The collision propagates through the entire network, meaning that the LAN is busy and requires users to wait until the collision has been fully transferred throughout the network before it is operable again—at which point the original data must be resent. VLANs reduce the incidence of ...
VLAN1 has a very special meaning, it is the vlan used by many L2 protocols like for example CDP and, VTP, those protocols always send their frames untagged on VLAN1 by default, that does not mean that you cannot change the native VLAN from VLAN1 to any other vlan, instead, it is ...
Meaning only one SVI can be mapped to a VLAN. The default is VLAN 1, which is mapped to interface vlan 1 on both Layer 2 and Layer 3 switches. In Layer 2 switches we call this VLAN the management VLAN and it is used for remote switch administration. An SVI will not be active until...
As I stated in my previous post, there is a one-to-one mapping between SVI and VLANs. Meaning an SVI can only be associated with one VLAN. While you can create more than one SVI or physical router port to belong to the same subnets as the VLAN SVI, the SVI will only be associated...

However, on some switches you have VLANs that are local to each port, meaning VLAN 123 on port 1 is not in the same flooding domain as VLAN 123 on port 2. In this case you'll map the two VLAN instances to two different VXLANs/VNIs. On a 48 port switch, you will in theory get...
