This feature provides support for the use of the industry-standard Simple Network Management Protocol (SNMP) to monitor media streams. This support is implemented with the addition of the following Cisco proprietary SNMP Management Information Base (MIB) modules:

  • CISCO-FLOW-MONITOR-TC-MIB—Defines the textual conventions common to the following MIB modules.
  • CISCO-FLOW-MONITOR-MIB—Defines the framework that describes the flow monitors supported by a system, the flows that it has learned, and the flow metrics collected for those flows.
  • CISCO-MDI-METRICS-MIB—Defines objects that describe the quality metrics collected for media streams that comply to the Media Delivery Index (MDI) [RFC 4445].
  • CISCO-RTP-METRICS-MIB—Defines objects that describe the quality metrics collected for RTP streams, similar to those described by an RTCP Receiver Report packet [RFC 3550].
  • CISCO-IP-CBR-METRICS-MIB—Defines objects that describe the quality metrics collected for IP streams that have a Constant Bit Rate (CBR).

For detailed information about these MIBs, and to locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at http://www.cisco.com/go/mibs . This feature also includes two new command-line interface (CLI) commands and one modified CLI command. The commands are as follows:

  • snmp-server host—Enables the delivery of flow monitoring SNMP notifications to a recipient.
  • snmp-server enable traps flowmon—Enables flow monitoring SNMP notifications. By default, flow monitoring SNMP notifications are disabled.
  • snmp mib flowmon alarm history—Sets the maximum number of entries maintained by the flow monitor alarm history log.

For more information about these commands, see the Cisco IOS Master Command List.

Important Notes

The following information applies to all releases of Cisco IOS Release 15.2T.

Cisco IOS Behavior Changes

Behavior changes describe the minor modifications to the way a device works that are sometimes introduced in a new software release. These changes typically occur during the course of resolving a software defect and are therefore not significant enough to warrant the creation of a stand-alone document. When behavior changes are introduced, existing documentation is updated with the changes described in this section.

Behavior changes are provided for the following releases:

Cisco IOS Release 15.2(2)T4

The following behavior changes are introduced in Cisco IOS Release 15.2(2)T4:

  • PfR syslog levels have been added to minimize the number of messages.

Old Behavior: Too many PfR syslog messages are generated.

New Behavior: PfR syslog levels has been added to minimize the number of messages displayed and a syslog notice has been added to display when 30 percent of the traffic classes are out-of-policy.

Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/pfr/configuration/15-mt/pfr-15-mt-book.html

  • IPv6 support is added for legacy Control Plane Policing (CoPP) on Cisco Express forwarding interfaces.

Old Behavior: IPv6 support is not available for CoPP, resulting in a failure of policing and rate limiting.

New Behavior: IPv6 support is added for legacy CoPP on Cisco Express forwarding interfaces that supports aggregate-scope policing and rate limiting.

Cisco IOS Release 15.2(2)T3

The following behavior changes are introduced in Cisco IOS Release 15.2(2)T3:

  • BGP Processing of the Removal of Private AS Numbers from AS Path.

Old Behavior: When the neighbor remove-private-as command is configured and a route-map without a continue clause is configured, the processing order is:

1. neighbor remove-private-as processing.

2. set as-path prepend or set as-path prepend last-as.

However, if the route-map contains a continue clause, the processing order is reversed.

New Behavior: When the neighbor remove-private-as command is configured and a route-map is configured (whether it has a continue clause or not), the processing order is always:

1. neighbor remove-private-as processing.

2. set as-path prepend or set as-path prepend last-as.

  • RTP signal processing is disabled by default.

Old Behavior: RTP packets of payload type “123” can cause errors on Cisco AS5350 and AS5400 series platforms.

New Behavior: RTP signal processing is disabled by default to prevent errors caused by RTP packets of payload type “123,” and can be enabled when necessary using the voice-fastpath voice-rtp-signalling enable command.

Additional Information:

http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00800a96c1.shtml

  • A CLI “rtp-media-loop count” is introduced to control the maximum loop count before media packets are dropped.

Old Behavior: For IP-IP calls, there was no mechanism to limit the number of possible media loops before the media packets are dropped.

New Behavior: A CLI “rtp-media-loop count” is provisioned globally under voice service voip configuration mode to control the maximum loop count before media packets are dropped.

Addtional Information:

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/vcr3/vcr-r1.html

Cisco IOS Release 15.2(2)T2

The following behavior changes are introduced in Cisco IOS Release 15.2(2)T2:

  • The status of the snmp trap link-status command on an ATM subinterface changes when the device is reloaded.

Old Behavior: The snmp-server enable traps atm subif command enables Simple Network Management Protocol (SNMP) link trap generation on all the ATM subinterfaces. When the device is reloaded SNMP trap generation is enabled on all ATM subinterfaces.

New Behavior: To enable SNMP link trap generation on an ATM subinterface, first configure the snmp-server enable traps atm subif command in global configuration mode and then configure the snmp trap link-status command on the ATM subinterface on which SNMP link trap generation is to be enabled.

Additional Information:

http://www.cisco.com/en/US/docs/ios-xml/ios/snmp/command/nm-snmp-cr-s4.html http://www.cisco.com/en/US/docs/ios-xml/ios/snmp/command/nm-snmp-cr-s5.html

  • Connected number and Connected name are sent in an ISDN CONNECT message as Connected Number IE and Connected Name (display IE).

Old Behavior: Connected number and Connected name that are signaled to Cisco IOS software from a SIP 200 OK message are not sent in an ISDN CONNECT message.

New Behavior: Connected number and Connected name that are signaled to Cisco IOS software from a SIP 200 OK message are sent as Connected Number IE and Display IE (Connected Name) in the ISDN CONNECT message. Passing the connected number and the connected name is enabled by configuring the following commands in interface configuration mode: isdn outgoing ie connected-number , isdn outgoing ie display .

Additional Information:

http://www.cisco.com/en/US/docs/ios/dial/command/reference/dia_i2.html

  • Change to how IPv6 paths are advertised.

Old behavior: An IPv6 path is advertised without a label when the label has not been negotiated.

New behavior: IPv6 paths are not advertised if the label has not been negotiated.

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_bfd/configuration/xe-3s/irb-bfd-isis-cbit.html

  • Collected CLI set for the Call Home full inventory message are modified.

Old Behavior: The following show commands are included in the call home full inventory message: show diag , show version , show inventory oid , show environment all , show license udi , show license all , show interfaces , show file systems , show flash:all , show data-corruption , show memory statistics , show process memory , show process cpu , show process cpu history , show crypto engine configuration , show crypto engine accelerator statistics , show license detail , show license statistics , show buffers , and show ip nat statistics .
