Important Notes

The following sections contain important notes about Cisco IOS Release 15.1S.

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 standalone document. When behavior changes are introduced, existing documentation is updated with the changes described in these sections:

Cisco IOS Release 15.1(3)S5

The following behavior changes were introduced in Cisco IOS Release 15.1(3)S5:

  • 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

  • Old Behavior: No reporting was available for Wanphy alarms.

New Behavior: Alarm reporting can be enabled for Wanphy alarms.

  • 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.

  • The warning messages indicating that support for ISG (IP or PPPoE) sessions on ES+ line cards and SIP-400 is being deprecated are displayed on configuring or unconfiguring broadband (both IP and PPPoE) on Cisco 7600.

Old behavior: No warning messages. System accepts the configuration.

New behavior: Warning message indicating that support for ISG (IP or PPPoE) sessions on ES+ line cards and SIP-400 is being deprecated. The configuration is still accepted.

76LIch2.html

Cisco IOS Release 15.1(3)S3

The following behavior changes were introduced in Cisco IOS Release 15.1(3)S3:

  • Configure “radius-server attribute 44 include-in-access-req all” instead of “radius-server attribute 44 include-in-access-req” if per vrf level attribute inclusion is not required.

Old behavior: radius-server attribute 44 include-in-access-req command applies attribute 44 for all the sessions.

New behavior: The command is modified to include the configuration of non-vrf sessions.

Additional information: http://www.cisco.com/en/US/docs/ios-xml/ios/security/m1/sec-cr-r1.html#GUID-0C067786-2A4D-4D26-A429-0E7AA331E4CD

  • 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 suninterfaces.

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

  • Change in BGP next-hop for redistributed recursive static routes.

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.

  • ASR1K BDI interface supports mtu size change.

Old Behavior: The default maximum transmission unit (MTU) size is 1500 bytes, and is not configurable.

New Behavior: For a BDI, the maximum transmission unit (MTU) size can be configured between 1500 and 9216 bytes.

Additional Information: http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/bdi.html

  • PfR syslog levels are added to minimize number of messages.

Old Behavior: There are too many PfR syslog messages.

New Behavior: PfR syslog levels are added to minimize the number of messages displayed, and a syslog notice is 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

  • A new command crypto engine hw-FIPS-mode is introduced for WS-IPSEC-3 IPsec VSPA that reloads the router if there is an FIPS test failure.

Old Behavior: If WS-IPSEC-3 IPsec VSPA fails FIPS test, it stops passing the traffic.

New behavior: A new command crypto engine hw-FIPS-mode is introduced. If you configure the crypto engine hw-FIPS-mode command on a Cisco 7600 series router and the FIPS self test fails for any of the WS-IPSEC-3 IPsec VSPA, the router reloads continuously till the router passes the FIPS self test.

Additional Information: http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76ovwvpn.html

  • New CLI command added to enable/disable BFDv6 and BFDv4 session offloading.

Old behavior: No CLI command.

New behavior: The command platform bfd disable-offload added. You can now specifically control offloading of IPv4 and IPv6 BFD sessions.

Additional Information: http://www.cisco.com/en/US/docs/ios/iproute_pi/command/reference/iri_pi1.html

Cisco IOS Release 15.1(3)S2

The following behavior changes were introduced in Cisco IOS Release 15.1(3)S2:

  • BGP scan time range is changed.

Old Behavior: The bgp scan-time command has a scanner-interval range of 15-60 seconds. The b gp 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).

  • 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, for unreachable and loss OOP cases.

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

Additional Information: See the “PfR Entrance Link Selection” section under Information About in:

http://www.cisco.com/en/US/docs/ios-xml/ios/pfr/configuration/15-2mt/pfr-bgp-inbound.html

  • Increased maximum number of traffic classes (prefixes) to be learned in a PfR learn list.

Old Behavior: Using the Cisco IOS CLI, count (PfR) command, the maximum number of traffic classes to be learned in a PfR learn list is 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: http://www.cisco.com/en/US/docs/ios-xml/ios/pfr/command/pfr-cr-book.html

  • 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:

http://www.cisco.com/en/US/docs/ios-xml/ios/oer/command/oer-cr-book.html

  • The Enhanced IPv6 Neighbor Discovery Cache Management feature was written to address these changes.

Old Behavior: Information about the enhanced IPv6 Neighbor Discovery cache management feature did not exist in documentation.

New Behavior: The “Implementing IPv6 Addressing and Basic Connectivity” has this feature.

  • Netflow and microflow configuration support

Old behavior: You cannot configure netflow and microflow policy on an interface together.

New behavior: You can configure per-interface NetFlow and QoS micro-policing on an interface. However, do not configure different flow mask types on an interface. Only a single flow mask type should be configured for per-interface NetFlow and microflow policy.

Impact on customer: Configuration of netflow and microflow policy on a interface is possible.

  • Switched Virtual Interface (SVI) based Ethernet over MPLS (EoMPLS) now works with Transport Profiles (TP).

Old Behavior: SVI based EoMPLS did not work for packets over TP.

New Behavior: SVI based EoMPLS now works for packets over TP.

Cisco IOS Release 15.1(3)S1

The following behavior changes were introduced in Cisco IOS Release 15.1(3)S1:

  • Policing options are changed for IPv6 HBH packets on SIP-400, SIP-200 and Enhanced Flexwan line cards in Cisco 7600 series routers.

Old Behavior: Setting the police rate to 0 turns off the policer.

New Behavior: Setting the police rate to 0 drops all the IPv6 HBH packets. The new test platform police ipv6 disable command turns off the policer.

  • New AAA attribute for idle timeout direction can be configured in the service profile for ISG sessions.

Old Behavior: The idle timeout direction is outbound by default.

New Behavior: The idle timeout direction can be configured in the AAA service profile; if not configured, the default is outbound.

  • Idle timeout direction for ISG IP sessions and traffic classes can be configured.

Old Behavior: The idle timeout direction for IP sessions is inbound. For traffic classes, the timer is applied in the direction of the traffic class. If the idle timer is configured in both the inbound and outbound traffic class, it is applied in the outbound direction.

New Behavior: The idle timeout direction can be configured in a service policy map using new keywords in the timeout idle command.

  • IPv6 downstream traffic from an ISG interface can be configured to pass through without a subscriber session.

Old Behavior: Downstream traffic towards a subscriber is dropped if a subscriber session is not present.

New Behavior: The passthru downstream ipv6 command allows IPv6 traffic to pass through without a subscriber session.

Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/isg/command/isg_m1.html

  • 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).

  • Policing options are changed for IPv6 HBH packets on ES+ line cards in Cisco 7600 series routers.

Old Behavior: Setting the police rate to 0 turns off the policer.

New Behavior: Setting the police rate to 0 drops all the IPv6 HBH packets. The new test platform police ipv6 disable command turns off the policer.

  • CLI is introduced to ignore S1 SONET overhead byte set to 0xF.

Old Behavior: A packet received with an S1 SONET overhead byte set to 0xF causes the router to switch the clock source to internal.

New Behavior: The atm sonet ignore s1 command has been introduced, which when set directs the router to ignore an S1 overhead byte set to 0xF, which in turn ensures that the clock does not change.

  • IPv6 downstream traffic from an ISG interface can be configured to pass through without a subscriber session.

Old Behavior: Downstream traffic towards a subscriber is dropped if a subscriber session is not present.

New Behavior: The passthru downstream ipv6 command allows IPv6 traffic to pass through without a subscriber session.

  • Server and user-agent SIP headers have only token characters.

Old Behavior: Outgoing SIP messages have nontoken characters in server and user-agent SIP headers.

New Behavior: Server and user-agent SIP headers have only token characters.
