Bug ID 740049: Programming SFC path using CLASSIFICATION / URLCAT filter does not work

Last Modified: Sep 14, 2023

Affected Product(s):
BIG-IP PEM(all modules)

Known Affected Versions:
14.1.0,,,,,, 14.1.2,,,,,,,,, 14.1.3,, 14.1.4,,,,,,, 14.1.5,,,,,

Opened: Aug 11, 2018

Severity: 3-Major


If PEM POLICY has a rule that uses CLASSIFICATION / URLCAT filter to choose the SFC path, the NSH programming does not always work.


In such a situation, the NSH programming does not take effect. Flow does not reach all the service functions.


-- SCF uses FastL4 and PEM. -- SCF uses standard virtual server and classification happens after the initial exchange of a few packets. The NSH programming happens after the flow is established to the server.


Use only flow filter for subscriber-aware programming of SFC.
