Abstract
Provided are methods, non-transitory computer-readable medium, and network devices for duplicating network traffic through transparent VLAN flooding. In some implementations, a network device comprises a plurality of ports. The plurality of ports may include a first port configured as a receiving port for a VLAN configured for the network device. The plurality of ports may further include a set of ports configured as I/O ports of the VLAN. MAC learning may be disabled for the receiving port. In some implementations, the network device is configured to determine, based on contents of a packet received at the receiving port, that the packet is to be sent to one or more monitoring devices. The network device may further be configure to, upon receiving the packet at the receiving port of the VLAN, cause a copy of the packet to be sent to each of one or more I/O ports of the VLAN.
