Important Notes

Cisco IOS Releases 12.2(2)YC and 12.2(2)YC1 were deferred due to caveat CSCdy01975. The software solution for these deferred images is Cisco IOS Release 12.2(2)YC3, which is available on Cisco.com.

To increase network availability, Cisco recommends that you upgrade affected Cisco IOS images with the suggested replacement software images. Cisco will discontinue manufacturing shipment of affected Cisco IOS images. Any pending order will be substituted by the replacement software images.

Note Please be aware that failure to upgrade the affected Cisco IOS images may result in network downtime.

The terms and conditions that governed your rights and obligations and those of Cisco, with respect to the deferred images will apply to the replacement images.

Caveats

Note MGCP is not supported in this release even though it appears in the documentation and the CLI.

This section lists unresolved caveats that apply to this release of the Cisco Catalyst 4224 Access Gateway Switch. Caveats describe unexpected behavior or defects in the switch and its related software.

CSCdw11594

: PSTN users will not hear Music on Hold (MoH) when a call is placed on hold by an IP phone that is in a G.711 region and the requirement for media termination point (MTP) is selected on the AGM.
: Workaround: The device must have a Software MTP available in its Media Resource Group List.

CSCin04209

: Description: When the Catalyst 4224 is queried for cardIfCardIndex SNMP mib object, it does not return correct values.
: Workaround: None.

CSCin04412

: Description: SNMP support is not available for the following LEDs on the chassis of Catalyst 4224:
: Workaround: None

CSCin04963

: Description: SNMP query to cpmCPUTotalTable returns incorrect values.
: Workaround: None

CSCin06538

: Description: SNMP response for the variable card type returns unknown (1) when the following cards are inserted in the Catalyst 4224:
: Without this variable, these cards cannot be found in Cisco View.
: Workaround: None

CSCin06631

: Description: IP address table rows cannot be created or modified using SNMP.
: Workaround: None

CSCin06633

: Description: The rows in ipNetToMediaTable cannot be created or modified using SNMP.
: Workaround: None

CSCdt16110

: Description: An analog voice port configured with alaw companding port may experience excessive noise. The port also may not recognize DTMF digits in this configuration. Calls can still be received but there will be noise.
: Workaround: Use A-to-u law transcoding at the T1/E1 or VoIP port.

CSCdv29907

: Description: Memory corruption in tplus_encode_ulong. Under unknown conditions, a Cisco router running 12.2(3.4)T or later, and using TACACS+ accounting, may reload due to memory corruption.
: Workaround: Disable TACACS+ accounting.

CSCdv82735

: Description: If IP phones and fast ethernet ports are hard coded for speed and/or duplex, phones will never power up.
: Workaround: Set both IP phone and fast ethernet ports for AUTO negotiation.

CSCdw56572

: Description: Low latency queueing (LLQ) does not drop packets after configuration changes. If the configured LLW burst size is changed in a policy map that is attached to an interface but the configured LLQ bandwidth is not changed, priority queueing (PQ) will stop dropping packets. If the traffic going through PQ is much greater than the configured bandwidth, the minimum bandwidth guarantees of the classes are not met.
: Workaround: Remove and re-attach the service policy.

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
