Easy Traffic Shaping in Cisco IOS<\/h1>\n
You can enable shaping on an interface (or sub-interface) in three easy steps. Just remember: class, policy, interface.<\/div>\n

<\/p>\n

Class<\/div>\n
\n
\n

TERMINAL<\/p>\n

    \n
  • class-map match-any CLASS_SLAP <\/li>\n
  • match any <\/li>\n<\/ul>\n<\/div>\n<\/div>\n
    On the router, we have the ability to tell the class map to match any traffic. This is in contrast to the Catalyst switch where we had to specify an access-list to match on. This saves us a step and achieves the exact same results. In this case, we are going to assign all traffic to the CLASS_SLAP<\/code> class.<\/div>\n

    <\/p>\n

    Policy<\/div>\n
    \n
    \n

    TERMINAL<\/p>\n

      \n
    • policy-map POLICY_SLAP<\/li>\n
    • class CLASS_SLAP<\/li>\n
    • shape average 8000000<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
      Now it’s time to define our policy map. In this case, we’re going to take any traffic that matched the CLASS_SLAP<\/code> class (which, as you remember, is all<\/strong> traffic) and apply a shaping policy to it. We use the shape average 8000000<\/code> configuration command to limit our speed (the CIR<\/acronym>) to 8 Mbps. Another configuration command available for a policy map is bandwidth<\/code>, which has a similar effect. Unfortunately, a policy map utilizing the bandwidth<\/code> configuration command can not be applied to a sub-interface. This limitation may not be a problem for you, though.<\/div>\n

      <\/p>\n

      Interface<\/div>\n
      \n
      \n

      TERMINAL<\/p>\n

        \n
      • interface GigabitEthernet0\/3.429<\/li>\n
      • encapsulation dot1Q 429<\/li>\n
      • service-policy output POLICY_SLAP<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
        Finally, we need to apply the policy map to an interface using the service-policy<\/code> configuration command. In this example, I used a sub-interface to make the example a little more applicable to real word circumstances. I’ve also applied the policy map in the outbound direction. Thus, the users of VLAN<\/acronym> 429 are only allowed to download at an aggregate of 8 Mbps.<\/div>\n
        Wasn’t that easy? How do your own experiences compare?<\/div>\n","protected":false},"excerpt":{"rendered":"
