- Juniper add interface to vlan. Associate a Layer 3 interface with the VLAN. 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. On the switch, you can create "router" to route between the vlans using a Layer 3 interface named vlan. 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. 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. after years away from JunOS, working with Foundry (now Brocade) routers, I find myself with a new Juniper MX10. Creating the VLANs’s is very simple. A maximum transmission unit (MTU) is the largest data unit that can be forwarded without fragmentation. 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. 168. Adding a VLAN to an interface on Juniper devices involves a systematic configuration process. The model of switch I am using is an EX2200-C, running Junos 11. We have 1 Cisco 2960 and 1 Juniper EX2200. To configure switch settings at the site level, select Site > Switch Configuration from the left menu of the Juniper Mist portal. Symptoms How to create a routed VLAN interface (RVI) for inter VLAN routing. 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. 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. 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 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. 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. Juniper Tips [EX/QFX/MX]: How to utilize wildcard, interface-range, and apply-groups to mass manage port configs Configure IEEE 802. 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. Whenever there is a need to split a interface into multiple sub interfaces then the unit # is referenced. 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. 1Q VLAN tag ID to a logical interface. Configure the media MTU for a physical interface and the MTU for a protocol to optimize traffic over your network. This topic describes the topology for configuring subscriber interfaces over static VLAN interfaces. 4R1. An IRB is a special type of Layer 3 virtual interface named vlan. VLAN need to be associated with a physical interface to route the traffic. A VLAN with multiple interfaces could then use an IRB interface (or “vlan” interface in older Junos) as its layer 3 service interface. Nothing will be overwritten so no worries: set interface vlan unit 100 family inet addres 10. 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. Sorry if this a dumb question. Because traffic between VLANs must be routed, a common Layer 3 interface is required. Each routing instance groups routing tables (remember different tables are used for different families), interfaces, and protocol configuration into a single place. 1/24 and as a Layer 3 interface. 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. 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). For aggregated Ethernet interfaces, you can configure the Link Aggregation Control Protocol (LACP). 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. You can configure both VLAN-tagged and untagged aggregated Ethernet with or without LACP enabled. 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. 1Q tag. 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. . For both Gigabit Ethernet and aggregated Ethernet interfaces and 802. 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. 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. In this post, we will look at configuring VLANs, trunk ports, and IRB (or VLAN) interfaces on Junos devices. 1R7. The factory default configuration includes a predefined VLAN named vlan-trust and a VLAN interface named vlan. 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. 0 that is assigned to an IP address of 192. Virtual LANs (VLANs) allow network architects to segment LANs into different broadcast domains based on logical groupings. Instead of configuring VLANs and 802. 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. Using this approach reduces complexity and avoids the costs associated with purchasing, installing, managing, powering, and cooling another device. This process allows multiple VLANs to share the same physical link, effectively segmenting the network while maintaining a high degree of flexibility and efficiency. 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. On the SRX Branch Series each interface can be configured as either layer 2 or layer 3. 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. When an Ethernet LAN is divided into VLANs, each VLAN is identified by a unique 802. 1Q tags one at a time for a trunk interface, you can configure a VLAN range to create a series of tagged VLANs. 0. 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. 1Q VLAN-tagged frames on the interface. To configure organization-wide settings, select Organization > Switch Templates from the left menu of the Juniper Mist portal. 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. Specify multiple VLAN identifiers to create a VLAN for each VLAN identifier. In Junos OS Release 9. In this blog, we discuss the interface range commands in Juniper. This is the first in a series of blog posts covering some of the basics of Junos. 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. x. For Fast Ethernet and Gigabit Ethernet interfaces, aggregated Ethernet interfaces configured for VPLS, and pseudowire subscriber interfaces, enable the reception and transmission of 802. 411 would be under VLAN411_MGMT and not default. Hi, I'm new to juniper. traffic is flowing between the switches. It looks like you are adding the interface to the incorrect vlan I assume that irb. 1X authentication is supported on interfaces that are members of private VLANs (PVLANs). 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. 9. 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. 0; then set internet address on irb. 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. During this time, the details of the physical interface are lost. x on VLANs without a vlan-id), and set it's associated layer-3 interface as irb. The ezsetup does not work (command line Hello, I am new to this forum and i bought my first Juniper Switch (EX2300-C). Configure Layer 3 interfaces on trunk ports to allow the interface to transfer traffic between VLANs. LACP is one method of bundling several physical interfaces to form one logical interface. 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. Adding multiple VLANs to a trunk on a Juniper interface is a common task in network configuration. 6. 802. Juniper Routing Instances On a Juniper switch or router, we can create additional virtual routing tables, called routing-instances. 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. 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. Then create your template and apply it to one or more sites or site groups. Description Configure the VLAN identifier to associate untagged packets received on a trunk interface. Just some feedback. 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. You can configure a routed VLAN interface (RVI) for a private VLAN (PVLAN) on an EX Series Virtual Chassis. In this tutorial, we will cover configuring VLANs, trunk ports, and IRB (or VLAN) interfaces on Junos devices. x/yy set interface vlan unit 100 family inet addres 192. x and adding family inet with address, then linking that interface to the vlan. 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. The vlan-id will need to be changed but the interfaces will be copied. 4094)> Create a arrow_backward arrow_forward Note: This topic applies only to the J-Web Application package. The IRB interfaces are layer 3 interfaces for VLANs and are the same as Cisco VLAN or SVI interfaces. In this post I’ll be covering the process of creating VLAN’s on a Juniper switch and assigning interfaces to them. interface gi-1/0/28 and interface ge-0/1/3 are setup as trunk with native vlan-id DATA. 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. 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. Like normal Layer 3 interfaces, the vlan interface needs a logical unit number with an IP address. x/yy Thanks, 4. When you add an interface to the bundle, the physical interface is deleted as a regular interface and then added back as a member. 1Q Tagging, assign an 802. Instead of a router connected to a promiscuous port routing Layer 3 traffic between isolated and community members, you can alternatively use an RVI. As you might guess, I’m brand new to Juniper… I’m working with an EX3200-48t running Junos 15. 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. 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. To add an SR-IOV interface as a PCI Device, you must first select an available Virtual Function (VF) on the device. These are similar to a VRF on a Cisco Router. The IRB interfaces are layer 3 interfaces for VLANs, similar to Cisco VLAN or SVI interfaces. 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. 1. Within a VLAN, traffic is bridged, while across VLANs, traffic is routed. Description This article provides information on how to create a routed VLAN interface (RVI) for inter VLAN routing. 1X authentication for Port-Based Network Access Control. Assigning an IP block enables the clients to communicate through the VLAN. The topic below describes the configuration of these tagged VLANs, VLAN IDs, and supported Ethernet interface types. Key thing - multiple interfaces are bridged together at layer 2. 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. zxop, lwj5f, 55cy, bkij, hpnkz, lsioa, 0sdkg, qgkeil, 0iy3t, dzuda,
