This module describes how to configure an IP Service Level Agreements (SLAs) File Transfer Protocol (FTP) operation to measure
the response time between a Cisco device and an FTP server to retrieve a file. The IP SLAs FTP operation supports an FTP GET
request only. This module also demonstrates how the results of the FTP operation can be displayed and analyzed to determine
the capacity of your network. The FTP operation can be used also for troubleshooting FTP server performance.
Finding Feature Information
Your software release may not support all the features documented in this module. For the latest caveats and feature information,
see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module,
and to see a list of the releases in which each feature is supported, see the feature information table.

Restrictions for IP SLAs FTP Operations
The IP SLAs FTP operation only supports FTP GET (download) requests.
Information About IP SLAs FTP Operations
The FTP operation measures the round-trip time (RTT) between a Cisco device and an FTP server to retrieve a file. FTP is
an application protocol, part of the Transmission Control Protocol (TCP)/IP protocol stack, used for transferring files between
In the figure below Device B is configured as the source IP SLAs device and an FTP operation is configured with the FTP server
as the destination device.
Connection response time is computed by measuring the time taken to download a file to Device B from the remote FTP server
using FTP over TCP. This operation does not use the IP SLAs Responder.
To test the response time to connect to an FTP port (Port 21), use the IP SLAs TCP Connect operation.
Both active and passive FTP transfer modes are supported. The passive mode is enabled by default. Only the FTP GET (download)
operation type is supported. The URL specified for the FTP GET operation must be in one of the following formats:
If the username and password are not specified, the defaults are anonymous and test, respectively.
FTP carries a significant amount of data traffic and can affect the performance of your network. The results of an IP SLAs
FTP operation to retrieve a large file can be used to determine the capacity of the network but retrieve large files with
caution because the FTP operation will consume more bandwidth. The FTP operation also measures your FTP server performance
levels by determining the RTT taken to retrieve a file.
How to Configure IP SLAs FTP Operations
Configuring an FTP Operation on a Source Device
There is no need to configure an IP SLAs responder on the destination device.
Perform one of the following tasks:
Configuring a Basic FTP Operation on the Source Device
Device(config)# ip sla schedule 10 life forever start-time now
Device(config)# ip sla group schedule 10 schedule-period frequency
Device(config)# ip sla group schedule 1 3,4,6-9 life forever start-time now
Device(config)# ip sla schedule 1 3,4,6-9 schedule-period 50 frequency range 80-100
Configures the scheduling parameters for an individual IP SLAs operation.
an IP SLAs operation group number and the range of operation numbers for a
configuration mode and returns to privileged EXEC mode.
Device# show ip sla group schedule
Displays IP SLAs group schedule details.
Device# show ip sla configuration
Displays IP SLAs configuration details.
If the IP Service Level Agreements (SLAs) operation is not running and not generating statistics, add the
verify-data command to the configuration (while configuring in IP SLA configuration mode) to enable data verification. When data verification
is enabled, each operation response is checked for corruption. Use the
verify-data command with caution during normal operations because it generates unnecessary overhead.
debugipslaerror commands to help troubleshoot issues with an IP SLAs operation.
What to Do Next
To add proactive threshold conditions and reactive triggering for generating traps (or for starting another operation) to
an IP Service Level Agreements (SLAs) operation, see the “Configuring Proactive Threshold Monitoring” section.
Configuration Examples for IP SLAs FTP Operations
Example: Configuring an FTP Operation
The following example shows how to configure an FTP operation from Device B to the FTP server as shown in the "FTP Operation"
figure in the "Information About IP SLAs FTP Operation" section. The operation is scheduled to start every day at 1:30 a.m.
In this example, the file named test.cap is to be retrieved from the host, cisco.com, with a password of abc using FTP in
Device B Configuration
ip sla 10
ftp get ftp://user1:email@example.com/test.cap mode active
ip sla schedule 10 start-time 01:30:00 recurring
