Determining the Software Version

To determine the version of Cisco IOS software currently running on your Cisco 800 series router, see About Cisco IOS Release Notes located at http://www.cisco.com/en/US/docs/ios/12_4/12_4x/12_4xy15/ReleaseNote.html.

Upgrading to a New Software Release

For general information about upgrading to a new software release, see About Cisco IOS Release Notes located at http://www.cisco.com/en/US/docs/ios/12_4/12_4x/12_4xy15/ReleaseNote.html.

Embedded Access Point HTML GUI

The Cisco 800 Series ISRs provide HTML GUI access and configuration for the wireless device. First, establish a wireless configuration session to the access wireless device, and then you can access the HTML GUI through a browser using the IP address of the BVI interface. This HTML GUI is based on Cisco Aironet 1250 Access Point's GUI and reflects the same features and functionality. Differences in feature support are noted below:

•Repeater mode is not supported, therefore 'Repeater' has been removed from the GUI.

•WLSE is not supported, therefore the appearance of 'SWAN architecture' on the Wireless Services page, under 'AP' config is removed from the GUI.

•The GigabitEthernet0 interface is internal and can not be shut down, therefore the 'shut down' option for the GigabitEthernet0 interface is removed from the GUI.

---

Note There is an exception with the 'External Antenna Configuration' settings. The Cisco 800 series ISRs have fixed antennas, however the enable option for 'External Antenna Configuration' remains in the GUI, so no action will occur if this option is chosen.

Resolved Caveats - Release 12.4(20)YA3

CSCsu84868 c3845: Error mesg %SYS-2-BADSHARE: Bad refcount in datagram_done.

Symptom    Cisco 3845 experiences trackback error:

Aug 14 12:34:55.960: %SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=7006C010, count=0, -Traceback= 0x61816650 0x60641BD0 0x60C27A80 Aug 17 16:51:45.739: %SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=705985A4, count=0, -Traceback= 0x61816650 0x60641BD0 0x60C27A80

Conditions   The error message occurs on a router running the c3845-adventerprisek9_ivs_li-mz.124-15.T5 image.

Workaround   None.

CSCsy22826 VG224 sending incorrect ssType in 1+ node CUCM cluster.

Symptom    VG224 endpoint does not connect to callback destination, once the callback destination is idle.

Conditions   Multi node cluster and VG224 endpoint is registered with node other then the first node in the cluster.

Workaround   Have VG224 endpoints registered with first node.

Further Problem Description: The activation of the callback is successful. What fails is when the callback destination becomes idle again and the VG224 endpoint gets notified (ring). After the VG224 endpoint goes offhook, the system should automatically connect to the Callback destination.This does not happen and VG224 endpoint gets silence.

Limitations and Restrictions

There are no known limitations or restrictions in this release.
