Create a service chain object
A
service
chain
represents a particular service function path through the SFC
configuration. A service chain automates the task that network
administrators traditionally do to connect a set of L4-7 devices to process network
traffic.The object needs a name and some associated information, namely a path ID
and a start index. You must also specify whether you want the service chain to be
enabled or disabled. This procedure creates a new service chain object.Except for changing the BIG-IP Policy Enforcement
Manager (PEM) classifier policies associated with a chain, you cannot modify a chain
object after you have created it. In general, if you need to modify a chain, you
must delete the chain and re-create it.
- From the SFC controller menu on the left side of the screen, selectService Function Chains.
- In the upper left corner, clickCreate.The Create New Service Chain screen opens.
- Type a unique name for the chain.In our sample configuration, this ischain1.
- Type a path ID, such as880.This ID is an identifier for the service chain and is used by service nodes for forwarding.
- In theStart Indexfield, type an index number, such as255.This index number is a location identifier for a packet within the service path.
- 4. From theClassifierlist, select an SFF, and choose the list of classification rules to be applied.In our sample configuration, this SFF issff1.
- 5. From the right side of the screen, drag all SFs and drop them into the chain, in the correct order.
- ClickCreate.
After completing this task, the SFC configuration contains a service chain representing a defined path.
