The WIC-1ADSL-I-DG card is a 1-Port asymmetric digital subscriber line (ADSL) WIC for Cisco modular access routers. This 1-port WIC card allows the co-existence of ADSL and ISDN on the same local loop and provides high-speed ADSL digital data transfer between a single customer premises equipment (CPE) subscriber and a central office. The WIC supports the UR-2 and Annex B G.992.1 technical specifications.
IP Communications Voice/Fax Network Modules
Cisco IOS Release 12.2(15)ZJ introduces new voice/fax network modules that support IP communications. The IP communications voice/fax network modules provide the ability to directly connect the PSTN and legacy telephony equipment to Cisco 3725 and Cisco 3745 modular access routers, enabling important applications such as IP telephony, toll bypass, and full gateway integration.
Voice network modules convert telephone voice signals into a form that can be transmitted over an IP network. These modules have one or two slots for installing supported interface cards. Voice interface cards (VICs) or voice/WAN interface cards (VWICs) installed in the voice network module provide physical connections to the telephony equipment or network.
The new network modules that support this feature are:
•
•
•
The new network modules support the following new VIC2 voice interface cards (VICs):
•
An FXS interface connects directly to a standard telephone, fax machine, or similar device. This interface supplies ringing voltage, dial tone, and so on to the station.
•
An FXO interface connects local calls to a central office or PBX. This is the interface a standard telephone provides.
•
•
E&M is a signaling technique for two-wire and four-wire telephone and trunk interfaces. The E&M interface typically connects remote calls from an IP network to a PBX.
•
The ISDN BRI voice interface card provides a client-side (TE) ISDN S/T physical interface for connection to an NT1 terminating an ISDN telephone network. Each of its two ports can carry two voice calls (one over each ISDN B channel), for a total of four calls per ISDN BRI card.
Note
The new network modules support the following existing VICs and voice WAN interface cards (VWICs):
•
A Direct Inward Dial (DID) voice interface enables a Cisco 2600 series, Cisco 3600 series, or Cisco 1700 series router to provide DID service to extensions on a PBX.

Restrictions
The Cisco ADSL WAN interface cards do not support dual latency, ADSL2, or ADSL2plus.
Cisco IOS MGCP Gateway Support for Cisco CallManager Network Specific Facilities
The Cisco IOS MGCP Gateway Support for Cisco CallManager Network Specific Facilities (NSF) feature is an enhancement to Cisco CallManager functionality. It enables users to configure the NSF ISDN information element of the route pattern.
The ISDN NSF route pattern design has been changed in the Cisco CallManager database to enable invocation of facilities or services on a call-by-call basis.
The NSF information is used in ISDN PRI call setup for outgoing calls and includes carrier identification code (CIC) and service parameters. The NSF configuration tasks are done in Cisco CallManager.
The NSF configuration has been added in the route pattern user interface page for Media Gateway Control Protocol (MGCP) controlled PRI ports. Without the NSF configuration, users have to configure their associated gateways as stand-alone H.323 gateways for which NSF services are configured locally within the router. With NSF configured, NSF can be used on a call-by-call basis.
For additional prerequisite and configuration information, refer to the Cisco IOS MGCP Gateway Support for Cisco CallManager Network Specific Facilities feature module at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122z/122zj15/gt_nsf.htm
Cisco CallManager Express Version 3.0
Cisco CallManager Express (CME) Version 3.0 delivers the next-generation CME feature set. Cisco CME Version 3.0 supports the following enhancements:
•
The CME setup tool provides a question-and-answer interface that allows you to set up an entire Cisco CME system at automatically.
•
The auto assign command specifies a range of extension numbers to which newly discovered IP phones are automatically assigned. This method is useful when you have a phone setup in which each phone is assigned a separate, unique extension number.
•
Call pickup allows phone users to retrieve calls from other extension numbers by using the PickUp soft key and dialing the ringing number. When extensions are assigned to pickup groups, other members of the group can retrieve incoming calls using fewer keystrokes.
•
When night service is active, incoming calls to designated night-service extension numbers will also ring on other phones that are designated as night-service phones. Phone users at the other phones can use call pickup to retrieve the incoming calls.
•
Call blocking to prevent the unauthorized use of phones is implemented by matching calls to a specified digit pattern during a specified time period. Up to 32 patterns of digits can be specified. Individual phones can be exempted from call blocking, and individual user logins can override call blocking if they are configured.
•
Ephone hunt groups provide the ability to direct incoming calls for a specific number (the ephone hunt group pilot number) to a defined group of extensions. Incoming calls are redirected on busy or no answer from extension to extension in the list until they are answered or they reach the number that was defined as the final number.
•
Secondary dial tone is generated when a phone user dials a predefined digit. The tone terminates when additional digits are dialed. For example, you can configure a secondary dial tone to be heard after the number 9 is dialed to reach an external line.
•
The Cisco IP Phone 7902G, is a cost-effective, entry-level IP phone addressing the voice communications needs of a lobby, laboratory, manufacturing floor, or hallway—or other areas where only basic calling capability is required. For further information, go to Cisco.com and click Products & Service, IP Phone, Cisco 7900 Series IP Phones, Product Literature, and Data Sheets or go to: http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/english/ipp7902/index.htm
•
The Cisco IP Phone 7912G provides core business features and addresses the communication needs of a cubicle worker who conducts low to medium telephone traffic. The Cisco IP Phone 7912G offers four dynamic soft keys that guide a user through call features and functions. For further information, go to Cisco.com and click Products & Service, IP Phone, Cisco 7900 Series IP Phones, Product Literature, and Data Sheets.
•
Three types of speed dial are available:
–
–
–
•
Cisco IP Phone 7940 and Cisco IP Phone 7960 users can enter account codes during call setup or while connected to an active call, using the Acct soft key. Account codes are inserted into call detail records (CDRs) on the CME router for later interpretation by billing software.
•
This feature allows callers who dial a busy extension number to request a callback from the system when a called number that was busy is free. Callers can also request callbacks for extensions that do not answer and the system will notify them after the called phone is next used.
This feature is available only on Cisco IP Phone 7940 and Cisco IP Phone 7960.
•
Do not disturb (DND) service is enabled using a soft key on a Cisco IP Phone 7940 or a Cisco IP Phone 7960. When DND is enabled, incoming calls do not ring on the phone, but do provide visual alerting and call information and can be answered if desired. A display message indicates that DND is in effect. Call forwarding on busy and no answer operates the same as without DND.
•
•
•
Certain PSTN services, such as three-way calling and call waiting, require hookflash intervention from a phone user. A new soft key, labeled Flash, has been introduced to provide this functionality for Cisco IP Phone 7940 and Cisco IP Phone 7960 users on FXO lines attached to the CME system. The Flash soft key is enabled using the fxo hook-flash command.
•
Dual-line extensions are available to handle call-waiting, call transfer, or conferencing using a single button.
•
An extension (ephone-dn) overlay allows more than one ephone-dn to use the same physical line button on an IP phone. Overlaid ephone-dns can be used to receive incoming calls and place outgoing calls.
•
The Cisco CME GUI provides a web-based interface to manage most CME system-wide and phone-based features. In particular, the GUI facilitates the routine adds and changes associated with employee turnover, allowing these changes to be performed by non-technical staff.
The CME Graphical User Interface (GUI) provides three levels of access to support the following user classes:
–
–
–
•
The label support feature allows you to enter a meaningful text string to view in the display adjacent to an extension button on an IP phone rather than the extension number that is associated with that button.
•
For multi-button phones and expansion modules, the buttons for extensions that are shared with other phones can be designated as monitor buttons, which show the status of those extensions on the other phones. When not in use, a monitor line can be used with the Transfer soft key to quickly transfer a call.
•
The Cisco CME system automatically creates a local phone directory based on the telephone numbers that are assigned during the configuration of extensions and phones. Additional entries to the local CME directory can be made using the directory entry command.
•
The silent ring feature allows you to designate phone buttons that do not emit an audible ring when they receive incoming calls. Although this feature is supported by all phone types, it is most useful on phone buttons that are used to display the activity of shared lines, which are typically found on the Cisco IP Phone 7960 and Cisco IP Phone Expansion Module 7914.
•
Approximately 35 new and modified commands are described in the Command Reference at: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122z/122zj15/itsv30/its30cmd.htm

SRST Features
The SIP Survivable Remote Site Telephony (SRST) feature describes SRST functionality for Session Initiation Protocol (SIP) networks. SIP-SRST provides backup to an external SIP proxy server by providing basic registrar and redirect services. These services are used by a SIP IP phone in the event of a WAN connection outage and the SIP phone is unable to communicate with its primary SIP proxy. The SIP-SRST device also provides PSTN gateway access for placing and receiving PSTN calls.
SIP-SRST provides four new features:
•
A local SIP gateway that becomes the SIP registrar acts as a backup SIP proxy or redirector, and accepts SIP Register messages from SIP phones. It becomes a location database of local SIP IP phones that are set up for dual-registration. Dual-registration allows SIP IP phones to simultaneously register with both their primary and fallback registrar devices. That is, when a SIP IP phone registers with a SIP-SRST gateway, it simultaneously registers with the main proxy and SIP redirect server for coverage in case of WAN failure. A registrar accepts SIP Register requests and dynamically builds VoIP dial peers allowing the Cisco IOS Voice Gateway software to route calls to SIP phones.
•
Backup registrar service to SIP IP Phones can be provided by configuring a voice register pool on SIP gateways. The voice register pool configuration provides registration permission control and can also be used to configure some dial peer attributes that are applied to the dynamically created VoIP dial peers when SIP Phone registrations match the pool.
•
The call redirect enhancement supports calls from a local SIP phone to another local SIP phone through the Cisco IOS Voice Gateway. Prior to this enhancement, an attempt by a SIP phone to contact another local SIP phone using the Cisco IOS Voice Gateway as if it were a SIP proxy or redirect server would fail. However, now the Cisco IOS Voice Gateway can act as a SIP redirect server. The voice gateway responds to the originator with a SIP Redirect message, allowing the SIP phone that originated the call to establish a call to its destination.
•
Prior to Cisco IOS Release 12.2(15)ZJ, when a call was redirected, the SIP gateway would send a "302 Moved Temporarily" message. The first longest match route on a gateway (dial-peer destination pattern) was used in the Contact header of the 302 message. With release 12.2(15)ZJ, if multiple routes to a destination exist for a redirected number (multiple dial peers are matched), the SIP gateway sends a "300 Multiple Choice" message and the multiple routes in the Contact header are listed.
SIP Gateway Enhancements
SIP Gateway enhancements were also introduced in Cisco IOS Release 12.2(15)ZJ to support the SRST feature for SIP networks. They are:
•
Skinny Client Control Protocol (SCCP) IP phones do not support in-band DTMF digits; they are capable of sending only out-of-band DTMF digits. To support SCCP devices, originating and terminating SIP gateways can now use Cisco proprietary NOTIFY-based out-of-band DTMF relay. NOTIFY-based out-of-band DTMF relay sends messages bidirectionally between the originating and terminating gateways for a DTMF event during a call. In addition, NOTIFY-based out-of-band DTMF relay can be used by analog phones attached to analog voice ports (FXS) on the router.
•
With H.323, Cisco IOS gateways can register E.164 numbers of a POTS dial peer with a gatekeeper, which informs the gatekeeper of a user's contact information. SIP gateways now allow the same functionality, but with the registration taking place with a SIP proxy or registrar. SIP gateways allow registration of E.164 numbers to a SIP proxy or registrar on behalf of analog telephone voice ports (FXS), IP phone virtual voice ports (EFXS), and local SCCP phones.

Cisco Survivable Remote Site Telephony (SRST) Version 3.0
The Cisco SRST Version 3.0 feature supports the following enhancements:
•
The Cisco IP Phone 7902G, is a cost-effective, entry-level IP phone addressing the voice communications needs of a lobby, laboratory, manufacturing floor, or hallway—or other areas where only basic calling capability is required. The Cisco IP Phone 7902G is a single-line IP phone, with fixed feature keys that provide one-touch access to the redial, transfer, conference, and voice-mail access features. Consistent with other Cisco IP phones, the Cisco IP Phone 7902G supports in-line power, which allows the phone to receive power over the LAN. This capability gives the network administrator centralized power control—translating into greater network availability.
For further information, go to Cisco.com and click Products & Service, IP Phone, Cisco 7900 Series IP Phones, Product Literature, and Data Sheets or go to http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/english/ipp7902/index.htm.
•
The Cisco IP Phone 7912G provides core business features and addresses the communication needs of a cubicle worker who conducts low to medium telephone traffic. The Cisco IP Phone 7912G offers four dynamic soft keys that guide a user through call features and functions. The graphic capability of the display provides a rich user experience by providing calling information and intuitive access to features.
The Cisco IP Phone 7912G supports an integrated Ethernet switch, providing LAN connectivity to a colocated PC. In addition, the Cisco IP Phone 7912G supports in-line power, which allows the phone to receive power over the LAN. This capability gives the network administrator centralized power control, translating into greater network availability. The combination of in-line power and Ethernet switch support reduces cabling needs to a single wire to the desktop.
For further information, go to Cisco.com and click Products & Service, IP Phone, Cisco 7900 Series IP Phones, Product Literature, and Data Sheets.
•
The display message that appears on Cisco IP Phone 7905G, Cisco IP Phone 7910, Cisco IP Phone 7940, and Cisco IP Phone 7960 units when they are in fallback mode can be customized. The new system message command allows you to edit these display messages on a per router basis.
•
Cisco SRST V1.0 allowed only blind call transfers, in which a transferring party did not have the ability to announce or consult with a destination party before transferring a call. Cisco SRST V1.0 used a Cisco SRST proprietary mechanism to perform these blind transfers. Cisco SRST V3.0 adds the ability to perform call transfers with consultation or blind using the ITU-T H.450.2 standard for H.323 calls.
•
A new keyword has been added to the max-dn command allows you to set IP phones to dual-line mode. Each dual-line IP phone must have one voice port and two channels to handle two independent calls. This mode enables call waiting, call transfer, and conference functions on a single ephone-dn. Dual-line mode works with all phone types. The max-dn command is a global command that affects all IP phones on an Cisco SRST router.
•
The date format on Cisco IP phone displays can be configured with the following two additional formats:
yy-mm-dd (year-month-day)
yy-dd-mm (year-month-day
•
Cisco SRST can be configured to support continuous multicast output of music-on-hold (MoH) from a Flash MoH file in Flash memory.
•
A ringing timeout default can be configured for extensions on which no-answer call forwarding has not been enabled. Expiration of the timeout causes incoming calls to return a disconnect code to the caller. This mechanism provides protection against hung calls for inbound calls received over interfaces such as foreign exchange office (FXO) that do not have forward-disconnect supervision.
•
The show ephone command has been enhanced to display the following:
–
–
•
Diagnostic messages are added to the system log whenever a phone registers or unregisters from Cisco SRST.
•
Cisco SRST supports three-party ad hoc conferencing using G.711. For conferencing to be available, an IP phone must have a minimum of two lines connected to one or more buttons.
•
Several international languages and call-progress tone sets are newly supported. The set of supported languages varies by phone type.
•
There are approximately 10 new and modified commands. They are described at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122z/122zj15/srs30/srs_cmds.htmFor further information about the SRST Version 3.0 features, refer to the Cisco SRST System Administrator Guide Version 3.0 at the following URL:
Custom Tone Download to Cisco IOS MGCP Gateways from Cisco CallManager
Cisco IOS Release 12.2(15)ZJ introduces the Custom Tone Download to Cisco IOS MGCP Gateways from Cisco CallManager feature. This feature implements the downloading of region-specific tones and the associated frequencies, amplitudes, and cadences using XML-based configuration files during gateway registration. The feature also supports the generation of tones up to four frequencies by the Cisco IOS Media Gateway Control Protocol (MGCP) gateway. The feature supports dual tones and sequential tones.
The MGCP gateway handles the translation between voice signals and the packet network and interacts with Cisco CallManager. Cisco CallManager performs signal and call processing. The Custom Tone Download to Cisco IOS MGCP Gateways from Cisco CallManager feature enables the gateway to use the tone information in the custom tone tables that have been downloaded from the TFTP server in an XML-based configuration file.
When Cisco CallManager requests a specific tone, the gateway references the custom tone table associated with the network locale of the voice port.
When the gateway registers to Cisco CallManager, or if the gateway restarts or resets, the network locale for each port is downloaded to the gateway. Once the custom tone specification is downloaded to the gateway, it can also be used in H.323 mode if the gateway loses connectivity to Cisco CallManager.
This feature supports one new Cisco IOS command and three modified Cisco IOS commands:
•

•
•
For additional command syntax information, prerequisite and configuration information, refer to the Custom Tone Download to Cisco IOS MGCP Gateways from Cisco CallManager feature module at:
Restrictions
Only one gateway supports the download of up to two custom tones, that is, no more than two custom tone tables will be downloaded to one gateway even if there are more that two countries or regions configured for the gateway.
DPNSS Backhaul
This feature introduces support for Digital Private Network Signaling System (DPNSS) Layer 2 functionality on the Cisco gateway (GW) for Cisco IOS Release 12.2(15)ZJ. This feature supports layer 3 backhauling to a Cisco PGW2200 using DPNSS and Digital Access Signaling System (DASS) User Adaptation (DUA) over Stream Control Transmission Protocol (SCTP).
DPNSS was developed by British Telecom and is used in the United Kingdom and some parts of Europe. DPNSS is a standard and open protocol used between PBXs in a private network that enables complex features to work on a network basis. This feature applies the DPNSS backhaul solution on Cisco gateways to provide connectivity and services to the PBXs running the DPNSS protocol.

MGCP-Controlled Backhaul of BRI Signaling
The Media Gateway Control Protocol (MGCP)-Controlled Backhaul of Basic Rate Interface (BRI) Signaling in Conjunction with Cisco CallManager feature is introduced on the Cisco 2600 series in Cisco IOS Release 12.2(15)ZJ.
The Media Gateway Control Protocol (MGCP)-Controlled Backhaul of Basic Rate Interface (BRI) Signaling in Conjunction with Cisco CallManager feature provides MGCP service to remote-office media gateways that connect by means of ISDN BRI trunks to a centralized Cisco CallManager media-gateway controller for the purpose of call processing. D-channel signal information is backhauled to the call manager through a Transmission Control Protocol (TCP) session.
Should connection to the primary call manager fail, call processing reverts to a backup call manager until the connection to the primary is restored. Should connections to the primary and all backups fail, call processing reverts to H.323 on the media gateway. When a connection is restored, call processing reverts to the primary or other available call manager and to MGCP.
Feature benefits include the following:
•

IOS fw allowing forged packets for a session initiated from inside
A vulnerability in the Transmission Control Protocol (TCP) specification (RFC793) has been discovered by an external researcher. The successful exploitation enables an adversary to reset any established TCP connection in a much shorter time than was previously discussed publicly. Depending on the application, the connection may get automatically re-established. In other cases, a user will have to repeat the action (for example, open a new Telnet or SSH session). Depending upon the attacked protocol, a successful attack may have additional consequences beyond terminated connection which must be considered. This attack vector is only applicable to the sessions which are terminating on a device (such as a router, switch, or computer) and not to the sessions that are only passing through the device (for example, transit traffic that is being routed by a router). In addition, this attack vector does not directly compromise data integrity or confidentiality.
All Cisco products which contain TCP stack are susceptible to this vulnerability.

as5300 crashed in MultiBitDecode
Cisco products running IOS contain vulnerabilities in the processing of H.323 messages, which are typically used in packetized voice or multimedia applications. Features such as NAT and IOS Firewall must inspect H.323 messages and may be vulnerable as well. A test suite has been developed by the University of Oulu to target this protocol and identify vulnerabilities.
Support for the H.323 protocol was introduced in Cisco IOS Software Release 11.3T, and all later Cisco IOS releases are affected if configured for various types of Voice/Multimedia Application support. The vulnerabilities can be exploited repeatedly to produce a denial of service (DoS).
There are workarounds available that may mitigate the impact, but these techniques may not be appropriate for use in all customer networks.

H323 crashes in strncpy when receiving invalid setup packet
Cisco products running IOS contain vulnerabilities in the processing of H.323 messages, which are typically used in packetized voice or multimedia applications. Features such as NAT and IOS Firewall must inspect H.323 messages and may be vulnerable as well. A test suite has been developed by the University of Oulu to target this protocol and identify vulnerabilities.
Support for the H.323 protocol was introduced in Cisco IOS Software Release 11.3T, and all later Cisco IOS releases are affected if configured for various types of Voice/Multimedia Application support. The vulnerabilities can be exploited repeatedly to produce a denial of service (DoS).
There are workarounds available that may mitigate the impact, but these techniques may not be appropriate for use in all customer networks.

Symptoms: The gateway is not sending RSIP:restart when the digital voice-ports are configured as Media Gateway Control Protocol (MGCP) endpoints. Because of this, the call agent is not informed of the status of the MGCP endpoints and it rejects the NTFY messages from the gateway.
Workaround: After configuring the MGCP endpoints for the digital-port, perform the following in the configuration mode to restart the MGCP application:
Router(config)# no mgcpRouter(config)# mgcpThis should make the router send RSIP:restart to the call agent.

Unable to set the H.323 callIdentifier from Tcl IVR script
Symptoms: Call setup to an IP network may be delayed or rejected.
Further Problem Description: A call setup without an incoming call leg results in a H.225 SETUP or remote access server (RAS) admission message with the callIdentifier field value of zeroes.
Conditions: TCL IVR script attempts to set up a call without specifying the incoming leg.
Workaround: The workarounds are:
1. Set up a call with an incoming leg.
2. Enter set callinfo(newguid) to force the call setup to generate new conferenceID and callIdentifier fields. This assumes that the generated GUID does not affect the billing system or the remote endpoint.
Example:
set callinfo(newguid) trueleg setup $dest_nr callinfoCSCeb71588
Digital MGCP endp doesnt become active after creation till mgcp res

corrupted packet can cause input queue wedge - reg to CSCdx02283
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.

CSCea22283
Wrong voice mail box selected when call fwded across multiple phones
Symptoms: Caller reaches original destination's voicemail when forwarded-to destination is not available.
Conditions: If a call is forwarded across multiple IP phones, the voicemail box selected is that of the originally called number.
For example: A calls B and the call is forwarded to C. C does not answer and the call gets forwarded to B's voice mail (instead of C's voicemail).
Workaround: There is no workaround.
CSCea87260
dpnss: channels not kept in OOS when E1 controller/serial int down
Symptoms: The DLCs end up in the "IDLE" state even though there is a shutdown on the controller/interface.
Conditions: When there is a shutdown on the controller/interface and PGW requests GW to bring up the DLCs.
Workaround: There is no workaround.
CSCeb01098
Release Source not being set by new Session app
Symptoms: The Release Sources reported in the radius accounting record or the gateway's call history record for the incoming and outgoing legs don't match. This behavior does not affect the voice call.
Conditions: This behavior may occur when the default voice application handles the incoming call.
Workaround: Configure the application default.c.old command on the incoming dial-peer used for the call.
CSCuk42484
wrong cause value when transferring to busy/unallocated number
Symptoms: The wrong cause value is provided when transferring a call to an unallocated or busy destination.
Conditions: This behavior can occur when an incoming call VoIP call is handled by the app-h450-transfer.2.0.0.3.tcl application.
The gateway will place an outbound VoIP call instead of disconnecting the incoming call with the appropriate cause code under the following two conditions:
•
•
In this case, the final cause value returned to the incoming call will depend on the outgoing call setup request.
Workaround: There is no workaround.
CSCuk43681
call mishandled when calling an unallocated number
Symptoms: Congestion tone is not provided to the caller when a call setup attempt fails with cause 'Temporary Failure'(41 / 0x29).

CSCdz59865
Routed port back to L2 port and unnumbered serial interface.
Symptoms: Changing a routed port back to a L2 port causes a serial interface to be left configured with the IP unnumbered command while the routed port interface no longer exists.
Conditions: Configure a serial interface with ip unnumbered fastether 1/0 where the fastether 1/0 is a routed port. Then change back the routed port to L2 port (switched port).
This leaves the serial interface configured with ip unnumbered fastether1/0, but there is no interface (routed port) with a valid IP addresses.
Workaround: Don't use the Unnumbered command.
CSCdz72542
storm-control and no storm-control become global mode
Symptoms: Incomplete Storm control CLI will switch configuration mode to global mode rather than per port Storm control configuration mode.
Conditions: Configuring the no storm-control command in interface configuration mode.
Workaround: Use the no storm-control broadcast | unicast | multicast command instead of just the no storm-control command in interface configuration mode.
CSCdz76940
Fast switching not working on Routed Port.
Symptoms: Routed port does not fast-wswitch IP traffic although router is configured for IP fast-switching
Conditions: Configure IP fast switching.
Workaround: There is no workaround.
CSCdz87738
show isdn status does not retrieve all info
Symptoms: Output of the show isdn status command doesn't display the isdn status information of all the isdn interfaces.
Conditions: The problem appears only when one of the interfaces is configured with a switch type of primary-dpnss.
Workaround: Use the show isdn status <serial-interface-number> command to get the output of an individual interface.
