  • IEEE 802. 1Q – VLAN Tagging and Trunking in Networking
    VLAN tagging is the process of inserting VLAN-related information into Ethernet frames This helps network devices identify which VLAN a frame belongs to when traversing trunk links VLAN tagging is primarily used to distinguish traffic in environments where multiple VLANs share the same physical infrastructure
  • vlan 0, 1, and 4095 are reserved: what are they reserved for?
    VLAN identifier (VID): a 12-bit field specifying the VLAN to which the frame belongs The hexadecimal values of 0x000 and 0xFFF are reserved All other values may be used as VLAN identifiers, allowing up to 4,094 VLANs
  • Best Practices for Inter-VLAN Routing in CISCO - Cisco Learning Network
    In this method, each VLAN has a dedicated physical port on the router This setup is simple but requires more physical interfaces Best Practices: Suitable for small networks with few VLANs Assign different subnets to each VLAN for easy management Use firewall rules to enhance security between VLANs Security Tips for Inter-VLAN Routing
  • Different types VLAN - Cisco Learning Network
    Default VLAN (VLAN 1): All switch ports belong to VLAN 1 by default Data VLAN: Segregates user traffic based on logical groupings Voice VLAN: Carries voice traffic for VoIP phones Management VLAN: Used for managing the switch itself some time also for SNMP and other management Native VLAN: Assigned to untagged traffic on trunk ports
  • If Native VLAN is Not Used Then . . . . - Cisco Learning Network
    I'd really like to know how the Native VLAN is handled in real-world networks To prevent VLAN-Hopping and other security problems, can I just create a VLAN, let's call it VLAN 11 (name Native_VLAN) and specify VLAN 11 in switchport trunk native vlan 111 commands on all trunks?
  • Why and how are Ethernet Vlans tagged?
    To do this you are "tagging" a packet with a VLAN tag (or VLAN header if you like) In reality a VLAN tag is inserted in the Ethernet frame like this: The 802 1Q (dot1q, VLAN) tag contains a VLAN-ID and other things explained in the 802 1Q Standard The first 16 bits contain the "Tag Protocol Identifier" (TPID) which is 8100
  • What are the differences between Native Vlan vs Default Vlan vs Vlan 1?
    The default VLAN is always set to VLAN 1 and it is the VLAN that comes pre-configured on every switch (Cisco, HP, etc) The concept behind this is that the switch needs at least one VLAN to operate as a switch hence the reason for VLAN 1
  • Cisco Learning Network
    Default Description OneTrust LLC (OneTrust) is a provider of privacy management software platform The company's platform supports organizations to adhere compliance with the data privacy, governance and security regulations across sectors and jurisdictions
  • VLAN range 1006-1024 - Cisco Learning Network
    The VLAN range 1006-1024 is reserved for internal VLANs If a vlan allocation policy is ascending, right? and if you are using Catalyst switches, they are not supported Well, I could configure it on such old and real gears as C3550 and C3560 Oddly enough, VLAN range '1006-1024' is support even in those old switches, not to mention new models
  • Understanding VLAN tagging and untagging of ports
    If a VLAN is tagged on a port, it means that data from that VLAN is sent out the port in 802 1q format, which has a VID (a tag) that identifies what VLAN it's associated with Also, data received with a VLAN tag is placed in the appropriate VLAN If the VLAN is untagged, it is sent in "standard" 802 3 Ethernet, with no VLAN information
