New Software Features in Cisco IOS Release 12.2(11)YZ1
There are no new software features supported by the Cisco 7000 family for Cisco IOS Release 12.2(11)YZ1.
New Hardware Features in Cisco IOS Release 12.2(11)YZ
The following new hardware features are supported in Cisco IOS Release 12.2(11)YZ:
7300-CC-PA
Platforms: Cisco 7304 routers
The 7304 Peripheral Component Interconnect (PCI) port adapter carrier card (7300-CC-PA) makes it possible to use Cisco 7200 series and Cisco 7500 series PCI port adapters on the Cisco 7304 router.
The Cisco 7304 router hosts centralized processing on a network services engine (NSE) or network processing engine (NPE). The 7300-CC-PA acts as a pass-through device so that the NSE or NPE processes all packets from a PCI port adapter installed on a Cisco 7304.
The 7300-CC-PA supports one single-width port adapter.
Cisco 7301 Router Platform
Platforms: Cisco 7301 routers
The Cisco 7301 router provides application-specific features for broadband subscriber aggregation and network application services with high processing performance.
Each Cisco 7301 router consists of the following features:
•
1.73 in. x 17.3 in. x 13.87 in. (4.39 cm x 43.9 cm x 35.23 cm). The weight is approximately 10.5 lbs (4.76) kg).•

Cisco 7304 Router Platform
Platforms: Cisco 7304 routers
The Cisco 7304 router is a high-performance Enterprise Edge LAN/WAN integration and service provider aggregation router.
The Cisco 7304 router supports the following features:
•
•
•
•
•
The Cisco 7304 router uses high speed point-to-point serial link technology to interconnect the processor card (NSE) and each line card. An NSE provides connectivity to three physical Ethernet ports, two Gigabit Ethernet ports and one FastEthernet/Ethernet management port.
A fully configured Cisco 7304 router comes equipped with one AC-input power supply that supplies 540w of power to the router. A Cisco 7304 router, however, can operate two power supplies on a single chassis. The additional power supply provides a hot-swappable, load-sharing redundant power supply. Redundant power is useful as a fail-over; if a situation occurs where one power supply is down (for instance, a power supply fails or a new power supply needs to be installed), the router can continue to run properly using the other power supply.
New Software Features in Cisco IOS Release 12.2(11)YZ
The following new software feature is supported in Cisco IOS Release 12.2(11)YZ:
New Quality of Service Features for PXF
Platforms: Cisco 7304 routers
The following Quality of Service features were introduced for Parallel eXpress Forwarding in this IOS release.
•
•
•
•
•
•
•
•
•
•
Beginning in Cisco IOS Release 12.2(11)YZ, there is no longer a reserved queue for priority traffic. A queue will be designated for priority traffic based on the configuration of a priority class. One queue is still reserved for the default class traffic, and one queue is reserved for critical locally-sourced traffic (such as keepalives and routing protocol hellos), thus leaving six user configurable queues (including one for priority).
For additional information on these and other PXF features on the Cisco 7304 router, see the Cisco 7304 Troubleshooting and Configuration Notes document.
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.
Important Notes
Image Deferral, Cisco IOS Release 12.2(11)YZ1
All Cisco 7300 series crypto images in Cisco IOS Release 12.2(11)YZ have been deferred to Cisco IOS Release 12.2(11)YW1 due to the following caveat:
•

Note
Open Caveats—Cisco IOS Release 12.2(11)YZ2
This section documents possible unexpected behavior by Cisco IOS Release 12.2(11)YZ2 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
This is fix is require to avoid port flap on connected GE ports.
There are no known workarounds.
Resolved Caveats—Cisco IOS Release 12.2(11)YZ2
All the caveats listed in this section are resolved in Cisco IOS Release 12.2(11)YZ2. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available.
Cisco has made software available, free of charge, to correct the problem.

This section documents possible unexpected behavior by Cisco IOS Release 12.2(11)YZ1 and describes only severity 1 and 2 caveats and select severity 3 caveats.
There are no known open caveats for Cisco IOS Release 12.2(11)YZ1.
Resolved Caveats—Cisco IOS Release 12.2(11)YZ1
All the caveats listed in this section are resolved in Cisco IOS Release 12.2(11)YZ1. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
The OAM managed PVCs may be down forever after interface shutdown and no shutdown are executed, if the PVCs are configured under subinterfaces on PA-A3-T3/PA-A3-E3 with C7300-PA-CC board. Another shutdown / no shutdown on the interface may resolve the problem.
The problem does not happen with every shutdown / no shutdown operation. The cause of the problem is that the data path is sometimes blocked following shutdown / no shutdown and the OAM cells do not pass through. The problem has been fixed.
There are no known workarounds.
Open Caveats—Cisco IOS Release 12.2(11)YZ
This section documents possible unexpected behavior by Cisco IOS Release 12.2(11)YZ and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
The router will crash when configuring stm-1 port adapter. This occurs when two routers are connected back-to-back in IOS configuration mode when applying "clock source internal".
Workarounds: Shutdown the controllers on both routers and then configure both controllers and serial interfaces, and then no shutdown controller.
•
Issuing a break key at a certain point in order to bring the router into a rommon mode will cause the router to reset. This occurs when the router starts to boot or reload.
Workaround: Issue the break key after the following line is displayed C7301 platform with 262144 Kbytes of main memory
•
Change stopbits configuration under line console 0 will lose connection to the router console until "write memory" command is issued either from a telnet session or AUX port. This occurs when changing the Console port's stopbit value hile consoled into the router via console port.
Workaround: Do not change Console port stopbit value when accessing the router from Console port.
Alternative workaround: To restore Console port connection, either telnet to the router or access the router via Aux port then issue "write memory" command.
Resolved Caveats—Cisco IOS Release 12.2(11)YZ
All the caveats listed in this section are resolved in Cisco IOS Release 12.2(11)YZ. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
There are no known resolved caveats for Cisco IOS Release 12.2(11)YZ.
