Configuring IP SLAs FTP Operations
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 at the end of this module.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required.
Restrictions for IP SLAs FTP Operations
The IP SLAs FTP operation only supports FTP GET (download) requests.
Information About IP SLAs FTP Operations
FTP Operation
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 network nodes.
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.
Note |
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
Note |
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
- Configuring an FTP Operation with Optional Parameters on the Source Device
Configuring a Basic FTP Operation on the Source Device
1. enable
2. configure terminal
3. ip sla operation-number
4. ftp get url [source-ip {ip-address | hostname}] [mode {passive | active}
5. frequency seconds
6. end
DETAILED STEPS
Configuring an FTP Operation with Optional Parameters on the Source Device
1. enable
2. configure terminal
3. ip sla operation-number
4. ftp get url [source-ip {ip-address | hostname}] [mode {passive | active}
5. history buckets-kept size
6. history distributions-of-statistics-kept size
7. history enhanced [interval seconds] [buckets number-of-buckets]
8. history filter {none | all | overThreshold | failures}
9. frequency seconds
10. history hours-of-statistics-kept hours
11. history lives-kept lives
12. owner owner-id
13. history statistics-distribution-interval milliseconds
14. tag text
15. threshold milliseconds
16. timeout milliseconds
17. end
DETAILED STEPS
Scheduling IP SLAs Operations
- All IP Service Level Agreements (SLAs) operations to be scheduled must be already configured.
- The frequency of all operations scheduled in a multioperation group must be the same.
- The list of one or more operation ID numbers to be added to a multioperation group must be limited to a maximum of 125 characters in length, including commas (,).
- ip sla schedule operation-number [life {forever | seconds}] [start-time {[hh:mm:ss] [month day | day month] | pending | now | after hh:mm:ss}] [ageout seconds] [recurring]
- ip sla group schedule group-operation-number operation-id-numbers {schedule-period schedule-period-range | schedule-together} [ageout seconds] [frequency group-operation-frequency] [life {forever | seconds}] [start-time {hh:mm [:ss] [month day | day month] | pending | now | after hh:mm [:ss]}]
1. enable
2. configure terminal
3. Enter one of the following commands:
4. end
5. show ip sla group schedule
6. show ip sla configuration
DETAILED STEPS
Troubleshooting Tips
- 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.
- Use the debug ip sla trace and debug ip sla error 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 active mode.
Device B Configuration
ip sla 10 ftp get ftp://user1:abc@test.cisco.com/test.cap mode active frequency 20 tos 128 timeout 40000 tag FLL-FTP ip sla schedule 10 start-time 01:30:00 recurring
