Which Cisco Router Model required for DSCP Marking of Video Traffic 100Mb

Unanswered Question
Aug 17th, 2008

Hi All,

Please guide me which Router should be purchased for DSCP Marking (QoS) with at least 2 FE Interfaces & Traffic is Video Traffic of about 80Mbps. Also please guide if standard IP IOS will do the marking or Advanced IP IOS required ?

What about the following Router which I got from Cisco Tools.

"CISCO1811/K9 -- Security router with dual 10/100 WAN ports, 8-port 10/100BASE-T switch, V.92 analog modem backup, Cisco IOS Advanced IP Services, 32 MB Flash, and 128 MB DRAM"

Please advise.

Thanks & Regards,

Faisal

I have this problem too.

hi Faisal

this is the spesifications of the router series u have chosen

Cisco 1800 Series Integrated Services Routers

are the next evolution of the award-winning Cisco

1700 Series modular and fixed-configuration

routers. The Cisco 1801, 1802, 1803, 1811, and

1812 Integrated Services Routers are fixedconfiguration,

while the Cisco 1841 Integrated

Services Router is modular. The routers are

designed for secure broadband, Metro Ethernet,

and wireless connectivity, and provide significant

performance improvements, feature capability,

versatility, and additional value compared to prior

generations of Cisco 1700 Series. The Cisco

1800 Series fixed-configuration routers provide:

• Secure broadband access with concurrent

services for branch and small offices

• Integrated ISDN Basic Rate S/T Interface (BRI),

analog modem, or Ethernet backup port for

redundant WAN links and load balancing

• Secure wireless LAN option for simultaneous

802.11a and 802.11b/g with use of two dualmode

antennas

• Advanced security including: Stateful

Inspection Firewall, IP Security (IPSec) VPNs

(Triple Data Encryption Standard [3DES] or

Advanced Encryption Standard [AES]), Intrusion

Prevention System (IPS), Antivirus support

through Network Admission Control (NAC) and

enforcement of secure access policies

• 8-port 10/100 managed switch with 802.1q

VLAN support and optional Power over

Ethernet (PoE)

• Easy deployment and remote-management

capabilities through Web-based tools and

Cisco IOS Software

Cisco 1801, 1802, and 1803 routers provide

high-speed DSL broadband access through

asymmetric DSL (ADSL) over basic telephone

service (Cisco 1801), ADSL over ISDN (Cisco

1802), or Symmetrical High-Data-Rate DSL

(G.SHDSL) (Cisco 1803) while helping to ensure

reliable networking with integrated ISDN S/T BRI

backup. The Cisco 1811 and 1812 provide highspeed

broadband or Ethernet access through

two 10/100BASE-T Fast Ethernet WAN ports and

also provide integrated WAN backup through a

V.92 analog modem (Cisco 1811) or ISDN S/T

BRI interface (Cisco 1812

the Cisco 1800 Series fixed-configuration

routers help enable a network infrastructure

for SMBs and enterprise small branch offices,

providing access to the Internet, corporate

headquarters, or other remote offices, while

securing and protecting critical data with

integrated Cisco IOS Software security features

and capabilities. They also help businesses

reduce costs by enabling deployment of a single

device to provide multiple services (integrated

router with redundant link, LAN switch, firewall,

VPN, IPS, wireless technology, and quality of

service [QoS]) typically performed by separate

devices. Cisco IOS Software allows this

flexibility, providing the industry's most robust,

scalable, and feature-rich internetworking

support, using the accepted standard networking

software for the Internet and private WANs.

by the way if have a configurable switch such as cisco switch before the router do the marking on the switch and control the qos on the router

good luck

please, if helpful rate

Hi Marwanshawi,

Thanks for your reply. It is about detailed specifications of the Router.

I just wanted to ask, if we buy a Cisco Router these days with Standard IOS, will it do the DSCP marking or you require Advanced IOS ?

I have already go this point from Cisco Website "Support for DSCP Marking & IP Precedence Marking in Cisco IOS Software Release 12.1(5) T and later versions." BUT HOW DO U KNOW THE STANDARD IOS VERSION INSTALLED ON A NEW ROUTER. I asked this from one of Cisco Reseller & he replied that Standard IOS, check from website & I was unable to find it from Cisco website.

Secondly which series Router is required to do the DSCP Marking of about 80 Mbps Video Traffic in one class so that it will not add much delay to Traffic.

Thanks & Regards,

Faisal
