Configuration Roadmap
The configuration roadmap is as follows:
l Configure GigabitEthernet0/0/1 of Switch A as an observing port and specify the RSPAN
VLAN.
l Configure GigabitEthernet0/0/2 of Switch A as a mirrored port.
l Configure GigabitEthernet0/0/1 of Switch C as an observing port.
Data Preparation
To complete the configuration, you need the following data:
l Index of the observing port on Switch A: 1
l ID of the RSPAN VLAN on Switch A, Switch B, and Switch C: 2
l Index of the observing port on Switch C: 1
Configuration Procedure
1. Configure Switch A.
# Configure the RSPAN VLAN.
<SwitchA> system-view
[SwitchA] vlan 2
[SwitchA-vlan2] quit
# Configure GigabitEthernet0/0/1 of Switch A as an observing port and specify the RSPAN
VLAN.
[SwitchA] observe-port 1 interface gigabitethernet 0/0/1 vlan 2
# Add GigabitEthernet0/0/1 to the RSPAN VLAN as a trunk interface.
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type trunk
[SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 2
[SwitchA-GigabitEthernet0/0/1] quit
# Configure remote port mirroring for incoming traffic on GigabitEthernet0/0/2.
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port-mirroring to observe-port 1 inbound
[SwitchA-GigabitEthernet0/0/2] quit
