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 8-7.

    Figure 8-7  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.

    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

    Table 8-3 lists the 1:N mirroring specifications in the inbound and outbound directions for different series of cards. The 1:N mirroring specifications include the numbers of observing ports to which inbound and outbound packets on a mirrored port can be copied.


    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.

    Table 8-3  1:N mirroring specifications in the inbound and outbound directions of different series of cards
    Card Number of Observing Ports to Which a Mirrored Port Can Be Bound in the Inbound Direction Number of Observing Ports to Which a Mirrored Port Can Be Bound in the Outbound Direction
    ET1D2X12SSA0 2 2
    SC series cards Y (Y ≤ 4) 4-Y (Y ≤ 4)
    E series cards, except ET1D2X48SEC0 and ET1D2C02FEE0 2 2
    ET1D2X48SEC0 and ET1D2C02FEE0 Y (Y ≤ 4) 4-Y (Y ≤ 4)
    X series cards

    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.
