The Multicast Address Group Range Support feature enhances multicast access control by introducing the capability to define a global range of multicast groups and channels to be permitted or denied using the ip multicast group-range command.
Multicast MIB VRF Support
The Multicast MIB VRF Support feature is an enhancement to help manage Cisco devices in a multicast VPN (MVPN) environment using SNMP. This feature enhances the Cisco suite of supported multicast MIBs by making the following multicast MIBs VRF aware:
•
•
•
•
•
•
Multicast VRF (MVRF) awareness enables the MIB objects associated with these multicast MIBs to be queried and set for the individual MVRFs configured. In addition, MVRF awareness provides the capability to detect conditions for a trap inside of an MVRF and look up the correct information for that MVRF; the traps would then be sent to the SNMP manager that is configured for that MVRF.
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.

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 this section.
Behavior changes are provided for the following releases:
Cisco IOS Release 15.0(1)M9
The following behavior changes are introduced in Cisco IOS Release 15.0(1)M9:
•
Old Behavior: The RTP sequence number is not continuous from the origin until the end of a SIP call, including the time when the call is on hold.
New Behavior: The RTP sequence number is now continuous from the origin until the end of a SIP call.

Additional Informaiton:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/command/reference/cme_b1ht.html#wp1030564
•
Old Behavior: There is no command to configure Network Time Protocol (NTP) to reject time updates greater than the panic threshold of 1000 seconds.
New Behavior: A new command, ntp panic update, is introduced to configure NTP to reject time updates greater than the panic threshold of 1000 seconds. If the ntp panic update command is configured and the received time updates are greater than the panic threshold of 1000 seconds, the time update is ignored and the following console message is displayed:
NTP Core (ERROR): time correction of -22842. seconds exceeds sanity limit 1000. seconds; set clock manually to the correct UTC time.Additional Information:
http://www.cisco.com/en/US/docs/ios/netmgmt/command/reference/nm_10.html
Cisco IOS Release 15.0(1)M5
The following behavior changes are introduced in Cisco IOS Release 15.0(1)M5:
•
Old Behavior: The default maximum queue-limit on a subinterface was 512 if no hold-queue was configured on the main interface.
New Behavior: As part of HQF, this restriction has been removed. Now the maximum queue-limit can be set as high as the hold-queue size on the main interface.
Additional Information:
http://www.cisco.com/en/US/partner/docs/ios/qos/command/reference/qos_q1.html#wp1075320
•
Old Behavior: Network congestion causes ARP packets to drop because the ARP packet priority is not enabled.
New Behavior: A new command, arp packet-priority enable, was added. Use the arp packet-priority enable command when network congestion causes ARP packets to drop. Enabling ARP packet priority significantly reduces the number of ARP packet drops.
Additional Information:
http://www.cisco.com/en/US/docs/ios/ipaddr/command/reference/iad_arp.html
•
Old Behavior: After a reload of a router, some or all of the BGP address families do not come up. This is because the router is receiving messages from a neighbor that the AFI or SAFI is not supported, and the router does not retry those AFIs. The output of show ip bgp all summary shows the address family in NoNeg or idle state, and it will never leave that state. Typical output looks like:
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd x.x.x.x 4 1 0 0 1 0 0 never (NoNeg)New Behavior: When the router receives a message that the AFI or SAFI is not supported, the router does not simply drop the rejected AFIs or SAFIs from subsequent OPEN messages. Instead, the router retries the AFI/SAFI within the existing OPEN message retry timing sequence, but with an exponential backoff (stopping at 10 minutes) applied to decisions about whether to include a particular AFI/SAFI in an OPEN message. The timing of OPEN messages is not changed. Successful negotiation of the AFI results in a reset of the backoff sequence for future attempts. Also, when a BGP connection collision occurs with a session in the ESTABLISHED state, BGP sends a CEASE notification on the newly opened connection, and a keepalive message on the old connection. The new connection is closed. If the old session was stale, the keepalive causes it to be closed. The neighbor will retry its OPEN message after receiving the CEASE message and waiting a few seconds.
•
Old Behavior: Destination-only traffic classes cannot be controlled when more than one protocol is operating at the border routers.
New Behavior: Destination-only traffic classes can be controlled when more than one protocol is operating at the border routers using dynamic PBR.
Additional Information:
http://www.cisco.com/en/US/docs/ios-xml/ios/pfr/command/pfr-cr-book.html
•
Old Behavior: No error message is generated when BGP neighbors are configured with both an IPv6 address and MPLS send labels (via the neighbor send-label command or via a template). Sending MPLS labels to IPv6 peers is not supported.
New Behavior: An error message is generated when BGP neighbors are configured with both an IPv6 address and MPLS send labels. An example of the error message is:
"%BGP-4-BGP_LABELS_NOT_SUPPORTED: BGP neighbor 2001:DB8:1::2 does not support sending labels."•
Old Behavior: In Cisco IOS Releases 15.0(1)M2 and 12.4(22)T, when a description for a Register Pool contained a space, i.e., "John Doe," the description would disappear after the configuration was reloaded.
New Behavior: Any descriptors containing spaces are now preserved after router reboot. Quotation marks are not mandatory, but can be used if desired.
•
Old Behavior: There is no filtering capability on packets with IP helper-address destinations.
New Behavior: Filtering capability is supported for packets with IP helper-address destinations.
Additional Information:
http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_i1.html
Cisco IOS Release 15.0(1)M4
The following behavior changes are introduced in Cisco IOS Release 15.0(1)M4:
•
Old Behavior: In the ip nat service command, the tcp keyword used along with the sip keyword is used to enable the TCP SIP NAT ALG functionality.
New Behavior: The tcp keyword used along with the sip keyword in the ip nat service command is removed. The TCP SIP NAT ALG functionality is disabled by default.
Additional Information: http://www.cisco.com/en/US/docs/ios/ipaddr/command/reference/iad_nat.html#wp1049948
•
Old Behavior: If a hostname with all numerals is specified, an error is returned and the hostname is not saved.
New Behavior: If an all-numeric hostname is specified, an error will be returned but the numeric hostname will still be saved.
Additional Information: http://www.cisco.com/en/US/docs/ios/fundamentals/command/reference/cf_book.html
•
Old Behavior: To remove the log option from the permit ip any any log command, use the no permit ip any any log and the permit ip any any commands.
New Behavior: To remove the log entry and the user-defined cookie, use the permit ip any any [word] command.
Additional Information: http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_p1.html#wp1077059
•
Old Behavior: An error message is not displayed when you try applying the tunnel interface to a crypto map using the crypto map (interface IPSec) command.
New Behavior: An error message is displayed when you try applying the tunnel interface to a crypto map using the crypto map (interface IPSec) command.
Additional Information: http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_c4.html#wp1060970
•
Old Behavior: GigabitEthernet0/3/0 is up, line protocol is down.
New Behavior: GigabitEthernet0/3/0 is down, line protocol is down.
•
Old Behavior: The Trend Router Provisioning Server (TRPS) does not provide the functionality to turn on or off the TRPS pipeline requests.
New Behavior: The TRPS enables you to turn on or off the TRPS pipeline requests. The pipeline, on, and off keywords are added to the parameter-map type trend-global command.
Additional Information: http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_p1.html#wp1059633
•
Old Behavior: The Right to Use license is not available for technology packages and all features on Cisco ISR G2 platforms.
New Behavior: The Right to Use license is available for technology packages and all features on Cisco ISR G2 platforms, except for the HSEC feature. Use the license accept end user agreement command in global configuration mode to configure a one-time acceptance of the Cisco End User License Agreement (EULA) for all Cisco IOS software packages and features.
Additional Information: http://www.cisco.com/en/US/docs/routers/access/sw_activation/SA_on_ISR.html
Cisco IOS Release 15.0(1)M3
The following behavior changes are introduced in Cisco IOS Release 15.0(1)M3:
•
Old Behavior: Using the domain command and the stripping keyword in dynamic authorization local server configuration mode, a string can be terminated at the first delimiter going from left to right only in order to configure username domain options for the RADIUS application.
New Behavior: In addition to using the domain command and the stripping keyword to terminate at the first delimiter going from left to right only in order to configure username domain options for the RADIUS application, the right-to-left keyword can be added after the domain command and stripping keyword in dynamic authorization local server configuration mode to allow a string to be terminated at the first delimiter going from right to left in order to configure username domain options for the RADIUS application.
Additional Information: The following documents were updated to reflect this change to the domain command:

•
Old Behavior: When cooperative key server key distribution occurs, one KS declares itself as the primary KS, creates a policy, and sends out the policy to the other secondary KS. The secondary KS continues to wait before declaring the primary KS as the primary KS and continues to stay in election mode, but because both the primary and secondary KS have a policy, the GM registration succeeds.
New Behavior: When cooperative key server key distribution occurs, one KS declares itself as primary, creates a policy, and sends the policy to the other secondary KS. The secondary KS declares the primary KS as primary KS when it gets the policy and ends the election mode. The secondary KS now also blocks GM registration while the cooperative key server key distribution is in progress. This change allows the cooperative key server distribution to become more efficient because it saves time. For example, the following syslog warning message is displayed:
00:00:16: %GDOI-5-COOP_KS_BLOCK_NEW_GM_REGISTER_ELECTION: This KS temporarily blocks GM with ip-addr 10.0.4.1 from registering in group diffint as the KS election is underwayAdditional Information: The "Cooperative Key Server" section in the Cisco Group Encrypted Transport VPN feature document was updated to reflect this change:

New Behavior: Long filenames are now truncated to the first six characters and suffixed with "~" followed by a numeral. The numeral changes incrementally if a naming conflict is identified.
•
Old Behavior: BGP selects paths that are not the oldest paths for multipaths. This causes BGP to flap unnecessarily from multipaths to nonmultipaths as a result of route flaps.
New Behavior: BGP uses the best-path selection algorithm to find a set of equally good routes. These routes are the potential multipaths. When there are more equally good multipaths are available than the maximum permitted number, the oldest paths are selected as multipaths.

Additional Information:
•
Old Behavior: Entries in the NAT table cannot be cleared on SNAT backup router for H.323 RAS traffic. This can happen when the NAT table of the primary router is out of sync with the NAT table of the secondary router as an unintended consequence of the asymmetric queuing feature being enabled. This problem does not occur if the asymmetric queuing feature is disabled. Asymmetric routing for SNAT will work properly regardless of whether as-queuing is enabled or disabled.
New Behavior: The as-queuing keyword for the ip nat stateful command has been removed so that the asymmetric queuing cannot be enabled. Any out of sync condition between the NAT table of the primary router and the secondary router caused by network latency will resolve itself in a short amount of time.
•
Old Behavior: An individual entry in the NAT table cannot be cleared. When you enter the clear ip nat translation command you get the following error message:
%Translation in use, cannot removeNew Behavior: NAT entries can be deleted using any of following three CLI changes:

Old Behavior: A breakpoint exception reload occurs when you configure SNMP traps using Cisco Works and the following errors are displayed:
%SNMP-5-WARMSTART: SNMP agent on host is undergoing a warm start %SYS-2-CHUNKFREE: Attempted to free nonchunk memory, chunk ########, data ########. -Process= "NAT MIB Helper", ipl= 0, pid= 277 -Traceback=This symptom is observed after the SNMP server is unconfigured and then configured again. The commands used for this configuration could include snmp-server enable traps or snmp-server community.
New Behavior: The breakpoint does not occur if NAT MIB support is disabled, which is the default setting. If NAT MIB support is enabled by entering the new enable-mib keyword for the ip nat service command, breakpoint exception reloads might occur.
•
Old Behavior: If rekey address is not configured in the GDOI group, the show crypto gdoi ks rekey command reloads trying to access a null pointer.
New Behavior: If the rekey address is not configured in the GDOI group, the show crypto gdoi ks rekey command will show the multicast destination address as "Not Found."
•
Old Behavior: The gateway automatically closes the gateway TCP connection when the remote side TCP connection attempts to overwrite the data on the existing gateway TCP connection.
New Behavior: The gateway uses IP addresses to determine which endpoint to close when TCP connections are opened simutaneously. The gateway TCP connection is closed only if the IP address is smaller.

•
Old Behavior: The snmp-object ED does not support types "oid" and "counter64." This makes it impossible to match on objects such as sysObjectID or ifHCInOctets.
New Behavior: The event snmp-object CLI and the event_register_snmp_object event detector have been reworked to support types "oid" and "counter64." You can now match objects such as sysObjectID or ifHCInOctets.
