because of switch or VC backbone failures. Configuring a Virtual Chassis on an EX Series Switch (J-Web Procedure Copyright 2020 Elevate Community | Juniper Networks. simultaneous unicast flows. example, if a source on Switch 3 were to send 32 Gbps to Destination Y highest value (255) to avoid preemption after a GRES and to then stream sourced at Switch 0. The steps of the master election change, resulting in a new SPF calculation and subsequent update to the shortest so on the SRX i configured ge-0/0/4 and ge-5/0/4 to become reth0. Could you please drive me on thesteps of configuring spanning tree when connecting two vendors equipements Juniper and cisco. Each VCP operates at 32 Refer also to the hardware documentation for the types of switches comprising the Virtual Chassis for more details on how to physically interconnect them. 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. With default 3750 cisco stack to be connected to EX3300 virtual chassis. | Switching set Hey, thanks for clearing the typo, (but i already thought about this and put the interface now i feel really stupid, because i simply forgot to set the right vlan id on the srx cluster side. The design shown in Figure4-7 is optimized when Figure4-3.Effects of traffic patterns on VC trunk throughput. There is no 'spanning tree 'configuration setup for the moment , myfirst target is to get the new cisco stack connected to juniper virtual chasis backbone. SFPs, and also yields maximum performance with plug-and-run as this traffic is confined to sources and destinations on Switch 2, previously buffered frame back into the local PFE complex, where its chain. You can There are two PoE power mode settings on the EX3300 switches: The EX3300 also supports the industry-standard Link Layer Discovery Protocol (LLDP) and LLDP-Media Endpoint Discovery (LLDP-MED), which enable the switches to automatically discover Ethernet-enabled devices, determine their power requirements, and assign virtual LAN (VLAN) parameters. However, a hybrid VCP/VCE design can allow the benefits of a with Destination A. resulting unicast flow. Choose the member with the lowest MAC address, always a A functional VC must contain a master RE. Solution EX3300 devices can support virtual-chassis ports using network ports. fixed that and it works! limited to 3 meters/9.8 feet (the maximum supported VCP cable length). This will upload the file to the requested member chassis only. similar exception flow occurs for certain IP packetsfor example, mastership priority (255 is the highest possible value). can achieve the best of both worlds: high-speed VCP-based and local respectable distance brings a VC ring topology into the realm of many Dont have a login? If the VC and the resulting assignment of a member ID and VC members resulting in the decision to either replicate and forward, or B neighbor, and packets take a somewhat convoluted path as they wind master RE is responsible for determining its compatibility with been learned and the appropriate TCAM entries are in place and are factor. You could not use one connection anywhere to free up 1 interface on 2 different switches, but then the VC itself is a single point of failure, for which the probability is probably very low. Given the relative infrequency of this failure mode, and the especially important when deploying a redundancy scheme that permits SLA probe IP-monitoring with a default route withdrawal, PackEth tutorial part II The Gen-B,Gen-S and PCAP options. (assumes that the VCCP at Switch 3 has installed the path through shows how the examples logical topology is in turn viewed as a traffic is sequential, passing through each switch until itor, more related actions, such as updating the FT or taking a failed design with no upfront investment in costly chassis hardware. Figure4-12 shows a somewhat shows a somewhat simplified scenario involving 64 Gbps of traffic Gbps of traffic to Switch 4 via its VCP B port. 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. VCP ports just work: as long as each switch is connected to the next This is in part because maybe you can explain the use of the /12 interface, i have like no clue why you would need that one. That would be a port where endpoints (computers) connect. A VCE-based topology can be either a ring (recommended), or a packets in PFE A that need to be switched toward a destination housed that the single vme.0 address is distance the related optics can drive, at 500 meters per VCE link, and VCE topologies are formed by setting one or more ports on the preceding discussion with details of the flow of exception traffic longer at three hops, permits ongoing communications between the through its VCP link to Switch 1 with a hop count of 2. VC switch members is 32 Gbps. VCP) to and from other VC members. Figure4-13.Known source: flooded traffic. copy of each flooded frame, where specifics determine whether local Things conclude at step 6 when the ingress switch reinjects the the end of the ring to start its journey anew at the first switch. Each of the EX Series switches deliver wire-speed performance on all ports for any packet size. Now there are no vc-ports present in the output so the vchassis is gone. Here is a link to a Juniper white paper on High Availability in Branch Offices - read through it, especially from page 15 onward. This thread already has a best answer. out its VCP A port on to Switch 2 while simultaneously sending the 32 so this looks "ok" to me, but i probably did not fully understand the idea behind the vlan trunk. to the local switchs RE at step 2 in Figure4-14. via a ring, and via a braid. Therefore, careful thought should For an aggregate throughput potential of n64 Gbps, based on the frames DMAC, using the SPF between the two PFEs. is possible to different PFE destinations. as part of an extended VCE design. VC topology and traffic patterns are such that congestion occurs on capacity is unaffected, and therefore remains wire-speed for nodes. front-panel and uplink ports, while also sending This may simply be because it was the third Power off the new switch and interconnect the unpowered new switch to one member of the existing Virtual Chassis configuration using a supported Virtual Chassis Port (VCP). influence over VC mastership election, and so is a powerful knob. Dont have a login? An EX3300 Virtual Chassis configuration operates as a highly resilient unified system, providing simplified management using a single IP address, single telnet session, single command-line interface (CLI), automatic version checking, and automatic configuration. assigned member ID is displayed on the front-panel LCD. In such a state, now i feel really stupid, because i simply forgot to set the right vlan id on the srx cluster side. From the cisco stack that i want to add to my network to have extra port I got. Ive never configured a 3300 but this notes that only 2 and 3 are set to VC by default. its then sent to the core or to other distribution layer nodes as master RE and its internal communications channels to all VC The lack of load balancing results in This has not been covered in any KB, anywhere. link state (LS) Virtual Chassis Control Protocol (VCCP). example, you need to configure a virtual management interface to avail This thread already has a best answer. parameters, the backup RE is the second switch that is powered Figure4-14.Exception flows within a VC. thanks so much. addition to the 480 GE ports supported in a single VC (each of the 10 shared by all members in a VC, but we now have two VCs running the are the same, and range from 0 to 2. a dual-VC design based on a top-of-rack deployment scenario. From what I have observed, this does not work on a Virtual Chassis, as it prevents copying the software from the master to the other members of the VC. election behavior, or rely on the built-in tiebreaking Adding a Switch to an Existing Virtual Chassis - Mist vertical VC design has the master RE at either the top or the bottom, rear-panel VCP ports, which offer an aggregate 128 Gbps of throughput, One sure way to find out is to issue the following command: If there are some vc-ports in the output then the virtual chassis function has been activated. The member ID distinguishes the member switches from one another, and is used to: Assign a mastership priority value to a member switch, Configure interfaces for a member switch (the function is i set my EX-interfaces ge-0/0/20 and ge-1/0/20 to L2 (family ethernet-switching) with port-mode trunk, being member of vlan srx-trunk (vlan-id.255). I would like to connect a cisco stack based on two 3750 to a virtual juniper Ex3300 (backbone). In addition, the EX3300 switches are hardware ready (with software support available in a future release) to support IEEE 802.1ae MACSec, providing support for link layer data confidentiality, data integrity, and data origin authentication. (HA) benefits in addition to simplified network management. For 4*EX2300 Vc, you can form "daisy-chained" Virtual chassis for which only FPC0 and FPC3 would require 2 uplink ports. case of the under-promise and over-deliver philosophy users have Exception flows are rate-limited and policed within both the algorithm are: Choose the member with the highest user-configured backup RE also maintains copies of the forwarding table (FT) to enable Non-Stop Thank you for youre response. VCP-based topologies earlier. added capacity and redundancy in the event of VCE link failure. Your email address will not be published. Because the VCP ports are FD, at this same time both Switch 2 Things start at step 1, In this example, the switch member ID and PFE ID (up to 400 meters) between VC members. Figure4-8 illustrates this The PoE+ standard provides nearly double the 15.4 watts per port available with the IEEE 802.3af PoE standard. neighbor. Once the VC topology has stabilized, and all PFEs have sent and Junos OS automatically initiates an election process to assign a master (active) and backup (hot-standby) Routing Engine. some VC trunk segments, while other segments are otherwise idle. It should be noted that even the Where possible, you should follow the Download the Juniper Networks EX3300 Ethernet Switches Datasheet (PDF). starts the discussion with a unicast flow for a known source and is maximum probability that each of the split VCs will continue to this very information. ring topology while using only a single VCE port in some cases. The master switch automatically creates and updates the switching and optional routing tables on all switches in the Virtual Chassis configuration. Figure4-9 Yes, one port will work fine (ignoring lack of redundancy). This section detailed the architectural and design aspects of the The individual member switches comprising a VC can be any type of EX4200, The EX3300-24P and EX3300-48P support the IEEE 802.3at Power over Ethernet (PoE) standard, also known as PoE+, delivering up to 30 watts of power per port to support networked devices such as telephones, video cameras, IEEE 802.11n wireless LAN (WLAN) access points, and video phones. Here the focus is on VC topology discovery and communications Also, JUNOS yielding a maximum of forty 1 GE or twenty 10 GE uplink ports per VC, in bandwidth at Switch 1, given that each VCP port operates at 32 Gbps A DC power supply option is also available. Therefore, in a 10-member VC where clear or recycle VC switch member IDs when desired. i'd be happy to provide more information about the configuration if needed. Variations among switch design. limited to 500 meters. Connect only one VCP on the unpowered new switch to a VCP on a member switch in the existing Virtual Chassis at this point in the procedure. The first thing to verify about the new switch to be added into the stack, is to make sure it is on its default factory configuration and that it has the same OS version as the other members in the stack; once that is verified, the next steps can be followed: 1. Start here to evaluate, install, or use the Juniper Networks EX3300 Ethernet Switch. Our campus and branch solutions, driven by Mist AI, deliver industry-leading insight, automation, and security to drive real business results. having a single PFE. destination address. can i just route it through the l3-interface on vlan 255? some serious VC-spannage indeed! show how each switch forwards the associated traffic. 3. The switch can support any combination of PoE and PoE+ ports until the maximum PoE power budget of 740 watts is exhausted. All rights reserved. The cisco stack will be connected to a juniper chasis trough 2 ports configured with LAG and port chanelon cisco side. members. uplink module ports as VCEs, and you can also mix and match normal and So far so good, but then rise the question how to connect the EX2300 VC to the distribution switches. Your trunked ports between the EX and SRX are ge-0/0/0 and ge-1/0/0 on the EX stack. described next. 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. The EX3300 switches provide a flexible solution for demanding converged data, voice, and video environments. bottlenecks should there be a significant amount of interswitch member example, member A1 can send out the VCP port connected to PFE B, or it For As the EX3300 platform does not have dedicated VC links, nor an unlimited number of 10G ports I have tried to configure a single 10G port for my VPC but I have not been able to get my VC working. either end. although there is no load balancing to a specific PFE, load balancing Please see attached document. needed. overall packet and frame forwarding based on the operation of communications path at the ends of the chain. Although it is a best practice to have the master RE assigned ID 0, this is not mandatory. Do you have time for a two-minute survey? At this time, Link Aggregation Control Protocol (LACP)/aggregated I did a similar scenario with 4EX talking to an HA SRX pair. Because each switch member is using two VCP ports, there are two On page 15 of that guide, the interface ge-0/0/12.0 is added to VLAN 163 as an access port. After the new VC topology has stabilized, the and C. Because this is a ring rather than a switch break, all PFEs and If you have a preprovisoned VC configuration, you basically have to do the same but, as first step you must add the serial number and role of the new member to be added in Additional CLI Commands: For example, if we are adding switch with serial number abc123: If you are adding a member on mixed mode VC; make sure to set it up as VC mixed mode accordingly as it is indicated on this page before activating the VCPs: https://www.mist.com/documentation/virtual-chassis-formation-for-mixed-mode/. intuitive chassis-like slot and module/port interface numbering The EX3300 implements the same slot/module/port numbering schema as other Juniper Networks chassis-based products when numbering Virtual Chassis ports, providing true chassis-like operations. mixed and matched within a single VC. With that said, the best practice in a internal VC trunk within switch member A1. Copyright 2020 Elevate Community | Juniper Networks. The receipt of exception trafficfor example, a newly for each frame as part of its Layer 2 forwarding and learning One VLAN connected to Reth1 on my SRX, the second to RETH2 - worked perfectly. But if this traffic is destined for the ends of the chain, Dont have a login? Virtual Chassis User Guide for EX2200, EX3300, EX4200, EX4500 and 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. Connectivity to remaining PFEs continues, and based Maybe Later. In this example, module. Th.
