How Many Observing Ports Do CE Series Switches Support?

How Many Observing Ports Do CE Series Switches Support?

On CloudEngine 12800 and 12800E series switches
  • A CE12800 or CE12800E (except the CE12800E that has the FD-X series cards installed) can have a maximum of eight observing ports configured and use these observing ports simultaneously.

  • A CE12800E that has the FD-X series cards installed can have a maximum of four observing ports configured and use these observing ports simultaneously.

  • Since V100R003C00, a CE12800 has supported a maximum of 128 observing port groups, but can use at most 8 observing port groups at a time. Each observing port group can have at most 64 observing ports. An observing port group is a group of observing ports. Packets copied to an observing port group will be copied to all the observing ports in the group.

  • The CE12800E does not support observing port groups.

The CloudEngine 16800 series switches can have a maximum of eight observing ports configured and use these observing ports simultaneously, and do not support observing port groups.

On CloudEngine 8800, 7800, 6800, and 5800 series switches
  • In V100R006C00 and earlier versions, the switch can have a maximum of eight observing ports configured but can use at most two observing ports at a time. Each observing port can be used to copy both incoming and outgoing traffic.

  • In V200R001C00 and later versions, a switch can have a maximum of eight observing ports configured. A CE6880EI, CE6870EI, CE6875EI, or CE5880EI switch can use at most eight observing ports at a time, while other switch models can use at most four observing ports at a time. On a CE6870EI, CE6875EI, CE6880EI or CE5880EI switch, each observing port can be used to copy both incoming and outgoing traffic. On a switch except CE6870EI, CE6875EI, CE6880EI and CE5880EI, the maximum numbers of available observing ports for incoming and outgoing traffic are calculated separated. When the same observing port is specified for both incoming and outgoing traffic, the remaining number of observing ports for incoming and outgoing traffic is 2 not 3.

  • A CE6870EI or CE6875EI switch also supports observing port groups and can have at most 128 observing port groups configured, but can use at most 8 observing port groups at a time. Each observing port group contains at most 64 member ports. An observing port group is a group of observing ports. Packets copied to an observing port group will be copied to all its member ports.
