Which type of traffic flooded on LAN switch when the destination MAC address is not present in the CAM table?
When the destination MAC address is not found in the MAC address table, the switch forwards the frame out of all ports (flooding) except for the ingress port of the frame.
What is flooding in switch?
Flooding. Flooding means that the switch sends the incoming frame to all occupied and active ports (except for the one from which it was received). In essence, flooding is when a switch pretends to be a hub. There are two basic reasons why a switch will flood a frame.
When does unicast flooding occur in a VLAN?
Flooding to all ports in a VLAN always occurs for broadcast frames. If this flooding is happening for unicast frames, network performance might be affected. This issue is known as unicast flooding. Figure 2 Switch Floods Traffic Sourced from PC-A to PC-D to All Interfaces
Why does my Catalyst switch flood my VLAN?
For CatOS-based Catalyst switches, use the following command to display the dynamically learned MAC addresses for a specific VLAN: However, if the frame destination of the MAC address is not yet learned by the switch (that is, it is an unknown unicast), the switch floods the frame to all the interfaces in the VLAN.
How to encapsulate all VLAN traffic inside VXLAN?
Inner VLAN Tag Handling in VTEP and VXLAN gateway should conform to the following: Decapsulated VXLAN frames with the inner VLAN tag SHOULD be discarded unless configured otherwise. On the encapsulation side, a VTEP SHOULD NOT include an inner VLAN tag on tunnel packets unless configured otherwise.
Can a VNI have traffic other than its VLAN?
Neither should a VNI have any traffic other than its corresponding VLAN, nor should a VXLAN interface allow traffic for VLANs for which it is not configured. You really, really don’t want frames with any VLAN tag coming into the access interface Ethernet 1. That could lead to security problems like VLAN hopping.
