Juniper add interface to vlan. 1R7. 0; then set internet address on irb. Juniper Routing Instances On a Juniper switch or router, we can create additional virtual routing tables, called routing-instances. The purpose of this article is to describe the VLAN configuration process for setting up VLANs and trunks on EX Series (ELS and legacy) Switches and QFX devices, as well as how to verify their successful creation. Within a VLAN, traffic is bridged, while across VLANs, traffic is routed. Hi, I'm new to juniper. In this post, we will look at configuring VLANs, trunk ports, and IRB (or VLAN) interfaces on Junos devices. You must configure a logical interface with the VLAN ID that is same as the native VLAN ID confiured on the interface, to receive the untagged packets on the interface. When an Ethernet LAN is divided into VLANs, each VLAN is identified by a unique 802. after years away from JunOS, working with Foundry (now Brocade) routers, I find myself with a new Juniper MX10. Configure the media MTU for a physical interface and the MTU for a protocol to optimize traffic over your network. Jul 25, 2016 · With method 1, if you have multiple vlans on same group of interfaces you could use copy vlan xxx to vlan yyy. These are similar to a VRF on a Cisco Router. All I want to do is create a simple VLAN such that two ports share one routing inter Hi Ninjai, A vlan on a juniper switch is its own boadcast domain. An IRB is a special type of Layer 3 virtual interface named vlan. A VLAN with multiple interfaces could then use an IRB interface (or “vlan” interface in older Junos) as its layer 3 service interface. We have 1 Cisco 2960 and 1 Juniper EX2200. I ended up explicitly adding the 'default' VLAN to the vlans section, set it's vlan id to 1 (apparently you can't set l3-interface irb. You can configure a routed VLAN interface (RVI) for a private VLAN (PVLAN) on an EX Series Virtual Chassis. In this post I’ll be covering the process of creating VLAN’s on a Juniper switch and assigning interfaces to them. 0. Configure the interface range "test" to be a part of a vlan (vlan10, in this case): user@juniper# set interfaces interface-range test unit 0 family ethernet-switching vlan members vlan10 Add member interfaces (actual physical interface) to the interface range: user@juniper# set interfaces interface-range test member-range ge-0/0/0 to ge-0/0/10 This guide will show you the basics to managing VLANs on a Juniper EX switch: Create the VLAN Enter the CLI: cli Enter the Configuration mode: configure Enter the new VLAN name: set vlans vlan100 Set the VLAN ID for the new VLAN name: set vlans vlan100 vlan-id 100 Save the changes: commit Apply the VLAN to a network port Apply the VLAN to a physical network port: set interfaces ge-0/0/6 unit 0 Note: Another method to achieve the same requirement is to delete the existing VLAN membership and set up a new VLAN membership, which can be done as follows: View the current VLAN membership of a port or an interface. It looks like you are adding the interface to the incorrect vlan I assume that irb. Re-write all the VLANs in the command “switchport trunk allowed vlan vlan-id, vlan-id,vlan-id “ including the new VLAN and paste it on the interface. To configure the logical interface, include the vlan-id statement (matching the native-vlan-id statement on the physical interface) at the [edit interfaces interface-name unit logical-unit Add SR-IOV Interfaces SR-IOV interfaces must be added as PCI devices on VMware. traffic is flowing between the switches. The factory default configuration includes a predefined VLAN named vlan-trust and a VLAN interface named vlan. Because traffic between VLANs must be routed, a common Layer 3 interface is required. interface gi-1/0/28 and interface ge-0/1/3 are setup as trunk with native vlan-id DATA. Creating the VLANs’s is very simple. Solution To create inter VLAN routing by using routed VLAN interfaces (RVI), perform the following procedure: Create a layer 2 VLAN: root# set vlans <vlan-name> vlan-id <vlan-id> (1. Associate a Layer 3 interface with the VLAN. 4094)> Create a arrow_backward arrow_forward Note: This topic applies only to the J-Web Application package. Nothing will be overwritten so no worries: set interface vlan unit 100 family inet addres 10. Like normal Layer 3 interfaces, the vlan interface needs a logical unit number with an IP address. To configure switch settings at the site level, select Site > Switch Configuration from the left menu of the Juniper Mist portal. 1/24 and as a Layer 3 interface. 411 would be under VLAN411_MGMT and not default. This is the first in a series of blog posts covering some of the basics of Junos. For both Gigabit Ethernet and aggregated Ethernet interfaces and 802. For Fast Ethernet and Gigabit Ethernet interfaces, aggregated Ethernet interfaces configured for VPLS, and pseudowire subscriber interfaces, enable the reception and transmission of 802. You can configure both VLAN-tagged and untagged aggregated Ethernet with or without LACP enabled. x and adding family inet with address, then linking that interface to the vlan. When you add an interface to the bundle, the physical interface is deleted as a regular interface and then added back as a member. And you also need to create the interface itself under interfaces Now, delete your current interface ge-0/0/4, remove it from the trust security zone and re-create it as a switching interface in the new VLAN. To configure organization-wide settings, select Organization > Switch Templates from the left menu of the Juniper Mist portal. . These are shown below : Routed Ports – Layer 3 (inet) Bridge – Layer 2 (only used for transparent mode) Ethernet-switching – Layer 2 (switchport) Within this article we will look at how to configure a trunk and access port as switchports (aka ethernet-switching). wildcard set interfaces ge-0/0/[0-9,13,20-23] unit 0 family ethernet-switching interface-mode access vlan members <vlan> This is basically what the Cisco interface range command does: takes your line of config and pastes it onto all of the interfaces individually. 0 that is assigned to an IP address of 192. A maximum transmission unit (MTU) is the largest data unit that can be forwarded without fragmentation. I wanted I just set this switch up for testing , had the the same error, try my config, and just change How to configure aggregated Ethernet interfaces on Junos. 1Q VLAN tag ID to a logical interface. Assigning an IP block enables the clients to communicate through the VLAN. The ezsetup does not work (command line Hello, I am new to this forum and i bought my first Juniper Switch (EX2300-C). Better way is to add VLAN with below command which will just add the new VLAN into trunk port and keep all the old one’s. 1Q Tagging, assign an 802. Just some feedback. To add an SR-IOV interface as a PCI Device, you must first select an available Virtual Function (VF) on the device. Using this approach reduces complexity and avoids the costs associated with purchasing, installing, managing, powering, and cooling another device. 168. LACP is one method of bundling several physical interfaces to form one logical interface. VLAN need to be associated with a physical interface to route the traffic. Virtual LANs (VLANs) allow network architects to segment LANs into different broadcast domains based on logical groupings. 9. Jan 27, 2026 · This guide provides a clear, step-by-step approach to adding VLANs to interfaces on Juniper devices, emphasizing best practices to ensure proper network segmentation and functionality. In this example we’ll create 2 VLAN’s, SALES and IT with VLAN ID’s 100 and 200 Note: If the IP address isn't configured on the Avaya IP phone, the phone exchanges LLDP-MED information to get the VLAN ID for the voice VLAN. Cisco and Juniper both have CLI option to configure multiple interfaces within single line EX Series switches use a routed VLAN interface (RVI) to perform these routing functions, using it to route data to other Layer 3 interfaces. On the SRX Branch Series each interface can be configured as either layer 2 or layer 3. x/yy Thanks, 4. If the interface on which you are configuring OSPF supports broadcast mode (such as a LAN), or if the interface supports point-to-point mode (such as a PPP interface or a point-to-point logical interface on Frame Relay), you specify the interface by including the IP address or the interface name for OSPFv2, or only the interface name for OSPFv3. Whenever there is a need to split a interface into multiple sub interfaces then the unit # is referenced. 1Q tags one at a time for a trunk interface, you can configure a VLAN range to create a series of tagged VLANs. 802. Description Configure the VLAN identifier to associate untagged packets received on a trunk interface. In addition, you must assign this logical interface a VLAN ID from 512 through 1023; if the VLAN ID is 511 or lower, it is subject to the normal destination filter lookups in addition to You have no vlans configured under set vlans vlan-name That worked! Thank you very much. x/yy set interface vlan unit 100 family inet addres 192. NOTE: This assumes that your AP is expecting VLAN 4 to be tagged towards it - you may lose access to the management interface unless you also add a native-vlan-id to this port, which will require another using flexible-vlan tagging terminate the vlans on physical "wan"-interface create l3 interface and vlan-interfaces add vlan interfaces to different vlan-zones (create NAT rules and policies) untagg og tagg the vlans on "family ethernet-switching" on other "lan" is this correct approach? 2. Then create your template and apply it to one or more sites or site groups. During this time, the details of the physical interface are lost. The IRB interfaces are layer 3 interfaces for VLANs, similar to Cisco VLAN or SVI interfaces. The topic below describes the configuration of these tagged VLANs, VLAN IDs, and supported Ethernet interface types. For example, if you have two interfaces, and an untagged packet passes into the first interface with a user-configured native VLAN ID, it passes out of the second interface with the same VLAN ID as the tagged packet. 1X authentication for Port-Based Network Access Control. This process allows multiple VLANs to share the same physical link, effectively segmenting the network while maintaining a high degree of flexibility and efficiency. To access the VLAN Configuration page: By using the input-vlan-map and the output-vlan-map statements at the [edit interfaces interface-name unit logic-unit-number] or [edit logical-systems logical-system-name interfaces interface-name unit logic-unit-number] hierarchy level to configure VLAN mapping. 1. The vlan-id will need to be changed but the interfaces will be copied. In this blog, we discuss the interface range commands in Juniper. 1Q tag. Symptoms How to create a routed VLAN interface (RVI) for inter VLAN routing. Cisco and Juniper both have CLI option to configure multiple interfaces within single line Archived User Posted 02-22-2012 03:31 Reply Reply Privately Hey, Exactly the same way you would do it on any other Junos device - just add additional IP. x on VLANs without a vlan-id), and set it's associated layer-3 interface as irb. Sorry if this a dumb question. 6. The IRB interfaces are layer 3 interfaces for VLANs and are the same as Cisco VLAN or SVI interfaces. 1X authentication is supported on interfaces that are members of private VLANs (PVLANs). In this tutorial, we will cover configuring VLANs, trunk ports, and IRB (or VLAN) interfaces on Junos devices. On the switch, you can create "router" to route between the vlans using a Layer 3 interface named vlan. Adding a VLAN to an interface on Juniper devices involves a systematic configuration process. Follow these steps to ensure proper setup and network segmentation: Jan 29, 2026 · The purpose of this article is to describe the VLAN configuration process for setting up VLANs and trunks on EX Series (ELS and legacy) Switches and QFX devices, as well as how to verify their successful creation. Description This article provides information on how to create a routed VLAN interface (RVI) for inter VLAN routing. 4R1. Configure Layer 3 interfaces on trunk ports to allow the interface to transfer traffic between VLANs. Instead of configuring VLANs and 802. Key thing - multiple interfaces are bridged together at layer 2. The commands here are based on the Enhanced Layer 2 Software (ELS) style of CLI which is […] For Junos OS Evolved, when a new interface is added as a member to the aggregated Ethernet bundle, a link flap event is generated. how to add vlan to trunk port and how to verify if its done correctly? VLANs and Trunks VLANs using VPTv3 Trunks Intervlan routing using L3-SW, ROAS, cisco ASA, fortigate In this blog, we discuss the interface range commands in Juniper. You can use the VLAN Configuration page to add a new VLAN or to edit or delete an existing VLAN on an EX Series switch. The model of switch I am using is an EX2200-C, running Junos 11. x. The below topics discuss the overview Aggregated Ethernet (AE) interfaces on security devices, configuration details of AE interfaces, physical interfaces, AE interface link speed, VLAN tagging for aggregated Ethernet interfaces, and deleting an Aggregated Ethernet interface in security devices. For aggregated Ethernet interfaces, you can configure the Link Aggregation Control Protocol (LACP). The logical interface on which untagged packets are to be received must be configured with the same native VLAN ID as that configured on the physical interface. Instead of a router connected to a promiscuous port routing Layer 3 traffic between isolated and community members, you can alternatively use an RVI. To configure VLAN with L3 routing, follow the next steps: By using the input-vlan-map and the output-vlan-map statements at the [edit interfaces interface-name unit logic-unit-number] or [edit logical-systems logical-system-name interfaces interface-name unit logic-unit-number] hierarchy level to configure VLAN mapping. Juniper Tips [EX/QFX/MX]: How to utilize wildcard, interface-range, and apply-groups to mass manage port configs Configure IEEE 802. 1Q VLAN-tagged frames on the interface. Is it possible to have 15 and 30 tagged on an interface like ge-0/0/12 while 10 is untagged? If so, how? If I set the interface port-mode to “trunk,” it seems all the member VLANs are automatically tagged. Adding multiple VLANs to a trunk on a Juniper interface is a common task in network configuration. In a dynamic profile, you can configure VLAN subscriber interfaces over the following statically created logical interface types: The range for native-vlan-id is 0 to 4094. As you might guess, I’m brand new to Juniper… I’m working with an EX3200-48t running Junos 15. For Juniper Networks EX or QFX Series switches, the following article details steps to verify whether an IRB (called VLAN interface on legacy platforms) interface is up, and the steps to troubleshoot when it is down. This topic describes the topology for configuring subscriber interfaces over static VLAN interfaces. 3 and later, an OSPF point A logical interface cannot have vlan-ccc or vlan-vpls encapsulation unless the physical device also has vlan-ccc or vlan-vpls encapsulation, respectively. Each routing instance groups routing tables (remember different tables are used for different families), interfaces, and protocol configuration into a single place. A unit number identifies the particular subinterface of the main interface We can’t use the “sh vlan” command, but we can either use the “sh vlan-switch brief” command or the “vl” macro in exec mode: Despite the router saying to create/delete VLANs in config mode instead of vlan database, both of those macros will take you out to the vlan database, and then return you to global config mode automatically. Specify multiple VLAN identifiers to create a VLAN for each VLAN identifier. RE: srx multiple vlans on wan interface If I edit an AE Interface to add an additional VLAN to it when I do the commit will that Interface drop or go down/offline? I've searched all over Google and Youtube and I can't find an answer to that specific question. It groups all devices into a specific (vlan) group as per the vlan membership of the interface on the switch through which the devices are connected. In Junos OS Release 9. You must configure the voip statement on the interface to designate the interface as a VoIP interface and allow the switch to forward the VLAN name and VLAN ID for the voice VLAN to the IP telephone. VLANs can be assigned to interfaces in many ways and following is a simple method to assign a physical interface xe-0/0/07 to the vlan-10 juniper-1# set vlans vlan-10 interface xe-0/0/07 5. how to add vlan to trunk port and how to verify if its done correctly? The below topics discuss the overview Aggregated Ethernet (AE) interfaces on security devices, configuration details of AE interfaces, physical interfaces, AE interface link speed, VLAN tagging for aggregated Ethernet interfaces, and deleting an Aggregated Ethernet interface in security devices. 4oqw, nindkm, i34q, cfx3m, supr, rwjwqq, r3xsrs, jaau, 1vbb, 0z1htv,
