New and Enhanced Software Features

New Features

Feature

Description

Cisco Application Framework (CAF)

Beginning with Cisco NX-OS Release 10.3(1)F, Cisco Application Hosting Framework is integrated into NX-OS.

The Cisco NX-OS Application Hosting Framework provides manageability and networking models for running a guest application. The virtualization infrastructure allows an administrator to define a logical interface that specifies the connectivity between the host and the guest. Cisco NX-OS maps the logical interface into a Virtual Network Interface Card (vNIC) that the guest application uses.

The Cisco application-hosting framework is an NX-OS Python process that manages virtualized and container applications that run on devices.

Application hosting provides the following services:

●  Launches designated applications in containers.

●  Checks available resources (memory, CPU, and storage), and allocates and manages them.

●  Provides support for console logging.

●  Provides access to services through REST APIs.

●  Provides a CLI endpoint.

●  Provides an application-hosting infrastructure referred to as Cisco Application Framework (CAF).

●  Helps set up platform-specific networking (packet-path) through a special application bridge interface.

For more information, refer Cisco Nexus 9000 Series NX-OS Programmability Guide and Cisco Nexus 3000 and 9000 NX-API References, Release 10.3(x).

Flow visibility in Nexus Dashboard Insights and NetFlow

In the earlier releases, NetFlow and Analytics were mutually exclusive features, and the users could only use the standard V9 export from CPU for NetFlow. Beginning with Cisco NX-OS Release 10.3(1)F, both NetFlow and Analytics can co-exist and use the standard V9 export from CPU. Using this mixed mode feature results in decreased processing load on the collectors.

For more information, see Cisco Nexus 9000 Series NX-OS System Management Configuration Guide, Release 10.3(x).

The enhanced features listed below are existing features introduced in earlier releases but enhanced to support new platforms in Cisco NX-OS Release 10.3(1)F.

Open Issues

Bug ID

Description

CSCwc56079

Headline: High PTP correction on -R line cards on 2 PTP GMs failover

Symptoms: On the Cisco Nexus 9000 fabric, high PTP correction is seen on -R-Series based line cards on Nexus 9500 (more than ~600 ns) during PTP GM fail over with different GM ID.

Workarounds: None

CSCwa76388

Headline: Cisco Nexus 9000 TOR/EOR -R platforms add hardware counters in show tech module all

Symptoms: Enhancement of show tech to collect additional hardware counters

Workarounds: None

CSCwc45694

Headline: TapAgg- GX: vlan tag is missing on captured packets with reload ascii

Symptoms: On GX series switch after ASCII reload, vlan tag is missing on the egress interface when TapAgg is configured to redirect traffic.

Workarounds: Remove and reapply "mode tap-aggregation" config under the interface.

CSCwc02916

Headline: N9K-X9600 LCs: L3VNI add deletion causes traffic drop

Symptoms: Traffic Decap fails with VNI=0, could not derive VSI to lookup RIF

Workarounds: Remove and add VLAN to VNI.

CSCwb91169

Headline: Configuration replace (CR) operation not working, while changing configs under "set community" or "set large-community"

Symptoms: Configuration replace (CR) operation fails while trying to delete a community under route-map.

Workarounds:

1. Manually remove the offending configurations - 'no set community 2:200'. (Performing/not performing CR after this will have the same no-op effect)

OR

2. Manually remove all 'set community' configurations by running 'no set community' under route-map first, then perform CR with target file that contains 'set community 1:10'.

OR

3. Two-stage CR:

a. First, CR with target file that does not have any set community command. This will wipe all set community configs from running. (Can be achieved by deleting all ‘set community’ strings from required target-file)

b. Next, CR with target file that contains 'set community 1:10'

CSCwc63772

Headline: NF records are not parsed correctly after parameter "match ipv6 destination address" is removed

Symptoms: When the configuration of a record changes it generates new templates that must be used for all future record exports. In this defect, records were still being exported using old templates.

Workarounds: Remove and reapply the IPv4/IPv6 monitors under the interfaces affected. Do this for each unique monitor.

CSCwc76568

Headline: Arp-suppression vlan suspended post ND-suppression enable and reload

Symptoms: For ND Suppression VACL to work, increase the SUP TCAM size to 768 or above using the hardware access-list tcam region sup-tcam 768 command.

This needs a reload if the previous SUP TCAM Size is < 768. However, if the System is already configured at 768 or above, no reload is needed. In no reload case - Vxlan vni vlans may get suspended in a vPC deployment.

Workarounds: Reload the peer that was not reloaded after enabling ND suppression.

CSCwb63451

Headline: Upgrade to 10.3(1)F fails from older NXOS releases.

Symptoms: Upgrade will fail from older releases [Any code before 9.3(10) and any 10.x code before 10.2(3)F] to 10.3(1)F or later. This impacts PIDs that boot with the 'cs' image. This will be seen for install all upgrades as well as boot variable change.

Workarounds: There are two work-arounds options available:

1. Apply available SMU for releases 9.3(9) and earlier or 10.2(2)F and earlier. Then upgrade directly to 10.3(1)F or later.

OR

2. Perform a multi-step upgrade - First upgrade to fixed release 9.3(10) and later 9.3(x) code or 10.2(3)F and later 10.2(x). Then upgrade to 10.3(1)F and later.

CSCwe02448

Headline: Cisco N9K-C9808 – Fan Modules and Line Cards shut down due to Fans or PSUs not coming up.

Symptoms: After completing NX-OS bootup, Fabric Modules and Line Cards are shut down due to multiple fans or power supplies not coming up.

Workarounds: You can avoid this issue by upgrading NX-OS to Cisco NX-OS Release 10.3(2)F.

CSCwe67205

Headline: Credit Loss Recovery is not triggered for FC interface with no transmit credits.

Symptom: A Fibre Channel interface that stays at 0 transmit credits is not recovered by the Credit Loss Recovery agent.

Workaround: If the interface has switchport ignore bit-errors configured, then remove it with the no switchport ignore bit-errors interface configuration command.

CSCwh50989

Headline: Custom COPP causing transit traffic to be punted to the CPU on Nexus 9300-GX2

Symptom: When custom-COPP policy contains ACL rules which match on Layer 4 destination or source port, transit traffic also hits the COPP and the packets are copied to CPU. This causes duplication of traffic as CPU also routes the copied packets to the destination.

Workaround: Custom COPP policy using src/dst match mitigates punt for transit traffic.

Resolved Issues

[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.
