Cisco IOS Software Packaging

The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing. Beginning with 12.2(53)SG2, we support the Enterprise Services image on Supervisor Engine 6L-E.

The IP Base image supports Open Shortest Path First (OSPF) for Routed Access, Enhanced Interior Gateway Routing Protocol (EIGRP) "limited" Stub Routing, Nonstop Forwarding/Stateful Switchover (NSF/SSO), and RIPv1/v2. The IP Base image does not support enhanced routing features such as BGP, Intermediate System-to-Intermediate System (IS-IS), Internetwork Packet Exchange (IPX), AppleTalk, Virtual Routing Forwarding (VRF-lite), GLBP, and policy-based routing (PBR).

Cisco IOS Release 12.2(46)SG1 introduced a new LAN Base software and an IP upgrade image. These complement the existing IP Base and Enterprise Services images. The LAN base image is supported on Supervisor Engine 6L-E starting with Cisco IOS Release 12.2(52)XO. LAN Base image is primarily focused on customer access and Layer 2 requirements and therefore many of the IP Base features are not required. The IP upgrade image is available if at a later date you require some of those features.

Starting with Cisco IOS Release 15.0(2)SG, on the Catalyst 4500 Series Switch, support for NEAT feature has been extended from IP Base to LAN Base and support for HSRP v2 IPV6 has been extended from Enterprise Services to IP Base.

Starting with Cisco IOS Release (3.3.0SG or 15.1(1)SG), support for IP SLAs and NSF have been extended from Enterprise Services to IP Base.

Cisco Classic IOS Release Strategy

Customers using Supervisor Engine 6-E or 6L-E with Catalyst 4500 Series Switches who need the latest hardware and software features should migrate to Cisco IOS Release 15.1(2)SG.


Note This release does not support older Supervisor Engines, including II+, III, IV, V, and V-10GE.


The Catalyst 4500 Series Switch has three maintenance trains: 12.2(53)SGx, 15.0(2)SGx, and 15.1(2)SGx. Cisco IOS Release 15.0(2)SG is the recommended release for customers who require a release with a maintenance train.

Figure 1 displays the three active trains, 12.2(53)SG, 15.0(2)SG, and 15.1(2)SG.

Upgrading the System Software

In most cases, upgrading the switch to a newer release of Cisco IOS software does not require a ROMMON upgrade. However, if you are running an early release of Cisco IOS software and plan to upgrade, refer to the following tables for the minimum Cisco IOS image and the recommended ROMMON release, respectively.


Note You must upgrade to at least ROMMON Release 12.2(44r)SG5 to run Cisco IOS Release 15.1(2)SG on the Supervisor Engine 6-E and Supervisor Engine 6L-E. 12.2(44r)SG9 is recommended.



Caution Most supervisor engines have the required ROMMON release. However, due to caveat CSCed25996, we recommend that you upgrade your ROMMON to the recommended release.

The following sections describe how to upgrade your switch software:

Identifying an +E Chassis and ROMMON

An +E chassis is identified by a FRU minor value in the chassis' idprom.

When supervisor engine 1 (sup1) is in ROMMON and supervisor engine 2 (sup2) is in IOS, only sup2 can read the idprom contents of chassis’ idprom. Chassis type is displayed as “+E” in the output of the show version command. Conversely, sup1 can only display the chassis type as “E.”

When both sup1 and sup2 are in ROMMON, both engines can read the chassis’ idprom. Chassis type is displayed correctly as “+E” in the output of the show version command.

When both sup1 and sup2 are in IOS, both engines can read the chassis’ idprom. Chassis type is displayed correctly as “+E” in the output of the show version command.

Upgrading the Cisco IOS Software


Caution To avoid actions that might make your system unable to boot, please read this entire section before starting the upgrade.

Before you proceed, observe the following rules for hostname:

  • Do not expect case to be preserved

Uppercase and lowercase characters look the same to many internet software applications. It may seem appropriate to capitalize a name the same way you might do in English, but conventions dictate that computer names appear all lowercase. For more information, refer to RFC 1178, Choosing a Name for Your Computer.

  • Must start with a letter and end with a letter or digit.
  • Interior characters can only be letters, digits, and hyphens; periods and underscores not allowed.
  • Names must be 63 characters or fewer; hostname of fewer than 10 characters is recommended.
  • On most systems, a field of 30 characters is used for the host name and the prompt in the CLI. Longer configuration mode prompts may be truncated.

To upgrade the Cisco IOS software on your Catalyst 4500 series switch, use this procedure:


Step 1 Download Cisco IOS Release 15.1(2)SG from Cisco.com, and place the image on a TFTP server in a directory that is accessible from the supervisor engine that is upgraded.

Step 2 Use the dir bootflash: command to ensure that there is sufficient space in Flash memory to store the promupgrade image. If there is insufficient space, delete one or more images, and then enter the squeeze bootflash: command to reclaim the space.

If you are using a CompactFlash card, use slot0: instead of bootflash.

Step 3 Download the software image into Flash memory using the copy tftp command.

The following example shows how to download the Cisco IOS software image cat4000-is-mz.121-12c.EW from the remote host 172.20.58.78 to bootflash:

Switch# copy tftp: bootflash:
Address or name of remote host [172.20.58.78]?
Source filename [cat4000-is-mz121_12c.EW]?

Step 8 Use the show version command to verify that the new Cisco IOS release is operating on the switch.


 

Limitations and Restrictions

These sections list the limitations and restrictions for the current release of Cisco IOS software on the Catalyst 4500 series switch.

  • Starting with Release IOS XE 3.3.0SG and IOS 15.1(1)SG, the seven RP restriction was removed.
  • A Span destination of fa1 is not supported.
  • The "keepalive" CLI is not supported in interface mode on the switch, although it will appear in the running configuration. This behavior has no impact on functionality.
  • TDR is only supported on interfaces Gi1/1 through Gi1/48, at 1000BaseT under open or shorted cable conditions. TDR length resolution is +/- 10 m. If the cable is less than 10 m or if the cable is properly terminated, the TDR result displays "0" m. If the interface speed is not 1000BaseT, an "unsupported" result status displays. TDR results will be unreliable for cables extended with the use of jack panels or patch panels.
  • The following guidelines apply to Fast UDLD:

Fast UDLD is disabled by default.

Configure fast UDLD only on point-to-point links between network devices that support fast UDLD.

You can configure fast UDLD in either normal or aggressive mode.

Do not enter the link debounce command on fast UDLD ports.

Configure fast UDLD on at least two links between each connected network device. This reduces the likelihood of fast UDLD incorrectly error disabling a link due to false positives.

Fast UDLD does not report a unidirectional link if the same error occurs simultaneously on more than one link to the same neighbor device.

  • A XML-PI specification file entry does not return the desired CLI output.

The outputs of certain commands, such as show ip route and show access-lists, contain non-deterministic text. While the output is easily understood, the output text does not contain strings that are consistently output. A general purpose specification file entry is unable to parse all possible output.

Workaround (1):

While a general purpose specification file entry may not be possible, a specification file entry might be created that returns the desired text by searching for text that is guaranteed to be in the output. If a string is guaranteed to be in the output, it can be used for parsing.

For example, the output of the show ip access-lists SecWiz_Gi3_17_out_ip command is this:

Extended IP access list SecWiz_Gi3_17_out_ip
10 deny ip 76.0.0.0 0.255.255.255 host 65.65.66.67
20 deny ip 76.0.0.0 0.255.255.255 host 44.45.46.47
30 permit ip 76.0.0.0 0.255.255.255 host 55.56.57.57
 

The first line is easily parsed because access list is guaranteed to be in the output:

<Property name="access list" alias="Name" distance="1.0" length="-1" type="String" />
 

The remaining lines all contain the term host. As a result, the specification file may report the desired values by specifying that string. For example, this line

<Property name="host" alias="rule" distance="s.1" length="1" type="String" />
 

will produce the following for the first and second rules

<rule>
deny
</rule>
 

and the following for the third statement

<rule>
permit
<rule>
 

Workaround (2):

Request the output of the show running-config command using NETCONF and parse that output for the desired strings. This is useful when the desired lines contain nothing in common. For example, the rules in this access list do not contain a common string and the order (three permits, then a deny, then another permit), prevent the spec file entry from using permit as a search string, as in the following example:

Extended MAC access list MACCOY
permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 appletalk
permit any host 65de.edfe.fefe xns-idp
permit any any protocol-family rarp-non-ipv4
deny host 005e.1e5d.9f7d host 3399.e3e1.ff2c dec-spanning
permit any any
 

The XML output of show running-config command includes the following, which can then be parsed programmatically, as desired:

<mac><access-list><extended><ACLName>MACCOY</ACLName></extended></access-list></mac>
<X-Interface> permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 appletalk</X-Interface>
<X-Interface> permit any host 65de.edfe.fefe xns-idp</X-Interface>
<X-Interface> permit any any protocol-family rarp-non-ipv4</X-Interface>
<X-Interface> deny host 005e.1e5d.9f7d host 3399.e3e1.ff2c dec-spanning</X-Interface>
<X-Interface> permit any any</X-Interface>
 
  • Although the Catalyst 4500 series switch still supports legacy 802.1X commands used in Cisco IOS Release 12.2(46)SG and earlier releases (that is, they are accepted on the CLI), they do not display in the CLI help menu.
  • Current IOS software cannot support filenames exceeding 64 characters.
  • All software releases support a maximum of 32,768 IGMP snooping group entries.
  • Although you can configure subsecond PIM query intervals on Catalyst 4500 platforms, such an action represents a compromise between convergence (reaction time) and a number of other factors (number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route, etc.). You must account for those factors when configuring subsecond PIM timers. We recommend that you set the PIM query interval to a minimum of 2 seconds. By adjusting the available parameters, you can achieve flawless operation; that is, a top number of multicast routes per given convergence time on a specific setup.
  • With Cisco IOS Release XE 3.2.1SG, memory configuration is enabled:
Switch(config)# memory ?
chunk chunk related configuration
free free memory low water mark
record configure memory event/traceback recording options
reserve reserve memory
sanity Enable memory sanity
 

This configuration had been removed erroneously in a prior release.

  • The Catalyst 4510R switch does not support Supervisor Engines 6L-E. Installing an unsupported supervisor engine causes unpredictable hardware behavior that cannot be controlled by the software. Using an unsupported supervisor engine in a redundant slot might cause a supported supervisor engine in the other slot to malfunction.
  • The MAC address table is cleared while you switch between supervisor engines if either the 802.1s or 802.1w Spanning Tree Protocol is configured. To minimize address clearing and subsequent packet flooding, configure the edge ports as spanning-tree portfast and the link type as spanning-tree link-type point-to-point.
  • IP classful routing is not supported; do not use the no ip classless command; it will have no effect, because only classless routing is supported. The command ip classless is not supported because classless routing is enabled by default.
  • A Layer 2 LACP channel cannot be configured with the spanning tree PortFast feature.
  • Netbooting using a boot loader image is not supported.
  • When you deploy redundant supervisors in a Catalyst 4507R, for hardware that does not exist while the startup configuration file is being parsed, the configuration file for the hardware is not applied.

For example, if the active supervisor engine is in slot 1, and you have configured interface Gi1/1, the supervisor engine in slot 2 becomes active if you remove the active supervisor engine from the chassis. In addition, while the startup configuration file is being parsed, you will receive an error message indicating that interface Gi1/1 is no longer present. This behavior is correct. When the formerly active supervisor engine is reinserted into slot 1, there is no configuration for interface Gi1/1.

This situation will not occur when both supervisor engines are physically in the chassis.

Workaround: Copy the startup configuration file into the running configuration:

Switch# copy startup-config running-config
 
  • An unsupported default CLI for mobile IP is displayed in the HSRP configuration. Although this CLI will not harm your system, you might want to remove it to avoid confusion.

Workaround: Display the configuration with the show standby command, then remove the CLI. Here is an example of show standby GigabitEthernet1/1 command output:

switch(config)# interface g1/1
switch(config)# no standby 0 name (0 is hsrp group number)
 
  • For HSRP preempt delay to function consistently, you must use the standby delay minimum command. Be sure to set the delay to more than 1 hello interval, thereby ensuring that a hello is received before HSRP leaves the initiate state.

Use the standby delay reload option if the router is rebooting after reloading the image.

  • When you attempt to run OSPF between a Cisco router and a third party router, the two interfaces might get stuck in the Exstart/Exchange state. This problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces do not match. If the router with the higher MTU sends a packet larger than the MTU set on the neighboring router, the neighboring router ignores the packet.

Workaround: Ensure that the MTUs match.

  • You can run only .1q-in-.1q packet pass-through with Supervisor Engine 6-E.
  • For PVST and Catalyst 4500 E-Series switch VLAN, Cisco IOS Release 12.1(13)EW support a maximum of 3000 spanning tree port instances. If you want to use more instances, use MST rather than PVST.
  • Because the Supervisor Engine 6-E supports the FAT filesystem, the following restrictions apply:

The verify and squeeze commands are not supported.

The rename command is supported in FAT file system.

For Supervisor Engine 6-E, the rename command is available for bootflash and slot0. For all other supervisor engines, the rename command is supported for nvram devices only.

The fsck command is supported for slot0 device. It is not supported in the file systems on supervisor engines other than 6-E.

In the FAT file system, the IOS format bootflash: command erases user files only. It does not erase system configuration.

The FAT file system supports a maximum of 63 characters for file/directory name. The maximum for path length is 127 characters.

The FAT file system does not support the following characters in file/directory names:{}#%^ and space characters.

The FAT file system honors the Microsoft Windows file attribute of read-only and read-write, but it does not support the Windows file hidden attribute.

Supervisor Engine 6-E uses the FAT file system for compact flash (slot0). If a compact flash is not formatted in FAT file system (such as compact flash on a supervisor engine other than 6-E), the switch does not recognize it.

  • If an original packet is dropped because of transmit queue shaping or sharing configurations, a SPAN packet copy can still be transmitted on the SPAN port.
  • All software releases support a maximum of 16,000 IGMP snooping group entries.
  • To maximize performance, use the no ip unreachables command on all interfaces that are configured for ACLs.
  • The threshold for the Dynamic Arp Inspection err-disable function is set to 15 ARP packets per second per interface. You should adjust this threshold depending on the network configuration. The CPU should not receive DHCP packets at a sustained rate greater than 1000 pps.
  • If you first configure an IP address or IPv6 address on a Layer 3 port, then change the Layer 3 port to a Layer 2 port with the switchport command, and finally change it back to a Layer 3 port, the original IP/IPv6 address is lost.
  • In a redundant system, do not remove and reinsert the standby supervisor engine while the active supervisor engine is booting. Doing so may cause the online diagnostics test to fail.

Workaround: Remove and reinsert the standby supervisor engine after the active supervisor engine boots. (CSCsa66509)

  • The switchport private-vlan mapping trunk command supports a maximum of 500 unique private VLAN pairs. For example, 500 secondary VLANs could map to one primary VLAN, or 500 secondary VLANs could map to 500 primary VLANs.
  • Support for PoE depends on the use of the following line cards and power supplies.

PoE switching modules:

WS-X4148-RJ45V

WS-X4224-RJ45V

WS-X4248-RJ45V

WS-X4248-RJ21V

WS-X4524-GB-RJ45V

WS-X4548-GB-RJ45V

WS-X4648-RJ45V-E

WS-X4648-RJ45V+E

WS-X4548-GB-RJ45V+

PoE enabled power supplies:

PWR-C45-1300ACV

PWR-C45-1400DC

PWR-C4K-2800AC

PWR-C45-1400AC

PWR-C45-1300ACV

PWR-C45-6000ACV

  • If a Catalyst 4500 series switch requests information from the Cisco Secure Access Control Server (ACS) and the message exchange times out because the server does not respond, a message similar to this appears:
00:02:57: %RADIUS-4-RADIUS_DEAD: RADIUS server 172.20.246.206:1645,1646 is not responding.
 

If this message appears, ensure network connectivity exists between the switch and the ACS. Also check that the switch has been properly configured as an AAA client on the ACS.

  • For IP Port Security (IPSG) for static hosts, the following apply:

As IPSG learns the static hosts on each interface, the switch CPU may achieve 100 percent if there are a large number of hosts to learn. The CPU usage will drop after the hosts are learned.

IPSG violations for static hosts are printed as they occur. If multiple violations occur simultaneously on different interfaces, the CLI displays the last violation. For example, if IPSG is configured for 10 ports and violations exist on ports 3,6, and 9, the violation messages are printed only for port 9.

Inactive host bindings will appear in the device tracking table when either a VLAN is associated with another port or a port is removed from a VLAN. So, as hosts are moved across subnets, the hosts appear in the device tracking table as inactive.

Autostate SVI does not work on EtherChannel.

  • When IPv6 is enabled on an interface with any CLI, you might see the following message:
% Hardware MTU table exhausted
 

In such a scenario, the IPv6 MTU value programmed in hardware differs from the IPv6 interface MTU value. This occurs if no room exists in the hardware MTU table to store additional values.

To create room, unconfigure some unused MTU values. Then, either disable or re-enable IPv6 on the interface, or reapply the MTU configuration.

  • To stop IPSG with static hosts on an interface, use the following commands in interface configuration submode:
Switch(config-if)# no ip verify source
Switch(config-if)# no ip device tracking max
 

To enable IPSG with static hosts on a port, enter the following commands:

Switch(config)# ip device tracking ****enable IP device tracking globally
Switch(config)# ip device tracking max <n> ***set an IP device tracking maximum on int
Switch(config-if)# ip verify source tracking [port-security] ****activate IPSG on port

Caution If you configure the ip verify source tracking [port-security] interface configuration command on a port without enabling IP device tracking globally or setting an IP device tracking maximum on that interface, IPSG with static hosts reject all the IP traffic from that interface.


Note The preceding condition also applies to IPSG with static hosts on a PVLAN host port.


  • uRPF supports up to four paths. If a packet arrives at one of the valid VLANs that is not programmed as one of the RPF VLAN in hardware, it is dropped. If traffic may arrive from any other interfaces without RPF configured, it can be switched.
  • Input and output ACLs cannot override or filter traffic received on an uRPF interface.
  • No CLI command exists to reflect uRPF drop packets during hardware switching. The sh ip traffic and show cef int commands do not reflect uRPF drops.
  • IPv6 ACL is not supported on a switchport. IPv6 packets cannot be filtered on switchports using any of the known methods: PACL, VACL, or MACLs.
  • Class-map match statements using match ip prec | dscp match only IPv4 packets, whereas matches performed with match prec | dscp match both IPv4 and IPv6 packets.
  • IPv6 QoS hardware switching is disabled if the policy-map contains IPv6 ACL and match CoS in the same class-map with the IPv6 access-list has any mask within the range /81 and /127. This situation causes forwarding packets to software, which efficiently disables the QoS.
  • When the following data-only Catalyst 4500 linecards are used in a Catalyst 4507R-E or 4510R-E chassis with Supervisor Engine 6-Es, the capacity of the power supply may be exceeded:

WS-X4148-FX-MT Cisco Catalyst 4500 Fast Ethernet Switching Module, 48-port 100BASE-FX (MT-RJ)

WS-X4448-GB-RJ45 Cisco Catalyst 4500 48-port 10/100/1000 Module (RJ-45)

The Catalyst 4503-E and Catalyst 4506-E have no caveats. The Catalyst 4507R-E configurations that use power supplies rated at 1400 W or above also have no caveats.

The following replacement switching modules will not exceed the power supply capacity for any Catalyst 4500-E chassis:

Refer to the Catalyst 4500 Series Module Installation Guide to determine the power requirements for all of the Catalyst 4500 linecards and the power capacities of the Catalyst 4500 power supplies.

  • Supervisor Engine 6-E only supports Catalyst 4500 Series linecards in slots 8-10.
  • If you remove a line card from a redundant switch and initiate an SSO switch-over, then reinsert the line card, all interfaces are shutdown. The remaining configuration on the original line card is preserved.

This situation only occurs if a switch reached SSO before you removed the line card.

  • On Supervisor Engine 6-E, upstream ports support flow control auto negotiation in 1G mode only, and flow control is forced in 10G mode. If the interface is configured to auto-negotiate the flow control, and the interface is operating in 10G mode, the system forces flow control to ON and does not auto-negotiate.
  • Supervisor Engine 6-E supports fast UDLD on a maximum of 32 ports.
  • With Cisco IOS Release 12.2(53)SG3 (and 12.2(54)SG), we changed the default behavior such that your single supervisor, RPR, or fixed configuration switch does not reload automatically. To configure automatic reload, you must enter the diagnostic fpga soft-error recover aggressive command. (CSCth16953)
  • Energywise WOL is not “waking up” a PC in hibernate or standby mode.

Workaround: None. CSCtr51014

  • The ROMMON version number column in the output of show module command is truncated.

Workaround: Use the show version command. CSCtr30294

  • IP SLA session creation fails randomly for various 4-tuples.

Workaround: Select an alternate destination or source port. CSCty05405

  • The system cannot scale to greater than 512 SIP flows with MSP and metadata enabled.

Workaround: None. CSCty79236

  • On the following linecards running IOS Release 15.0(2)SG3:

48 10/100/1000BaseT Premium POE E Series WS-X4648-RJ45V+E (JAE14310RHU)

6 Sup 6-E 10GE (X2), 1000BaseX (SFP) WS-X45-SUP6-E (JAE13104VVY)

the following restrictions apply:

Sub-interfaces are not supported on 1 Gigabit and Ten-Gigabit interfaces.

Port-channel members do not support multiple classification criteria for a QoS policy.

CEF is disabled automatically when uRFP is enabled and TCAM is fully utilized.

  • When you enter the ip http secure-server command (or if the system reads it from the startup configuration), the device searches for a persistent self-signed certificate during boot up.

If such a certificate does not exist and the device's hostname and default_domain are set, then a persistent self-signed certificate is generated.

If such a certificate exists, the FQDN in the certificate is compared with the current device's hostname and default_domain. If either differs from the FQDN in the certificate, the existing persistent self-signed certificate is replaced with a new one with the updated FQDN. Be aware that the existing key pair is used in the new certificate.

On a switch that supports redundancy, the generation of the self-signed certificate occurs independently on the active and the standby supervisor engines, and the certificates differ. After switchover, the HTTP client that holds the old certificate cannot connect to the HTTPS server.

Workaround: Reconnect. CSCsb11964

  • When policing IEEE 802.1Q tagged non-IP traffic and calculating traffic conformance, the policer excludes the four bytes that constitute the 802.1Q tag even when you enter the
    qos account layer2 encapsulation command.

Workaround: None. CSCsg58526

  • When hard-coded duplex and speed settings are deleted after an interface shuts down, an a- is added to the duplex and speed in the output from the show interface status command.

This does not affect performance.

Workaround: Enter the no shutdown command. CSCsg27395

  • When a transceiver is removed rapidly from one port and placed in another on the same chassis, occasionally a duplicate seeprom message appears and the port is not able to handle traffic.

Workaround: Remove the transceiver from the new port and place it in the old port. After the SFP is recognized in the old port, remove it slowly and insert it in the new port. (CSCse34693)

  • When performing an ISSU upgrade and the versions of the active and standby supervisor engines differ, you see the following message in the standby supervisor engine console:
%XDR-6-XDRINVALIDHDR: XDR for client (CEF push) dropped (slots:2 from slot:3 context:145 length:11) due to: invalid context
 

Workaround: None. This is an informational message. CSCsi60898

  • An IP unnumbered configuration is lost after a switch reloads.

Workarounds: Do one of the following:

After a reload, copy the startup-config to the running-config.

Use a loopback interface as the target of the ip unnumbered command.

Change the CLI configuration so that during bootup the router port is created first.

CSCsq63051

  • In SSO mode, when a port channel is created, deleted, and recreated on an active supervisor engine with the same channel number, the standby port channel state goes out of sync. After a switch over, the following message displays:
%PM-4-PORT_INCONSISTENT: STANDBY:Port is inconsistent:
 

Workaround: When the port channel starts to flap, enter shut and no shut on the port channel. After the first switchover and after deleting the port channel, create a new channel. CSCsr00333

  • When you remove a line card containing ports configured with IGMP snooping while booting a standby supervisor engine, the active supervisor engine does not synchronize this configuration to the standby supervisor engine as a part of a bulk synchronization. When you reinstall the line card, the configuration in the active and standby supervisor engines will differ.

Workaround: Do one of the following:

Reload the standby switch again with the line card in place.

Remove and reenter the commands on the active supervisor engine. The standby supervisor engine will acquire this change. CSCsv44866

  • After posture validation succeeds, the following benign traceback messages may appear after you unconfigure the global RADIUS and IP device tracking commands:
%SM-4-BADEVENT: Event 'eouAAAAuthor' is invalid for the current state 'eou_abort': eou_auth 4.1.0.101 Traceback= 101D9A88 10B76BB0 10B76FE0 10B7A114 10B7A340 1066A678 106617F8
%SM-4-BADEVENT: Event 'eouAAAAuthor' is invalid for the current state 'eou_abort': eou_auth 4.1.0.102 Traceback= 101D9A88 10B76BB0 10B76FE0 10B7A114 10B7A340 1066A678 106617F8
 

This applies to classic or E-series Catalyst 4500 supervisor engines running
Cisco IOS Release 12.2(50)SG

Workaround: None. CSCsw14005

  • The host's MAC address is not synchronized to the standby supervisor engine after you unconfigure 802.1X on the port and reconnect the host to a IP phone (with CDP port status TLV support) that is connected to the switch.

If the switch were to run a supervisor switchover while in this state, the host's MAC address would not be present in the new active supervisor engine’s MAC address table, causing possible connectivity interruption on the host.

Workaround: Enter the shutdown command, followed by the no shutdown command on the interface. This triggers relearning and synchronizing of the host's MAC to the standby supervisor engine. CSCsw91661

  • On a wireless control system (WCS), some device information is incorrectly displayed for PCs sitting behind an lldp-med capable phone. Specifically, WCS displays the phone's serial number, model number, and software version in the PC's device information. All other information about the PC is correctly displayed on WCS.

This only happens when the switch is running network mobility service protocol (nmsp). It does not happen if the phone is CDP enabled.

Workaround: Use the VLAN ID or name to differentiate the IP phone and the PC sitting behind the phone on the WCS.

The IP phone is detected on the voice VLAN, and the displayed information of serial number, model number, and software version is correct. However, a PC sitting behind the phone is detected on a data VLAN, and the displayed device information is wrong and should be ignored.

  • If time is not specified in the link debounce command, the default value depends on the supervisor engine. The default is 10 mS for a Catalyst 4900M switch, Supervisor Engine 6-E, and Supervisor Engine 6L-E. The default is 100 mS for all other supervisor engines.

Despite the different default value, you can configure any value in the time range.

Workaround: None. CSCte51948

  • On a peer interface on a Catalyst 4948E Ethernet Switch, if errdisabled mode flap detection is set to a very small number (such as 2 flaps in 10 sec), a 10GE link flap may cause the peer interface to enter the errdisabled state.

Workarounds: The Cisco switch default link-flap detection value is 5 flaps in 10 seconds. Use the default value or larger numbers. CSCtg07677

  • After you have enabled EPM logging and the client is authenticated via MAB or Webauth, the value of AUTHTYPE is DOT1X in EPM syslog messages irrespective of the authentication method.

Similarly, the show epm sessions command always displays the authentication method as DOT1X.

Workaround: To view the authentication method used for a client, enter the
show authentication sessions command. CSCsx42157

  • With CFM enabled globally as well as on an ingress interface, CFM packets received on the interface are not policed with hardware control plane policing.

Workaround: None. CSCso93282

  • When either the RADIUS-server test feature is enabled or RADIUS-server dead-criteria is configured, and either RADIUS-server deadtime is set to 0 or not configured, the RADIUS-server status is not properly relayed to AAA.

Workaround: Configure both dead-criteria and deadtime.

radius-server dead-criteria
radius-server deadtime

  • Occasionally, if you use an X2 SR transceiver on a WS-X4706-10GE running
    Cisco IOS Release 12.2(40)SG, you observe CRC errors after a reload or power cycle upon inserting the card or X2.

Workaround: Reinsert the X2. CSCsk43618

  • Uplinks go down when you upgrade the ROMMON of an WS-X45-SUP6-E supervisor from version 12.2(40r)SG1 to a later version.

This behavior occurs in a redundant switch when the active supervisor engine is running Cisco IOS, the standby supervisor engine is in ROMMON, and the standby supervisor engine’s ROMMON is upgraded from version 0.34 or to a later version. The upgrade process causes the uplinks on the standby supervisor engine to go down but the active supervisor engine is unaware of this.

Workarounds: To resume normal operation, do one of the following:

Reload both supervisor engines with the redundancy reload shelf command.

Power-cycle the standby supervisor engine by briefly pulling it from the chassis.

There is no workaround for the link flap issue. CSCsm81875

  • Changing the flow control configuration with traffic and pause frames causes some traffic loss.

This problem can happen when pause frames are sent to a switch port and the flow control receive configuration is toggled on a 10-Gigabit Ethernet port.

Workaround: Change the flow control receive configuration when no traffic exists. CSCso71647

  • When you configure vlan dot1q tag native globally on Supervisor Engine 6-E, MST control packets are tagged on egress on the native VLAN. This conflicts with 802.1s. The Cisco 7600 Series router drops its MST proposal agreements (because it expects the native VLAN MST control packets to be untagged), causing 30 seconds of traffic loss while spanning tree converges.

Workaround: Disable native VLAN tagging on the trunk port of the switch by entering the
no switchport trunk native vlan tag command. CSCsz12611

  • If a large number of VLAN mappings are configured, a member port might fail to join a port channel and no warning is issued.

Workaround: Reduce the number of VLAN mappings. CSCtn56208

  • If an interface whose IP address is being used as the router ID is deleted or shuts down, and you configure a service group with a multicast group address, packet redirection to CE stops and packets are forwarded directly to the destination.

Workaround: Unconfigure and reconfigure the service group. CSCtn88087

  • Global WCCP service configuration fails to enable (WCCP global configuration is accepted but nvgen fails) on a newly deployed switch if the switch is not enabled for SVI or a Layer 3 interface.

Workaround: Enable a Layer 3 interface in the running configuration. CSCsc88636.

  • If you use the quick option in the issu changeversion command, the following might occur:

Links flap for various Layer 3 protocols.

A traffic loss of several seconds is observed during the upgrade process.

Workaround: Do not use the quick option with the issu changeversion command. CSCto51562

  • When you enter the ip pim register-rate-limit command, the following error message displays:
'Failed to configure service policy on register tunnel' and 'STANDBY:Failed to configure service policy on register tunnel'.
 

Workaround: None. The ip pim register-rate-limit command does not function. CSCub32679

  • For packets with the same ingress and egress Layer 3 interface, ingress QoS marking policy does not work.

Workaround: Turn off ICMP redirect through the ip redirect command. CSCua71929

  • While configuring an IPv6 access-list, if you specify hardware statistics as the first statement in v6 access-list mode (i.e. before issuing any other v6 ACE statement), it will not take effect. Similarly, your hardware statistics configuration will be missing from the output of the show running command.

You will not experience this behavior with IPv4 access lists.

Workaround: During IPv6 access-list configuration, configure at least one IPv6 ACE before the "hardware statistics" statement. CSCuc53234

  • When an IPv6 FHS policy is applied on a VLAN and an EtherChannel port is part of that VLAN, packets received by EtherChannel (from neighbors) are not bridged across the local switch.

Workaround: Apply FHS policies on a non EtherChannel port rather than a VLAN. CSCua53148

  • Memory allocation failures can occur if more than 16K IPv6 multicast snooping entries are present.

Workaround: None. CSCuc77376

  • For any configuration where the source-interface keyword is used, if you provide an SVI that is associated with a secondary private VLAN, configuration involving the secondary VLAN may be lost when the switch is reloaded. In such scenarios, always use the primary private VLAN.
  • When you connect two PoE-capable Catalyst 4648 or 4748 modules with straight-through copper cabling, the link may flap, and you may observe incorrect PoE status. If the port belongs to an EtherChannel, it will repeatedly unbundle, then bundle.

Workarounds:

Use a crossover cable.

Enter the diagnostic dpm-discovery-disable module m command provided you are running Cisco IOS Release 15.1(2)SG or higher. CSCub74707

  • When performing an ISSU upgrade from a release prior to Cisco IOS 15.1(2)SG to release Cisco IOS 15.1(2)SG or higher, dynamic ACLs are lost after the first switchover.

Workaround: Enter shut then no shut on any port to restart the authentication session and restore the ACL. CSCul20163

  • When performing an ISSU between any releases prior to Cisco IOS 15.1(1)SG or 3.3.0SG to release Cisco IOS 15.1(1)SG (or 3.3.0SG) or higher, a switch performing multicast routing may persistently drop traffic after the upgrade completes. You can recover multicast traffic by reloading the chassis. Alternately, you can remove all multicast configuration prior to ISSU, and add it back when ISSU completes. CSCuj42672

Open Caveats for Cisco IOS Release 15.1(2)SG4

This section lists the open caveats for Cisco IOS Release 15.1(2)SG4:

  • When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the header is computed for DOT1X/RADIUS accounting messages.

A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2 uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting message, and the client marks the server as unresponsive.

Workaround: None. You must disable 802.1X accounting. CSCts26844

  • When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a flow.

Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.

Workaround: None. CSCts20229

  • When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps, ciscoBfdSessUp and ciscoBfdSessDown, are not generated.

Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration command. CSCtx51561

  • Configuring an interface as unidirectional with the unidirectional send-only | receive-only command still allows an interface to send (configured as Send-only Unidirection Ethernet mode) or receive (configured as Receive-only Unidirection Ethernet mode) packets in a bidirectional mode.

Workaround: None. CSCui10480

  • A device in a Guest VLAN that is connected behind a phone capable of 2nd-port-TLV, experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.

Workaround: None. CSCto46018

  • If burst is not explicitly configured for a single rate policer, the show policy-map command displays an incorrect burst value.

Workaround: Enter the show policy-map interface command to find the actual burst value programmed. CSCsi71036

  • If an EtherChannel is a member of a FlexLink pair, then static MAC addresses configured on the EtherChannel are not moved to the alternate port when the EtherChannel fails (FlexLink failure).

Workaround: None. CSCsq99468

  • VTP databases do not propagate through promiscuous trunk ports. If only promiscuous trunks are configured, you will not see the VLAN updates on the other switches in the VTP domain.

Workaround: Configure an ISL/dot1q trunk port. CSCsu43445

  • When you run Cisco IOS Release 12.2(53)SG1, 12.2(50)SG6, or later releases and configure switchport block multicast on a switch, Layer 2 multicast is not blocked. IPv4 and IPV6 unknown multicast traffic is blocked.

Prior to Cisco IOS Release 12.2(53)SG1 and 12.2(50)SG6, the switchport block multicast command blocks IP Multicast, Layer 2 multicast, and broadcast traffic. CSCta61825

Workaround: None CSCtb30327

  • WCCP service is not reacquired when a service group with a multicast group address is unconfigured, and then reconfigured.

Workaround: Configure IP multicast routing globally and establish IP PIM sparse dense mode on the CE-facing interface. CSCtl97692

  • When a CFM Inward Facing MEP (IFM) is configured on a VLAN that is not allocated on a switch port that is DOWN, the show ethernet cfm maintenance-points local command displays the IFM CC Status as inactive. When you allocate the VLAN, the CC-status remains inactive.

You only see this behavior if you initially did not allocate a VLAN before you configure the IFM, and then later allocate the same VLAN.

Workaround: Unconfigure, and then reconfigure the IFM on the port.

  • After performing an ISSU from Cisco IOS Release 3.2.3 to 3.2.7, multicast packet loss is observed after both supervisor engines are running IOS Release 3.2.7

Workaround: Do a switchover. CSCuo18934

  • On a VSS active switch, devices (i.e., hosts, phones, or workstations) directly connected to ports Gi1/7/38, Gi1/7/39, Gi1/7/40, Gi1/7/43 on VLAN 34 cannot reach the internet or server.

Workaround: None. CSCun83237

  • Occasionally, when netflow sampling is enabled, LACP requires about 60-70 sec until members are bundled.

Workaround: Disable netflow sampling. CSCtg00542

  • Upon adding a new static MAC entry on a Catalyst 4500X VSS running version 3.4.3 and 3.5.x, the switch number is truncated in the running config. Although the entry functions as expected, it displays incorrectly. Upon reload, it encounters an error because the entry is no longer a valid switch, module, or port.
4500x_vss(config)#mac address-table static 03bf.ac10.0cb9 vlan 1 interface Te1/2/3
 
4500x_vss#show run | i mac add
mac address-table static 03bf.ac10.0cb9 vlan 1 interface Te2/3 <--- Missing the 1/
 

Upon reload, the config errors out

mac address-table static 03bf.ac10.0cb9 vlan 1 interface Te2/3
^
% Invalid input detected at '^' marker.
 

Workaround: After a reload, manually re-add the static entry into the running config. CSCuo60703

  • A Catalyst 4507R chassis might experience a watchdog NMI crash. Crashdump is not saved when the supervisor [engine] module reboots.

Workaround: None CSCum54321

  • In a scaled setup, if a QoS policy (with policer action) is attached to numerous targets and if you attempt to modify the policer rates, a switch crashes.

Workaround: Remove the policy from the targets to which it is attached, modify the policy, and re-attach. CSCum58148

  • After disabling DTP on a port-channel, the BLK port goes into FWD state.

This caveat applies to IOS Release 3.04.02.SG, 3.04.03.SG, and 3.04.04SG.

Workaround: None. CSCum91811

  • Given an interface configured for LACP and OAM, when the connection between ASR9K(IOS XR) and a Catalyst 4500X(IOS XE) flaps, the link will not restore due to the following deadlock:

LACP PDU requires OAM to start on the ASR9K side; OAM PDU requires LACP to start on the Catalyst 4500X side. With the above scenario, after a flap the link gets stuck in (Suspended) LACP state on the Catalyst 4500X and in Non-connected state on the ASR9K.

To avoid this behavior, you must manually reconfigure the particular sequence.

Workarounds:

Change the configuration sequence on the 4500X side, such that the LACP packet goes first, followed by OAM PDU:

interface x/x
shut
no oam ethernet
no channel-group <x> active
no shut
channel-group <x> active
oam ethernet
 

Disable EFD on the ASR9K side.

Toggle OAM on ASR9K side. CSCun11927

  • If active traffic exists on switch ports and you configure mac address-table static xxxx.xxxx.xxxx vlan X drop, the switch crashes.

Workaround: None. CSCun13984

  • When the NI port of a laptop without AC power (i.e., operating only on battery mode) is connected to the PoE module (WS-X4748-RJ45V+E), the NIC link does not come up (i.e., remains in disconnected status).

Neither issuing shut then no shut nor disabling then re-enabling the NIC port resolves the problem.

Workarounds:

Configure power inline never on the PoE port.

Use AC power. CSCuo26307

  • With following topology, odd size packets are dropped if traffic egresses on uplink ports of a Catalyst 4948-E switch operating at 1 Gig line rate:

IXIA(01/02) ------ (Gi1/2)C4948E(Ten1/49) ------ (05/02)IXIA

It's easier to observe this output drop with smaller random size packets.

The cos value is set 0.

Workaround: None. CSCun22906

  • After resetting the line cards (WS-X4748-UPOE+E and WS-X4748-RJ45-E ) and issuing the no shut command, port inconsistent error messages display.
*Apr 2 11:37:25.288: %PM-4-PORT_INCONSISTENT: STANDBY:Port Gi7/1 is inconsistent: IDB state down (set 00:00:03 ago),
link: down (00:34:57 ago), admin: down (00:33:33 ago).
 

Functionality is not impacted.

Workaround: None. CSCuo08546

  • When you apply a QoS Service policy simultaneously (under port-vlan config mode) on numerous VLANs with a service policy from Layer 2 to Layer 3, CPU Hog and Trace back display.

Workaround: Reapply the configurations after converting the port. CSCuo24626

  • If Flexlink is configured on a standalone neighboring Catalyst 4500 switch that is connected to VSS, on reloading the switch, Traceback is seen and the switch hangs

Workaround: Remove Flexlink from the neighboring Catalyst 4500 switch. CSCun90931

  • A switch may crash due to an interaction with PIM.

The exact triggers are unknown.

Workaround: None. CSCuo37416

  • When ip igmp mroute-proxy is configured and you reload the switch, it will remove the command:
interface Vlan14
ip address 10.1.1.1 255.255.255.252
ip pim sparse-mode
ip igmp mroute-proxy Vlan2137
end
 
48 Gigabit Ethernet interfaces
2 Ten Gigabit Ethernet interfaces
511K bytes of non-volatile configuration memory.
 
ip igmp mroute-proxy Vlan2137
^
% Invalid input detected at '^' marker.
 

Workaround: Reapply the configuration when the switch reboots. CSCum71764

Resolved Caveats in Cisco IOS Release 15.1(2)SG4

This section lists the resolved caveats in Cisco Release 15.1(2)SG4:

  • When you configure open authentication and perform SSO, the spanning tree state and MAC address are not synchronized to the new standby supervisor engine. This behavior interrupts traffic only after the second switchover because the new standby supervisor engine possesses the wrong state after the initial switchover and the second switchover starts the port in the blocking state.

Workaround: Enter shut and no shut on the port to synchronize the STP state. CSCtf52437

  • Before large PACLs are fully loaded in hardware, you might observe a false completion messages like the following:
Dec 1 18:44:59.926: %C4K_COMMONHWACLMAN-4-HWPROGSUCCESS: Input Security: pacl - now fully loaded in hardware *Dec 1 18:44:59.926: %C4K_COMMONHWACLMAN-4-ALLACLINHW: All configured ACLs now fully loaded in hardware - hardware switching / QoS restored.
 

Workaround: No functional impact.

You must wait for the ACLs to be programmed before performing other TCAM related changes. CSCtd57063

  • When you have two Layer 3 CE-facing interfaces, each connected to a CE to split WCCP between the CEs, and you move a WCCP service (such as 60 (ftp-native)) from one interface to the other, the target interface fails to completely transfer the service from the old to the new CE.

Workaround: Shut down the CE-facing interface. After all of the mask-value entries point to the target CE, unshut the CE-facing interface. CSCtl09941

  • A switch crashes on receiving a malformed LLDP packet.

LLDP should be enabled.

Workaround: None. CSCun66735

  • Upon removing the active supervisor engine from a switch, multicast and unicast packet loss occur (for 60 seconds) until route convergence completes.

Workaround: None. CSCun97605

Open Caveats for Cisco IOS Release 15.1(2)SG3

This section lists the open caveats for Cisco IOS Release 15.1(2)SG3:

  • VTP databases do not propagate through promiscuous trunk ports. If only promiscuous trunks are configured, you will not see the VLAN updates on the other switches in the VTP domain.

Workaround: Configure an ISL/dot1q trunk port. CSCsu43445

  • If you simultaneously apply a service-policy to a port in the output direction and a service-policy to a vlan-range under that port in the output direction, the class-map hit counters in the output of the
    show policy-map interface command are wrong.

Workaround: None.

The queue transmit counters as well as the policing statistics (if any) are correct. CSCsz20149

  • When you run Cisco IOS Release 12.2(53)SG1, 12.2(50)SG6, or later releases and configure switchport block multicast on a switch, Layer 2 multicast is not blocked. IPv4 and IPV6 unknown multicast traffic is blocked.

Prior to Cisco IOS Release 12.2(53)SG1 and 12.2(50)SG6, the switchport block multicast command blocks IP Multicast, Layer 2 multicast, and broadcast traffic. CSCta61825

Workaround: None CSCtb30327

  • When you configure open authentication and perform SSO, the spanning tree state and MAC address are not synchronized to the new standby supervisor engine. This behavior interrupts traffic only after the second switchover because the new standby supervisor engine possesses the wrong state after the initial switchover and the second switchover starts the port in the blocking state.

Workaround: Enter shut and no shut on the port to synchronize the STP state. CSCtf52437

  • A device in a Guest VLAN that is connected behind a phone capable of 2nd-port-TLV, experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.

Workaround: None. CSCto46018

  • If you reboot a switch, the configured value of the interface MTU size for the elements of the port channel interface does not work for IPv6 traffic.

Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.

CSCto27085

  • When you have two Layer 3 CE-facing interfaces, each connected to a CE to split WCCP between the CEs, and you move a WCCP service (such as 60 (ftp-native)) from one interface to the other, the target interface fails to completely transfer the service from the old to the new CE.

Workaround: Shut down the CE-facing interface. After all of the mask-value entries point to the target CE, unshut the CE-facing interface. CSCtl09941

  • If burst is not explicitly configured for a single rate policer, the show policy-map command displays an incorrect burst value.

Workaround: Enter the show policy-map interface command to find the actual burst value programmed. CSCsi71036

  • When you enter the show policy-map vlan vlan command, unconditional marking actions that are configured on the VLAN are not shown.

Workaround: None.

If you enter the show policy-map name, however, the unconditional marking actions appear. CSCsi94144

  • If an EtherChannel is a member of a FlexLink pair, then static MAC addresses configured on the EtherChannel are not moved to the alternate port when the EtherChannel fails (FlexLink failure).

Workaround: None. CSCsq99468

  • When a CFM Inward Facing MEP (IFM) is configured on a VLAN that is not allocated on a switch port that is DOWN, the show ethernet cfm maintenance-points local command displays the IFM CC Status as inactive. When you allocate the VLAN, the CC-status remains inactive.

You only see this behavior if you initially did not allocate a VLAN before you configure the IFM, and then later allocate the same VLAN.

Workaround: Unconfigure, and then reconfigure the IFM on the port.

  • Before large PACLs are fully loaded in hardware, you might observe a false completion messages like the following:
Dec 1 18:44:59.926: %C4K_COMMONHWACLMAN-4-HWPROGSUCCESS: Input Security: pacl - now fully loaded in hardware *Dec 1 18:44:59.926: %C4K_COMMONHWACLMAN-4-ALLACLINHW: All configured ACLs now fully loaded in hardware - hardware switching / QoS restored.
 

Workaround: No functional impact.

You must wait for the ACLs to be programmed before performing other TCAM related changes. CSCtd57063

  • WCCP service is not reacquired when a service group with a multicast group address is unconfigured, and then reconfigured.

Workaround: Configure IP multicast routing globally and establish IP PIM sparse dense mode on the CE-facing interface. CSCtl97692

  • When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the header is computed for DOT1X/RADIUS accounting messages.

A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2 uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting message, and the client marks the server as unresponsive.

Workaround: None. You must disable 802.1X accounting. CSCts26844

  • When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a flow.

Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.

Workaround: None. CSCts20229

  • When a switchover is created on the Mediatrace responder, the dynamic access list created for a monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic access lists after the switchover, the old ones remain in the configuration.

Stale dynamic access lists force the system to monitor unwanted traffic.

Workarounds:

If the switchover is scheduled, remove the scheduled session on the initiator. Reschedule the session after the new active supervisor engine boots on the responder.

If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots, manually delete the stale dynamic access lists. CSCty75070

  • When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps, ciscoBfdSessUp and ciscoBfdSessDown, are not generated.

Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration command. CSCtx51561

  • When you transfer a startup-config to the switch directly without entering write mem, and the startup-config contains the hw-module uplink shared-backplane command, the four ports on a Supervisor Engine 6-E are not activated in subsequent reloads. The second port of each supervisor engine remains inactive.

Workaround: Configure hw-module uplink shared-backplane from the console or vty, and enter write mem. CSCtx43568

  • During either a system- or user-initiated reload operation, the following message is observed when the system shuts down:
HARDWARE WATCHDOG
 

This message is not observed during a system bootup.

Workaround: None required. This message is information only. CSCtz15738

  • Configuring an interface as unidirectional with the unidirectional send-only | receive-only command still allows an interface to send (configured as Send-only Unidirection Ethernet mode) or receive (configured as Receive-only Unidirection Ethernet mode) packets in a bidirectional mode.

Workaround: None. CSCui10480

Resolved Caveats in Cisco IOS Release 15.1(2)SG3

This section lists the resolved caveats in Cisco Release 15.1(2)SG3:

  • On systems performing multicast routing, a brief increase in CPU consumption occurs every few minutes. In large-scale environments, this CPU increase is more noticeable.

Workaround: None. CSCub44553

  • SNMP may time out and produce CPUHOG messages when lldpXMedMIB is polled.

Workaround: CSCuh88726

  • A port configured for webauth is not programmed with the default or fallback ACL when sessions enter the INIT state.

Workaround: None. CSCuj71597

  • When a device authenticates with dot1x after authenticating with MAB, any policies applied by MAB remain in place.

Wokarounds:

Ensure that the dot1x supplicant always authenticates before MAB.

Create MAB policies for dot1x hosts that do not supply a URL redirect. CSCui79988

Open Caveats for Cisco IOS Release 15.1(2)SG2

This section lists the open caveats for Cisco IOS Release 15.1(2)SG2:

  • VTP databases do not propagate through promiscuous trunk ports. If only promiscuous trunks are configured, you will not see the VLAN updates on the other switches in the VTP domain.

Workaround: Configure an ISL/dot1q trunk port. CSCsu43445

  • If you simultaneously apply a service-policy to a port in the output direction and a service-policy to a vlan-range under that port in the output direction, the class-map hit counters in the output of the
    show policy-map interface command are wrong.

Workaround: None.

The queue transmit counters as well as the policing statistics (if any) are correct. CSCsz20149

  • When you run Cisco IOS Release 12.2(53)SG1, 12.2(50)SG6, or later releases and configure switchport block multicast on a switch, Layer 2 multicast is not blocked. IPv4 and IPV6 unknown multicast traffic is blocked.

Prior to Cisco IOS Release 12.2(53)SG1 and 12.2(50)SG6, the switchport block multicast command blocks IP Multicast, Layer 2 multicast, and broadcast traffic. CSCta61825

Workaround: None CSCtb30327

  • When you configure open authentication and perform SSO, the spanning tree state and MAC address are not synchronized to the new standby supervisor engine. This behavior interrupts traffic only after the second switchover because the new standby supervisor engine possesses the wrong state after the initial switchover and the second switchover starts the port in the blocking state.

  • A device in a Guest VLAN that is connected behind a phone capable of 2nd-port-TLV, experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.

Workaround: None. CSCto46018

  • If you reboot a switch, the configured value of the interface MTU size for the elements of the port channel interface does not work for IPv6 traffic.

Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.

CSCto27085

  • When you have two Layer 3 CE-facing interfaces, each connected to a CE to split WCCP between the CEs, and you move a WCCP service (such as 60 (ftp-native)) from one interface to the other, the target interface fails to completely transfer the service from the old to the new CE.

Workaround: Shut down the CE-facing interface. After all of the mask-value entries point to the target CE, unshut the CE-facing interface. CSCtl09941

  • If burst is not explicitly configured for a single rate policer, the show policy-map command displays an incorrect burst value.

Workaround: Enter the show policy-map interface command to find the actual burst value programmed. CSCsi71036

  • When you enter the show policy-map vlan vlan command, unconditional marking actions that are configured on the VLAN are not shown.

Workaround: None.

If you enter the show policy-map name, however, the unconditional marking actions appear. CSCsi94144

  • If an EtherChannel is a member of a FlexLink pair, then static MAC addresses configured on the EtherChannel are not moved to the alternate port when the EtherChannel fails (FlexLink failure).

Workaround: None. CSCsq99468

  • When a CFM Inward Facing MEP (IFM) is configured on a VLAN that is not allocated on a switch port that is DOWN, the show ethernet cfm maintenance-points local command displays the IFM CC Status as inactive. When you allocate the VLAN, the CC-status remains inactive.

You only see this behavior if you initially did not allocate a VLAN before you configure the IFM, and then later allocate the same VLAN.

Workaround: Unconfigure, and then reconfigure the IFM on the port.

  • Before large PACLs are fully loaded in hardware, you might observe a false completion messages like the following:
Dec 1 18:44:59.926: %C4K_COMMONHWACLMAN-4-HWPROGSUCCESS: Input Security: pacl - now fully loaded in hardware *Dec 1 18:44:59.926: %C4K_COMMONHWACLMAN-4-ALLACLINHW: All configured ACLs now fully loaded in hardware - hardware switching / QoS restored.
 

Workaround: No functional impact.

You must wait for the ACLs to be programmed before performing other TCAM related changes. CSCtd57063

  • WCCP service is not reacquired when a service group with a multicast group address is unconfigured, and then reconfigured.

Workaround: Configure IP multicast routing globally and establish IP PIM sparse dense mode on the CE-facing interface. CSCtl97692

  • When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the header is computed for DOT1X/RADIUS accounting messages.

A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2 uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting message, and the client marks the server as unresponsive.

Workaround: None. You must disable 802.1X accounting. CSCts26844

  • When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a flow.

Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.

Workaround: None. CSCts20229

  • When a switchover is created on the Mediatrace responder, the dynamic access list created for a monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic access lists after the switchover, the old ones remain in the configuration.

Stale dynamic access lists force the system to monitor unwanted traffic.

Workarounds:

If the switchover is scheduled, remove the scheduled session on the initiator. Reschedule the session after the new active supervisor engine boots on the responder.

If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots, manually delete the stale dynamic access lists. CSCty75070

  • When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps, ciscoBfdSessUp and ciscoBfdSessDown, are not generated.

Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration command. CSCtx51561

  • When you transfer a startup-config to the switch directly without entering write mem, and the startup-config contains the hw-module uplink shared-backplane command, the four ports on a Supervisor Engine 6-E are not activated in subsequent reloads. The second port of each supervisor engine remains inactive.

Workaround: Configure hw-module uplink shared-backplane from the console or vty, and enter write mem. CSCtx43568

  • During either a system- or user-initiated reload operation, the following message is observed when the system shuts down:
HARDWARE WATCHDOG
 

This message is not observed during a system bootup.

Workaround: None required. This message is information only. CSCtz15738

  • On systems performing multicast routing, a brief increase in CPU consumption occurs every few minutes. In large-scale environments, this CPU increase is more noticeable.

Workaround: None. CSCub44553

  • Configuring an interface as unidirectional with the unidirectional send-only | receive-only command still allows an interface to send (configured as Send-only Unidirection Ethernet mode) or receive (configured as Receive-only Unidirection Ethernet mode) packets in a bidirectional mode.

Workaround: None. CSCui10480

  • SNMP may time out and produce CPUHOG messages when lldpXMedMIB is polled.

Workaround: CSCuh88726

  • A port configured for webauth is not programmed with the default or fallback ACL when sessions enter the INIT state.

Workaround: None. CSCuj71597

  • When a device authenticates with dot1x after authenticating with MAB, any policies applied by MAB remain in place.

Wokarounds:

Ensure that the dot1x supplicant always authenticates before MAB.

Create MAB policies for dot1x hosts that do not supply a URL redirect. CSCui79988

Resolved Caveats in Cisco IOS Release 15.1(2)SG2

This section lists the resolved caveats in Cisco Release 15.1(2)SG2:

  • A GLC-GE-100FX pluggable may not operate when used in WS-X4624-SFP-E, WS-X4640-CSFP-E or WS-X4612-SFP-E modules.

Workaround: None CSCui23911

  • The switch may reload unexpectedly or become inaccessible when the integrated web server is used, either through direct web access to the switch, or indirectly through the webauth feature.

Workaround: Enter either the no ip http server or the no ip http secure-server command. This disables the http/s server. CSCui14525

Open Caveats for Cisco IOS Release 15.1(2)SG1

This section lists the open caveats for Cisco IOS Release 15.1(2)SG1:

  • VTP databases do not propagate through promiscuous trunk ports. If only promiscuous trunks are configured, you will not see the VLAN updates on the other switches in the VTP domain.

Workaround: Configure an ISL/dot1q trunk port. CSCsu43445

  • If you simultaneously apply a service-policy to a port in the output direction and a service-policy to a vlan-range under that port in the output direction, the class-map hit counters in the output of the
    show policy-map interface command are wrong.

Workaround: None.

The queue transmit counters as well as the policing statistics (if any) are correct. CSCsz20149

  • When you run Cisco IOS Release 12.2(53)SG1, 12.2(50)SG6, or later releases and configure switchport block multicast on a switch, Layer 2 multicast is not blocked. IPv4 and IPV6 unknown multicast traffic is blocked.

Prior to Cisco IOS Release 12.2(53)SG1 and 12.2(50)SG6, the switchport block multicast command blocks IP Multicast, Layer 2 multicast, and broadcast traffic. CSCta61825

Workaround: None CSCtb30327

  • When you configure open authentication and perform SSO, the spanning tree state and MAC address are not synchronized to the new standby supervisor engine. This behavior interrupts traffic only after the second switchover because the new standby supervisor engine possesses the wrong state after the initial switchover and the second switchover starts the port in the blocking state.

Workaround: Enter shut and no shut on the port to synchronize the STP state. CSCtf52437

  • A device in a Guest VLAN that is connected behind a phone capable of 2nd-port-TLV, experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.

Workaround: None. CSCto46018

  • If you reboot a switch, the configured value of the interface MTU size for the elements of the port channel interface does not work for IPv6 traffic.

Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.

CSCto27085

  • When you have two Layer 3 CE-facing interfaces, each connected to a CE to split WCCP between the CEs, and you move a WCCP service (such as 60 (ftp-native)) from one interface to the other, the target interface fails to completely transfer the service from the old to the new CE.

Resolved Caveats in Cisco IOS Release 15.1(2)SG1

This section lists the resolved caveats in Cisco Release 15.1(2)SG1:

  • With IGMP snooping enabled, multicast traffic received through a tunnel interface is not forwarded through the Outgoing Interface List.

Workaround: Disable IGMP snooping. CSCuc65538

  • When MLD snooping is enabled, control-plane policing on IPv6 ND packets stops working. This does not impact other control packets.

Workaround: None. CSCua89658

  • When a port connected to a CDP, DHCP, or LLDP speaker goes down, a small memory leak occurs (typically less than 300 bytes).

Workaround: Disable these protocols on interfaces that might flap frequently. CSCub85948

  • If REP is configured on a dot1q trunk and the native VLAN is administratively set to something other then the default, REP packets are not sent on the native VLAN

Workaround: Retain the trunk native VLAN as 1. CSCud05521

  • When a session is neither authenticated nor granted fallback authorization (e.g. by entering guest-vlan or auth-fail-vlan) in multi-auth mode, unauthenticated sessions remain indefinitely and are not cleared by the system.

Workaround: Clear sessions manually with the clear authentication sessions command. CSCtg15739

  • When a switch receives a change of auth(CoA) for a port, policies already applied to that port are not cleared.

Workaround: Send any policy with the CoA from the RADIUS server. CSCue62019

  • If URL redirect installed as part of authorization and either of the following occurs, memory will be leaked:

a fast stream of traffic matches the URL redirect ACL as IPDT clears an address,

a traffic stream matches the URL redirect ACL and no URL redirect policy is installed for that IP address,

If this occurs repeatedly, IPDT and other control packet processing ultimately ceases.

Workaround: If this behavior completely fills the CPU buffer, the switch must be reloaded. However, the frequency of encountering a stuck queue can be reduced to nearly zero by modifying the URL redirect ACL to permit only 80/443 traffic. CSCug56646

  • If a dACL name is too long (about 24 characters, depending on the interface where it is applied), the ACL will be incorrectly shared over multiple ports.

Workaround: Shorten the dACL name. CSCug78653

  • A switch running IOS Release 15.1(2)SG may crash during CPU packet switching with the following crash file vector:
========= Context ======================
pc=12EC6638 lr=128BFDD0 msr=02029230 vector=00000D00 >>>> D00

Resolved Caveats in Cisco IOS Release 15.1(2)SG

This section lists the resolved caveats in Cisco Release 15.1(2)SG:

  • Following an upgrade to IOS Release XE 3.3.1SG, the following error messages might display for switches with PWR-C45-4200ACV power supplies:
%C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED: Insufficient power supplies present for specified config
 
%C4K_CHASSIS-3-MIXINVOLTAGEDETECTED: Power supplies in the chassis are receiving different voltage inputs
 
%C4K_CHASSIS-3-MIXINPOWERDETECTED: Power supplies in the chassis are of different types (AC/DC) or wattage
 

Use the show power command to determine whether 220V inputs are incorrectly detected as “off” or 110V.

Workaround: Unseat or reseat the impacted power supply and turn on the input power. CSCuc50555.

  • A peer policy is not updated after reauthentication if the policy is changed on the AS beforehand. After reauthentication, the original peer policy is retained.

Workaround: Enter shut and no shut on the port. CSCts29515

  • The Cisco IOS Software implementation of the virtual routing and forwarding (VRF) aware network address translation (NAT) feature contains a vulnerability when translating IP packets that could allow an unauthenticated, remote attacker to cause a denial of service (Do) condition.
