Cisco IOS Software Packaging

The Enterprise Services image supports all Cisco Catalyst 4500-X 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), Full OSPF, Full Enhanced Interior Gateway Routing Protocol (EIGRP) & Virtual Routing Forwarding (VRF-lite).

Starting with Cisco IOS Release XE 3.5.0E, support for policy-based routing (PBR) have been extended from Enterprise Services to IP Base, also OSPF Routed Access in IP Base now supports up to 1000 routes.

Cisco IOS XE Release Strategy

Customers with Catalyst 4500-X Series Switches who need the latest hardware and software features should migrate to Cisco IOS Release XE 3.5.0E.

IOS XE 3.4.xSG is a maintenance train supporting Sup7E, Sup7L-E and 4500-X.

Cisco IOS XE to Cisco IOS Version Number Mapping

As Table 7 shows, each version of Cisco IOS XE has an associated Cisco IOS version:

Table 7 Cisco IOS XE to Cisco IOS Version Number Mapping

Cisco IOS XE Version
Cisco IOS Version

03.3.0SG

15.1(1)SG

03.3.1SG

15.1(1)SG1

03.4.0SG

15.1(2)SG

03.5.0E

15.2(1)E

Upgrading the System Software

If you are upgrading to IOS XE Version 3.5.0E and are planning on using VSS, you must upgrade your ROMMON to IOS Version 15.0(1r)SG10. Else, leave the ROMMON at its default level.

Limitations and Restrictions

  • 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 (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>
 

CSCtg93278

  • When attaching an 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

  • 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.
  • Energywise WOL is not “waking up” a PC in hibernate or standby mode.

Workaround: None. CSCtr51014

  • When OSPFv3 LSA throttling is configured, rate limiting does not take effect for a few minutes.

WorkAround: None. CSCtw86319

  • 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 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 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

  • 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

  • Routed packets that are fragmented are not policed if the egress interface is on the VSS Standby switch. However, if the egress interface is on the VSS active switch, these packets are policed.

This applies to QoS policing only. QoS marking, shaping and sharing behave as expected.

Workaround: None. CSCub14402

  • 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

  • During VSS conversion, the switch intended as the Standby device may require up to 9 minutes to reach an SSO state. The boot up time depends on the configuration and on the number of line cards in the system.

Workaround: None. CSCua87538

  • An incorrect module number is displayed in the console messages during boot up of a Cat4500X VSS.
*Jul 18 12:36:11.138: %C4K_IOSMODPORTMAN-6-MODULEONLINE: Module 11 (WS-C4500X-32
S/N: JAE154503I8 Hw: 1.0) is online
 

Because the Catalyst 4500-X is a “fixed” configuration device, in a VSS, you would expect the two systems to be labeled 'Module 1' and 'Module 2.’ However, because of software implementation similarities with the modular Catalyst 4500E series switches, the Standby switch is labeled 'Module 11.’

Workaround: None. CSCub11632

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

Workaround: None. CSCuc77376

  • When an asymmetric virtual switch (i.e. a VSS comprising of chassis with different slot capacities) boots initially after conversion from standalone mode, the entPhysicalDescr object for the standby chassis does not hold the correct value. The entPhysicalDescr objects for both the active and standby chassis will match and hold the value for the active chassis.

After the running configuration is saved and a shelf reload occurs, this behavior is not observed - the entPhysicalDescr objects for both chassis accurately reflects the correct chassis types.

  • Beginning with IOS Release XE 3.5.0E, error messages that occur when a QoS policy is applied will no longer appear directly on the console when no logging console is configured. They will appear only when a logging method is active (e.g., logging buffered, logging console, …).

Workaround: None. CSCuf86375

  • Setting a cos value based on QoS group triggers the following error message in a VSS system
set action fail = 9
 

Workaround: None. QoS groups are not supported in VSS. CSCuc84739

  • Auto negotiation cannot be disabled on the Fa1 port. It must be set to auto/auto, or fixed speed with duplex auto.
  • 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.


Note For 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 3.5.3E

  • When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Information provider) increases substantially. The query time 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 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

  • 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

  • A device in a guest VLAN that is connected behind a phone 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 display flow statistics.

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

  • When MLD Snooping is disabled, a Catalyst 4500-X switch cannot maintain 6,000 MLD joins, causing traffic loss due to missing outgoing interfaces.

Workaround: Enable MLD snooping. CSCtx82176

  • When a Catalyst 4500-X uplink module is removed incorrectly, hardware forwarding tables are frozen, and baseboard ports remain connected for 20 to 25 seconds.

Workaround: Remove the Catalyst 4500-X module by first pressing the Ejector button for 10 seconds until the light turns green. CSCty67871

Caution: If you remove the module without following this procedure, the system always shuts down (or fails). Always use the Ejector button.

  • For the 10-Gigabit interface on a Catalyst 4500-X switch, link flaps are observed if the debounce interval is defined with the link debounce time command to within 1 second of the pulse interval.

For example, if the pulse interval is 250 ms and the debounce interval is 500 ms, then the delta is 250 ms and the debounce will be ineffective.

Workaround: Define a debounce interval that is at least 1 second greater than the incoming pulse interval. CSCtx75188

  • In a multichassis port channel on a VSS system with a very high number of link up and down events that occur within a second and typically causes an error-disable event, only the ports on the active switch are error-disabled due to flaps.

Workaround: None. CSCuc36612

  • If you enter the show spi-fc 12 command, a crash occurs.

Workaround: Use the show spi-fc all command to dump all SPI channel information. CSCuc81286

  • 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

  • Packets that are routed on the same Layer 3 interface (or SVI) that entered on are dropped if received on the VSS standby switch.

Workaround: None. CSCub63571

  • You can attach an input QoS policy to VSL member ports, but you cannot detach it. You only can configure VSL ports.

Workaround: Default the VSL member ports and detach the input QoS policy. CSCuc49150

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

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

  • 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

  • The POST results on the VSS standby switch displayed by the show diagnostic result module all detail command indicate module number 1 rather than 11. The module number is not interpreted by Cisco IOS.

Workaround: None. CSCuc73632

  • The following (information-only) error message and traceback may occur during MFIB-to-platform state updates for Bidirectional PIM (*,G/m) entries associated with Bidirectional PIM rendezvous points:
%SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "MFIB_mrib_read", ipl= 0, pid= 370
-Traceback= 1#f95b67f80cdf0886bbf15560d7553abc :152CC000+2699F4C :152CC000+269A310 :152CC000+1F1B55C :152CC000+38D5F4C :152CC000+2C25698 :152CC000+2C2EDF4 :152CC000+5F6F0B0 :152CC000+5F6F1A0 :152CC000+2C2F274 :152CC000+2C24AA4 :152CC000+119935C :152CC000+1D94244 :152CC000+119B070 :152CC000+119699C :152CC000+2C50D00 :152CC000+2B5901C
 

These messages are typically observed during SSO, bootup, or when a PIM-enabled interface undergoes a state transition on a switch containing Bidir PIM state entries.

Workaround: None. CSCud39208

  • Sometimes, after VSS comes up, the control links display different VSL links.

Workaround: Convert the VSS member switch to standalone and bring up VSS again. CSCug86547...Predator and K10

  • An IPv6 BFD session flaps if you configure a 100 * 3 timer value.

Workaround: Set the BFD timer and multiplier as 100 * 5. CSCuh35017

  • BFD supports 300ms and time values exceeding (100 * 3).

Workaround: None. CSCuh19345

  • Policer and Classification statistics do not increment during ISSU runversion when you downgrade from IOS Release XE 3.5.0E.

Workaround: This issue is transient. Policer and Classification statistics are available after ISSU completes. CSCuh90975

  • When a queuing policy is applied to a Layer 3 MEC member port, queuing statistics do not increment.

Workaround: None CSCuh76328

  • In a VSS (virtual switching system) setup, the show switch virtual link EXEC command displays VSL control link port numbers on different VSLs (virtual switching links) rather then displaying port numbers on the same link.

Workaround: Convert the VSS to a standalone setup. CSCug86547

  • A switch crashes when the you enter the show power inline module 1 and show power inline module 1 detail commands in two different telnet sessions and reset the linecard using a third telnet session.

Workaround: Reset the term length to 0 on the vty session. CSCuf08112

  • On configuring power inline consumption, the show power inline command might not display the values of the power consumed by the PD.

Workaround: Shut then no shut the interface. CSCue72897

  • The match application name and collect application name commands appear as available for flow record configuration (e.g., when using the ? help listings). However, this configuration is otherwise unsupported: the show flow monitor monitor-name cache command shows the application name as 'unknown,’ and the application table is not exported, so this 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

  • Occasionally, when the VSL goes down on a VSS with fast-hello based dual-active detection, the Layer 2 convergence time exceeds the Layer 2 convergence time observed with e-pagp based dual-active detection by 20ms.

However, the Layer 2 convergence time of the former stills meet the sub-second convergence criteria.

Open Caveats for Cisco IOS XE Release 3.5.2E

  • When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Information provider) increases substantially. The query time 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 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

  • 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

  • A device in a guest VLAN that is connected behind a phone 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 display flow statistics.

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

  • When MLD Snooping is disabled, a Catalyst 4500-X switch cannot maintain 6,000 MLD joins, causing traffic loss due to missing outgoing interfaces.

Workaround: Enable MLD snooping. CSCtx82176

  • When a Catalyst 4500-X uplink module is removed incorrectly, hardware forwarding tables are frozen, and baseboard ports remain connected for 20 to 25 seconds.

Workaround: Remove the Catalyst 4500-X module by first pressing the Ejector button for 10 seconds until the light turns green. CSCty67871

Caution: If you remove the module without following this procedure, the system always shuts down (or fails). Always use the Ejector button.

  • For the 10-Gigabit interface on a Catalyst 4500-X switch, link flaps are observed if the debounce interval is defined with the link debounce time command to within 1 second of the pulse interval.

For example, if the pulse interval is 250 ms and the debounce interval is 500 ms, then the delta is 250 ms and the debounce will be ineffective.

Workaround: Define a debounce interval that is at least 1 second greater than the incoming pulse interval. CSCtx75188

  • In a multichassis port channel on a VSS system with a very high number of link up and down events that occur within a second and typically causes an error-disable event, only the ports on the active switch are error-disabled due to flaps.

Workaround: None. CSCuc36612

  • If you enter the show spi-fc 12 command, a crash occurs.

Workaround: Use the show spi-fc all command to dump all SPI channel information. CSCuc81286

  • 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

  • Packets that are routed on the same Layer 3 interface (or SVI) that entered on are dropped if received on the VSS standby switch.

Workaround: None. CSCub63571

  • You can attach an input QoS policy to VSL member ports, but you cannot detach it. You only can configure VSL ports.

Workaround: Default the VSL member ports and detach the input QoS policy. CSCuc49150

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

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

  • 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

  • The POST results on the VSS standby switch displayed by the show diagnostic result module all detail command indicate module number 1 rather than 11. The module number is not interpreted by Cisco IOS.

Workaround: None. CSCuc73632

  • The following (information-only) error message and traceback may occur during MFIB-to-platform state updates for Bidirectional PIM (*,G/m) entries associated with Bidirectional PIM rendezvous points:

These messages are typically observed during SSO, bootup, or when a PIM-enabled interface undergoes a state transition on a switch containing Bidir PIM state entries.

Workaround: None. CSCud39208

  • Sometimes, after VSS comes up, the control links display different VSL links.

Workaround: Convert the VSS member switch to standalone and bring up VSS again. CSCug86547...Predator and K10

  • An IPv6 BFD session flaps if you configure a 100 * 3 timer value.

Workaround: Set the BFD timer and multiplier as 100 * 5. CSCuh35017

Workaround: None. CSCuh19345

  • Policer and Classification statistics do not increment during ISSU runversion when you downgrade from IOS Release XE 3.5.0E.

Workaround: This issue is transient. Policer and Classification statistics are available after ISSU completes. CSCuh90975

  • When a queuing policy is applied to a Layer 3 MEC member port, queuing statistics do not increment.

Workaround: None CSCuh76328

  • In a VSS (virtual switching system) setup, the show switch virtual link EXEC command displays VSL control link port numbers on different VSLs (virtual switching links) rather then displaying port numbers on the same link.

Workaround: Convert the VSS to a standalone setup. CSCug86547

  • A switch crashes when the you enter the show power inline module 1 and show power inline module 1 detail commands in two different telnet sessions and reset the linecard using a third telnet session.

Workaround: Reset the term length to 0 on the vty session. CSCuf08112

  • On configuring power inline consumption, the show power inline command might not display the values of the power consumed by the PD.

Workaround: Shut then no shut the interface. CSCue72897

  • The match application name and collect application name commands appear as available for flow record configuration (e.g., when using the ? help listings). However, this configuration is otherwise unsupported: the show flow monitor monitor-name cache command shows the application name as 'unknown,’ and the application table is not exported, so this 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

  • Occasionally, when the VSL goes down on a VSS with fast-hello based dual-active detection, the Layer 2 convergence time exceeds the Layer 2 convergence time observed with e-pagp based dual-active detection by 20ms.

However, the Layer 2 convergence time of the former stills meet the sub-second convergence criteria.

These messages does not impact ISSU processing.

These messages may be seen on both VSS and standalone topologies.

Workaround: None CSCue37937

  • While performing an ISSU upgrade from a prior release (like upgrading IOS Release XE 3.3.0SG (or 3.4.0SG) to 3.5.0E) the following message are displayed several times on the switch console:
%CTS-3-MSG_NOT_COMPATIBLE_WITH_PEER: STANDBY:Message 2 in component 3 is not compatible with the peer.
 

This behavior does not impact functionality.

Workaround: None. CSCuh47387

  • When a command's paginated output is sent into a pipe on a switch using VSS, console control is not returned.

Workarounds:

1. Use terminal length 0 to turn off pagination.

2. Use any key other than Enter or Space. CSCui44781

  • IPv6 Source Guard does not block packets from IP sources that are not in the binding table.

Workaround: None CSCug79180

  • UDE does not function at 1Gbps.

Workaround: None. CSCuj56314

  • If BFD sessions are hardware offloaded in a VSS, BFD sessions undergo re-negotiation after a VSS switchover.

Workaround: None. CSCug62308

  • If BFD is configured in a VSS, BFD sessions flap after a VSS switchover.

Workaround: Issue the bfd interval 999 min_rx 999 multiplier 6 command on the interface participating in the BFD session. CSCuh16490

  • After kron performs a write of the startup-config (e.g. 'write mem'), it is locked indefinitely (i.e., the startup-config and running-config are unavailable):
switch# show run
Unable to get configuration. Try again later.
 

Workaround; Reload the switch.

To avoid this condition, use EEM with the timer event to schedule the required task.

Resolved Caveats for Cisco IOS XE Release 3.5.1E

  • If login quiet-mode is configured, a switch resets when you enter the no login block-for command.

Workaround: None. CSCts80209

  • A Catalyst 4500-X switch might crash while running the Wireshark feature provided you do the following:

Step 1 Start “capture” with an IPv4, IPv6, or MAC filter (using the match keyword).

Step 2 Stop “capture and configure for a different filter.

Step 3 Re-start “capture.”


 

Workaround: Use an acl/class-map (in config mode) rather than the "monitor capture name match [ipv4 | ipv6 | mac] command. CSCuj23896

  • If you issue the show platform cpu packet driver command multiple times, ARP, IGMP and other control protocols cease processing and the following output displays:

  • When the same ACL is installed on two ports of a switch and a user is unauthenticated or logged out, the ACS-configured dynamic ACLs are not applied or deleted from the port.

Workaround: None CSCuj99722

  • A Dynamic ACL with a remark statement is not pushed from ISE to client and authorization either fails or is unauthorized.

Workaround: Remove the remark statement from the DACL. CSCuj35704

  • When you enable either the device-sensor accounting or the access-session accounting attributes command, the accounting request itself is not sent from the switch to the radius (ISE) Server.

Workaround: Do not enable device-sensor accounting.

The user accounting message will not carry the device-sensor attributes to the ISE.

CSCuj56845

  • On a Catalyst 4500 VSS using IOS Release XE 3.4.0SG to 3.4.2SG, or 3.5.0E, the show platform command may be truncated with a "Timed out" message and may rarely produce an unexpected reload. The likelihood of a reload increases if the command is issued over an SSH session or if the output is redirected to a file. The same behavior is observed using IOS Release XE 3.5.0 and the show tech command.

Workaround: None. CSCul00025

Open Caveats for Cisco IOS XE Release 3.5.0E

  • When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Information provider) increases substantially. The query time 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 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

  • 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

  • A device in a guest VLAN that is connected behind a phone 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 display flow statistics.

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

  • When MLD Snooping is disabled, a Catalyst 4500-X switch cannot maintain 6,000 MLD joins, causing traffic loss due to missing outgoing interfaces.

Workaround: Enable MLD snooping. CSCtx82176

  • When a Catalyst 4500-X uplink module is removed incorrectly, hardware forwarding tables are frozen, and baseboard ports remain connected for 20 to 25 seconds.

Workaround: Remove the Catalyst 4500-X module by first pressing the Ejector button for 10 seconds until the light turns green. CSCty67871

Caution: If you remove the module without following this procedure, the system always shuts down (or fails). Always use the Ejector button.

  • For the 10-Gigabit interface on a Catalyst 4500-X switch, link flaps are observed if the debounce interval is defined with the link debounce time command to within 1 second of the pulse interval.

For example, if the pulse interval is 250 ms and the debounce interval is 500 ms, then the delta is 250 ms and the debounce will be ineffective.

Workaround: Define a debounce interval that is at least 1 second greater than the incoming pulse interval. CSCtx75188

  • In a multichassis port channel on a VSS system with a very high number of link up and down events that occur within a second and typically causes an error-disable event, only the ports on the active switch are error-disabled due to flaps.

Workaround: None. CSCuc36612

  • If you enter the show spi-fc 12 command, a crash occurs.

Workaround: Use the show spi-fc all command to dump all SPI channel information. CSCuc81286

  • 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

  • Packets that are routed on the same Layer 3 interface (or SVI) that entered on are dropped if received on the VSS standby switch.

Workaround: None. CSCub63571

  • You can attach an input QoS policy to VSL member ports, but you cannot detach it. You only can configure VSL ports.

Workaround: Default the VSL member ports and detach the input QoS policy. CSCuc49150

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

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

  • 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

  • The POST results on the VSS standby switch displayed by the show diagnostic result module all detail command indicate module number 1 rather than 11. The module number is not interpreted by Cisco IOS.

Workaround: None. CSCuc73632

  • The following (information-only) error message and traceback may occur during MFIB-to-platform state updates for Bidirectional PIM (*,G/m) entries associated with Bidirectional PIM rendezvous points:
%SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "MFIB_mrib_read", ipl= 0, pid= 370
-Traceback= 1#f95b67f80cdf0886bbf15560d7553abc :152CC000+2699F4C :152CC000+269A310 :152CC000+1F1B55C :152CC000+38D5F4C :152CC000+2C25698 :152CC000+2C2EDF4 :152CC000+5F6F0B0 :152CC000+5F6F1A0 :152CC000+2C2F274 :152CC000+2C24AA4 :152CC000+119935C :152CC000+1D94244 :152CC000+119B070 :152CC000+119699C :152CC000+2C50D00 :152CC000+2B5901C
 

These messages are typically observed during SSO, bootup, or when a PIM-enabled interface undergoes a state transition on a switch containing Bidir PIM state entries.

Workaround: None. CSCud39208

  • Sometimes, after VSS comes up, the control links display different VSL links.

Workaround: Convert the VSS member switch to standalone and bring up VSS again. CSCug86547...Predator and K10

  • An IPv6 BFD session flaps if you configure a 100 * 3 timer value.

Workaround: Set the BFD timer and multiplier as 100 * 5. CSCuh35017

  • BFD supports 300ms and time values exceeding (100 * 3).

Workaround: None. CSCuh19345

  • Policer and Classification statistics do not increment during ISSU runversion when you downgrade from IOS Release XE 3.5.0E.

Workaround: This issue is transient. Policer and Classification statistics are available after ISSU completes. CSCuh90975

  • When a queuing policy is applied to a Layer 3 MEC member port, queuing statistics do not increment.

Workaround: None CSCuh76328

  • In a VSS (virtual switching system) setup, the show switch virtual link EXEC command displays VSL control link port numbers on different VSLs (virtual switching links) rather then displaying port numbers on the same link.

Workaround: Convert the VSS to a standalone setup. CSCug86547

  • A switch crashes when the you enter the show power inline module 1 and show power inline module 1 detail commands in two different telnet sessions and reset the linecard using a third telnet session.

Workaround: Reset the term length to 0 on the vty session. CSCuf08112

  • On configuring power inline consumption, the show power inline command might not display the values of the power consumed by the PD.

Workaround: Shut then no shut the interface. CSCue72897

  • The match application name and collect application name commands appear as available for flow record configuration (e.g., when using the ? help listings). However, this configuration is otherwise unsupported: the show flow monitor monitor-name cache command shows the application name as 'unknown,’ and the application table is not exported, so this 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

  • Occasionally, when the VSL goes down on a VSS with fast-hello based dual-active detection, the Layer 2 convergence time exceeds the Layer 2 convergence time observed with e-pagp based dual-active detection by 20ms.

However, the Layer 2 convergence time of the former stills meet the sub-second convergence criteria.

Workaround: None. CSCui25034

  • The show memory debug leak command is unavailable.

Workaround: Use the show memory detailed process iosd debug leaks command. CSCui69486

  • If you configure SNMP proxy and immediately remove it, your switch crashes.

Workaround: Wait two min before removing the proxy. CSCug69823

  • FHS entries do not go down during a VSS switchover

Workaround: None. CSCub10404

  • CPU utilization rises and the console may hang on simultaneously executing the following commands from either two VTY's session, or from a Console and a VTY session.
show proc cpu <sorted|detailed|history>
show redundancy <>
show tech-support
 

Workaround: Execute these commands in a single session.

If you plan to execute those commands sequentially, close the console session before executing the show tech-support command. CSCuh15561

  • If no vlan.dat exists on both source and destination, the sync command fails (i.e., the synchronization between flash to sdflash or sdflash to flash doesn't happen).

Workarounds:

Skip the vlan.dat check.

Rename any config.text files as vlan.dat file. CSCue61001

  • While either performing an ISSU upgrade from XE 3.4.0 (or earlier) to XE 3.5.0 or performing a downgrade from XE 3.5.0 to an earlier release, the following “authmgr mtu mismatch” error messages might display:
