NETGEAR 8800 Chassis Switch CLI Manual • Ingress-Mirrors traffic received at the port. • Egress-Mirrors traffic sent from the port. • Ingress and egress-Mirrors all traffic forwarded by the port. (If you omit the optional parameters, all traffic is forwarded; the default for port-based mirroring is ingress and egress). • VLAN-All data to a particular VLAN, regardless of the physical port configuration, is copied to the monitor port. • Virtual port-All data specific to a VLAN on a specific port is copied to the monitor port. • Only 8 VLANs can be mirrored on a given physical port. • Only traffic ingressing a VLAN can be monitored; you cannot specify ingressing or egressing traffic when mirroring VLAN traffic. • When routing between VLANs, ingress mirrored traffic is presented to the monitor port as modified for routing. This is the default behavior and the behavior when you use the command, configure mirroring mode standard. When you use the command, configure mirroring mode enhanced, ingress traffic is mirrored as it is received (on the wire). • In standard mode (see configure mirroring mode command), even if you select ingress and egress traffic, the packet is mirrored only the first time it matches a mirror filter and is not mirrored on subsequent configured filters. In enhanced mode, packets which match both an ingress filter and an egress filter will result in two packets egressing the monitor port or ports. • You cannot include the monitor port for the NETGEAR 8800 series switch in a load-sharing group. • You can run mirroring and sFlow on the same device when you are running NETGEAR 8800. • With a monitor port on a NETGEAR 8800 original-series module, all traffic egressing the monitor port is tagged (regardless of what module the ingressing port is on). Even if some untagged ports send mirrored traffic to the monitor port, that traffic also egresses the monitor port tagged with the internal VLAN ID. • When you are using standard mode mirroring on an 8800, a packet that matches both an ingress mirroring filter and an egress mirroring filter may only be ingress mirrored. The behavior depends on the location of the ingress port, egress port and monitor port within the switch as well as the type of switch on which the packet ingresses. When using enhanced mode mirroring, two packets are mirrored when a packet encounters both an ingress and egress mirroring filter.r one-half of that module or on another module. Enhanced mirroring mode must be configured if you are going to configure a remote mirroring tag. Enhanced mirroring mode is configured using the following command: configure mirroring mode enhanced Note: This parameter is used for the remote port mirroring feature only. Chapter 5.
