Configuring a Reflector
This section describes how to configure a reflector, which loops traffic to an initiator. You can set reflector parameters based on each scenario.
Context
On the network shown in Figure 1 of "Configuring an RFC 2544 Generalflow Test Instance", the following two roles are involved in a generalflow test:
- Initiator: sends simulated service traffic to a reflector.
- Reflector: loops the service traffic to the initiator.
The reflector can loop all packets on a reflector interface or the packets matching filter criteria to the initiator. The filter criteria include a destination unicast MAC address or a port number.
Procedure
- Run system-view
The system view is displayed.
- Configure the reflector. The reflector settings vary according to usage scenarios.
- The reflector ID must be unique on a local node.
- The aging time can be set for a reflector.
Usage Scenario
Configuration Procedure
Configuration Note
Any scenario in which a reflector loops all packets
nqa reflector reflector-id interface interface-type interface-number [ exclusive ] [ exchange-port ]
On the network shown in Figure 1 of "Configuring an RFC 2544 Generalflow Test Instance", UNI-B is used as a reflector interface.
Layer 2
nqa reflector reflector-id interface interface-type interface-number [ mac mac-address ] [ pe-vid pe-vid ce-vid ce-vid | vlan vlan-id ] [ source-port source-port ] [ destination-port destination-port ] [ exchange-port ] [ agetime agetime | endtime { endtime | enddate endtime } ] [ share-mode ]
On the network shown in Figure 1 of "Configuring an RFC 2544 Generalflow Test Instance", the MAC address of the reflector's UNI-B or a MAC address that has never been used is used as the MAC address.
Layer 3
nqa reflector reflector-id interface interface-type interface-number [ ipv4 ip-address ] [ pe-vid pe-vid ce-vid ce-vid | vlan vlan-id ] [ source-port source-port ] [ destination-port destination-port ] [ exchange-port ] [ agetime agetime | endtime { endtime | enddate endtime } ] [ share-mode ]
NOTE:- In a Layer 3 scenario, static ARP must be configured first using the arp static ip-address mac-address command.
- In a Layer 3 scenario, the outbound interface must be specified when static ARP is configured on the reflector.
On the network shown in Figure 1 of "Configuring an RFC 2544 Generalflow Test Instance", an IP address on the same network segment as the reflector's UNI-B is used as the IP address.
IP gateway
nqa reflector reflector-id interface interface-type interface-number [ ipv4 ip-address | mac mac-address | simulate-ip ipv4 ip-address2 ] [ pe-vid pe-vid ce-vid ce-vid | vlan vlan-id ] [ source-port source-port ] [ destination-port destination-port ] [ exchange-port ] [ agetime agetime | endtime { endtime | enddate endtime } ] [ share-mode ]
NOTE:In the IP and IP gateway scenario, need to run the arp static ip-address mac-address command to configure a static ARP entry for the source IP address.
On the network shown in Figure 1 of "Configuring an RFC 2544 Generalflow Test Instance", an IP address on the same network segment as the reflector's UNI-B is used as the simulated IP address.
- Run commit
The configuration is committed.
