VLAN: Details, Details, Details

VLAN Database Mode

Enter at enable prompt, not global configuration mode.

You must use the word ‘apply’ or ‘exit’ to have changes saved, otherwise VLANs will not show in database.

VLAN Design Rules

Keep core switches available purely for switching

VLAN scheme should keep broadcasts and multicasts away from core

End to end VLAN 80/20 rule 80 percent of the local traffic stays within the local area and the other 20 will traverse the network.

Local VLANs 20/80 – 20 local in scope and 80 percent to traverse network

Users are grouped by location with local VLAN design
