In V200R005 and later versions, there are two modes for configuring observing ports: single configuration and batch configuration. Both modes can be used simultaneously. If multiple observing ports are configured in a batch, these observing ports are bound to the same mirrored port. Therefore, batch configuration simplifies the configuration of 1:N mirroring. Figure 1 shows batch configuration of observing ports.
Calculating the Number of Available Observing Ports
The number of available observing ports depends on the total number of observing ports to which mirrored ports have been bound in the inbound and outbound directions. The number of observing ports to which a mirrored port is bound in the inbound direction is calculated separately to those bound in the outbound direction. When the same observing port is bound to the mirrored port in both the inbound and outbound directions, the numbers of available observing ports for inbound and outbound packets are both reduced by 1.
As shown in Figure 2, a maximum of eight observing ports can be configured on an S5720-EI. Inbound packets on all the mirrored ports can be copied and sent to a maximum of four observing ports, and outbound packets can be copied and sent to a maximum of four observing ports. If inbound and outbound packets on the mirrored ports are copied and sent to the same observing port, the numbers of available observing ports for inbound and outbound packets are both 3. Therefore, the total number of available observing ports is 6 (3 plus 3) but not 7 (8 minus 1).
The following tables list the observing port specifications for different devices.
