How to implement bandwidth distribution in 1841 router

hello cisco enthusiast.

I would like to ask help from you how would this configuration goes.

I got a 5MBps Lease Line Connection via FAST ETHERNET PORT. i got a Cisco 1841 Router.

I want to distribute bandwidth in this ratio 2MBps/2MBps/1MBps

2MBps = Office Connection

2MBps = Computer Laboratory Connection

1MBps = WIFI Connection

1841 has only 2 Fast Ethernet ports

so im planning to add up a 2modules of 2-Port Fast Ethernet High-Speed WIC for Cisco Integrated Services Routers

thank you

For leased line, if your router supports CBWFQ, you can setup classes for your 3 groups.  This would work well for outbound traffic, but inbound (unless you manage the far side's egress) is very, very difficult to effectively manage.

policy-map egressSample

class office

bandwidth percent 20

class lab

bandwidth percent 20

class wifi

bandwidth percent 10

You'll need class-maps to match traffic.

just confirmed the ISP Providers side they will be deploying the Lease Line via FE.

i was lookinf for a guide how would i apply the following policy map into each port. simulation done on packet tracert.

can you assist me further?

Unknown exactly what your simulator will support, i.e. what I might suggest might not be accepted on it.  Also, even with real routers, features can vary, i.e. also again what I might suggest might not be accepted on your actual router.  Lastly, I'm not at a real router, at the moment, to verify syntax.  All that noted, something like:

ip access-list extended OFFICE

permit ip 192.168.0.1 0.0.0.255 any

class-map match-all OFFICE

match access-group OFFICE

(similar for other networks)

interface serial0/1/0 (or whatever interface you'll be using to isp)

service-policy output EGRESS

PS:

If hand-off will be FE, you'll like want a hierarchal policy.

e.g.

policy-map EGRESS_SHAPE

class class-default

service-policy EGRESS

shape average 5000000

(apply this policy to interface instead)

Re: How to implement bandwidth distribution in 1841 router

I'm aware that simulator vary on actual device especially with the IOS installed on it.

but with this. it will help me with the goal i want to attain. if i could make this work. all left with me to do access-list blocking like p2p and other bandwidth hog protocols.

the main concern is with the outbound traffic going to different locations.

will give feedback anytime once i got this working with a simulator. GNS3 would be a better option.

thank you for now.

If your targeted IOS support HQF, I would also suggest adding fair-queue to each class queue.

If your IOS is pre-HQF, you policy might not be accepted with your bandwidth settings since the total beyond 75% (excluding default).  Either using smaller percentages (as I did earlier - ratios will still be preserved) or you'll need to change reserved bandwidth on interface.

Re: How to implement bandwidth distribution in 1841 router

for 1841 router. what IOS should be installed to support all your suggestions? im not familiar with IOS capability all i know enterprise has it all.

Assuming its supported for the 1841, recall HQF is 12.4(20)T or later; any feature set.

Hello Joseph,

current version of the 1841 router im using is

Cisco IOS Software, 1841 Software (C1841-IPBASE-M), Version 12.4(17b)

Try:

class-map match-all OFFICE

match access-group name OFFICE

You should be able to apply policy to your serial.

Unless you have a really need to restrict outbound usage per class, remove the child class shapers.  The CBWFQ policy will insure each class gets its minimum proportion of bandwidth, but they can use more if its available (i.e. not being used by your other classes).

PS:

Since your simulator is pre-HQF, I would just shape for your aggregate.  This will enable WFQ for all flows.

i was missing a syntax.

All need to restrict is Download bandwidth from WAN to LAN(either OFFICE/LAB/WIFI), while Upload bandwidth will be maximized by OFFICE only(if possible to config this)

will i remove the shaping from the config?

how would i "shape for aggregate?"

Download is difficult to correctly restrict.  For upload, you need the shaper if working with less than full interface bandwidth.

how would i "shape for aggregate?"

It should, although I suggest this as better:

  bandwidth percent 20

class LABORATORY

  bandwidth percent 20

class WIFI

  bandwidth percent 10

policy-map EGRESS_SHAPE

class class-default

  shape average 5000000

  service-policy EGRESS

How to implement bandwidth distribution in 1841 router

You want CBWFQ for outbound traffic (shaping) and policing for inbound traffic.  Policing is described in further detail:
