WebThe IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as “tags,” and multiple VLAN IDs are thus referred to as a “tag stack.” Tag stacks allow L2 tunneling and the ability to segregate traffic within a particular VLAN ID, among other uses.

WebVLAN Frame tagging is a technology which is used to identify the VLAN that the packet belongs to. The VLAN Frame tag is placed on the Ethernet frame when the Ethernet frame reaches a switch from an access port, which is a member of a VLAN.If the switch has a trunk port, the Ethernet frame can be forwarded out the trunk link port.This enables … WebThe tags work for some layer-2 LAN protocols, e.g. ethernet, but UDP is a layer-4 protocol, and it is blissfully unaware of layer-2. Also, unless your ethernet switch is configured to use the tags and has trunks configured on interfaces, the priorities mean nothing, and they are stripped at layer-3 (e.g. routers). – holiday inn french quarter tripadvisor https://iconciergeuk.com
