Gns3 linux duplicate packets tun012/6/2023 On switches that display this behavior, it can be induced by clearing the MAC forwarding table (on most Cisco switches, the privileged command “clear mac address-table dynamic” will accomplish this). The duplicated packet behavior is switch dependent, some switches exhibit this, and some do not. Since the interfaces attached to the bond may occupy multiple ports on a single switch, when the switch (temporarily) floods the traffic to all ports, the bond device receives multiple copies of the same packet (one per slave device). Initially, the switch does not associate the MAC address in the packet with a particular switch port, and so it may send the traffic to all ports until its MAC forwarding table is updated. This is not due to an error in the bonding driver, rather, it is a side effect of how many switches update their MAC forwarding tables.

Inet6 addr: fe80::250:56ff:fea9:3c/64 Scope:Link This method requires that you have a good working knowledge of the Linux command line, as you will have to work with network attached storage, and manually copy. I am positive it is not a hardware issue.Eth0 Link encap:Ethernet HWaddr 00:50:56:A9:00:3C Tested with multiple interfaces including 10G, 1G Ethernet interfaces and VMware virtual interfaces and loopbacks. The GNS3 VMs were hosted even on a server with 16-core Xeon/64GB RAM. The cloud can handle it with no problems. Transfer speed = 20 to 70Mbps depending on the CPU resources given to the IOU and the VMs. Here is a file transfer made through a cloud hosted on Windows 10 with GNS3 153: Here is the same test from cloud hosted Ubuntu 16.04.2 and GNS3 200rc1: When using cloud hosted on GNS3 VM 153 or 200rc1: This was tested using a simple topology a shown below. The cloud only works properly when it is hosted on Windows with GNS3 153. There must be some problem with the uBridge on Ubuntu systems. I also see a lot of jumbo packets despite the fact that MTU on all interfaces is set to standard 1500bytes. When I check the packet capture, I see a lot of re-transmissions and duplicate packets none of which actually makes it to the other side of the cloud. However, when I try to transfer a file using FTP, SMB, HTTP or any other protocol, the transfer speed never goes above 1kB/s. More specifically, they do work for small traffic such as ping and loading of simple websites. I have found that the clouds hosted on all GNS3 VMs (153-200rc1) and Ubuntu16.04 do not work. I have tested on multiple PCs, laptops, servers with different versions of GNS3 from 153 to 2.0.0rc1. I have spent the past few days testing GNS3 clouds extensively.
