Bug Fixes

This section lists bugs that have been fixed or resolved in the various software releases for the Catalyst 4224.

Bug Fixes in Cisco IOS Release 12.1(5)YE2

The following reported bugs have been fixed or resolved in Cisco IOS Release 12.1(5)YE2:

• CSCdu66264

New DSP (3.3.81) with echo canceller fix and FAX relay fix.

• CSCdu68219

Ports do not work after reloading the gateway.

• CSCdu89151

Loss of IP connectivity within the same VLAN of the Catalyst 4224. The Catalyst 4224 connects multiple devices within the same VLAN. At some point, a device can

lose IPconnectivityto other devices connected to the same switch; however,this same deviceretains IP connectivity to the switch itself. Other devices connected directly to this switch lose IP connectivity to the failed device, yet these other devices maintain IP connectivity with each other. Remote devices maintain IP connectivity to all devices connected to the switch.

New and Changed Information

• CSCdv01742

• CSCdv02746

• CSCdv08920

• CSCdv12080

IP phones in fallback mode connected to the Catalyst 4224 are unable to transfer calls. When IP phones are connected to the Catalyst 4224 and they are operating in fallback mode, these

phones lose the ability to transfer calls. If a user tries to transfer to an invalid directory number, the transferring phone receives a reorder tone but is able to resume the original call. However, if the user enters a valid directory number, both the calling phone and the transferring phone are disconnected.

ISDN BRI on the Catalyst 4224 cannot receive calls on the second B-channel. This problem occurs in a Catalyst 4224 with an ISDN BRI interface module. The first B-channel of

the BRI interface module can receive calls, but the second B-channel cannot. When a call is sent to the second B-channel number, the router sees two ISDN SETUP messages approximately 3 seconds apart. For the firstSETUP message, the router does not answer. For the second SETUP message, the router responds with a DISCONNECT with Cause i = 0x80A2 (No circuit/channel available). All the ISDN SETUP messages for both calls contain the channel id = 0x89.

At this point, if someone tries to call the first B-channel number again, the call will not work. You have to perform a shut/no shut to the BRI interface before the first B-channel can receive calls again. In addition, you will have to wait for some time before you can call the router.If you call the firstB-channel right after Layer 2 is up, the router will respond with a DISCONNECT message with Cause i = 0x80AF (Quality of service unavailable). This error occurs because the VTSP still shows that the router is in the S_CONNECT state. Only after a while does the router go back to a normal state, and call can be place to the first B-channel again. This behavior is cyclical.

From the show and debug commands, it appears that the router did not release the CCB for the first call to the first B-channel. The sh isdn status command shows that there are no Layer 3 calls active, but there is still a CCB present for the VOICE. This occurs only after a call is placed to the second B-channel of the BRI interface.

FXO supervisor disconnect fails on incoming calls. Incoming calls to the FXO port may ring a device such as an IP phone connected to the

Catalyst 4224. If the caller goes back on-hook within a few seconds, the called phone continues to ring. The remote on-hook is apparently not being detected.

IP phones are not getting powered up.

Bug Fixes in Cisco IOS Release 12.1(5)YE3

The following reported bugs have been fixed or resolved in Cisco IOS Release 12.1(5)YE3:

• CSCds63736

Important Notes

The following sections contain important notes about Cisco IOS Release 12.1(5)YE3 that can apply to the Cisco Catalyst 4224 Access Gateway Switch.

Hardware Change in Catalyst 4224

Cisco IOS Release 12.1(5)YE3 is being shipped in conjunction with a hardware Engineering Change Order (ECO) for the Catalyst 4224 platform. Cisco IOS Release 12.1(5)YE3 is backward compatible with previous non-ECO hardware versions of the Catalyst 4224.

Note Cisco recommends that you do not run software releases prior Cisco IOS Release 12.1(5)YE3 on the

ECO hardware because serial WICs running in slot 1 might not operate correctly.

You can recognize ECO hardware by running the cookie command from ROMMON and looking at the hardware revision level. All boards with a revision level of 1.3 (Major 01/Minor 03) or greater are ECO hardware.

Limitations and Restrictions

Important Notes

Tighten Screws on VICs and WICs

You must tighten the screws when installing the interface cards in the Catalyst 4224 Access Gateway Switch. If you do not tighten the screws properly, the VIC or WIC can malfunction.

TDM Clocking

The TDM clock reference on the Catalyst 4224 Access Gateway Switch can be derivedfrom one of seven sources. Each VIC slot that contains an E1/T1 card has five free running on-board clock sources and two recovered clock sources.

The default reference is the on-board clock. You can use the frame-clock-select command to select one of the E1/T1 ports as the primary reference. You can also use this command to select up to three prioritized backups if the primary clock fails. Switching over to a backup source is non-revertive. The system does not switch back to a higher priority clock if it recovers after a failure.

The frame-clock-select command has the following syntax:

[no] frame-clock-select priority E1/T1 slot/port

The clock source with priority one is the primary reference and the clock with priority four is the lowest priority backup.

The clock reference selection that uses the frame-clock-select command is independent from the clock selection between lines or internal on an E1/T1 controller. Framing and CRC errors due to clock slips can be observed on E1/T1 interfaces if the on-board clock is used as the reference.

Need to Support 56 Kbps Operation for Slot 3 WIC

The 8260 Rev1A device in the Catalyst 4224 Access Gateway Switch has a defect that can cause data corruption when configuring the MCC SI Ram for 2 entries (7 bits forming the 56-kbps channel and 1 bit being discarded).

As a workaround, 3 SI RAM entries would have to be used, but the Catalyst 4224 Access Gateway Switch does not have enough available space. Therefore, only 64-kbps channels are supported.

If absolutely required, you could implement this feature in slots 1 and 2 using the SCCs and limit it to two channels or super-channels per slot. This feature requires more design work and will not be addressed unless really needed.

Customers that need 56 kbps should use the WIC-56K4 WIC.

Survivable Remote Site Telephony Marks Control Packets Differently

The Survivable Remote Site Telephony software feature marks the control traffic as a 10100000 or dscp of cs5. Non-Survivable Remote Site Telephony IOS software marks it as 01101000.

Important Notes

MTP Not Used on Cisco CallManager Unless Transcoding is Required

All H.323 gateways that use IOS 12.0(7) or later support H.323 Version 2. Prior to H.323 Version2, MTP was required for H.323 gateways. Ordinarily, the MTP box on Cisco CallManager should not be checked when defining the Catalyst 4224 as an H.323 gateway. You should check the MTP box on Cisco CallManager only if transcoding is required at the central site. For example, transcoding would be required when the Catalyst 4224 uses G.729 for IP WAN calls and the voice mail system at central site only supports G.711.

With the MTP box checked on Cisco CallManager for the H.323 gateway definition for Catalyst 4224, a locally connected analog FXS phone call to a local IP phone must traverse the IP WAN because the call between the analog FXS phone and the IP phone is anchored by the transcoding deviceat the central site. This behavior is normal for an IOS H.323 gateway when the MTP box on Cisco CallManager is checked, but this behavior is obviously not optimal. Therefore, unless transcoding is required, the MTP box should not be checked on the H.323 gateway definition for Catalyst 4224.

Connecting the Catalyst 4224 as a Gateway Over a Low Speed Serial Link

Use the h323-gateway voip bind srcaddr command to connect the Catalyst 4224 as a gateway over a low speed serial link.

To configure the Catalyst 4224 as an H.323 gateway, use the following configuration:

interface Loopback1 description h323 gateway address ip address 10.253.1.1 255.255.255.0 h323-gateway voip bind srcaddr 10.253.1.1

This configuration provides the IP address for the H.323 end point. Use the same address in Cisco CallManager to configure the H.323 gateway. This address can be attached to a physical interface.

Portfast Command Not Supported for Trunks

If the Catalyst 422410/100 Ethernet ports are configured in trunk mode, the portfast command is not supported. The workaround is to use the global configuration commands for each VLAN to reduce the forwarding timers to a minimum value of 4 seconds.

spanning-tree portfast bpduguard spanning-tree vlan 60 forward-time 4 spanning-tree vlan 160 forward-time 4

Warning

If you connect the Catalyst 4224 to another switch, ensure that the timers are the same on both links. Otherwise, you might experience spanning tree issues.

OL-1798-01

MTP Not Used on Cisco CallManager Unless Transcoding is Required

Page 8

Important Notes

Use the Portfast Command with a Separate VLAN for Voice and Data

To use the portfast command, configure the Catalyst 4224 ports with an access VLAN for data and a separate VLAN for voice. The following configuration provides an example:

interface FastEthernet5/22 no ip address duplex auto speed auto switchport access vlan 60 switchport voice vlan 160 snmp trap link-status spanning-tree portfast

Note Trunking should be used only to connect to another switch.

Configuring a Single PVC on Frame Relay with CBWFQ

To configurea single PVC on Frame Relay with CBWFQ until LLQ becomes available,see the following notes.

Note LLQ is currently disabled.

The Catalyst 4224 currently supports LLQ/CBWFQ only on a PPP or HDLC encapsulated serial link. The Catalyst 4224 supports LFI on MLPPP links but not LLQ/CBWFQ or ip rtp priority.

LLQ/CBWFQ are not currently supported for Frame Relay. The Service Policy output command is currently disabled. Therefore, currently only ip rtp priority is supported as a voice priority queuing scheme. FRF.12 is also supported on Frame Relay links.

The following configuration example is recommended for FRF.12 and ip priority. Define the map class:

map-class frame-relay VOIP_256 no frame-relay adaptive-shaping frame-relay cir 250000 frame-relay bc 1000 frame-relay be 0 frame-relay mincir 250000 frame-relay fair-queue frame-relay fragment 320 frame-relay ip rtp priority 16384 16383 170

Apply the map class to a frame-relay sub interface:

interface Serial0/0.300 point-to-point ip address 1.1.1.1 frame-relay interface-dlci 300 frame-relay class VOIP_256

Apply frame-relay shaping to the main interface:

interface ser0/0 encapsulation frame-relay frame-relay traffic-shaping

Use the Portfast Command with a Separate VLAN for Voice and Data

IGMP Snooping Support

One or more users might need to connect to local/remote server(s) via IP WAN or other LAN connection to access a MULTICAST application, such as IPTV or WEBCast. The Catalyst 4224 should send the multicast stream only to the requesting user PC and should not flood the rest of user PCs with such streams.

IGMP is a multicast protocol that directly affects PCs (hosts). IGMP allows hosts to inform Layer 3 devices (routers) that they want to receive multicast traffic for a specific multicast group address.

Multicast Address Range

The multicast address range includes any IP address in the range 224.0.0.0 to 239.255.255.255. The range of addresses between 224.0.0.0 and 224.0.0.255 (inclusive) is RESERVED for the use of routing protocols and other low-level topology discovery or maintenance protocols.

Any multicast server defined in the network will be part of one or more multicast groups. Whenevera user’sPC (referred to as host) requests the services of a multicast server,for example, it asks

for an application (such as a movie channel), and it will send a message to join the particular group (join-group) the server uses to multicast (transmit) such movie.

The Catalyst 4224 will send the movie stream only to the hosts that have sent a join request. The Catalyst 4224 keeps track of the multicast entries via two tables known as Multicast address count and IGMP snooping count. As in any system, these tables are finite, and specifically in the Catalyst 4224 their max value is 255. Once this value is reached, further joins (join-group) or VLAN definitions cannot be executed.

Important Notes

Other IGMP Requirements

In order to enable IGMP within the Catalyst 4224, a multicast protocol such as PIM must be configured for the corresponding interface(s), which are mainly VLAN interfaces. The user cannot enable IGMP directly as it is done in other Cisco switches.

TIPS on how to keep track of the multicast tables to prevent them from getting full (based on test observations),

• For every VLAN added to the system, the multicast address count will increase by 4. (IGMP

snooping address Count does not get impacted by VLAN addition.)

• Whenever a multicast protocol is added (for example, ip pim dense-mode) both counters increase

by 3. (The first instance will increase counters by 4 because Multicast group 224.0.1.40 is added too.)

• You can add up to 62 VLANs without IGMP support. Any additional VLAN will get added, but cdp

and EIGRP for these VLANs will not work (among other things).

• When a multicast group is added via the join-group command, both counters are increased by 1.

• When you delete a VLAN interface that was multicasting (for example, pim) no counters get

decreased. (A bug report exists for this issue.)

• When you delete a multicast protocol (for example, no ip pim value) from an interface, the counters

get increased by 1.

• When a multicast group leaves(via the no ip igmp join-group ip-address), both counters get properly

decremented by 1. This is the case when a host finishes using the multicast application, like viewing a movie.

OL-1798-01

IGMP Snooping Support

Page 10

Important Notes

Design

The Catalyst 4224 hardware is designed to support many IGMP groups and VLAN interfaces, as long as the multicast address count is <= 255 and/or IGMP snooping address count is <= 255.

Note When the table limit is exceeded, no friendly message is displayed.

IP Phones Running SRST Fail to Get DHCP Reply

This section explains what happens when the lease time expires for IP phones running Survivable Remote Site Telephony (SRST) that are assigned by the DHCP server in a central site.

IP Phones will try to renew the lease, but they will fail to get any DHCP replies due to the WAN failure. Eventually IP phones will not only lose IP addresses but also lose phone services. Resetting or power cycling the phones will not clear this situation. IP address and phone services cannot be restored until a valid DHCP response is received by the IP Phone or the phone's IP address is manually configured (DHCP is disabled).

When the IP address leased from the DHCP server is not infinite, the DHCP client will start sending DHCP renew messages to extend the lease before the lease expires. When the lease time expires, IP phones will start sending DHCP request messages and go to DHCP init state after a certain amount of time without receiving DHCP replies from the server (this time is configurable). In the case when IP phones already register with the SRST router in Cisco CallManager fall back mode, renewing the IP address request will not be replied unless the SRST router itself is a DHCP server or there is a DHCP server that can be reached. IP phones will lose their IP addresses assigned by the DHCP server in the central site due to WAN failure, and hence lose the phone services, which cannot be recovered until a valid DHCP response is received by the IP phone or the phone's IP address is manually configured, thus disabling the DHCP service.

Note that loosing the lease is not the same as resetting. If the phone resets, it comes up in the INIT-REBOOT state; this is the state where it has an IP address stored in flash. If it cannot contact the DHCP server, it will use its stored address and continue to do DHCP Discovers in the background until the server responds. In the case were the lease expires, the phone clears the IP address stored in flash and goes to the INIT state. It cannot reinitialize until it gets a response from the DHCP server. This behavior is as specified in the DHCP protocol RFC 2131.

Configuring Fractional T1 PRI ISDN

This release supports fractional T1 PRI ISDN on the following switch types:

• DMS-100

• 5ESS

• NI-1

To configure a fractional T1 for PRI ISDN, perform this procedure:

1. Make sure the PRI VIC is configured last (after you configure all the VIC cards that require the DSP

resources).

2. Allocate all 24 timeslots for the PRI group. For example:

controller T1 1/0 framing esf linecode b8zs pri-group timeslots 1-24

Note The DSP resources are not sufficient for the 24 timeslots, and you will receive a message

indicating insufficient DSP resources. You need to configure the switch/PBX to make the timeslots out-of-service. If you do not allocate 24 timeslots, a SERVICE message will not be sent for the unallocated timeslots.

Important Notes

3. Usethe show voice dsp command to check how many channels could be allocated with the available

DSP resources. For example, in one case 16 timeslots could be allocated DSP resources.

4. Busy out the remaining timeslots for which the DSP resources could not be allocated. For example:

isdn service dsl 0 b_channel 17-24 state 2

5. Use the show isdn service to make sure the channel is out-of-service.

c4224#sh isdn ser PRI Channel Statistics: ISDN Se1/0:23, Channel [1-24] Configured Isdn Interface (dsl) 0 Channel State (0=Idle 1=Proposed 2=Busy 3=Reserved 4=Restart 5=Maint_Pend) Channel : 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 State : 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 Service State (0=Inservice 1=Maint 2=Outofservice) Channel : 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 State : 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 2 2 2 2

Now for any incoming call, only timeslots 1-16 will be used by the switch or the PBX.
