F5 LTM Profile simple Example
When you check the configuration of a virtual server in F5 LTM, you see many profiles that can be assigned to the virtual server.
Now we request access to the web server through virtual IP address and then use the “pktcap-uw” command with the “–switchport” option to capture comings and goings from the first web server. We save the output of the capture in a file called “withoutprofile.pcap”.
Therefore, we can download the capture file and check the contents of the packets using wireshark software.
if we check DSCP field captured traffic, you can see that they are all “0x00”, which is the default value.
In the next step, we assign the new profile to the virtual server.
The profile will be assigned to the section, „Protocol Profile (Server)“.
Therefore, in this section, we could change the behavior of a specific traffic passing through the virtual server using the LTM profile.
LTM profile in tmsh
now let’s check to see what is the tmsh version of ltm profile.
With the command „list ltm profile“, we can check the list of supported LTM profiles.
In the output we can also see the new tcp profile created in this section.
And with the command „list ltm virtual“, we can check how profile is assigned to to the virnetual server.
