Cisco 2800 tunnel bandwidth limiting

Hi there,

I'm new to the forum and to Cisco having spent most of my working life in Nortel land. I am looking for advice as to how to limit bandwidth for the following tunnel config -

!

bridge irb

!

!

!

interface Tunnel1

ip unnumbered Loopback0

ip route-cache flow

keepalive 5 4

tunnel source Loopback0

tunnel destination 192.168.253.2

bridge-group 1

!

interface Loopback0

ip address 192.168.254.2 255.255.255.255

ip route-cache flow

!

interface FastEthernet0/0

description Public ADSL line

no ip address

ip route-cache flow

duplex full

speed 100

bridge-group 1

!

interface FastEthernet0/1

no ip address

shutdown

duplex auto

speed auto

!

The tunnel is currently carrying internet traffic going across Vsat with no limitation but we are about to move it to a fibre link and the internet circuit we are going to use is much larger than the current setup and so we will need to limit the bandwidth.

Any advice greatly appreciated.

Will a simple bandwidth statement in that config do the job ie 'bandwidth 1024' ?

No it won't.  The bandwidth statement just sets a logical value, although other "things" can use it.

Normally you limit bandwidth by policing on an ingress interface, might be physical or logical (tunnel).

For egress interfaces, you can police too, or perhaps shape.

Since you're bridging, unsure policers/shapers would work as they do on routed ports.

Thanks for replying Joesph. So think because we are bridging it may not be possible to police / shape the traffic on this tunnel? So I should perhaps look at a different means of keeping this traffic isolated and shaped across our link?

Again, not sure, when using bridging.

Quickest way to check might be to simply place a service policy on bridged tunnel or physical interface and see if it works as desired.

Are you familiar with using in/out service policies?
