1. The EX4200 runs on JUNOS Software, the same operating system software used by Juniper Networks routers to power the worlds largest and most complex networks. * Cisco v irtual P ort C hannel ( vPC) is a virtualization technology, launched in 2009, which allows links that are physically connected to two different Cisco Nexus Series devices to appear as a single port channel to a third endpoint . Each EX4200 switch is capable of functioning as a Route Engine. A little eyeballing and I noticed that connections to port tcp/513 appeared to be constant. The LCD also displays a Virtual Chassis member switchs chassis slot number and Route Engine status for rapid identification and problem resolution. Well check for connections on port 513: show system connections | match EST | match \.513. when two MX run virtual chassis,when the packet traiffic pass the VC, the master router and the backup routerworking by active/active ,or active/standy ? WTF. Omg that worked, Log into sw A and also rename vme interface. High-performance businesses demand high-performance networking solutions. Would I like to do this every day? So look at the other end of that connection (128.0.0.6.1014), and we can see that the session to the master was initiated by 128.0.0.6, which by looking at our handy dandy table ofbme0 information we can identify as being member 1. this port as a standard network port even after you configure it as Below is the configuration from the VC: set virtual-chassis preprovisioned set virtual-chassis member 0 role routing-engine set virtual-chassis member 0 serial-number JW02181xxxxxx set virtual-chassis member 1 role routing-engine set virtual-chassis member 1 serial-number JW02181xxxxx set virtual-chassis member 2 role line-card Solution Increase the mastership-priority parameter of the device that you desire to change to a higher value than that of the current primary Routing Engine. I have four ex-4300 switches configured in a single virtual chassis. Once logged in, you will see the prompt confirming which member switch number you are connected to, and stating that its the master. Once you go virtual-chassis, you dont go back. The hell? is unavailable for use as a standard network port, you can configure The geek ones, that is. If two or more Virtual Chassis ports of the same type and speed However, the router does not apply the configuration What I tried to do initially was to view the connections when I didnt have a console connection to a non-master switch, then connect on a non-master switch console and grab the connection list again. You can initiate a session to the other switches like this: You cant do much on the other switches because they are not the master, but what you can do is to repeat the show int bme0 terse command, and note down the IPs for each member. This thread already has a best answer. [EX] How to recover password and configuration for Virtual Chassis (VC Beyond that, the processturns out to be a little hit and miss.

Description Sometimes it may be observed that a virtual chassis, which consists of two QFX5100 member devices, is not able to reboot either members because of the "ISSU in progress" message. Make sure that you have a connection to the master switch, and that nobody is connected on a console. I want to know is there any differences between mx and ex when use virtual chassis? But now you have a secret nugget of information; the sort of thing you can whip out at geek parties in order to win the respect of your friends. What is a Virtual Chassis and why is it needed - Mist Well the differences between MX and different type of EX platforms can be very radical. The switches support eight QoS queues on every port, enabling them to maintain multi-level, end-to-end traffic prioritizations. when two MX run virtual chassis,when the packet traiffic pass the VC, the master router and the backup router. just verify this via 'show virtual-chassis status'. Example: Configuring an EX4500 Virtual Chassis with - Juniper Networks There is a small difference and that is the failure of the master RE in VC master chassis triggers the failover to the master RE in VC backup chassis. Cloud-Ready EX Series Switches Design Considerations for Virtual Chassis An EX Series Virtual Chassis is a supported combination of standalone EX Series switches interconnected and managed as a single chassis. Check my layer 2 and 3 config, everythings right. I can use that information to figure out what connection has been made, and thus which member switch made the connection but to decode that I need to know the IPs on each switchs bme0 interface. Uplink modules can be installed without powering down the switch, enabling users to add high-speed connectivity at any time or migrate from one uplink type to the other to deliver the ultimate in flexible, high-performance interconnectivity. Interface Card (MPC/MIC) interfaces. the same two member routers in an MX Series Virtual Chassis, the Virtual It turns out that the connections between the switches are in a constant state of flux, and the diff was showing that almost every connection had changed between the two grabs I executed. through theJuniper website that you show ,i have a another question. tcp4 0 0 128.0.0.6.1014 128.0.0.1.513 ESTABLISHED.
