Traffic Mirroring; Remote Traffic Mirroring - H3C S7500 Series Operation Manual

Operation Manual – Mirroring
H3C S7500 Series Ethernet Switches
Caution:
To ensure the normal packet mirroring, you are not recommended to perform any of the
following operations on the remote-probe VLAN:
Configuring a source port to the remote-probe VLAN that is used by the local
mirroring group;
Configuring a Layer 3 interface for the remote-probe VLAN;
Running other protocol packets, or bearing other service packets;
Using remote-probe VLAN as a special type of VLAN, such as voice VLAN or
protocol VLAN;
Configuring other VLAN-related functions.

1.1.3 Traffic Mirroring

Traffic mirroring maps traffic flows that match specific ACL rules to the specified local
port for packet analysis and monitoring. Before configuring traffic mirroring, you need to
define ACL rules required for flow identification.

1.1.4 Remote Traffic Mirroring

Remote traffic mirroring copies traffic flows that match specific ACLs to the reflector
port of the specified mirroring group. Then, after corresponding configurations of
remote port mirroring, the matching traffic flows are finally copied to the specified ports
of other switches. Similar to configuring local traffic mirroring, you need to define ACL
rules required for flow identification first. Otherwise, you need to complete all
configurations of remote port mirroring (except the configuration of source port for
mirroring).
