Introduction : About LiveNX : IP SLA Module
IP SLA Module
The LiveNX IP SLA technology module makes Cisco IOS IP service level agreement (SLA) operations easily accessible for generating synthetic network traffic to monitor latency, loss, jitter, and mean opinion score (MOS) for VoIP. For more details, refer to IP SLA.
Features
Latency, loss, jitter, and MOS performance measurements
System wide IPSLA hub and spoke and mesh configurations
Test types: DHCP, DNS, FTP, HTTP, ICMP Echo, Jitter, Path Echo, Path Jitter, UDP Echo
Traffic type configuration
Protocol type: more than 10 protocol types
DHCP: destination, source, circuit ID, remote ID, subnet mask
Test frequency setting
Jitter test parameters—VoIP codec simulation (G.711 ulaw, G.711 alaw, G.729a)
Mode: active or passive
Packet priority: normal or high
Precision: in microseconds or milliseconds
IP SLA topology view (real time)
Multiple colors for visualization
Loss indicators
Normal and above-threshold indicators
Lists of running tests (indicating source, type, status)
Quick and full test options
Set up responder at destination
Start/Stop traffic tests
Edit, save, or delete test configurations
Export results to CSV file
Historical reporting (live update averages over timeline)
Variable sampling rates: from 10 seconds to 5 minutes
Latency: milliseconds over time, microseconds for jitter
Loss: number of dropped packets
VoIP MOS range: 1-5
