Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.3.2XO

Current release: IOS XE 3.3.2XO—August 20, 2014

Prior release: IOS XE 3.3.1XO, IOS XE 3.3.0XO—August 14, 2013

This release note describes the features, modifications, and caveats for the Cisco IOS XE 3.3.xXO software on the Catalyst 4500E series switch with Supervisor Engine 8-E.

The new Cisco® Catalyst® 4500E Supervisor Engine 8-E extends one policy, one management, one network to the world's most widely deployed modular access switch. This brings convergence of wired and wireless (not available in the first release of convergence, IOS XE 3.3.0XO in networks on a single platform while providing unprecedented investment protection. It ushers in a new converged architecture that is simple, resilient, and secure.

The Cisco Catalyst 4500E Switch with Supervisor Engine 8-E is an extremely scalable and feature-rich modular access platform built to meet current and future network demand, and including gigabit desktop:

Converged Access

  • Hardware-readiness for built-in wireless controller with single software image for wired and wireless infrastructure
  • Hardware-readiness for delivery of up to 928 Gbps system bandwidth and nonblocking 48 Gbps per slot
  • Support for up to 20 G wireless throughput, 50 access points, and 2000 wireless clients on a single system and 250 access points and 4000 clients for multiswitch controllerless deployment
  • Eight nonblocking 10 Gigabit Ethernet (Small Form-Factor Pluggable Plus [SFP+]) future-proofed uplinks with field-programmable gate array (FPGA) devices to support next-generation protocols
  • Ability of 4500E chassis with Supervisor Engine 8-E to scale up to 384 Gigabit copper ports, 200 Gigabit fiber ports, or 104 10 Gigabit ports in non-VSS mode

Infrastructure Services

  • Maximum resiliency with redundant components, Nonstop Forwarding/Stateful Switchover (NSF/SSO)
  • Network virtualization through Multi-Virtual Route Forwarding (VRF) and Easy Virtual Networking (EVN) technology for Layer 3 segmentation
  • Power over Ethernet Plus (PoE+; 30 W) and Cisco Universal PoE (UPOE; 60 W) capabilities on all line-card slots

Investment Protection and Reduced Total Cost of Ownership

  • Full backward compatibility with 6-, 24-, and 48-Gbps line cards with no performance degradation
  • Compatibility with all shipping Cisco Catalyst 4500 chassis, line cards, and power supplies, thus providing full investment protection

Cisco Services

  • Optimized application performance through deep visibility with flexible NetFlow (FNF), supporting rich Layer 2, 3, and 4 information (MAC, VLAN, and TCP flags) and synthetic traffic with IP service-level agreements
  • Medianet capabilities for video quality of service (QoS), monitoring, and security

Support for Cisco IOS XE Release 3.3.0XO follows the standard Cisco Systems® support policy, available at

Cisco IOS Software Packaging

The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing.

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).

The LAN Base image complements the existing IP Base and Enterprise Services images. It is 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.

Cisco IOS XE Release Strategy

Sup8-E is introduced with Cisco IOS Release XE 3.3.0XO, which has feature parity with Release XE 3.3.0SG. Sup8-E support will be integrated into XE 3.6.0E, which will be an extended maintenance release.


NoteSup8-E is not supported on Release XE 3.3.nSG, XE 3.4.nSG, or XE 3.5.0E.

Limitations and Restrictions

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

  • For the 10-slot chassis, (C4510R+E), slot 10 can only support 47xx linecards; older 46xx are not supported.
  • Starting with Release IOS XE 3.3.0SG, the seven RP restriction was removed.
  • More than 16K QoS policies can be configured in software. Only the first 16K are installed in hardware.
  • Adjacency learning (through ARP response frames) is restricted to roughly 1000 new adjacencies per second, depending on CPU utilization. This should only impact large networks on the first bootup. After adjacencies are learned they are installed in hardware.
  • Multicast fastdrop entries are not created when RPF failure occurs with IPv6 multicast traffic. In a topology where reverse path check failure occurs with IPv6 multicast, this may cause high CPU utilization on the switch.
  • The SNMP ceImageFeature object returns a similar feature list for all the three license levels (LAN Base, IP Base, and EntServices). Although the activated feature set for a universal image varies based on the installed feature license, the value displayed by this object is fixed and is not based on the feature license level.
  • Standard TFTP implementation limits the maximum size of a file that can be transferred to 32 MB. If ROMMON is used to boot an IOS image that is larger than 32 MB, the TFTP transfer fails at the 65,xxx datagram.

TFTP numbers its datagrams with a 16 bit field, resulting in a maximum of 65,536 datagrams. Because each TFTP datagram is 512 bytes long, the maximum transferable file is 65536 x 512 = 32 MB. If both the TFTP client (ROMMON) and the TFTP server support block number wraparound, no size limitation exists.

Cisco has modified the TFTP client to support block number wraparound. So, if you encounter a transfer failure, use a TFTP server that supports TFTP block number wraparound. Because most implementations of TFTP support block number wraparound, updating the TFTP daemon should fix the issue.

  • 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>

  • When attaching a existing policy-map (that is already applied to a control-port) to another front-panel port, the following message displays:
The policymap <policy-map name> is already attached to control-plane and cannot be shared with other targets.
 

Workaround: Define a policy-map with a different name and then reattach. CSCti26172

  • If the number of unique FNF monitors attached to target exceeds 2048 (one per target), a switch responds slowly:

Workarounds:

Decrease the number of monitors.

Attach the same monitor to multiple targets. CSCti43798

  • ciscoFlashPartitionFileCount object returns an incorrect file count for bootflash:, usb0:, slot0:, slaveslot0:, slavebootflash:, and slaveusb0:.

Workaround: Use the dir device command (for example, dir bootflash:) to obtain the correct file count. CSCti74130

  • If multicast is configured and you make changes to the configuration, Traceback and CPUHOG messages are displayed if the following conditions exist:

At least 10K groups and roughly 20K mroutes exist.

IGMP joins with source traffic transit to all the multicast groups.

This is caused by the large number of updates generating SPI messages that must be processed by the CPU to ensure that the platform is updated with the changes in all the entries.

Workaround: None. CSCti20312

  • When attaching a existing policy-map (that is already applied to a control-port) to another front-panel port, following message displays:
The policymap <policy-map name> is already attached to control-plane and cannot be shared with other targets.
 

Workaround: Define a policy-map with a different name and then reattach. CSCti26172

  • With traffic running, entering clear ip mroute * with larger number of mroutes and over 6 OIFs will cause Malloc Fail messages to display.

You cannot clear a large number of mroutes at one time when traffic is still running.

Workaround: Do not clear all mroutes at once.

CSCtn06753

  • 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.

  • 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

  • When sup1 is in ROMMON and sup2 is in IOS, only sup2 can read the SEEPROM contents of the following chassis components:

chassis

fan-tray

clock-module

power-supplies

mux-buffer for each linecard slot

linecards

On sup1, when the sprom read .. command is entered for any of the above components, the SEEPROM contents are displayed as all “0”s.

When sup1 and sup2 are both in ROMMON (or both in IOS (SSO state)), they can read all SEEPROMs.

  • On the following linecard:

10/100/1000BaseT Premium POE E Series WS-X4648-RJ45V+E (JAE1348OY52)

the following restrictions apply:

Sub-interfaces are not supported.

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.

  • 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.

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

  • With IOS Release XE 3.3.0X0, ROMMON supports the Fa1 management interface at 10/100/1000Mbps full duplex mode only; 10/100/1000Mbps half-duplex is not supported. This prevents the FA1 management interface from operating when connected to a half-duplex hub.
  • Supervisor Engine 8-E does not support USB port.
  • Memory allocation failures can occur if more than 16K IPv6 multicast snooping entries are present.

Workaround: None. CSCuc77376

  • The following messages are seen during boot up after POST check.
Rommon reg: 0x00004F80
Reset2Reg: 0x00000F00

Caveats

Caveats describe unexpected behavior in Cisco IOS releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.


NoteFor the latest information on PSIRTS, refer to the Security Advisories on CCO at the following URL:

http://www.cisco.com/en/US/products/products_security_advisories_listing.html


Open Caveats for Cisco IOS XE Release 3.3.2XO

This section lists the open caveats for Cisco IOS XE Release 3.3.2XO:

  • 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 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

  • A device in a guest VLAN that is connected behind a phone that is capable of 2nd-port-notification 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

  • 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

  • IPv6 access-list counters do not increment when a policy-map associated with a class-map that matches a v6 ACL is applied to a physical interface and matching traffic is sent.
juhani07-a#sh ipv6 access-list v6acl
IPv6 access list v6acl
permit ipv6 host 2003::2 any (1000 matches) sequence 10 --- only 1000 matched although 2000 matching pkts sent
permit ipv6 host 2004::2 any sequence 20
 

Workaround: None CSCug54690

  • If you configure a Qos srTCM policer with actions (traffic conform, traffic exceed, and traffic violated), the marking action for exceed traffic remains inactive.

Workaround: Configure a policer with only conform-action and exceed-action and not with violate-action. CSCug49778.

  • When a linecard is reset on a switch using multicast, a message like the following map appear:
PIM_REG_TUN-3-UNNUM_ERR: STANDBY
 

This error is informational only.

Workaround: None. CSCug19842

  • The match application name and collect application name commands appear available for flow record configuration when you use the ? help listings. However, the following configuration is otherwise unsupported: show flow monitor i monitor-name i cache displays the application name as “unknown;” and the application table is not exported. So, the application name field cannot be decoded when exported.

Workaround: Do not configure the application name field as a key or non-key field of a flow record.

CSCue47944

  • The IOS Supplicant fails authentication when using PEAPv1 or MSChap to ACS 5.

Workaround: Use PEAP-GTC or any other method. CSCud66899

  • Immediately following an SSO, the following error message may be logged by the new active route processor:
%MRIB_PROXY-2-MRIB_RP_FAILED_LC_PORT_OPEN: RP failed in opening linecard port info for distributed mode, slot = 3. MRIB updates will not be distributed to this LC.
 

The error message is information only.

Workaround: None. CSCuc72249

  • 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

  • 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.

The impact of stale dynamic access lists is 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

  • If you perform an OIR on a line card, several %C4K_RKNOVA-4-INVALIDTOKENEXPIRED messages appear in the logs.

Workaround: None. CSCtu37959

  • Dynamic buffer limiting might not function at queue limits less than or equal to 128.

Workaround: Increase the queue limit to at least 256. CSCto57602

  • 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

  • On second switchover, MKA sessions go down and never recover.

Workaround: Shut then no shut the interface.

Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000

  • On second switchover, MKA sessions go down and never recover.

Workaround: Shut then no shut the interface.

Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000

  • 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 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
 

CSCtl06706

  • The show ipv6 access-list command displays incorrect match counts when multicast traffic is matched to an IPv6 access list that is attached to an SVI.

Workaround: None. CSCth65129

  • On IOS Release 15.2(1)E, the DUT MAC learn rate (4700 MAC sec) is lower than the rate (8000 MAC/sec) on IOS Release 3.4.0SG. When the macro auto monitor command is disabled on IOS Release 15.2(1)E, the rate is 13800 MAC/sec.

Workaround: None. CSCui07503

  • When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Info provider) increases substantially. The time required for a full walk of an almost fully populated table is 68 minutes.

Workaround: None. CSCth42248

Resolved Caveats for Cisco IOS XE Release 3.3.2XO

This section lists the resolved caveats for Cisco IOS XE Release 3.3.2XO:

  • WS-X4248 or WS-X4548- PoE modules reset PoE causing all connected PDs to lose power precipitating an outage. The following error log is observed:

*Feb 4 10:05:46.648: %C4K_CHASSIS-5-PORTSPOERESTARTED: Poe restarted for interfaces on slot 5 (count=1)

Workaround: None. CSCun21714

  • If a GRE tunnel is configured with ip unnumbered and you write this configuration, after reloading the system, the FIA table is not reloaded (i.e., all packets for that tunnel are dropped under "UnconfiguredIpv4Fia").

Workaround: Unconfigure the reconfigure the ip unnumbered command. CSCtb14871

  • IP DHCP Snooping bindings fail on first attempt.

Workaround: Issue either sh run or write memory. CSCui35423

  • When Performance Monitor feature is configured with threshold-crossing-alarms, the SNMP query FlowMetrics,FlowMonitor,Alarm returns the wrong values. Note the following MIBs:
cfmConditionsProfile
cfmAlarmHistoryConditionsProfile
cfmFlowMetricConditionsProfile
cfmFlowMonitorConditionsProfile
 

Workaround None. CSCuj48676

  • When you connect GLC-GE-100FX in WS-X4624-SFP-E, WS-X4640-CSFP-E or WS-X4612-SFP-E, the link doesn’t come up.

GLC-GE-100FX was tested with WS-X4624-SFP-E(HW 1.2(VID V02) and HW 2.0(VID V03)), the problem happened on GLC-GE-100FX V02 only. There was no problem with GLC-GE-100FX V01.

Workaround: None. CSCui23911

  • “ffm” progressively takes up more memory while free memory depletes by a similar amount.

This issue is triggered by one of the following:

consistent rapid flapping of mroute(s)

constant traffic toward a group on a VLAN where SVI is configured with PIM sparse mode but an RP is disallowed [for the group]

Workarounds:

For flapping mroutes, find the source of the flapping mroute and prevent it.

For a missing RP scenario, either turn off PIM on the VLAN or allow the multicast group associate with an RP. CSCul44174

  • If the session limit is exceeded for one flow, the show profile device command displays “empty:”
Newton# show profile flow

Workaround: None. CSCul98277

  • A switch crashes reliably when you issue the following command (under a VLAN) to enable unicast RPF:
ip verify unicast source reachable-via rx allow-default
 

Workaround: None. CSCum90900

  • After every reboot, the SNMPv2 configuration is lost; it is present in the startup-config but not in the running config. The config doesn't work after reboot:
snmp-server group S-GROUP-RO-GENERAL v2c read S-VIEW-GENERAL access ACL-4-mgmtVrf-SNMP-2-RO
 

With a different community or without snmp-server host 192.168.131.13 vrf mgmtVrf version 2c, the config line remains intact.

Workaround: Re-apply this configuration. CSCsh92025

  • A switch running cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin that points to an NTP server will observe forward clock shifting although NTP status shows that the sync is working.

Removing or adding the NTP configuration doesn't fix the issue.

Workaround: None. CSCui87789

  • A device running IOS-XE may reload unexpectedly.

Workaround: None. CSCul36468

  • If you configure dot1x for host-mode multi-host, phones that are in a voice VLAN do not acquire an IP address and are unable to be t registered to call manager

Workaround: Change to multi-domain or single host with CDP bypass (enable cdp/lldp on the switch). CSCuo79422

  • A switch crashes with Critical software exception during config push as 'Critical software exception'

Workload: None. CSCup39712

  • During an HA setup, the active supervisor engine reload does not complete within the allocated time and the following error message is displayed
%C4K_CHASSIS-3-MODULEBRINGUPTIMEDOUT: Module 2 software bring up did not complete within allocated time

Workaround: None. CSCuq17614

  • High CPU is observed when sending multicast traffic provided the switch is directly connected to the source and PIM SSM is configured but no receiver exists.

Workaround: Configure control plane policy to deny Multicast SSM traffic hitting CPU.

CSCub10733

  • Non-interested multicast traffic for PIM SM is punted to CPU after an IOS upgrade to IOS 15.1(2)SG.

Workarounds:

1. Apply ACL on ingress interface deny the non-interested PIM SM multicast stream:

enderman# show ip access-lists TAC
Extended IP access list TAC
10 deny ip host 10.1.1.3 host 239.1.1.5 (40 estimate matches)
20 permit ip any any (42 estimate matches)

 

2. Have a dummy loopback interface enabled with PIM-SM. Configure ip igmp static-group x.x.x.x on this Loopback interface (where x.x.x.x is non-interested multicast group ip address). CSCui64652

  • When PIM is enabled on an SVI interface, multicast traffic is dropped in certain scenario where it requires Layer 2 switching (Router on which Multicast (*, G) or (S, G) entry is not present for Group).

Workaround: Disable PIM SSM on the interface. CSCum47920

  • High CPU is observed with multicast SSM traffic, when the Source is directly connect to the Router.

Moreover, mroute is improperly programmed on the switch, which is connected to multicast source.

CSCuo06555

  • Multicast (S,G) entries are not created on intermediate routers running in PIM Dense-mode.

Workaround: None. CSCuo47803

  • Non-interested multicast traffic only is punted to CPU after upgrading to IOS Release 151-2.SG

Workarounds

Apply ACL on ingress interface denying the non-interested multicast stream. Below is the example.

enderman# show ip access-lists TAC
Extended IP access list TAC
10 deny ip host 10.1.1.3 host 239.1.1.5 (40 estimate matches)
20 permit ip any any (42 estimate matches)
 

Use a dummy loopback interface enabled with PIM-SM. Configure ip igmp static-group x.x.x.x on this Loopback interface (where x.x.x.x is the non-interested multicast group ip address).

Open Caveats for Cisco IOS XE Release 3.3.1XO

This section lists the open caveats for Cisco IOS XE Release 3.3.0XO:

  • When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Info provider) increases substantially. The time required for a full walk of an almost fully populated table is 68 minutes.

Workaround: None. CSCth42248

  • The show ipv6 access-list command displays incorrect match counts when multicast traffic is matched to an IPv6 access list that is attached to an SVI.

Workaround: None. CSCth65129

  • 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
 

CSCtl06706

  • 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

  • Dynamic buffer limiting might not function at queue limits less than or equal to 128.

Workaround: Increase the queue limit to at least 256. CSCto57602

  • 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

  • A device in a guest VLAN that is connected behind a phone that is capable of 2nd-port-notification 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 perform an OIR on a line card, several %C4K_RKNOVA-4-INVALIDTOKENEXPIRED messages appear in the logs.

Workaround: None. CSCtu37959

  • 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.

The impact of stale dynamic access lists is 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

  • 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

  • Immediately following an SSO, the following error message may be logged by the new active route processor:
%MRIB_PROXY-2-MRIB_RP_FAILED_LC_PORT_OPEN: RP failed in opening linecard port info for distributed mode, slot = 3. MRIB updates will not be distributed to this LC.
 

The error message is information only.

Workaround: None. CSCuc72249

  • On IOS Release 15.2(1)E, the DUT MAC learn rate (4700 MAC sec) is lower than the rate (8000 MAC/sec) on IOS Release 3.4.0SG. When the macro auto monitor command is disabled on IOS Release 15.2(1)E, the rate is 13800 MAC/sec.

Workaround: None. CSCui07503

  • When a linecard is reset on a switch using multicast, a message like the following map appear:
PIM_REG_TUN-3-UNNUM_ERR: STANDBY
 

This error is informational only.

Workaround: None. CSCug19842

  • If you configure a Qos srTCM policer with actions (traffic conform, traffic exceed, and traffic violated), the marking action for exceed traffic remains inactive.

Workaround: Configure a policer with only conform-action and exceed-action and not with violate-action. CSCug49778.

  • The match application name and collect application name commands appear available for flow record configuration when you use the ? help listings. However, the following configuration is otherwise unsupported: show flow monitor i monitor-name i cache displays the application name as “unknown;” and the application table is not exported. So, the application name field cannot be decoded when exported.

Workaround: Do not configure the application name field as a key or non-key field of a flow record.

CSCue47944

  • IPv6 access-list counters do not increment when a policy-map associated with a class-map that matches a v6 ACL is applied to a physical interface and matching traffic is sent.
juhani07-a#sh ipv6 access-list v6acl
IPv6 access list v6acl
permit ipv6 host 2003::2 any (1000 matches) sequence 10 --- only 1000 matched although 2000 matching pkts sent
permit ipv6 host 2004::2 any sequence 20
 

Workaround: None CSCug54690

  • The IOS Supplicant fails authentication when using PEAPv1 or MSChap to ACS 5.

Workaround: Use PEAP-GTC or any other method. CSCud66899

  • On second switchover, MKA sessions go down and never recover.

Workaround: Shut then no shut the interface.

Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000

  • After switchover, the following message may appear:
*Jul 23 14:20:22.196: %SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "RF Slave Main Thread", ipl= 0, pid= 14
 

There is no functional impact when this message is printed.

Workaround: None. CSCui25812

  • Only non-interested multicast traffic is punted to the CPU after an IOS upgrade to 151-2.SG.

Workarounds:

Apply ACL on an ingress interface to deny the non-interested multicast stream, as follows:

enderman# sh ip access-lists TAC
Extended IP access list TAC
10 deny ip host 10.1.1.3 host 239.1.1.5 (40 estimate matches)
20 permit ip any any (42 estimate matches)
 

Enable PIM-SM on a dummy loopback interface by configuring ip igmp static-group x.x.x.x (where x.x.x.x is the non-interested multicast group IP address)

CSCui64652

  • A device in a guest VLAN that is connected behind a phone that is capable of 2nd-port-notification 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

  • 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

Resolved Caveats for Cisco IOS XE Release 3.3.1XO

This section lists the resolved caveats for Cisco IOS XE Release 3.3.1XO:

  • If you are running "cat4500e-universalk9.SPA.03.05.00.E.152-1.E.bin c3750e-universalk9-mz.152-1.E.bin" SNMP could cause the device to suddenly crash:

When polling the device to get an instance for CafSessionEntry object, as follows:

Object cafSessionEntry
OID 1.3.6.1.4.1.9.9.656.1.4.1.1
 

In redundant scenarios, switchover occurs repeatedly.

Workaround: Create SNMP view and exclude the OID, as follows:

config t
snmp-server view cutdown iso included
snmp-server view cutdown 1.3.6.1.4.1.9.9.656.1.4.1.1 excluded
snmp-server community <name> view cutdown RO
snmp-server community <name> view cutdown RW
 

CSCul24080

  • If you are using dot1x and dACL and the same dACL is applied on multiple ports, one device per port, so device tracking is not substituting "ANY" with the "IP address in dACL," the dACL is either not applied on the port or deactivated on the ports on which it was previously applied.

The following error message is observed in the output of the debug ip admission api command:

002864: *Oct 17 08:39:11.698: ip_admission_api:GaliosEpm_hostPolicyUpdate: Adding 1 ACEs to ACL NACL_xACSACLx-IP-PERMIT_ALL_TRAFFIC-5165e13c failed!
 

Workaround: Assign different names for the ACLs on each port. CSCuj88557

  • When the same ACL is installed on two ports, ACS-configured Dynamic ACLs are neither applied nor removed from the hardware.

Workaround: None. CSCuj99722

  • While freeing routes on a device, a crash occurs if one of the following apply:

Configured tags (anywhere in topology) are received by a router operating with EIGRP Rel. 12 and later.

Query received for the route updated with tags.

Workaround: None. CSCue78975

  • On a switch running "ct5760-ipservicesk9.bin cat3k_caa-universalk9.bin cat4500e-universalk9.bin" configured with device-originated UDP services (includes but not limited to the features: TFTP, Energywise, DNS, and Cisco TrustSec, UDP based entries are not deleted from the flowmgr table resulting in a crash or poor system response, and CPU hog messages display.

To confirm that you are affected by this bug, issue the following:

Router# config terminal
service internal
end
Router# show flowmgr
 

The output lists the entries in the flowmgr table. When this issue is seen, the flowmgr entries continue to increment (i.e., flow details are still present even after the connection is closed.)

Workaround: None.

Reloading is required to clean up the flowmgr entries that are present in the flowmgr table. Replace tftp with ftp, if possible. CSCuh09324

  • Removing the default configuration resulting from the monitor session id filter packet-type good rx command from an active SPAN session triggers HSRP and EIGRP flaps making the switch unreachable from directly connected peers.

Workaround: Restore the default config of the monitor session id filter packet-type good rx command and issue shut then no shut on the 'err-disabled' ports. CSCui56867

  • A vulnerability in the implementation of the IP version 6 (IPv6) protocol stack in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause I/O memory depletion on an affected device that has IPv6 enabled. The vulnerability is triggered when an affected device processes a malformed IPv6 packet.

Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.

This advisory is available at the following link:

  • A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of the affected device that would lead to a denial of service (DoS) condition.

The vulnerability is due to how an affected device processes certain malformed IKEv2 packets. An attacker could exploit this vulnerability by sending malformed IKEv2 packets to an affected device to be processed. An exploit could allow the attacker to cause a reload of the affected device that would lead to a DoS condition.

Although IKEv2 is automatically enabled on a Cisco IOS Software and Cisco IOS XE Software devices when the Internet Security Association and Key Management Protocol (ISAKMP) is enabled, the vulnerability can be triggered only by sending a malformed IKEv2 packet.

Only IKEv2 packets can trigger this vulnerability.

Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.

Workaround: See published Cisco Security Advisory CSCui88426

  • A switch may leak memory in the I/O pool due to mDNS traffic. The pool in which the leak is seen is dependent on the size of the incoming packet

Alternatively, the input queue on the interface may be stuck at the maximum size and starts to drop further traffic. This can cause pings to fail and protocols like HSRP,OSPF etc to not establish.

This symptom occurs when mDNS traffic is sent to the switch.

Workaround: Apply an ACL to the inbound interface. This will drop the traffic and buffers will not leak. CSCuj58950

  • Multiple iterations of the show platform cpu packet driver command cause ARP, IGMP and other control protocols to stop processing and displays the following:

  • When you issue either the device-sensor accounting or access-session accounting attributes command, subscriber accounting is not propagated from the switch to the ISE.

Workaround: Don’t enable the device-sensor accounting. :CSCuj56845

  • Frequent polling of CPU-PROCESS-MIB may cause a switch to unexpectedly reload.

Workaround: Apply the following SNMP view to restrict polling of the MIB:

snmp-server view restrict iso included
snmp-server view restrict ciscoProcessMIB excluded
snmp-server community mycommunity view restrict
 

CSCug65204

  • When authentication control direction in and mab are configured together on the interface, a MAB session is not triggered.

Workaround: Use either the authentication control-direction both or authentication open command. CSCuo50590

  • Very rarely, the following error message displays on the active supervisor engine before the standby supervisor engine achieves standby hot in SSO operating mode:
C4K_RADIANMAN-2-SWITCHLINKBRINGUPFAILED: Stub internal link bringup failed
 

This error does not impact functionality. However, the uplink ports of the standby supervisor engine loses functionality if the standby supervisor engine becomes the active supervisor engine.

Workaround: Reinsert the standby supervisor engine. CSCui25419

  • 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.

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

  • 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

  • Immediately following an SSO, the following error message may be logged by the new active route processor:
%MRIB_PROXY-2-MRIB_RP_FAILED_LC_PORT_OPEN: RP failed in opening linecard port info for distributed mode, slot = 3. MRIB updates will not be distributed to this LC.
 

The error message is information only.

Workaround: None. CSCuc72249

  • On IOS Release 15.2(1)E, the DUT MAC learn rate (4700 MAC sec) is lower than the rate (8000 MAC/sec) on IOS Release 3.4.0SG. When the macro auto monitor command is disabled on IOS Release 15.2(1)E, the rate is 13800 MAC/sec.

Workaround: None. CSCui07503

  • When a linecard is reset on a switch using multicast, a message like the following map appear:
PIM_REG_TUN-3-UNNUM_ERR: STANDBY
 

This error is informational only.

Workaround: None. CSCug19842

  • If you configure a Qos srTCM policer with actions (traffic conform, traffic exceed, and traffic violated), the marking action for exceed traffic remains inactive.

Workaround: Configure a policer with only conform-action and exceed-action and not with violate-action. CSCug49778.

  • The match application name and collect application name commands appear available for flow record configuration when you use the ? help listings. However, the following configuration is otherwise unsupported: show flow monitor i monitor-name i cache displays the application name as “unknown;” and the application table is not exported. So, the application name field cannot be decoded when exported.

Workaround: Do not configure the application name field as a key or non-key field of a flow record.

  • IPv6 access-list counters do not increment when a policy-map associated with a class-map that matches a v6 ACL is applied to a physical interface and matching traffic is sent.
juhani07-a#sh ipv6 access-list v6acl
IPv6 access list v6acl
permit ipv6 host 2003::2 any (1000 matches) sequence 10 --- only 1000 matched although 2000 matching pkts sent
permit ipv6 host 2004::2 any sequence 20
 

Workaround: None CSCug54690

  • The IOS Supplicant fails authentication when using PEAPv1 or MSChap to ACS 5.

Workaround: Use PEAP-GTC or any other method. CSCud66899

  • Very rarely, the following error message displays on the active supervisor engine before the standby supervisor engine achieves standby hot in SSO operating mode:
C4K_RADIANMAN-2-SWITCHLINKBRINGUPFAILED: Stub internal link bringup failed
 

This error does not impact functionality. However, the uplink ports of the standby supervisor engine loses functionality if the standby supervisor engine becomes the active supervisor engine.

Workaround: Reinsert the standby supervisor engine. CSCui25419

  • On second switchover, MKA sessions go down and never recover.

Workaround: Shut then no shut the interface.

Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000

  • After switchover, the following message may appear:
*Jul 23 14:20:22.196: %SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "RF Slave Main Thread", ipl= 0, pid= 14
 

There is no functional impact when this message is printed.

Workaround: None. CSCui25812

Resolved Caveats for Cisco IOS XE Release 3.3.0XO

This section lists the resolved caveats for Cisco IOS XE Release 3.3.0XO:

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

Workaround: Disable CDP on interfaces that may flap frequently. CSCub85948

  • When one interface is the control-plane, EPC does not work; you cannot start packet capture.

Workaround: None. CSCud78441

Troubleshooting

These sections provide troubleshooting guidelines for the Catalyst 4500 series switches running IOS supervisor engines:

  • Netbooting from ROMMON, page 39
  • Troubleshooting at the System Level, page 40
  • Troubleshooting Modules, page 40
  • Troubleshooting MIBs, page 40

Netbooting from ROMMON

Netbooting using a boot loader image is not supported. Instead, use one of the following options to boot an image:

1. Boot from an SD card by entering the following command:

rommon 1> boot slot0:<bootable_image>
 

2. Use ROMMON TFTP boot.

The ROMMON TFTP boot is very similar to the BOOTLDR TFTP boot, except that:

the BOOTLDR variable should not be set

the TFTP server must be accessible from the Ethernet management port on the supervisor engine.

To boot from ROMMON, perform the following tasks while in ROMMON mode:

a. Ensure that the Ethernet management port on the supervisor engine is physically connected to the network.

b. Verify that bootloader environment is not set by entering the unset bootldr command.

c. Set IP address of the Ethernet management port on the supervisor engine by entering the following command: set interface fa1 ip_address ip_mask

For example, to set the supervisor engine Ethernet port with an IP address 172.16.1.5 and IP mask 255.255.255.0, enter the following command:

rommon 2> set interface fa1 172.16.1.5 255.255.255.0
 

d. Set default gateway for the Ethernet management port on the supervisor engine by entering the following command: set ip route default gateway_ip_address . The default gateway should be directly connected to the supervisor engine Ethernet management port subnet.

e. Ping the TFTP server to ensure that there is connectivity to the server from the Ethernet management port on the supervisor engine by entering the following command: ping tftp_server_ip_address .

f. Once the ping is successful, boot the image from the TFTP server by entering the following command: boot tftp:// tftp_server_ip_address / image_path_and_file_name

For example, to boot the Cisco IOS XE image cat4500e-universalk9.03.01.00 .SG.150-1.XO.bin located on the TFTP server 172.16.1.8, enter the following command:

rommon 3> boot tftp://172.16.1.8/tftpboot/cat4500e-universalk9.03.01.00 .SG.150-1.XO.bin

Troubleshooting at the System Level

This section contains troubleshooting guidelines for system-level problems:

  • When the system is booting and running power-on diagnostics, do not reset the switch.
  • Ensure that you do not mix the serial and Ethernet cables plugged into the supervisor engine. The Fast Ethernet port (10/100 MGT) on the supervisor engine is inoperative. An Ethernet cable plugged into the Fast Ethernet port is active only in ROMMON mode.

Troubleshooting Modules

This section contains troubleshooting guidelines for modules:

  • When you hot insert a module into a chassis, always use the ejector levers on the front of the module to seat the backplane pins properly. Inserting a module without using the ejector levers might cause the supervisor engine to display incorrect messages about the module. For module installation instructions, refer to the Catalyst 4500 Series Module Installation Guide .
  • Whenever you connect an interface that has duplex set to autonegotiate to an end station or another networking device, ensure that the other device is configured for autonegotiation as well. If the other device is not set to autonegotiate, the port set to autonegotiate will remain in half-duplex mode, which can cause a duplex mismatch resulting in packet loss, late collisions, and line errors on the link.

Troubleshooting MIBs

For general information on MIBs, RMON groups, and traps, refer to the Cisco public MIB directory ( http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml ). For information on the specific MIBs supported by the Catalyst 4500 series switches, refer to the Catalyst 4000 MIB Support List located at ftp://ftp.cisco.com/pub/mibs/supportlists/cat4000/cat4000-supportlist.html.
