Missing information with show commands.

BRI L1 not coming up after first call.

On-hook CO battery voltage is too low.

Bisync half-duplex(default mode) hangs connection.

Show Controller missing some options on E1/PRI.

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.

DNs remained as E-164 dial peers on standby gateway.

IP phones cannot perform a network-side ringback if a call originates from a Public Switched Telephone Network (PSTN).

Remove interface FastEther5/0.

BRI Layer 1 T3 timer never times out.

13T: Crash when shutting point-to-point FR serial interface.

Could not remove "interface Vlan xxx" that was previously configured.

Spanning Tree shows all ports in forwarding state.

VLAN configuration in two different modes shows up differently.

VLAN does not show up until a switchport is associated with VLAN.

Trunk port gets assigned to all the VLANs in the device.

13T:Traceback 802F7614 802DE6BC 80303324 ... received during boot

11T/Trom:3660 keeps crashing.

On a dot1q trunk, all multicast hellos are sent to native VLAN.

Unable to configure MGCP T1-CAS/Analog-FXS using command line interface.

The FXS ground start port gets stuck in S_WAIT_RELEASE state.

Catalyst 4224 disconnects the call with reason channel unacceptable.

Check the console signals on Catalyst 4224.

Fax relay is not working.

Catalyst 4224 does not provide power to some ports for IP phones.

Changing configuration from PRI to CAS fails.

Change IPX/SNA image names to conform to IOS convention.

When the Catalyst 4224 is queried for cardIfCardIndex SNMP mib object, it does not return correct values.

Description: SNMP support is not available for the following LEDs on the chassis of Catalyst 4224:

Traceback seen when executing the following command on the Catalyst 4224 Access Gateway Switch:

no switchport trunk allowed vlan x

ccm dial-peer prefix does not work for subsequent downloads.

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.

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.

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.

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.

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.

Description: SNMP query to cpmCPUTotalTable returns incorrect values.

Workaround: None

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

Description: IP address table rows cannot be created or modified using SNMP.

Workaround: None

Description: The rows in ipNetToMediaTable cannot be created or modified using SNMP.

Workaround: None

Description: DiffServe CodePoint (DSCP) marking for voice packets is broken in 12.2(2 ) YC3 image.

Workaround: None

Description: Cannot transfer inbound VoIP calls between IP Phones in SRST mode.

Workaround: None
