IP SLA transfer speed monitoring

Hi nchabra,

I believe this should be ftp. If you want to manually configure this, the link below woulld be very helpful:

http://etutorials.org/Networking/network+management/Part+II+Implementations+on+the+Cisco+Devices/Chapter+11.+IP+SLA/IP+SLA+CLI+Operations/

With this knowledge, you can configure this easily via IPSLAM as well. Hope this helps.

Let's say we wanted to do some type of ping which equates to 1 MB every hour from source 1.1.1.1 to destination 2.2.2.2? 

Here is what I have so far:

ip sla monitor 160
 type echo protocol ipIcmpEcho 172.27.254.1
 request-data-size 1500
 owner vnetdisc:Source-Dest-ping
 frequency 3600

ip sla monitor group schedule 2 160-185 schedule-period 300 start-time now life forever

Please let me know what is missing.

Thanks!

Ping is probably not a good choice to show data transfer rates. I would use FTP.

Defining HTTP FTP get operation CLI with absolute path. Get the file /home/user/test.cap

Defining HTTP FTP get operation CLI with relative path. Get the file /test.cap

The idea is to monitor network speed without actually transferring anything.  For example, an extended ping of the appropriate 'Repeat count' and 'Datagram Size' should emulate a 1MB transfer.  Is there something close to this with IP SLA?   

You could do that but I don't get the point of why you would. If you are going to measure 1 MB of pings why not just measure the transfer of a 1 MB file? ICMP never carries user data so you would only be measuring your network's ability to move pings.

We are trying to do an hourly speed check so we can see if there are times of congestion during the day.  Doesn't the 'ftp get' actually retrieve and store the file?  Can you do this from router to router?  Since this would be hourly and the file would be the same name, does the transfer take place and overwrite the existing file?'

Thanks

You can enable FTP server on a cisco router for router to router transfer time or use another FTP server. The operation will retiieve the file and overwrite it each time. Here is a good Cisco doc on this.
