What is the effect of creating separate VLANs?
VLANs can help manage broadcast traffic by forming multiple broadcast domains. Breaking up a large network into smaller independent segments reduces the amount of broadcast traffic each network device and network segment has to bear.
What is the most common cause of a VLAN mismatch?
A VLAN mismatch occurs when two connected switchports have different VLAN configurations. For example, switch 1 port 1 is configured for native VLAN: 1, allowed VLANs: all. This port connects to switch 2 port 48 which is configured for native VLAN: 1, allowed VLANs: 1 and 2 only.
How do I assign a VLAN to a computer?
Here are the steps to set a VLAN (Virtual LAN) ID on a network adapter in Windows 7:
- Right click on Computer > Click Properties.
- Click Device Manager.
- Expand Network Adapters.
- Right click on the adapter you want to set the VLAN for > Click Properties.
What happens when a VLAN is deleted or added to a network?
Each time a VLAN is deleted or added on a switch, the config revision number is increased. The addition of a switch to a network within a VTP domain can cause lost connectivity across that network. This happens because the newly introduced switch has a higher config revision number than that of the VTP domain.
What does the default VLAN mean on a switch?
Default VLAN: This can refer to one of two types. Typically, the default VLAN refers to the one that all of the ports on a device belong to when it is switched on. On most switches, this default is VLAN 1 and should be changed for security reasons.
Which is the most common cause of slow VLAN?
A traffic loop is the most common cause of a slow VLAN. Along with a loop, you should see other symptoms that indicate that you are experiencing a loop. For troubleshooting Spanning Tree Protocol (STP) loops, refer to the document Spanning Tree Protocol Problems and Related Design Considerations.
What causes slow intervlan and intravlan connectivity?
For more information on document conventions, see the Cisco Technical Tips Conventions. The symptoms of slow connectivity on a VLAN can be caused by multiple factors on different network layers.
