Enhanced Network Visibility: Monitor Nokia SAP/SDP Logical Interfaces with Kentik

Introducing expanded insights into Nokia devices with SNMP Ingest for SAP VPLS Interfaces.

This update significantly enhances Kentik's visibility into Nokia networks by adding krpoxy support for SNMP collection of utilization metrics from logical Service Access Point (SAP) and Service Distribution Point (SDP) VPLS interfaces on Nokia Layer 2 devices. Previously, accessing this critical data required navigating vendor-specific MIBs outside of the standard IF-MIB. Now, Kentik simplifies this process.

How it Works:

Kentik's kproxy server now automatically performs an snmpwalk of the necessary vendor-specific MIBs to gather interface index information and dynamically create corresponding interfaces within Kentik. This eliminates the need to build custom configurations and provides immediate access to performance data.

How to Access:

1. Navigate to Settings > Networking Devices in the Kentik portal.
2. Add your Nokia Layer 2 devices.
3. Once the devices are active, the new SAP/SDP interface dimensions will be available in the Data Explorer's dimensions selector. These new dimensions will only be visible for accounts with active Nokia Layer 2 devices.

Benefits:

• Improved Network Visibility: Gain deeper insights into the performance and utilization of Nokia VPLS services over time.
• Simplified Monitoring: Native dimensions eliminate the need to custom configurations
• Enhanced Troubleshooting and Analysis: Leverage granular data to quickly identify and resolve performance issues affecting Nokia-based VPLS services.

Understanding Nokia SAPs and SDPs:

To provide context, here's a brief overview of the key concepts involved:

• Service Access Point (SAP): A SAP represents the customer interface point for a service on a Nokia 7450 ESS or 7750 SR OS device, a local entity uniquely identified by Physical port, Encapsulation type, and Encapsulation identifier (ID)
• Service Distribution Point (SDP): An SDP acts as a logical connection, directing traffic between Nokia 7450 ESS/7750 SR devices via a unidirectional service tunnel. The SDP terminates on the remote router, which then forwards packets to the appropriate egress SAPs. A distributed service comprises at least one SAP on a local node, one SAP on a remote node, and an SDP binding the service to the service tunnel.
