1:N Mirroring Specifications

1:N Mirroring Specifications

  • Concept

    1:N mirroring binds one mirrored port to a number (N) of observing ports, as shown in Figure 9-9.

    Figure 9-9  1:N mirroring

    For 1:N port mirroring, a mirrored port can be bound to N observing ports in each direction (inbound and outbound).

    For 1:N traffic mirroring, a traffic mirroring behavior bound to a traffic classifier contains N observing ports that are configured in a batch. That is, to implement 1:N traffic mirroring, the traffic behavior must specify an observing port group.

    For 1:N VLAN mirroring or MAC address mirroring, the observing port group bound to the inbound direction of a VLAN contains N observing ports. That is, to implement 1:N VLAN mirroring or MAC address mirroring, you must bind an observing port group to the inbound direction of a VLAN.

    This section provides the specifications of 1:N port mirroring. The N values of other 1:N mirroring features are the same as those of 1:N port mirroring.

  • Specifications

    Huawei S series fixed switches of V200R003 and earlier versions do not support 1:N mirroring.

    A mirrored port can be bound to only one observing port or observing port group, which must be the same in both the inbound and outbound directions. One observing port group contains a maximum of 64 observing ports.

    S6720EI, S6720S-EI Y (Y ≤ 4) 4-Y (Y ≤ 4)

    In 1:N mirroring, if you bind a mirrored port to multiple observing ports in a batch in either the inbound or outbound direction, the mirrored port cannot be bound to other observing ports in the same direction.
