1
Q

VLAN

A

a logical group of end devices

2
Q

Modern design of a vlan

A

1 Vlan = 1 ip subnet

3
Q

Trunks

A

connect switches to transport multiple vlans across a single physical link (multiplexing)

4
Q

How far should a vlan at the access layer extend

A

no further than their associated distribution switch

5
Q

how do you disable trunk negotiation on a switch port

A

change the mode to access

“Switchport mode access”

6
Q

ISL Inter Switch Link

A

cisco proprietary trunking protocol

7
Q

802.1Q IEEE

A

a widely supported industry standard protocol

8
Q

native vlan

A

an untagged vlan on an 802.1q trunked switchport

9
Q

DTP Dynamic Trunking Protocol

A

a cisco proprietary protocol for dynamically negotiating trunk links

10
Q

DTP port mode Acess

A

permanent non-trunking mode

11
Q

DTP port mode Trunk

A

permanent trunking mode

12
Q

DTP port mode Nonegotiate

A

permanent trunking mode but prevents the interface from generating dtp frames used to connect devices that do not support dtp

13
Q

DTP port mode Dynamic desirable

A

the interface attempts to convert the link to a trunk link

14
Q

DTP port mode auto

A

the interface is willing to convert the link to a trunk link but nodes not negotiate it this is the default mode

15
Q

VTP Vlan Trunking Protocol

A

cisco-proprietary protocol that automates the propagation of vlan information between switches via trunk links to minimize misconfigurations

16
Q

VTP domains

A

define sets of interconnected switches sharing the same configuration

17
Q

VTP mode client

A
  • cannot create, change, or delete vlans on cmd line interface
  • forwards advertisements to other switches
  • does not save vlan configuration in NVRAM
18
Q

VTP mode Server

A
  • can create, modify and delete vlans
  • sends and forwards advertisements to other switches
  • saves vlan configuration in NVRAM
19
Q

VTP mode Transparent

A
  • Can create, modify and delete vlans only on the local switch
  • forwards vtp advertisements received from other switches in the same management domain
  • Saves vlan configuration in NVRAM
20
Q

VTP Operation

A
  • VTP advertisements are sent as multicast frames
  • VTP servers and clients are synchronized to the latest revision number
  • VTP advertisements are sent every 5 mins or when something is changed
21
Q

VTP Pruning

A

prevents flooded traffic from propagating to switches that do not have members in specific vlans

22
Q

VTP Versions 1

A

V1 transparent switches inspect vtp messages fro the domain name and version and forward a message only if the version and domain name match

23
Q

VTP Versions 2

A

V2 transparent switches forward VTP messages in transparent mode without checking versions

24
Q

VTP Versions 3

A

V3 adds pramry and secondary server roles

  • extended vlan range support 1025-4094
  • supports private vlans
25
Q

VTP Message Type Summary Advertisements

A

inform adjacent switches of the current vtp domain name and the configuration revision number

26
Q

VTP Message Type Subset Advertisements

A

contains a list of vlan information

27
Q

VTP Message Type Requests

A

this happens when a switch is reset
the vtp domain name has been changed
the switch has received a vtp summary advertisement with a higher configuration revision than its own

28
Q

EtherChannel Technology

A

upto 8 physical links can be bundled into a single logical ether channel link

29
Q

EtherChannel Management Protocols PAgP (Port Aggregation Protocol)

A

a cisco proprietary protocol that aids in the automatic creation of the fast etherchannel links

30
Q

EtherChannel Management Protocols LACP ( Link Aggregation Control Protocol)

A

is part of an IEEE specification that also allows several physical ports to be bundled together to form an etherchannel
- better descriptive names for modes
