M:N Mirroring Specifications

M:N Mirroring Specifications

M:N mirroring binds a number (M) of mirrored ports to a number (N) of observing ports.

An M:N mirroring rule is equivalent to multiple 1:N mirroring rules, as shown in Figure 8-11. The number of mirrored packets is not limited, and the number of observing ports is the same as that in 1:N mirroring.

Figure 8-11  M:N mirroring

For the devices listed in the following table, if the total incoming traffic (or outgoing) volume on all mirrored ports is X in a unit time period (typically 1s) and the number of observing ports is N, the production of X and N cannot be greater than the specified value (Z). If the production of X and N is greater than Z, some mirrored packets may be lost. The following table describes the Z values for different devices.
