EX2300 switches provide connectivity for low-density environments.

Benefits of the EX2300 Switch

Economical—EX2300 switches offer an economical, entry-level,standalone solution for access-layer deployments in branch and remoteoffices, as well as enterprise campus networks. 1 Gbps and 2.5 Gbpsaccess port options provide high speed options, especially when connectingto 802.11ac Wave 2 access points.

High flexibility and class leading features—EX2300 switchesprovide the highest levels of flexibility and features in its classto support data, voice, and video environments, delivering a reliableplatform for unifying enterprise communications.

Support for Juniper Networks Junos Fusion Enterprise—EX2300switches can act as a satellite device to support a Juniper NetworksJunos Fusion Enterprise deployment, which can combine severalwiring closets into one logical management platform. In smaller networks,you can connect up to four EX2300 switches in a Virtual Chassis configuration,allowing them to be managed as a single switch.

  Note

  This concept uses Junos OS for EX Series switches withsupport for the Enhanced Layer 2 Software (ELS) configuration style.

  Mirroring might be needed for traffic analysis on a switch becausea switch, unlike a hub, does not broadcast packets to every port onthe destination device. The switch sends packets only to the portto which the destination device is connected.

  Juniper Networks EX2300, EX3400, and EX4300 Ethernet Switchessupport the following mirroring methods: port mirroring and analyzers.You can use port mirroring or analyzers to facilitate analyzing trafficon these switches at the packet level. You might use analyzers aspart of monitoring switch traffic for such purposes as enforcing policiesconcerning network usage and file sharing and for identifying sourcesof problems on your network by locating abnormal or heavy bandwidthusage by particular stations or applications.

  Mirrored packets can be copied either to a local interface forlocal monitoring or to a VLAN for remote monitoring. The followingpackets can be copied:

  • Packets entering a VLAN—Youcan mirror the packets entering a VLAN to either a local analyzerport or to an analyzer VLAN. You can configure multiple VLANs (upto 256 VLANs),including a VLAN range and PVLANs, as ingress input to an analyzer.

  • port-mirror or name to the inputor output logical interfaces (including aggregated Ethernet logicalinterfaces), to traffic forwarded or flooded to a VLAN, or trafficforwarded or flooded to a VPLS routing instance. EX2300, EX3400, andEX4300 switches support port mirroring of VPLS (family vpls) traffic and VPN traffic with then statement in either of the following ways:

    • Implicitly reference the port-mirroring properties ineffect on the port.

    • Explicitly reference a particular named instance of portmirroring.

    You can configure port mirroring at the family statement is set to inet6.

    Analyzer Overview

    You can configure an analyzer to define both the input trafficand output traffic in the same analyzer configuration. The input trafficto be analyzed can be traffic that enters or exits an interface, ortraffic that enters a VLAN. The analyzer configuration enables youto send this traffic to an output interface, instance, or VLAN. Youcan configure an analyzer at the TermDescription

    Analyzer

    In a mirroring configuration (analyzer) on an EX2300, EX3400,or EX4300 switch, the analyzer includes:

    • The name of the analyzer

    • Source (input) ports or VLAN

    • A destination for mirrored packets (either a monitor portor a monitor VLAN)

    Analyzer output interface

    (Also known as monitor port)

    Interface to which mirrored traffic is sent and to which a protocolanalyzer application is connected.

    Note: Interfaces used as output for an analyzer must be configuredunder the

    Analyzer VLAN

    (Also known as monitor VLAN)

    VLAN to which mirrored traffic is sent. The mirrored trafficcan be used by a protocol analyzer application. The member interfacesin the monitor VLAN are spread across the switches in your network.

    Port mirroring

    A port-mirroring configuration that does not specify an inputsource; it specifies only an output destination. A firewall filterconfiguration must be defined for the input source. A firewall filterconfiguration must be defined to mirror packets that match the matchconditions defined in the firewall filter term. The action item instance-name inthe firewall filter configuration is used to send packets to the analyzerand these packets form the input source.

    Global port mirror

    A port mirroring configuration that does not have an instancename. The firewall filter action

    Input interface

    (Also known as mirrored ports or monitored interfaces)

    An interface on the switch that is being mirrored. Traffic thatis either entering or exiting this interface is mirrored.

    LAG-based analyzer

    An analyzer that has a link aggregation group (LAG) specifiedas the input (ingress) interface in the analyzer configuration.

    Local mirroring

    An analyzer configuration in which packets are mirrored to alocal analyzer port.

    Monitoring station

    A computer running a protocol analyzer application.

    Native analyzer session

    An analyzer session that has both output definitions in its analyzer configuration.

    Policy-based mirroring

    (Also known as port mirroring)

    Mirroring of packets that match the match items in the definedfirewall filter term. The action item instance-name is used in the firewall filter tosend the packets to the monitor port.

    Port-based analyzer

    An analyzer session whose configuration defines interfaces forboth input and output.

    Protocol analyzer application

    An application used to examine packets transmitted across anetwork segment. Also commonly called network analyzer, packet sniffer,or probe.

    Remote port mirroring

    Functions the same way as local port mirroring, except thatthe mirrored traffic is not copied to a local analyzer port but isflooded to an analyzer VLAN that you create specifically for the purposeof receiving mirrored traffic.

    VLAN-based analyzer

    An analyzer session whose configuration uses VLANs for bothinput and output or for either input or output.

    Configuration Guidelines for Port Mirroring and Analyzers onEX2300, EX3400, and EX4300 Switches

    When you configure port mirroring or analyzers on EX2300, EX3400,and EX4300 switches, we recommend that you follow certain guidelinesto ensure that you obtain optimum benefit from mirroring. Additionally,we recommend that you disable mirroring when you are not using itand that you select specific interfaces for which packets must bemirrored (that is, select specific interfaces as input to the analyzer)in preference to using the

      • A maximum of four analyzer sessions.

      • A combination of port-mirroring and analyzer sessions,and the total of this combination must be four.

    Packets with physical layer errors are not sent to the localor remote analyzer.

    Applicable

    Packets with these errors are filtered out and thus are notsent to the analyzer.

    Port mirroring for line-rate traffic is done on a best-effortbasis.

    Mirroring of packets egressing a VLAN.

    Port-Mirroring Limitation

    • True egress mirroring is defined as mirroring the exact numberof copies and the exact packet modifications that went out the egressswitched port. Because the processor on EX2300 and EX3400 switchesimplements egress mirroring in the ingress pipeline, those switchesdo not provide accurate egress packet modifications, so egress mirroredtraffic can carry incorrect VLAN tags that differ from the tags inthe original traffic.
