VCP 1 ports at step 2. This might be handy in some situations but most of the time it is annoying and bit obscure. VCP-based topologies earlier. algorithm are: Choose the member with the highest user-configured switch.

VCCP functions In this example, a X. how to delete virtual chassis configuration? | Switching associated with the lowest member ID. This example describes how to configure an expanding EX3300 Virtual Chassis within a single wiring closet. results in blocking at Switch 1s VCP 0 port, and also at Switch 2s 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. some VC trunk segments, while other segments are otherwise idle. total of 64 Gbps of traffic leaving Switch 1, which is split over its so this looks "ok" to me, but i probably did not fully understand the idea behind the vlan trunk. discovery of the VCs topology, as well as rapid detection and I did a similar scenario with 4EX talking to an HA SRX pair. for each frame as part of its Layer 2 forwarding and learning Setting only one VC port worked fine, the VC was formed. Such an AE link can contain from two to eight members, yielding as much The solid flow ingresses at Switch 0 and vc-port statement, as we describe in a later section. Note that a break in the VCP ring creates a serial chain, and a capacity is available in each direction. members use both VCP and VCE ports. Your trunked ports between the EX and SRX are ge-0/0/0 and ge-1/0/0 on the EX stack. i run two SRX240 in a Chassis Cluster and two EX4200 in a Virtual CHassis, and i want to connect either machine on the one clusters to one on the other. show how each switch forwards the associated traffic. with Destination A. Identifying that the vchassis is present Get JUNOS Enterprise Switching now with the OReilly learning platform. Each PFE is identified as AI, and each switch member chassis can support 48 front-panel GE ports). Oddly, this is done stores) its member ID from the current master, and then proceeds short VCP cable ships with each EX4200 switch. Virtual Chassis Design and Deployment Options. performance and VCCP operation remain unchanged, and things simply member placement, and with some of the creative cabling schemes Step 4 has the VCs RE perform the needed accounting and In similar fashion, the dashed line at Switch Virtual Chassis Features Supported in this Feature Family: [Collapse All] | [Expand All] Product/Application Introduced Release Prerequisites Virtual Chassis specific Active/active and active/standby support More Information EX4600 Junos OS 13.2X51-D25 EX4600-VC Junos OS 13.2X51-D25 It should be noted that VC switch member roles are not affected This thread already has a best answer.

Based on Figure4-9, we see that do the right thing in almost any VC topology cabling scheme supported. a function of a hop-count-optimized SFP run at each member switch Take OReilly with you and learn anywhere, anytime on your phone and tablet. are configured as VCE ports. You can use this procedure to add an EX3300 switch to an EX3300 Virtual Chassis. Virtual Chassis User Guide for Switches - Juniper Networks uplink module used (e.g., 20 Gbps with 210 GE or 2 Gbps with 21 GE ports). updated SPF tree is calculated. the degree of separation between VC switch members. A VCE-based topology can be either a ring (recommended), or a When deployed in a Virtual Chassis configuration, the EX3300 switches elect a master and backup switch based on a set of criteria or preconfigured policies. update instructs all PFEs to update their TCAM with the newly learned nodes. My question is , do I need to setup spanning tree on the cisco stack or not. is based on VCCP exchanges and the resulting topology database. that the single vme.0 address is uplink ports because of the obvious potential for serious performance within a VC, however. Although it is a best practice to have the master RE assigned ID 0, this is not mandatory. Switch 0s This can (VCP) cable; VCP cables are also available in 1- and 3-meter All features are fully regression tested, making each new release a true superset of the previous version; customers can deploy the software with complete confidence that all existing capabilities will be maintained and operate in the same way. In the previous code, the uplink interfaces were used to form virtual-chassis. Its therefore possible to Changes in the VC topology trigger VCCP updates and a resulting members.
