Cisco Cisco IOS Software Release 12.4(23) Notas de publicación

Conditions: This symptom is observed on a Cisco 2811 router with ATM interface that is using 
VWIC2-2MFT-T1/E1 connected to MGX AUSUM card.

Workaround: Enter the shutdown interface configuration command followed by the no shutdown 
interface configuration command on the IMA interface.

Symptoms: The latency for the RSH command could increase when they are flowing through an 
FWSM module.

Conditions: The following issue was observed on an FWSM that is running 2.2 (1) software. The 
long delay was triggered by using either Cisco IOS Release 12.3(13a)BC1 or Release 12.3(17a)BC1 
on routers toward which those RSH commands were sent.

Workaround: Either bypass the FWSM module or downgrade to Cisco IOS Release 12.3(9a)BC3 
which is not affected by this extra delay issue. 

Cisco IOS Release 12.4(7g) is a rebuild release for Cisco IOS Release 12.4(7). The caveats in this 
section are resolved in Cisco IOS Release 12.4(7g) but may be open in previous Cisco IOS releases.

Symptoms: A router that is configured for QoS may reload unexpectedly or other serious symptoms 
such as memory corruption may occur.

Conditions: This symptom is observed on a Cisco router that has a cable QoS profile with a name 
that has a length that is greater than 32 characters as in the following example:

cable qos profile 12 name g711@10ms_for_any_softswitch_Traa^C

                          00000000011111111111222222222333^ 

                          12345678901234567890123456789012|

                                                          |

                                                       PROBLEM

                                                      (Variable Overflowed).

Workaround: Change the name of the cable QoS profile qos profile to a length that is less than 32 
characters.

Symptoms: When running double auth crypto (ah encap and esp encap auth together) configurations 
and passing large packet data which requires fragmentation, errored packets can be observed.

Conditions: This symptom has been observed on routers with AIM-VPN-PLUS AIM cards installed. 
Routers which support this AIM are Cisco 1800, Cisco 2600, Cisco  2800, Cisco 3700, and 
Cisco 3800 routers.

Workaround: Do not use ESP and AH double authentication, or use the no crytpo engine accel 
command in the configuration to run encryption in the software engine.

Symptoms: The gateway in SRST gets IP phones registered and it attempts to register them to the 
gateway as E.164 numbers.
