1. Catalyst switch VLAN configuration info is stored with a VLAN database file. Located in the flash memory of a switch. 
  2. Technology developed by Intel and licensed to other semiconductor companies. Allows software images to be stored, booted, and rewritten as necessary
  3. A Cisco-proprietary Layer 2 protocol that enables a network manager to configure a single switch so that it propagates VLAN configuration info to other switches in the network, as well as synchronizes the info with the switches in the VTP domain.
    VLAN Trunking Protocol (VTP)
  4. A VLAN that is configured to carry only user-generated traffic. Does not carry voice-based traffic or traffic used to manage a switch
    Data VLAN
  5. The VLAN that all the ports are on a switch are members of when a switch is reset to factory defaults. All switch ports are members of the VLAN after the initial boot of the switch
    Default VLAN
  6. A dummy VLAN distinct from all other VLANs. All unused ports are assigned to this VLAN so that any device connecting to an unused switch port will be assigned to this VLAN. Any traffic associated with this VLAN is not allowed on trunk links, thus preventing any device associated with this VLAN from communicating beyond the switch to which it is connected.
    Black Hole VLAN
  7. A project in the IEEE 802 standards process to develop a mechanism to allow multiple bridged networks to transparently share the same physical network link without leaking info between networks. Also the name of the encapsulation protocol used to implement this mechanism over Ethernet networks.
    IEEE 802.1Q
  8. A means of accessing the management capabilities of a switch
    Management VLAN
  9. Designed for and dedicated to the transmission of voice traffic involving Cisco IP phones or Cisco Softphones
    Voice VLAN
  10. IP telephony traffic responsible for call setup, progress, and teardown, traversing the network end-to-end.
    Signaling Traffic
  11. One in which ports on the switch are manually assigned
    Static VLAN
  12. A Layer 3 logical interface associated with a specific VLAN
    Switch Virtual Interface (SVI)
  13. An Ethernet point-to-point link between an Ethernet switch interface and an Ethernet interface on another networking device, such as a router or a switch, carrying the traffic of multiple VLANs over the singular link. Allows you to extend the VLANs across an entire switched LAN
    VLAN Trunk
  14. A standard that provides traffic class expediting. It provides a mechanism for implementing QoS at the MAC sublayer
    IEEE 802.1p
  15. A single bit flag value in the IEEE 802.1Q header. Indicates that all MAC address info present in the MAC address data
    Canonical Format Identifier (CFI)
  16. The parameter in the IEEE 802.1Q tag that indicates the VLAN the frame is associated with.
  17. A normal Ethernet frame in a switched LAN
    Untagged Frame
  18. A Cisco-proprietary protocol that maintains VLAN info as traffic flows between switches and routers, or switches and switches. Used by trunk ports to encapsulate Ethernet frames between network devices.
    Inter-Switch Link (ISL)
  19. A Cisco-proprietary protocol that negotiates both the status and encapsulation of trunk ports.
    Dynamic Trunking Protocol (DTP)
  20. Used by DTP to negotiate the status of a trunk port.
    Trunking Mode
  21. The trunking option that sets the local port to be in an unconditional trunking state with DTP disabled. Use this feature when you need to configure a trunk with a switch from another switch vendor.
  22. A DTP setting whereby the local switch port advertises to the remote switch port it is able to trunk but does not request to go to the trunking state.
    Dynamic Auto
  23. A DTP setting whereby the local switch port advertises to the remote switch port that it is able to trunk and ask the remote switch port to go to the trunking state
    Dynamic Desirable
  24. Each VLAN trunk supports a set of allowed VLANs. Data associated with these VLANs is transmitted over the respective trunk link; remaining data is not transmitted over the link.
    Allowed VLAN
  25. A Cisco-proprietary Layer 2 protocol that enables a network manager to configure a single switch so that it propagates VLAN configuration info to other switches in the network, as well as synchronizes the info with the switches in this domain
    VLAN Trunking Protocol (VTP)
  26. A set of Catalyst switches with the same VTP domain name; all switches share the same synchronized VTP info
    VTP Domain
  27. Messages transmitted between Catalyst switches to share and synchronize VLAN configuration details in the switched LAN
    VTP Advertisements
  28. VTP has three operating modes: server, client, and transparent. The operating mode determines how the switch uses and shares VLAN info within the VTP domain
    VTP Modes
  29. advertise the VTP domain VLAN info to other VTP-enabled switches in the same VTP domain. store the VLAN info for the entire domain in NVRAM. where VLANs can be created, deleted, or renamed for the domain. It may take multiple subset advertisements to fully update the VLAN info. 
    VTP Server
  30. participate in VTP operation, but do not permit creating, changing, or deleting of VLANs on the client itself. A VTP domain only while the switch is powered on. A switch reset deletes the VLAN info. A switch must be manually configured to change its mode 
    VTP Client
  31.  forward VTP advertisements to VTP clients and VTP servers, but does not originate or otherwise process VTP advertisements. VLANs that are created, renamed, or deleted on a on this switch are local to that switch only. 
    VTP Transparent
  32. Prevents unnecessary transmission of VLAN info from one VLAN across all trunks in a VTP domain. permits switches to negotiate which VLANs have active associations with ports on the portion of the network connected to the opposing end of a trunk link and, hence, prune the VLANs that are not actively associated with ports on that portion of the network. disabled by default.
    VTP Pruning
  33. VTP has three versions: version 1, version 2, and version 3
    VTP Version
  34. A number that indicates the current state of the VLAN info on the switch. The number enables the synchronization of VLAN info within the VTP domain
    VTP Configuration Revision Number
  35. an algorithm used for massage authentication in SNMPv2 and several other network protocols. verifies the integrity of the communication, authenticates the origin, and checks for timeliness.
    Message Digest 5 (MD5)
  36. must match on all switches in a VTP domain. secures the info in the VTP domain and prevents a rogue switch added to a network from compromising VLAN info.
