Use class-based policing to assign packets to a QoS group. The router uses the QoS group to determine how to prioritize packets.

Traffic can be marked without using the Class-Based Policing feature. Class-based policing can be configured on an interface or a subinterface, but it is not supported on EtherChannel or tunnel interfaces.

Hierarchical policing policing at both parent level and child level is not supported. Specifies the name of the class map to be created and enters QoS class map configuration mode. The class map defines the criteria to use to differentiate the traffic. For example, you can use the class map to differentiate voice traffic from data traffic, based on a series of match criteria defined using the match command. If the match-all or match-any keyword is not specified, traffic must match all the match criteria to be classified as part of the traffic class.

You can enter up to four matching criteria, as number abbreviation 0 to 7 or criteria names critical, flash, and so on , in a single match statement. Creates or modifies a policy map that can be attached to one or more interfaces to specify a service policy, and enters QoS policy-map configuration mode.

Specifies the name of the class whose policy you want to create or change or specifies the default class commonly known as the class-default class before you configure its policy, and enters policy-map class configuration mode. Enter either the input or output keyword and the policy map name. Use the show policy-map interface command to verify that the Class-Based Policing feature is configured on your interface. If the feature is configured on your interface, the show policy-map interface command output displays policing statistics.

Check the interface type. Verify that class-based policing is supported on your interface. In the following example, class-based policing is configured with the average rate at bits per second, the normal burst size at bytes, and the excess burst size at bytes for all packets leaving the interface.

The series of packets are policed based on the following rules:. If the previous arrival of the packet was at T1 and the current arrival of the packet is at T, the bucket is updated with T - T1 worth of bits based on the token arrival rate.

The refill tokens are placed in the conform bucket. If the tokens overflow the conform bucket, the overflow tokens are placed in the exceed bucket. The token arrival rate is calculated as follows:. If the number of bytes in the conform bucket is greater than the length of the packet for example, B , then the packet conforms and B bytes should be removed from the bucket.

If the packet conforms, B bytes are removed from the conform bucket and the conform action is taken. The exceed bucket is unaffected in this scenario.

To configure the feature, use the platform hardware throughput command, as shown in the following example: Example Router config platform hardware throughput level? Router config platform hardware throughput level Smart Licensing is the next generation licensing platform for all Cisco software products. Domain-Based Whitelisting for Cloud Web Security—Domain-based whitelisting allows you to bypass some of the web traffic directly to web-server and helps you to skip the Cisco Web Security scanning.

Cisco IOS software provides a wide array of voice features on gateway routers. Note : Multicast connection trunk is not included in this release.

The command debug vpm sig to monitor the connection trunk signaling is not applicable in Cisco series platform as these signaling packets are no longer sent to IOSd in Cisco series ISR.

They are handled in data plane by DSP. SIP and H. For more information on SIP and H. This feature provides a cost-effective way to increase the bandwidth for particular applications by enabling multiple serial links to be aggregated into a single bundle of bandwidth. For more information, see the Frame Relay - Multilink chapter. You can configure the media for failover redundancy when the network goes down.

When you receive a second call, you hear a call-waiting tone a tone with a ms duration. Caller ID appears on phones that support caller ID. Call Transfers— Call transfers are when active calls are put on hold while a second call is established between two users.

After you establish the second call and terminate the active call, the call on hold will hear a ringback. The Call Transfer feature supports all three types of call transfers—blind, semi-attended, and attended. Music streams from an MOH server to the voice interfaces of on-net and off-net callers that have been placed on hold. Cisco Communications Manager supports the capability to place callers on hold with music supplied from a streaming multicast MOH server. Media can be configured for failover redundancy when the network goes down.

Before You Begin. Workaround: Apply the following view to exclude cEigrpInterfaceEntry from being polled: — snmp-server view cutdown iso included — snmp-server view cutdown 1. Workaround: Avoid flapping crypto session under stress traffic.

Conditions: This problem occurs when you install any serial card and Service-Engine card, then run the show interface description command.

Conditions: This problem occurs with the analog traffic and forward configuration. Conditions: This problem occurs when the Cisco ISRX series device interprets an internal packet as an Ethernet packet and drops the packet. Conditions: This happens when there are multiple tunnel interfaces and all the traffic is tunneled to the same physical interfaces, with multiple routes for each tunnel traffic, where route distance determines the physical interface for the tunnel traffic.

Conditions: This problem occurs when Cisco ISRX series device interprets an internal packet as an Ethernet packet and drops the packet. The module software may require an update?

Conditions: When you add a modem to the auxiliary port of a Cisco ISR X and then configuring it, the router reloads. Conditions: 1 Create port-channel and enable EVC. Workaround: Remove the EVC configuration explicitly from the port-channel and then, remove the physical interface from the port-channel.

Conditions: The cable is disconnected or the peer connection is shutdown. CSCuj Symptom: On the router, certain special characters sent to the module console session can result in a locked session which will no longer accept input.
