Cisco NX-OS Release 10.4(1)F became available.

New and Enhanced Software Features

New Features

Product Impact

Feature

Description

Security

 

VXLAN EVPN First Hop Security (IPv4)

In the earlier releases, DHCP-snooping and associated security features such as Dynamic ARP Inspection (DAI) and IP Source Guard (IPSG) were restricted to a single switch. With Cisco NX-OS Release 10.4(1)F, these features are supported on the entire VXLAN fabric. This allows a host that is authenticated on one VTEP to move to another VTEP through a trusted interface.

See Cisco Nexus 9000 Series NX-OS VXLAN Configuration Guide, Release 10.4(x).

Radius over DTLS Support

Datagram Transport Layer Security (DTLS) protocol is now used to  transport RADIUS datagrams over a secure channel using UDP.

See Cisco Nexus 9000 NX-OS Security Configuration Guide, Release 10.4(x).

Ease of Use

 

Port-channel load-balance command for MPLS tagged traffic

The port-channel load-balance command for MPLS tagged traffic feature allows you to configure MPLS load-balancing as an option in the existing port-channel load-balance command. This feature provides for optimal load-balancing over port channel.

See Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide, Release 10.4(x), and the Cisco Nexus 9000 Series NX-OS Label Switching Configuration Guide, Release 10.4(x).

Support to redirect/deny all packets using ePBR policy

From Cisco NX-OS Release 10.4(1)F, ePBR Layer 2 provides configuration options to redirect or deny all control traffic that match the ePBR policy to the service devices or service chain, without being consumed or intercepted.

See Cisco Nexus 9000 Series NX-OS ePBR Configuration Guide, Release 10.4(x), and Cisco Nexus 9000 Series NX-OS Security Configuration Guide, Release 10.4(x).

Split Loopback for VXLAN Multi-Site BGW Deployment

The PIP interface now advertises orphan host route (using type 2 routes) with PIP as next hop before the hold-down timer expires. This avoids traffic loss for the orphan host and optimizes vPC convergence.

 

See Cisco Nexus 9000 NX-OS VXLAN Configuration Guide, Release 10.4(x).

Feature Set

VXLAN QoS Outer Header Policy for Layer 2

Cisco NX-OS Release 10.4(1)F provides the default-vxlan-in-tnl-dscp-policy template in QoS policy-map type. This template matches the outer DSCP of the VXLAN packet and re-writes Class of Service (CoS) in the decapsulated ethernet packet on the egress VTEP.

See Cisco Nexus 9000 Series NX-OS VXLAN Configuration Guide, Release 10.4(x).

Support ARP response for out-of-subnet

With Cisco NX-OS Release 10.4(1)F, you can enable or disable the ARP out-of-subnet packet transaction on the connected host using the ip arp outside-subnet command. This command is available in both global and interface modes.

See Cisco Nexus 9000 Series NX-OS Unicast Routing Configuration Guide, Release 10.4(x).

ePBR out-of-service

This feature provides the ability to temporarily remove (shut down) an endpoint from service when a user-defined failure threshold is reached. The endpoints can be placed out-of-service by the following ways:

  Administrative out-of-service or
  Auto out-of-service

See Cisco Nexus 9000 Series NX-OS ePBR Configuration Guide, Release 10.4(x).

Deduplication

With Cisco NX-OS Release 10.4(1)F, the deduplication feature allows you to remove duplicate copies of the traffic flow when used with Nexus Data Broker (NDB) switches.

See Cisco Nexus 9000 Series NX-OS System Management Configuration Guide.

Egress NetFlow

Egress NetFlow identifies packet flows for outgoing IP packets and provides statistics based on these packet flows. The egress NetFlow uses ingress pipeline and ingress TCAM carving egr-netflow to record flow information egressing out of the switch.

See Cisco Nexus 9000 Series NX-OS System Management Configuration Guide

The enhanced features listed below are existing features introduced in earlier releases, but enhanced to support new platforms in Cisco NX-OS Release 10.4(1)F.

Open Issues

Bug ID                    

Description

CSCvw16064

Headline: NX-OS to be conformed with RFC 5424 (NILVALUE for STRUCTURED-DATA and MSGID fields)

Symptoms: In all Cisco NX-OS versions, the implementation of syslog does not follow RFC 5424 leading to following problems:

  Adding NILVALUE for STRUCTURED-DATA field as we don't have structured data currently in syslog messages.
RFC 5424:6.3.  STRUCTURED-DATA
In case of zero structured data elements, the STRUCTURED-DATA field   MUST contain the NILVALUE.
  Adding NILVALUE for MSGID in syslog header as this must be there if no data is available for MSGID.
For the rest fields like APP-NAME, PROCID NILVALUE is not mandatory.

Workarounds: None

CSCwf51439

Headline: VXLAN: BUM Traffic Loop when PIM BiDir and Fabric Peering are used together.

Symptoms: Any Broadcast Unknown Unicast Multicast (BUM) packet will be looped between the 2 switches in vPC Fabric Peering until interface's bandwidth is exhausted, which will result in loss of connectivity to all the devices to the downstream VTEP as well as other VTEPs connected to the same SPINE.

Workarounds: Remove PIM BiDir and use PIM ASM or Ingress replication.

CSCwh17302

Headline: HMM /32 vrf leaking is not working with maximum-paths mixed.

Symptoms: The following symptoms occur:

Trying to leak a /32 prefix from source VRF-A to target VRF-B  on a pair of Nexus 9000 switches

Source-vrf views the /32 prefix locally from HMM

Target VRF does not leak the /32 prefix

When searching for the /32 prefix on the RIB only less specific route is leaked (less specific prefix is coming redistribute-direct of  SVI subnet where /32 is attached)

Workarounds: Perform any one of the following options:

Option 1: Clearing the less specific prefix on the target vrf resolves the problem

Option2: Remove <maximum-paths mixed> from the source VRF.

CSCwh22483

Headline: Cisco Nexus 9000  is not encapsulating properly MACsec traffic into VXLAN.

Symptoms: In a scenario where a MACsec packet's size exceeds 344-byte and needs to be sent over a VXLAN fabric, it is encapsulated. However, the information contained in the Total Length field in the IP header is not properly set. This behavior is also seen for the Length field in the UDP datagram header.

Workarounds: None.

CSCwh01493

Headline: Cisco Nexus 9300-FX3/GX random-detect threshold burst-optimized is causing packet drop.

Symptoms: The random-detect threshold burst-optimized command configured under class type queuing c-out-8q-q-default is causing drops on the interface where this service policy is applied.
The random-detect threshold burst-optimized ecn configuration causes the same issue.

Workarounds: Remove the random-detect threshold burst-optimized configuration.

CSCwh02830

Headline: Manual power cycle required while upgrading NX-OS N9K-C9500 switch with SUP A+ HW rev 1.0.

Symptoms: While upgrading the N9K-9500 switch, the following symptoms occur:

Nexus 9500 chassis with single or dual SUP A+ HW rev 1.0

Upgrade of Sup or SC EPLD (Just NXOS upgrade will not trigger this issue.)

After the reload, the active SUP module does not boot up and gets stuck with no console output and a continuously blinking amber STS LED.

Workarounds: The workaround is as follows:

1. Physically re-seat the module (cold power-cycle).

2. Remove all power to the chassis to allow the SUP module to power up again.

CSCwh19743

Headline: Nexus 9000 - flowcontrol send on configured on Port-channel after removing FEX HIF member ports.

Symptoms: The flowcontrol send on configuration is added automatically to Port-channel. A flowcontrol configuration added in this way cannot be modified.

Workarounds: Perform the no interface port-channel X command to manually remove the port-channel interface, and then recreate the port-channel.

Resolved Issues

Bug ID                    

Description

CSCwe06759

Headline: Memory leak at FEX unit.

Symptoms: When LACP based port-channels are configured between servers and FEX front-panel ports, memory leak takes place, resulting in memory depletion over a period of time. This causes the FEX device to start reloading, and it appears offline on the parent switch. After FEX is up, it appears online on the parent switch. This sequence can repeat whenever FEX reloads. When the FEX device reloads, loss of ingress traffic is noticed.

Workarounds: None

CSCwe20605

Headline: Encrypted tunnel (VXLAN Cloudsec) traffic is getting dropped on Cisco Nexus 9300-FX3 switch.

Symptoms: After upgrading Cisco Nexus 9300-FX3 switch to Cisco NX-OS Release10.3(2)F image, few or all encrypted tunnel traffic is dropped. VXLAN Cloudsec or tunnel encryption statistics do not update.

Workarounds: The workaround is as follows:

1.      Remove tunnel-encryption from DCI uplinks.

2.      Copy running-config startup-config.

3.      Reload the switch.

4.      Post reload, configure tunnel-encryption on DCI uplinks.

Headline: Kernel panic due to Fatal Module Error after ND ISSU on N9K-C9348GC-FXP switch.

Symptoms: After ND-ISSU, an unexpected reload due to kernel panic is noticed in N9K-C9348GX-FXP switches. This symptom can be verified by running either the show logging onboard internal reset-reason command or the show system reset-reason command. The output shows Reset Requested due to Fatal Module Error.

Workarounds: Use disruptive or normal upgrade procedure.

CSCwe50502

Headline: Cisco Nexus 9000 Unexpected Reload due to Watchdog with High ktah_nl_asic_isr Interrupts.

Symptoms: A Nexus 9000 switch running Cisco NX-OS Release 9.3(9) may reload unexpectedly with the reason - Watchdog Timeout - due to a high amount of ktah_nl_asic_isr hardware interrupt events seen in a kernel panic log.

Workarounds: None.

CSCwf11514

Headline: Cisco Nexus 9000-R - Inner DSCP rewritten to Outer DSCP on DECAP for MPLS Traffic.

Symptoms: The last three bits of the DSCP field are set to zero. For example, a packet that ingresses with DSCP 18 (010010) egresses with DSCP 16 (010000).

Workarounds: Removing mpls ip from the ingress interface can mitigate this issue.

CSCwf20782

Headline: Nexus 9000 – N2K HIF interface configurations erased while upgrading to Cisco NX-OS Release 10.2(4).

Symptoms: While upgrading Nexus 9000 disruptively from Cisco NX-OS Release 9.3(11) to 10.2(4), configurations on all N2K HIF interfaces are partially erased resulting in loss of traffic. Interfaces are in inactive status, as switchport access vlan x is missing from the HIF interfaces.

Workarounds: Default the affected interfaces and reconfigure.

CSCwf21754

Headline: After the reload ascii command, VRF ID always points to default when traffic flow is through the SVI interface.

Symptoms: When the Cisco Nexus 9500 switch is reloaded with the reload ascii command, the netflow export sends ingressVRF-id as default VRF-id(1).

Workarounds: Reload the switch.

CSCwf24420

Headline: Need to disable PIE feature and command from Cisco Nexus 9808 switches.

Symptoms: PIE commands do not show right output for fan, power supply, and optics.

Workarounds: None.

CSCwf32021

Headline: PTP process crash.

Symptoms: When PTP profile mode is 8275.1 on Cisco 9300-FX3 platform, PTP process crashes.

Workarounds: Disable PTP with the no feature ptp command.

CSCwf42887

Headline: On Cisco Nexus 9300-FX3 switches, VXLAN storm-control policer fabric bandwidth does not update after fabric link flap.

Symptoms: On Cisco Nexus 9300-FX3 switches, when VXLAN multisite uses evpn storm-control, flapping fabric link does not lead to VXLAN storm-control policer fabric bandwidth update.

Workarounds: Reset the policer using the shut/no-shut multi-site loopback command. Then disable evpn storm-control.

CSCwf57648

Headline: Nexus 9500 -R modules incorrect outer DMAC after initialization.

Symptoms: Nexus 9500 with -R line cards to perform an MPLS to VXLAN handoff. The Nexus 9500 that acts as the PE device adds an incorrect DMAC to the outer VXLAN header, which is causing the downstream VXLAN leaf to drop the packet.

Workarounds: If the switch is found to be in this state a reload ascii command will fix the mis-programming.

CSCwf67373

Headline: The copy r s command is aborted after ND-ISSU from older releases to Cisco NX-OS Release 10.2(1)F and beyond with FEX.

Symptoms: The copy r s command is aborted after ND-ISSU from older releases to Cisco NX-OS Release 10.2(1)F and beyond with FEX.

The layer for FEX ports is inconsistent between DME and backend. The DME has Layer 2 for FEX ports. When the DME tries to configure VLANs, the vlan_mgr rejects the configuration in the backend as it is Layer 3 in the backend. The correct layer is Layer 3. When nxapi retries in a continuous loop, the copy r s command gets aborted.

Workarounds: To recover the switch, configure switchport/no switchport on all the affected interfaces.

CSCwf69556

Headline: Nexus 9000: Interface description includes string "%n" or "%In" crashes Service port-profile.

Symptoms: An error occurs when we put the string %n or %In as interface description.

Workarounds: Do not use %n or %In string in interface description.

CSCwf75862

Headline: Bi-dir traffic received on DF winner interface is dropped towards the RPF (RP).

Symptoms: The symptoms are as follows:

1.     Bi-dir traffic received on DF winner interface is dropped towards the RPF (RP).

2.     All consistency checkers are clean.

3.     Elam summary shows forward.

4.     Elam detail shows RPF failure.

Workarounds: None.

CSCwf79132

Headline: After ISSU upgrade performed with maintenance mode SVIs stay down.

Symptoms: On Cisco Nexus 9000, all SVIs remain down after exiting maintenance mode post ISSU upgrade.

Workarounds: To restore the SVIs, reboot the switch.

CSCwf84373

Headline: Admin shut the mgmt0 interface, other end port remains up/flapping.

Symptoms: When interface mgmt0 is connected through SFP directly, the following symptoms are seen:

1.     Admin shut the mgmt0 interface.

2.     The port at the other end starts flapping (up/down).

3.     Add media-type sfp under mgmt0.

4.     No more flaps on the other end, but it still shows as up, while mgmt0 is admin down.

Workarounds: None.

[1] For specific fan speeds see the Overview section of the Hardware Installation Guide.
[2] This switch runs with +1 redundancy mode so that if one fan fails, the switch can sustain operation. But if a second fan fails, this switch is not designed to sustain operation. Hence before waiting for the major threshold temperature to be hit, the switch will power down due to entering the fan policy trigger command.
