1 The number in the "In" column indicates the Cisco IOS release in which the interface was introduced. For example, (1) means that an interface was introduced in Cisco IOS Release 12.1(1) XD. If a cell in this column is empty, the interface was included in the initial base release.
New and Changed Information
The following sections list the new hardware and software features supported by the Cisco AS5350 for Cisco IOS Release 12.1(3) XQ4.
New Hardware and Software Features in Cisco IOS Release 12.1(3)XQ4
No new hardware and software feature are supported by the Cisco AS5350 for Cisco IOS Release 12.1(3) XQ4.
New Hardware and Software Features in Cisco IOS Release 12.1(3)XQ3

There are no new hardware features in the Cisco AS5350 for Cisco IOS Release 12.1(3)XQ.
New Software Features in Cisco IOS Release 12.1(3)XQ
The following new software feature is supported by the Cisco AS5350 for Cisco IOS Release 12.1(3)XQ:
Managing Port Services on the Cisco AS5350 Universal Gateway
The Managing Port Services feature implements port service management for the Cisco AS5350 universal gateway using the NextPort dial feature card (DFC). The NextPort DFC is a hardware card that processes digital service port technology for the Cisco AS5350. The ports on the NextPort DFC support both modem and digital services. Ports can be aggregated at the slot level of the NextPort module, the Service Processing Element (SPE) level within the NextPort module, and the individual port level. A port is defined as an endpoint on a DFC card through which multiservice tones and data flow.
Instead of the traditional line/modem one-to-one correspondence, lines are mapped to an SPE that resides on the Cisco AS5350 NextPort DFC. Each SPE provides modem services for six ports. Busyout and shutdown can be configured at the SPE or port level. The NextPort DFC introduces the slot and SPE software hierarchy.
Limitations and Restrictions
The MICA and microcom modems are not supported on the Cisco AS5350. Only modem and digital services are supported by using the NextPort dial feature card.
MIBs
Current MIBs
To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
Deprecated and Replacement MIBs
Old Cisco MIBs will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 4.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
This section contains only open and resolved caveats for the current Cisco IOS maintenance release.
All caveats in Cisco IOS Release 12.1 and Cisco IOS Release 12.1 T are also in Cisco IOS Release 12.1(3) XQ4.
For information on caveats in Cisco IOS Release 12.1 T, see Caveats for Cisco IOS Release 12.1 T.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats and select severity 3 caveats for Cisco IOS Release 12.1 and is located on Cisco.com and the Documentation CD-ROM.
Note

All the caveats listed in this section are resolved in Cisco IOS Release 12.1(3) XQ3. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
Cisco IOS software contains a flaw that permits the successful prediction of TCP Initial Sequence Numbers.
This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.
To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in DDTS record CSCds04747.
Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(3) XQ3.
•
When virtual private dial-up network (VPDN) calls are made, the Cisco AS5350 will reload unexpectedly. There is no workaround.
This is resolved in Cisco IOS Release 12.1(3) XQ3.
