LAA

Locally Administered Address is a MAC that is manually assigned by an admin. Does not need to be globally unique.

UAA

Universally Administered Address is a MAC address of a device that is assigned by the manufacturer.

OUI

Organizational Unique Identifier is the part of a MAC address that identifies the vendor of the network adapter. Usually the first 3 bytes.

Private Address Range

Which IPv6 type routes between subnets but not the internet

Unique Local

SLAAC

Stateless Address Auto Configuraiton is the preferred method of assigning IP addresses in an IPv6 network.

CAPWAP

Control and Provisioning of Wireless Access Points is a protocol that enables an access controller to manage a collection of wireless termination points.

When does a late collision occur

When a collision is detected after the 512nd bit (64th byte) of the frame

The destination MAC address of a broadcast frame

How to enter privileged executive mode on the command line

“enable” or “en”

How do you enter global configuration mode on the command line

“configure terminal” or “conf t”

How do you change the hostname of a device on the command line

“hostname {NameHere}”. You must be inside global configuration mode to achieve this

en

conf t

hostname {nameHere}

How do you enable a password on the command line

“enable pass {Password here}” or “enable password {password here}”

en

conf t

enable pass

How do you encrypt passwords on the command line

“service pass” “service password-encryption” inside of global configuration mode

How do you run a line from global configuration mode

Put a Do infront of the code

How do you show running config from the command line

“sh run” This line requires you to be inside of global configuration mode

How do you show the MAC Addresses stored in a router on the command line

Show mac address-table

Display the connected interfaces of a Router using the command line

show ip interface brief or sh ip int brief

How to show a Router’s routing table inside of

show ip route

What is a Global Unicast Address

Globally identifiable IPv6 Addresses. Equivalent to IPv4

What is a Link Local Address

IPv4 or IPv6 address is an automatically assigned address that is used before devices have been assigned an IP.

AAAA

Matches hostname to a IP Address

How to create a Vlan inside of the command line

en

conf t

int range f 0/x - y

sw mode access

sw access Vlan XX

How to configure trunking

int g 0/x

switchport trunk ? - check for encapsulation

switchport mode trunk

sw trunk allowed vlan xx,yy

sw trunk native vlan 1001 ←Any unused Vlan can go here

show vlan brief ←checks the configuration

Check the running configuration of interfaces

Show Run

LACP

Link Aggregation Control Protocol is an IEEE networking standard that combines multiple network connections or physical links in a network to form a single logical link and enable Load Balancing. If a link fails, link aggregation fail over automatically
