The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

To locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use the Cisco MIB Locator found at the following URL:
http://tools.cisco.com/ITDIT/MIBS/servlet/index
If the Cisco MIB Locator does not support the MIB information that you need, you can obtain a list of supported MIBs and download MIBs from the Cisco MIBs page at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
To access the Cisco MIB Locator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:
The following sections contain important notes about Cisco IOS Release 15.3S:
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.
The following behavior changes were introduced in Cisco IOS Release 15.3(1)S2:
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.
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
The following behavior changes were introduced in Cisco IOS Release 15.3(1)S1:
Old Behavior: The deprecation message for the enable secret 5 password command displayed the md5 encrypted secret key in the warning.
New Behavior: The md5 encrypted secret key in the deprecation message for the enable secret 5 command was removed and the following warning message was added.
Warning: The CLI will be deprecated soon
Please move to enable secret CLI

#GUID-944C261C-7D4A-49E1-AA8F-C754750BDE47
Old Behavior: If the BGP Enhanced Attribute Error Handling feature is enabled, BGP places the MP_REACH attribute (attribute 14) at the beginning of the attributes list while formatting an update. If the feature is not enabled, BGP places the MP_REACH attribute at the end of the attributes list, which makes handling a malformed update more difficult for neighbor routers that are doing enhanced error handling.
New Behavior: Whether or not the BGP Enhanced Attribute Error Handling feature is enabled, BGP places the MP_REACH attribute (attribute 14) at the beginning of the attributes list while formatting an update. Enhanced error handling can function much more easily when the MP_REACH attribute is at the beginning of the attributes list.
Old Behavior: When configuring the editor-type editor command, the router would copy the default profile to default editor if the default editor was not modified.
New Behavior: The editor-type editor command only changes the editor-type but never copies default profiles to default editors.
If user wants to reuse previous profile configurations, he can use the test sbc profile-to-editor sip, which helps to generate editor configurations from the profile.
Old Behavior: No reporting was available for Wanphy alarms.
http://www.cisco.com/en/US/docs/routers/7600/install_config/ES40_config_guide/es40_chap10.
html#wp1468974
Old Behavior: The interworking vlan command does not work, which causes traffic failure.
New Behavior: The interworking vlan command is now working. However, you must enter the clear mpls ldp neighbor * command before using the interworking vlan command the first time.
Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/mp_l2_vpns/configuration/15-s/
mp-l2vpn-intrntwkg.html
Old Behavior: SIP calls with TCP control depleted stub control buffer.
New Behavior: The sck-pool-size command was added to configure the SIP socket control buffer size.
New Behavior: Automatic recovery can be configured to bring the EVC status up if the EVC goes to error-disabled state.
Impact to customer: Use the errdisable recovery cause l2proto-tunnel time command to configure the automatic recovery timer to bring the EVC service instance status to up once the timer expires.
Additional Information: http://www.cisco.com/en/US/docs/routers/7600/ios/15S/configuration/guide/l2pt.html#wp1004668
Old Behavior: In the Cisco IOS XE Release 3.8S, the iWAG may fail to establish the GTPv1 tunnel with the GGSN, for example, with ASR 5000 platform. To address this issue, a workaround of prepending 19 to the original MSISDN number was introduced in the Cisco IOS XE Release 3.8S. This workaround changes the subscriber profiles.
New Behavior: This issue is fixed in the Cisco IOS XE Release 3.8.1S. Therefore for new customers, this workaround is not required. For customers who are using the workaround provided in the Cisco IOS XE Release 3.8S, the following commands are added in the Cisco IOS XE Release 3.8.1S to provide flexibility on MSISDN encoding:
information-element msisdn [ npi npi-value | ton ton-value]
radius msisdn leading-digits number of digits

html#wp1092140
Limitations: Pause frames that use 0180C2000001 cannot be L2PT forwarded or dropped because they are consumed by the forwarding ASIC's physical registers without sending them to the CPU.
Dot1x that uses 0180c2000003 is disabled by the Cisco ME 3800 and ME 3600 switches. This functionality is the same as in previous releases.
L2PT tunneling for the reserved MACs is not supported since the reserved MACs do not have known link types. Reserved MACs tunneled with 0180C200000B are replaced to ensure packets egress.
The LinkOAM, ELMI, and ESMC protocols are considered to be “L2PT peer” even if the L2PT CLI is not applied on the interface. Unlike other protocols, L2PT code assumes it to be drop. This is done to avoid L2PT peer configuration for LinkOAM, ELMI, and ESMC since these protocols previously worked without L2PT configurations.
Old Behavior: No recovery action is taken when the diagnostic tests TestFabricCh0Health and TestFabricCh1Health fails continuously.
New Behavior: A recovery action is introduced for every two consecutive failure of the diagnostic tests TestFabricCh0Health and TestFabricCh1Health.
