Temperature and Voltage Monitoring

The Cisco Connected Grid Router 2010 includes sensors that measure the status and internal temperature of critical components. Internal component temperatures are measured for the central processor, internal components, and interface cards. By default, a 72-hour temperature history is stored for the central processor at one-hour intervals.

Power consumption and power supplies are monitored. The measured temperature is compared to predetermined threshold limits and, if the temperature does not fall within the limits, the information is recorded and a warning sent to the system administrator by means of Simple Network Management Protocol (SNMP) traps until the temperature falls back to its normal range.

You can store historical temperature and power supply voltage data. New show commands have been added to allow you to check the temperature and power supply voltage history configuration and data. For additional details, see the Cisco Connected Grid Router 2010 Software Configuration Guide at the following URL:

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(1)T2

Cisco IOS Release 15.2(1)T4

The following behavior changes are introduced in Cisco IOS Release 15.2(1)T4:

  • 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

  • Initial INVITE with 0.0.0.0 call flow is supported.

Old Behavior: Initial INVITE with 0.0.0.0 is not supported unless ACK contains valid ip address.

New Behavior: This call flow is supported.

Additional Information:

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/sip/configuration/15-mt/voi-sip-rfc.html#GUID-B6E5879A-D5DC-4E2C-BC97-AC927985E10E

  • 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 support aggregate-scope policing and rate limiting.

Cisco IOS Release 15.2(1)T3

The following behavior changes are introduced in Cisco IOS Release 15.2(1)T3:

  • 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 have 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/15-1mt/pfr-15-1mt-book.html

  • Fast Network Time Protocol (NTP) synchronization is achieved.

Old Behavior: The burst and initial burst (iburst) modes are enabled manually.

New Behavior: The burst and iburst modes are enabled by default.

Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/bsm/command/bsm-cr-n1.html#GUID-CC69EFC5-68A3-4C5D-90CD-67DE45D4A370

  • The telecom-solutions keyword is not supported.

Old Behavior: The telecom-solutions keyword in the ntp refclock command allows users to configure the reference clock driver.

New Behavior: Effective with CSCtu20233, the telecom-solutions keyword, along with its options, is visible but cannot be configured.

Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/bsm/command/bsm-cr-n1.html#GUID-875B8F64-2179-4F71-8BC0-6BF103EBB22F

Cisco IOS Release 15.2(1)T2

The following behavior changes are introduced in Cisco IOS Release 15.2(1)T2:

• Output from the show policy-map command does not display the default burst rate; however, the output does display the user-specified burst rate.

Old Behavior: Output from the show policy-map command displays the default burst rate.

New Behavior: Output from the show policy-ma p command does not display the default burst rate. The output does display the burst rate specified by the police command in a policy map.

• BGP scan time range is changed.

Old Behavior: The bgp scan-time command has a scanner-interval range of 15-60 seconds. The bgp scan-time command cannot be configured (it remains at the default value of 60 seconds) if BGP Next Hop Tracking (NHT) is configured (by the bgp nexthop command).

New Behavior: The bgp scan-time command has a scanner-interval range of 5-60 seconds. The bgp scan-time command can be configured, even if BGP Next Hop Tracking (NHT) is configured (by the bgp nexthop command).

• CSCtu80224

BGP next-hop for redistributed recursive static routes is changed.

Old Behavior: A router advertising a locally originated route (from a static route with recursive next-hop) advertises the next hop to be itself. The local next-hop (equal to next-hop-self) is kept.

New Behavior: A router advertising a locally originated route (from a static route with recursive next-hop) advertises the next-hop to be the recursive next-hop of the static route.

• Maximum number of traffic classes (prefixes) to be learned in a PfR learn list is increased.

Old Behavior: Using the Cisco IOS CLI, count (PfR) command, the maximum number of traffic classes to be learned in a PfR learn list was 100, with a default of 50.

New Behavior: Using the Cisco IOS CLI, count (PfR) command, the maximum number of traffic classes to be learned in a PfR learn list is 1000, with a default of 1000.

Additional Information: The command is documented in the Performance Routing Command Reference at: http://www.cisco.com/en/US/docs/ios-xml/ios/pfr/command/pfr-cr-book.html

• Increase in autonomous system number or community prepending in BGP Inbound Optimization using PfR.

Old Behavior: In both the “BGP Autonomous System Number Prepend” and “BGP Autonomous System Number Community Prepend” methods of controlling inside prefixes using PfR, the number is increased one by one up to the maximum of six ASes in unreachable, loss, and delay OOP cases.

New Behavior: In both the “BGP Autonomous System Number Prepend” and “BGP Autonomous System Number Community Prepend” methods of controlling inside prefixes using PfR, the new behavior increases the AS number or community to the maximum of six immediately, or it decreases to zero in unreachable and loss OOP cases.

In the delay OOP case, the behavior is the same as the old behavior.

• Documentation changes to support the hiding of the Optimized Edge Routing (OER) CLI.

Old Behavior: OER border router functionality is supported on the Catalyst 6500 switch.

New Behavior: OER is no longer supported on the Catalyst 6500 switch, and the OER CLI is hidden.

Additional Information: See the Cisco IOS Optimized Edge Routing Command Reference :

  • Multiple Crypto Engines.

Old Behavior: When a powerful crypto engine starts, it disables the less powerful crypto engine and handles all IPv4 and IPv6 crypto functions.

New Behavior: If there are multiple crypto engines in a network that has IPv4 and IPv6 traffic, one crypto engine handles IPv4 traffic and another crypto engine handles IPv6 traffic. It is also possible that one crypto engine handles both IPv4 and IPv6 traffic.
