2.2.6. Capture and monitoring interfaces: aggregation

2.2.6.1. Aggregation principle ("cluster")

For more information, refer to Capture and monitoring interfaces between TAP and GCap.

---

2.2.6.2. CLI commands

Displaying the current aggregation is achieved with the show interfaces command.
Configuring the aggregation is done with the set interfaces command.

---

2.2.6.3. Use case procedures

For implementation, refer to the Procedure for managing capture interface aggregation.

---

2.2.6.4. Aggregation configuration

Aggregation creation is done via the GCap Command Prompt (CLI).

---

2.2.6.5. Impact on other functionalities

The aggregation functionality of the capture interfaces on the GCap leads to a degradation of some related functions:

• Maximum Transmission Unit (MTU): the maximum size of a packet that can be transmitted at one time without fragmentation.
  The MTU uses the largest value of the interfaces making up the aggregation.

• Static rules for filtering flows captured by monitoring interface: XDP (eXpress Data Path) filter function.
  XDP Filter: XDP filtering is not applied by default to the aggregation created but rather to the interfaces that comprise it.
