Remote Traffic Mirroring Configuration Example - 3Com S7906E Configuration Manual

[Sysname] traffic classfier 1
[Sysname-classifier-1] if-match acl 2000
[Sysname-classifier-1] quit
# Create traffic behavior 1 and configure the action of mirroring traffic to GigabitEthernet 2/0/2 for the
traffic behavior.
[Sysname] traffic behavior 1
[Sysname-behavior-1] mirror-to interface GigabitEthernet 2/0/2
[Sysname-behavior-1] quit
# Create QoS policy 1 and associate traffic behavior 1 with class 1 in the QoS policy.
[Sysname] qos policy 1
[Sysname-policy-1] classifier 1 behavior 1
[Sysname-policy-1] quit
# Apply QoS policy 1 to the inbound direction of GigabitEthernet 2/0/1.
[Sysname] interface GigabitEthernet 2/0/1
[Sysname-GigabitEthernet2/0/1] qos apply policy 1 inbound
After the configurations, you can monitor all packets from Host A on the data monitoring device.

Remote Traffic Mirroring Configuration Example

Network requirements
As shown in Figure
GigabitEthernet 2/0/2 of Switch A is connected to the 10.1.1.1/24 network segment.
GigabitEthernet 2/0/2 of Switch C is connected to the data monitoring device.
Switch B connects Switch A and Switch C, as shown in
Configure remote traffic mirroring to mirror the packets which are from the 10.1.1.1/24 network segment
and received on GigabitEthernet 2/0/2 of Switch A to the data monitoring device.

Configuration procedure
Configuration on Switch A
# Configure basic IPv4 ACL 2000 to match packets from the 10.1.1.1/24 network segment.
<SwitchA> system-view
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 10.1.1.1 255.255.255.0
