Example for Configuring an Ethernet Service Activation Test in a Layer 3 Scenario
This section provides an example for configuring an Ethernet service activation test in a Layer 3 scenario to check whether network performance meets SLAs.
Networking Requirements
The network shown in Figure 4-14 requires a check of the Ethernet frame transmission between Device B and Device C to determine whether the performance parameters meet SLAs.
Configuration Roadmap
- Configure Device C as the reflector and set filter criteria based on flows.
- Configure Device B as the initiator and execute configuration tests and performance tests.
Data Preparation
To complete the configuration, you need the following data:
- Configurations of reflector Device C: Configure the reflector to reflect traffic based on flows.
Configurations of initiator Device B:
Configure service flow and service flow characteristics.
- Destination MAC address: 2-2-2, that is, the MAC address of GE0/1/1 on Device D connected to UNI B
- Source MAC address: 1-1-1, that is, the MAC address of GE0/1/1 on Device A connected to UNI A
Destination IP address: IP address of the downstream device or the IP address of the network segment where UNI B resides. An example of the IP address of the downstream device is 10.1.3.2.
Source IP address: IP address of the downstream device or the IP address of the network segment where UNI A resides. An example of the IP address of the downstream device is 10.1.1.1.
Configure the bandwidth template: CIR as 500000 kbit/s and EIR as 20000 kbit/s
Configure service acceptance criteria: with the FLR set to 1000/100000, FTD set to 1 microsecond, and FDV set to 10000000 microseconds.
NOTE: The link between the two user networks must
be reachable. Otherwise, static ARP entries must be configured.
Procedure
- Configure the Layer 3 link reachability for the initiator and reflector.
- Configure the reflector.
