following:
• the addition of the 17 node to the RPR ring which consists only of 2xGigE.
• the addition of the 13 node to RPR ring which consists of a mix of 2xGigE
with 4x100FX and/or 4x100BT cards.
All nodes which have their IP and trap receivable provisioned will send a trap
along with corresponding TL1 alarm. The trap and alarm clear when the
number of nodes on the RPR ring decreases:
• to 16 nodes or less for RPR ring which consists only of 2xGigE.
• to 12 or less RPR ring which consists of a mix of 2xGigE with 4x100FX
and/or 4x100BT cards.
Auto save notification
New traps were introduced in Release 12.0 informing user that unsaved
changes have been made to the provisioning of an OPE card.
Traps
• provDataSaveRequiredTrap
This trap will be sent after any provisioning change. It will provide
notification to the Network Management tools that some data has been
modified and has not been saved to NVRam.
• provDataLostTrap
This trap will be sent after there was a provisioning change, which was not
saved and either a cold or warm restart occurred. In this case the unsaved
provisioning data will be lost. It will provide notification to the Network
management tools that some data was lost.
A new variable “Provisioning Data” was added to the “System Device Info”
field to reflect the status of the provisioning data. This allows the user to query
the provisioning data status at anytime and perform the correct actions
depending on the data status. The data statuses are:
— default: provisioning data is the default data
— saved: the provisioning data was saved
— save required: unsaved changes to provisioning date have been made
— data lost: provisioning data is lost
