how we can use the frame tagging in the layer to improve the network management and monitoring tasks

 

The data link layer is in layer two in the ISO model. inter VLAN communication frame tagging help identify packets travelling through the network.




When an Ethernet frame traverses a trunk link, a special VLAN tag is added to the frame and sent across the backbone.

We use switches for this and this avoids collision domains and broadcasting collisions.

When packets are arrived to switch frame will be given peculiar number put it like an envelope kind of thing and forward it upward and Takeout give it to end device.
And also we cam Identify and monitor traffic based on channel
We can simply Apply management rules to identify traffic and behaviour of the network
