On EX4500, EX6200, and EX8200 switches, only the out-of-band management option is available. Port mirroring sends copies of all packets or policy-based sample packets to local or remote analyzers where you can monitor and analyze the data. For interfaces configured to support a VoIP VLAN and a data VLAN, the show vlans command displays both On EX2300 and EX3400 switches, you cannot create a new VLAN for management. Configure ports, routing instances, VLANs, or bridge domains for which the entering traffic is mirrored as part of a mirroring configuration. 1 for the QFX Series.

Under edit interfaces x/x/x unit 0 family ethernet-switching -> set vlan members vlan-name With method 1, if you have multiple vlans on same group of interfaces you could use copy vlan EX3300 devices. You can define the ingress VLAN ID or VLAN name Once in a while you are in need of analyzing traffic on a specific interface using Wireshark. VLANの作成 set vlans VLAN名 vlan-id VLAN番 Note: When you configure port mirroring on any interface under one VLAN, the mirrored packet can move to an external analyzer located on different VLANs. You can monitor Layer 3 VLAN statistics for a switch, router, Virtual Chassis, Layer 3 Fabric, and the Because it can be overwhelming to capture and analyze traffic on a production device when a lot of it is being exchanged between routers, filters are often used to narrow the capture data. The example below is for mirroring traffic Mirrored traffic is sent to a local interface, VLAN, or bridge domain for remote monitoring or analysis. On The device will insert a 4-byte VLAN tag (0x0001) in the egress mirrored packets. Switch is not throwing any Port mirroring / EX3300 configuration advice. Ideally I create an analyzer on my EX3300 top of rack switches, set the input to the ingress of ge-0/0/0 through 47, and send that to an analyzer VLAN (vlan-id 998) which gets trunked [edit vlans {vlan-name} forwarding-options] [edit vlans {vlan-name} interface {interface-name}] [edit vlans {vlan-name} interfaces {interface-name}] [edit vlans {vlan-name} pvlan] [edit vlans {name} switch Firewall filters provide a means of protecting your router (and switch) from excessive traffic transiting the router (and switch) to a network destination or destined for the Routing Engine.
