Hi

How to restrict GRE Tunnel with a maximum of 4MB transmit and receive.

thanks

Using QoS, Just an illustration. the command syntax might not exactly match.

1. define ACL for GRE traffic

access-list 100 permit gre host IP1 host IP2

access-list 101 permit gre host IP2 host IP1

2. define the class-map

class-map GRE-OUTGOING

match access-group 100

class-map GRE-INCOMING

match access-group 101

3. define policy-map

policy-map out

class GRE-OUTGOING

  bandwidth xxxxx

policy-map in

class GRE-INCOMING

  bandwidth xxxxx

4. applicy the policy-map to the interface in both iincomg and outgoing directly.

refer to the "Modular Quality of Service Command-Line Interface" configuration guide for the detail

Thanks Wu

Network Management Server requires to configure Bandwidth on the physcial and Tunnel interfaces. On applying the bandwidth command still no luck.

Am I missing anything, Router model is 3845, ios is 12.4

Internet Bandwidth  - 5MB

LAN connection - 100MB

tunnel interface I need to configure as 2MB

Config for Bandwith command looks  like -

Interface Tunnel 10

Bandwidth 2000

interface fa 0/0

description "LAN"

bandwidth 10000

interface fa 0/1

Description "ISP"

bandwidth 5000

Not sure why you mention this bandwidth command.

Bandwidth command under the interface does not restrict the rate of tx/rx. It is just used for the calculation purpose such as routing protocol's metric.

The bandwidth command under the policy-map will do the trick.
