Oct 18, 2023 · I seem to be finding two approaches to configuring VLAN tagging on the RETH interfaces, and I'm confused as to which is best practice. You can add multiple vlans on the ports and can also configure it as a trunk instead of access. 4 access ports, 1 trunk port, with an IRB in one of the VLANs (intended to manage the switch in-band), using a native-vlan on the trunk port (for the management VLAN): also in each virtrual switch, i created a bridge domain without any vlan id, with one laye-2 port assigned. Jan 11, 2020 · [edit interfaces ge-0/0/1 native-vlan-id] 'native-vlan-id 12' native-vlan-id can be specified with flexible-vlan-tagging mode or with interface-mode trunk So, what's the right way to do this? I'd rather not set up the SRX port for ethernet-switching and need to configure IRB ports if I can avoid it, but I'm not sure how to get around this. 1Q VLAN-tagged frames on the interface. So that’s why I’m trying to recreate the configuration from the previous switch. Symptoms. e. in order for the above trunk link carrying native vlan id, i assigned a native vlan id for the trunk link: ge-3/3/9 { flexible-vlan-tagging; native-vlan-id 101; encapsulation flexible-ethernet-services; unit 0 { family bridge { interface On MX Series routers, you can configure a trunk interface on a bridge network. Instead of configuring VLANs and 802. If your device supports "flexible-vlan-tagging", I'd suggest you to use this one instead of "vlan-tagging", as it provides more flexibility. You can have tag ports. Jun 7, 2015 · To create a trunk port you need to set that port to tagged. Hello Rene, in addition to smelnik's answer, some devices support only "vlan-tagging" (like legacy EX series), and some devices support both. And I would use flexible-vlan-tagging. For Fast Ethernet and Gigabit Ethernet interfaces, aggregated Ethernet interfaces configured for VPLS, and pseudowire subscriber interfaces, enable the reception and transmission of 802. These will then all have matching tags to the ones setup on the Oct 24, 2017 · Description. 1Q VLAN tags, include the vlan-tagging statement at the [edit interfaces interface-name] hierarchy level: but my trunk seems to work perfectly without it.

This topic explains the following concepts regarding bridging and VLANs: Jun 4, 2021 · If the device needs multiple vlans like a VMware server the procedure requires using vlan tags. To configure a device to receive and forward single-tag frames with 802. You configure the vlan first then add it to the interface. Juniper only supports 802. Oct 18, 2023 · I'm moving a pair of SRX340 devices from using individual physical ports for each connected service to LACP trunks. SRX has two kinds of L2 modes: Switching mode Access vs. Multiple layer 3 interfaces are then assigned to each of these vlans. Mar 30, 2008 · The ports or interfaces on a switch operate in either the access or trunk mode. On the server or device you configure all the vlan tags needed. Difference being vlan-tagging allows you to use single tags. From configuration mode, create the VLAN and add access vlan members to it: ELS EX and QFX devices: root> configure I think you should get a commit error if you try to configure 'vlan-tagging' on an interface set for family ethernet-switching. 1Q VLAN single-tag and dual-tag frames on logical interfaces on the same Ethernet port, and on pseudowire logical interfaces. Here is how it works: MGMT is NOT a member of trunk, but it is a member of native VLAN: However, when I attach the WAP to the Juniper switch on an interface with VLANs 10, 15, and 30 all tagged (trunk interface), it cannot get out to the internet. Is the only difference between an access port and a trunk port the "native-vlan-id" command? May 22, 2010 · The EX switch will tag and transmit the MGMT packets. This article explains each method. Your switch will not add or remove the tag. The topic below describes the configuration of these tagged VLANs, VLAN IDs, and supported Ethernet interface types on SRX Series Firewalls. Virtual LANs (VLANs) allow network architects to segment LANs into different broadcast domains based on logical groupings. This article provides an example for how to configure SRX to translate VLAN ID. The information below describes the Access and Trunk port modes and the differences between them. The VLAN tag is a 4-byte tag inserted into Ethernet frames with a maximum size of 1522 bytes, and is used to consistently associate traffic with a particular Feb 20, 2008 · The purpose of this article is to explain how to configure VLANs and trunks on the EX Series (Enhanced Layer 2 Software (ELS) and legacy) Switches and QFX devices, and verify that they are created. All other port in that Vlan are untagged. Trunk. 1Q standard for VLAN trunking, whereas Cisco has it’s own proprietary trunking protocol ISL (Inter Switch Link) as an option on some of it’s switch models. 1Q tag.
