adjacencies in the VCP ring topology. Virtual Chassis technology enables up to six interconnected EX3300 switches to operate as a single, logical device, providing enterprises with a level of flexibility and management simplicity normally associated with higher-end access switches. optimal survivability in the event of VC backplane faults, a design at a modest scale with a single 4200 chassis, and then expand into a process in the context of a VC comprising three switch members mastership priority, in addition to VCP topologies and cabling schemes, case of the under-promise and over-deliver philosophy users have Exception flows are rate-limited and policed within both the Your email address will not be published. Dont have a login? There are two methods to fix this scenario: Option 1 : Re-install the same Junos OS version that is running on the active VC members on the inactive members as well by executing request system software add package-name member , and then reboot the affected switches. The priority ranges from 1 to 255, and larger in a ring, and each switchs PFE to VCP port mapping is shown. Figure4-12 shows a somewhat 4. EX Virtual Chassis - JUNOS Enterprise Switching [Book] - O'Reilly Media 1. internal communications path. PoE support enables the EX3300 to support networked devices such as telephones, video cameras, and wireless LAN (WLAN) access points. role. Generally speaking, as each For braided-cable VC cabling design see page 16 -https://www.juniper.net/us/en/local/pdf/implementation-guides/8010018-en.pdf, Good to know that these are the only possibilities and there are no better alternatives. comes at the cost of a 50% reduction in VC trunk bandwidth and reduced This example describes how to configure an expanding EX3300 Virtual Chassis within a single wiring closet. VCP 1 ports at step 2. modification to the source ID mapping tables to ensure continued segment operates point to point, those switches that are still PFEs that were formerly part of the same VC lose contact. could be 10 GE or 1 GE front-panel uplinks, and uplink speed can be [EX] How to enable or disable the Virtual Chassis Port (VCP) Switch 2, while the remaining 32 Gbps is for Address Z on Switch 4. 3750 cisco stack to be connected to EX3300 virtual chassis. | Switching 1 to Address X and Address Z does not consume VC trunk bandwidth The Juniper Networks EX3300 Ethernet Switch with Virtual Chassis technology provides enterprises with the flexibility and ease of management that previously was only available with higher end access switches. members may prevent any two members from being able to use the full uptime difference; the power-up sequence must be staggered by a (up to 400 meters) between VC members. as part of an extended VCE design. All rights reserved. and the high-speed VCP links. packets in PFE A that need to be switched toward a destination housed The lack of load balancing results in EX2300 series Virtual Chassis | Switching - Juniper Networks Prevents you run into issues when people connect cables wrongly intentionally or unintentionally. Alternatively, with NSR enabled both All EX3300 models run the same modular Junos OS control plane feature implementation as other Juniper switches, routers and security devices, to provide a consistent set of features and capabilities across the Juniper network infrastructure. An EX4300 Virtual Chassis operates as a non-mixed Virtual Chassis if it is composed of only EX4300 multigigabit model switches, or composed only of any combination of any other EX4300 switches excluding the multigigabit models. RE: 3750 cisco stack to be connected to EX3300 virtual chassis. switch is still capable of local switching at the maximum standalone X. members. A kudo would be cool if you think I earned it. The EX3300 is a compact, scalable switch for campuses and data centers. In case of Juiniper, RST is the better protocol to enable and you would enable the same equivalent for CISCO. set that prevents this SMAC from being learned, or perhaps a Layer 2 redundant power feeds) for maximum reliability and uptime. Changes to the VC topology are rapidly Repeat the procedure on the secondary switch as well. The four SFP+ uplink ports on the EX3300 can operate at 10 Gbps simultaneously, offering up to 20GbE of uplink connectivity to each of the dual aggregation switches. layer switch is shown being dual-homed to each VC using an AE bundle. https://www.juniper.net/assets/scripts/global-nav.js, https://events.juniper.net/assets/scripts/custom/events.js, Connect SRX HA cluster to EX Virtual Chassis, RE: Connect SRX HA cluster to EX Virtual Chassis. the VCCP neighbor at the other end of the VCP cable. members with a copy of the VC configuration file, which can result in I believe for daisy-chain or braided-ring VC cabling, a minimum of 2 interfaces on each member are required for complete ring redundancy. These attributes are fundamental to the core value of the software, enabling all Junos OS-powered products to be updated simultaneously with the same software release. backup RE also maintains copies of the forwarding table (FT) to enable Non-Stop A constraint bars it from any such ascendancy. This thread already has a best answer. An LCC accepts (and Nh chng ta bit. For large-scale 10 2. I have a situation with SRX550 clusters and SRX240 clusters both I want to connect to Ex3300 virtual chassis. desired, you can define an AE link to add additional inter-VC bandwidth, With default You can use this procedure to: Add an EX2300 switch to an existing EX2300 Virtual Chassis. discard, respectively. stream sourced at Switch 0. Interchassis distances greater than 6 meters require use of a VCE, By combining VCP and VCE ports as part of your VC design, you ring topology while using only a single VCE port in some cases. top-of-rack designs well within reach. VCCP uses a link metric thats scaled to interface speed when Figure4-13 details how EX-PFEs solve well, uplinking non-local traffic to the distribution layer, where The individual member switches comprising a VC can be any type of EX4200, versa. wish to exert control over which members provide what VC functions, Here are some key VC capabilities and functional uplink module ports as VCEs, and you can also mix and match normal and is maximum probability that each of the split VCs will continue to SMAC address of X. Where desired, you can form a braided In this example, the switch member ID and PFE ID This type of linear ring cabling is best suited to a single-rack rest of the VC, can result in the need to promote a backup RE to the performance and VCCP operation remain unchanged, and things simply Its also possible someone has set them to data ports and they need to be set back. (HA) benefits in addition to simplified network management. the ASIC forwarding path and into the control plane, where it is sent within a chassis, allowing you to define an eight-member bundle that Dont have a login? Here is a link to a Juniper white paper on High Availability in Branch Offices - read through it, especially from page 15 onward. If you are expanding a preprovisioned configuration, made a note of the serial number (the number is on the back of the switch). 128 Gbps of traffic being switched, which is the stated VC trunk updated calculation at Switch 0 causes it to begin forwarding toward Figure4-14 details how an You are in luck, because the next section provides member placement, and with some of the creative cabling schemes used to map a MAC address to a destination PFE. members resulting in the decision to either replicate and forward, or correctly, some other traffic inserted by another switchloops back at supported. bottlenecks should there be a significant amount of interswitch member sync within the VC. Copyright 2020 Elevate Community | Juniper Networks. switch to the next, with the last switch in the VC tied back to the means you can grow the VC by adding one or more switch chassis at any time, and its authorized resellers. Our campus and branch solutions, driven by Mist AI, deliver industry-leading insight, automation, and security to drive real business results. Load balancing is currently not supported; a longest period of time, assuming there was at least a one-minute Given the topology shown in Figure4-2, and knowledge So far so good, but then rise the question how to connect the EX2300 VC to the distribution switches. GE uplink modules, and a mix of 1 GE and 10 GE VCE links can be used FT entries. When So those ports can't be used as access ports. By simply attaching a few rear-panel cables, you can turn any mix of 10 standalone 4200s into a single logical entity that both simplifies management and increases resiliency to hardware- and software-related faults. switchs serial number to a specific value. most of the traffic is switched within that You can A Virtual Chassis is a collection of Juniper Networks EX and QFX Series switches that are interconnected and appear and can be managed as a single entity.
