Negative:

Many networks are inadequately designed for

Management , Security and Data Segmentation

Redesign is costly and time intensive

VLAN Implementation

VLAN - Need for Separated Networks

A network has several type of traffic:

User data Traffic

Management Traffic

Control Traffic

Some customers want their User Data Traffic

separated from others users A Virtual Local Area Network (VLAN) can separate

the different traffic types

VLAN O i

8/3/2019 CPT300_v1-7

19/74

VLAN Overview

Operates at Layer 2 of the IP model

Establishes a logical group within the network

Regardless of initial or eventual physical location,each computer in the VLAN can access the samedata

Provides flexibility in network segmentation,simpler management, and enhanced security.

VLANSpecifications

Layer 2 (switch) VLAN specifications:

IEEE 802.1-Standard Based

802.1q describes the unique identifier for each VLAN 802.1p describes different priority levels within a VLAN

DiffServ (Layer 3) compatibility with L2 VLAN is possiblethrough mapping of L3-toL2 prioirity values

VLANPorts on VLAN device

Untagged Port : Attached to a non VLAN aware device.

Incoming frames are tagged with a VID. Outgoingframes are untagged

Tagged Port : Attached to a VLAN aware device.

Incoming and out-going frames have a VID A Port can belong to only ONE untagged VLAN but

may belong to MULTIPLE tagged VLANs

Filters can restrict whether tagged or untagged framesare allowed on a port

Differences in Manufactures devices Dumb VLAN switch (port based only)

Do not confirm to 802.1q Management VLAN

Layer 2 & 3 switches, ability to route VLANs

Default VLANs VLAN 1, Cannot be destroyed

Management VLAN sometimes cannot be changed from thedefault VLAN

Caution when using VLAN 1

Thorough Testing is a MUST!

Centralization

All data is backhauled to a NOC. Data is then controlled/routed as necessary.

PROs Centralized control and management

Centralized equipment

Fewer Redundant system needed

CONs Backhauls often transport a greater amount data due to

centralized routing

More powerful equipment needed at NOC

Failure effect a greater number of users

Decentralization

Equipment are placed at key locations such as towers. User datais controlled locally

PROs Less data on backhauls due to localized routing

Less powerful equipment needed at key locations

Other services can be off loaded to local devices such as DHCP, NAT,

PPPoE CONs

More complex IP address subnet structure

Greater number of devices requires higher level of management,

control and failure prevention Can result in wasted IP addresses due to increased subnet structure

Benefit, Now or Later?

APs with slightly mismatched transmit/receive ratios

and low level of data traffic may see little effect onthroughput

As the data traffic increases, the impact of mismatchedtransmit/receive ratio will increase

This means that a system that wasnt tuned forcollocation may work fine at low traffic levels, but haveissues at higher traffic level

Sometimes the bit-times will need to be closer togetherthan 300.

One customer had performance problems with a mixedcluster of hardware and software scheduled APs.

Continued using the Frame Calculator and adjustingbit-times until transmissions were within 150 bit-timesof each other.

Performance stabilized and system worked beautifully.

Making a module Advantage:

Buy it as Advantage Buy a license key for an existing P9 AP

Buy a license key for an existing P9 SM

Using BAM, buy and apply floating licenses for P9 SMs

2x only works at half the distance

Example, 5.7 GHz AP-SM, no reflectors, range is 2 miles(3.2 km). Expect 2x operations within 1 mile (1.6 km).

higher performance. Organize your network so

that P9 SubscriberModules are placed whereyou need 2X operationsAND where the module willbe able to run at 2Xoperations.

Use reflectors, if allowed,for SMs that are outsidethe half-distance but
