What is IP SLA ICMP echo?
What is IP SLA ICMP echo?
The ICMP Echo operation measures end-to-end response time between a Cisco router and any devices using IP. In the figure below ping is used by the ICMP Echo operation to measure the response time between the source IP SLAs device and the destination IP device.
What is IP SLA monitoring?
An IP service level agreement, or IP SLA, is a network measurement technology that uses active traffic monitoring data to analyze the performance of a network in real time. It collects time-based performance data that actively helps monitor and troubleshoot a network.
What is IP SLA timeout?
Timeout sets the amount of time (in milliseconds) for which the Cisco IOS IP SLAs operation waits for a response from its request packet. Threshold sets the rising threshold that generates a reaction event and stores history information for the Cisco IOS IP SLAs operation.
How do you create an IP SLA?
To implement IP SLAs network performance measurement, you need to perform these tasks:
- Enable the IP SLAs responder, if required.
- Configure the required IP SLAs operation type.
- Configure any options available for the specified operation type.
- Configure threshold conditions, if required.
How do I know if my IP SLA is working?
To display the status of IP Service Level Agreements (SLAs) auto discovery and the configuration of auto IP SLAs endpoint lists configured to use auto discovery, use the show ip sla auto discovery command in user EXEC or privileged EXEC mode.
Why is IP SLA used?
IP SLA is an active method of monitoring and reliably reporting on network performance. By “active,” I refer to the fact that IP SLA will generate and actively monitor traffic continuously across the network. An IP SLA Router is capable of generating traffic and reporting on it in real time.
How do I monitor IP SLA?
VoIP UDP Jitter – Measure VoIP call path metrics. ICMP Echo – Measure round-trip delay. UDP Echo – Measure response times between IP SLA nodes using IP. ICMP Path Echo – Discover a network path using traceroute and measure the response time between a Cisco router and devices using IP.
What is use of IP SLA in networking?
IP SLA is used to track network performance like latency, ping response, and jitter, it also helps us to provide service quality.
What is a good SLA?
The SLA should include not only a description of the services to be provided and their expected service levels, but also metrics by which the services are measured, the duties and responsibilities of each party, the remedies or penalties for breach, and a protocol for adding and removing metrics.
What is IP SLA command?
To configure an IP Service Level Agreements (SLAs) Internet Control Message Protocol (ICMP) echo operation, use the icmp-echo command in IP SLA configuration mode. icmp-echo {destination-ip-address | destination-hostname} [source-ip {ip-address | hostname} | source-interface interface-name]
How to change the IP SLAs ICMP Echo operation?
To change the operation type of an existing IP SLAs operation, you must first delete the IP SLAs operation (using the no ip sla global configuration command) and then reconfigure the operation with the new operation type. IP SLAs ICMP echo operations support both IPv4 and IPv6 addresses.
How is Ping used in the ICMP Echo operation?
In the figure below ping is used by the ICMP Echo operation to measure the response time between the source IP SLAs device and the destination IP device. Many customers use IP SLAs ICMP-based operations, in-house ping testing, or ping-based dedicated probes for response time measurements. Figure 1. ICMP Echo Operation
How is response time measured in ICMP echo?
The ICMP Echo operation measures end-to-end response time between a Cisco router and any devices using IP. Response time is computed by measuring the time taken between sending an ICMP Echo request message to the destination and receiving an ICMP Echo reply.
How is response time measured in IP SLAs?
Response time is computed by measuring the time taken between sending an ICMP Echo request message to the destination and receiving an ICMP Echo reply. In the figure below ping is used by the ICMP Echo operation to measure the response time between the source IP SLAs device and the destination IP device.
