New Software Features

 

Table 5 New Software Features in this Release
Feature Name
Description

DHCPv6 Options
  • DHCPv6 Option 52, Control and Provisioning of Wireless Access Points (CAPWAP) Access Controller —A protocol that allows lightweight access points to use DHCPv6, to discover a Wireless Controller to which it can connect. CAPWAP is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points.
  • DHCPv6 Option18—Refers to the interface-ID option, which is used by relay agents to decide which interface should be used when forwarding a RELAY-REPLY packet. If a relay agent receives a RELAY-REPLY message with an interface-ID option, the message is relayed to the client through the interface identified by the option.
  • DHCPv6 Option 37, Relay Options Remote-ID—Adds the remote identification (remote-ID) option to relayed (RELAY-FORWARD) DHCPv6 packets.

(IP Base and Enterprise Services)

IPv6 Object Group ACLs (OGACLs)

Introduces support for IPv6 OGACLs. Object groups enable you to group ACE entries and add or remove entries while keeping your ACL structure more readable.

(IP Base and Enterprise Services)

Flexible NetFlow (FNF) for AVC with DNS-AS

Introduces the ability to export application information using FNF. This enables you to gain visibility into the applications running on your network, and the use of FNF option templates to export application ID, description, and attribute information.

(IP Base and Enterprise Services)

VRF-Aware Security Group Tag (SGT)

Introduces support for

  • Subnet-to-SGT mapping. This mapping binds an SGT to all host addresses of a specified subnet.
  • VLAN-to-SGT mapping. This mapping binds an SGT to packets from a specified VLAN.

Description

Downshift Support on Multigigabit (mGIG) Ethernet Interfaces

Introduces support for downshifted or lowered speeds on mGIG interfaces, automatically, if the link quality is poor or if the link is continuously down.

(LAN Base, IP Base, Enterprise Services)

MKA MACsec Enahancements
  • Supports MKA MACsec Pre-shared keys (PSKs) that are used to generate Connectivity Association Keys (CAKs), Key Encryption Keys (KEK), and Integrity Check Value Keys (ICK), when configuring switch-to-switch links.
  • Supports port channels

(Enterprise Services)

Multicast VLAN Registration

The maximum number of supported MVR groups is now increased to 1500.

(LAN Base, IP Base, Enterprise Services)

Programmability

The capability to configure and manage networking devices using protocols that are specifically designed to be consumed by software, that is, machine to machine interfaces.

The feature provides the use of NETCONF and RESTCONF interfaces, which reside in a container on the switch and enable remote management. The YANG data models available with these interfaces determine the scope of functions or actions that can be performed.

Supported YANG Data Models include the Cisco device-specific ned.yang model (a configuration data model) and the NETCONF Operational Data Manager (ODM) (operational and state data).

The feature also introduces support for the Preboot Execution Environment (PXE boot), a network boot loader, which supports booting from a network-based source. It enables the switch to retrieve the software image, and other files from a remote server during initial deployment, without end-user intervention, that is, Zero-Touch Provisioning.

The PXE boot feature requires ROMMON version 15.0(1r)SG14.

(LAN Base, IP Base, Enterprise Services)

VNET IP Addressing Inheritance Overrides on Subinterfaces

Allows the creation of separate IP addresses for subinterfaces, using the vnet interface configuration mode, overriding the IP address inherited from the main trunk interface.

(Enterprise Services)

New Features in Cisco IOS XE Release 3.9.0E

New Software Features

 

Table 8 New Software Features in this Release
Feature Name
Description

Application Visibility and Control (AVC) with Domain Name System-Authoritative Source (DNS-AS)

Provides a centralized means of controlling the identification and classification of trusted network traffic. It accomplishes this by using metadata stored in an authoritative DNS Server to identify applications and domains and provide traffic classification and business relevance information. Modular QoS CLI (MQC) configuration settings on the switch (DNS-AS Client) determine the policies that are enforced.

The feature is disabled by default.

(IP Base and Enterprise Services)

MACSec Agreement (MKA) MACsec with EAP-TLS

Provides support for IEEE 802.1X Port-based Authentication with Extensible Authentication Protocol- Transport Layer Security (EAP-TLS), to configure MKA MACsec on switch-to-switch links.

(IP Base and Enterprise Services)

Cisco-Port-QoS-MIB: Support for cportQosQueueEnqueuePkts and cportQosQueueDropPkts

Support for the following objects in Cisco-Port-QoS-MIB to manage queue counters on the device:

  • cportQosQueueEnqueuePkts - indicates the number of egress packets enqueued for a queue and threshold
  • cportQosQueueDropPkts - indicates the number of egress packets that have been dropped for a queue and threshold.

Upgrading the System Software

If you are upgrading to Cisco IOS XE Release 3.9.xE and plan to use VSS, you must upgrade your ROMMON to IOS Version 15.0(1r)SG11.

ISSU is supported on 4500-X in VSS configuration.

Limitations and Restrictions

  • mGRE with NHRP (DMVPN) is not supported.
  • Starting with Cisco IOS XE Release 3.9.0E, Secure Shell (SSH) Version 1 is deprecated. Use SSH Version 2 instead.
  • The maximum MTE supported on Catalyst 4500 switches is 8000, per direction.
  • Although the show memory command is supported on Catalyst 4500 series switches, the CLI output for the command shows the value 0 for the config total, on Catalyst 4500 series switches using a daughter card on Supervisor Engine 7-E. This issue is, however, not seen on switches with Supervisor Engine 7-E baseboard. (CSCup28930)
  • When you install the GLC-T (1000Base-T) SFP transceiver,  10/100 Mbps with auto negotiation is not supported.
  • When you use the GLC-GE-100FX module between a Cisco Catalyst 4500-X switch and a Cisco Catalyst 2000 or 3000 series switch, traffic does not flow after the first time you change the interface from half duplex to a full duplex.

Workaround : You have to enter the shutdown and then the no shutdown interface configuration command for traffic flow to resume. (CSCus14532)

  • The system allows you to delete policy maps related to these Auto QoS profiles:

–blank.gif Auto QoS enterprise

–blank.gif Auto QoS guest

–blank.gif Auto QoS voice

The problem is seen on a Catalyst 4500 series switch running Cisco IOS-XE release 3.7.0E, when you configure QoS using Auto Qos and you try to delete an Auto QoS profile related policy map.

Workaround : To recover the deleted policy-map, remove all the policies related to that profile, remove Auto QoS configuration from the WLAN, and then reconfigure Auto QoS.

  • VSS: Do not use SVLAN for routing in SP network on ingress switch (where the mapping is present). This is not a valid scenario.
  • 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.
  • Performing an ISSU from a prior release to IOS XE 3.6.0E is not supported.
  • 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 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:

–blank.gif Decrease the number of monitors.

–blank.gif 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:

–blank.gif At least 10K groups and roughly 20K mroutes exist.

–blank.gif 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:

–blank.gif Links flap for various Layer 3 protocols.

–blank.gif 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

  • 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
 
Image load status: 0x00000000

  • When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may crash. As a workaround, disable the logging discriminator on the device (CSCur45606, CSCur28336).
