To keep the NFM-T database in sync with the nodes in the network
What is downloaded from the node during full node synchronization?
All items from the node, including NE parameters, ports, alarms, internal links, etc.
What is NOT a purpose of node synchronization?
To test the reachability of a node
What is the benefit of node synchronization?
Allows network administrators to ensure that their network is up to date and running efficiently
What is NOT downloaded from the node during full node synchronization?
Data not related to the node
Why is node synchronization important?
To keep track of any changes made to the nodes
What is NOT a result of node synchronization?
The time of the node is aligned with the time of the NFM-T platform
What is the outcome of full node synchronization?
All items from the node are downloaded to the NFM-T database
Study Notes
OAMP LAN Interface
- An RJ-45 interface (common Ethernet port) used to connect one or more client ports (e.g., 1Gb/s or legacy 100Mbit/s client flows)
- Used to connect the OAMP node to the LAN, allowing it to be managed and monitored remotely
- Must be configured with an IP address for node reachability and management
Logs and Alarms
- Logs: a record of events that have occurred within a system, including system activity, configuration changes, and error messages
- Logs report both active (real-time) and historical events that have occurred within a system
- Alarms and conditions: used to notify operators of real-time status of the node, such as when a threshold is breached or when a specific event occurs
Node Synchronization
- Allows several entities/items defined at EPT level to be retrieved into the NFM-T database (upload from design)
- Full synchronization retrieves all items from the node, including NE parameters, ports, alarms, internal links, etc.
- Ensures that the NFM-T database is up to date and the network is running efficiently
GMRE Activation Status
- Can be checked via ping request from NFM-T
Metro Area Network (MAN)
- A telecommunications network that spans a metropolitan area and connects multiple local area networks (LANs) or business networks together
- Typically covers an area larger than a LAN but smaller than a WAN
Interface Details
- Command
show interface 11starla 1/17/L1 detailis used to check for interface details, displaying information about the specified interface, including its status, configuration, and statistics
