![]() ![]() The switch is trunked to the MX on interface ae0. As you mentioned, configure your interface as layer 2 to see if your carrier's MAC address shows up. Servers are connected to a switch on VLAN 185. Configure interface-level packet-capturing ( and look at the capture offline. Youâll need to bridge a standard VLAN with a VXLAN VNI. ![]() Broadcast and Multicast traffic is flooded to all VTEPs. Once it gets a packet from a particular MAC address, it will store that MAC address against the VTEP in its table and only send subsequent packets to that address. If a MAC address is not found in its table (show ethernet-switching table) then it will flood the packet to all statically configured VTEPs. #Juniper how to check mac address on mx manualJuniper MX manual VXLAN implementation uses flood-and-learn to discover MAC addresses. In my case, I wanted to create an L2 circuit from a firewall, across The Internet, to a Linux based router. The Internet) then a simple static configuration is quick to do. However, if youâre doing something small such as wanting to span an L2 link across an å network (e.g. You probably want to be a bit careful creeping much past this if you want to push bits for a long amount of time as this traffic is generated from the internal em0.On most VXLAN deployments, youâll want to be using EVPN to distribute MAC addresses between devices. Now, if you execute the above command 25 times, I found this generates about 850Mbps of traffic. Doable - Id get the mac-address from the table for that vlan or port, and copy paste the OUI mac-address into the command. I dont want to map each mac address as that will be a lot of manual work. I want to wildcard after the first 6 Hex characters, but that is not allowed. Exit 2 ping -Jr -c 500 -s 65000 -F 1.1.1.1 -JU LINKTEST 1.1.1.2 > /dev/null Line Cards and Modules To provide the high-density and high-speed Ethernet services, a new type of Flexible Port Concentrator (FPC) had to be created called the Dense Port Concentrator (DPC. Example: Ports xe-0/0/0 or ge-1/0/8 will only allow Siemens phone OUIs. If you want to see the MAC table specific to some interface, you can use the command show vpls mac-table instance match ' MAC learning in VPLS is only data plane based. + Running ping -Jr -c 500 -s 65000 -F 1.1.1.1 -JU LINKTEST 1.1.1.2 > /dev/null To check the MAC table VLAN specific, use the command show vpls mac-table instance vlan-id .I thought it was a great idea â and now Iâm sharing it with start shell Since this wasnât quite enough traffic â a suggestion (not mine) was to drop into the shell and queue up a bunch of jobs to do the same thing. Increasing your ping size, obviously results in a larger amount of data being dropped on the link per ping. By using rapid â youâre forcing the ping to continuously send traffic before the previous request has expired, effectively doubling the amount of data on the link. In practice â this command netted about 67Mbps of traffic dropped onto the link, looping about until the TTL expired. * this must be the MAC address of your local interface so youâll accept the traffic */Īrp 1.1.1.2 mac ping 1.1.1.2 source 1.1.1.1 routing-instance LINKTEST size 65000 count 200 rapid ![]() Interface show configuration interfaces xe-2/1/3 I modified this somewhat in that I created a routing-instance type virtual router, placed my interface in that routing-instance and performed the tests noted above so that youâre not mucking about in the default routing-table should you mess something up with your IP allocation, show configuration routing-instances LINKTEST You can follow the steps outlined here to generate some traffic. We probably want to generate some traffic to determine if any of the equipment involved in the loop is responsible for that pesky CRC youâre trying to find. So youâve been receiving errors on your Juniper router, and asked your local provider to drop a loop on the cable facing your box at some point in the cable run in order to divide and conquer. ![]()
