Introduction

Cisco NX-OS software is a data center-class operating system designed for performance, resiliency, scalability, manageability, and programmability at its foundation. The Cisco NX-OS software provides a robust and comprehensive feature set that meets the requirements of virtualization and automation in mission-critical data center environments. The modular design of the Cisco NX-OS operating system makes zero-impact operations a reality and enables exceptional operational flexibility.

The Cisco Nexus 9000 Series uses an enhanced version of Cisco NX-OS software with a single binary image that supports every switch in the series, which simplifies image management.

- PTP is supported on N9K-C93128TX.

- DHCP relay is supported on VxLANs with the server and client on the same VRF while the server and client are on different VTEPs.

Installation Notes

Upgrade Instructions

Downgrade Instructions

Disable the Guest Shell if you need to downgrade from Cisco NX-OS Release 7.0(3)I1(1a) to an earlier release.

Software Maintenance Upgrades

Note If you perform a software maintenance upgrade (SMU) and later upgrade your device to a new Cisco NX-OS software release, the new image will overwrite both the previous Cisco NX-OS release and the SMU package file.

Limitations

This section lists limitations related to Cisco NX-OS Release 7.0(3)I1(1a).

- Layer 3 routed traffic for missing Layer 2 adjacency information is not flooded back onto VLAN members of ingress units when the source MAC address of routed traffic is a non-VDC MAC address. This limitation is for hardware flood traffic and can occur when the SVI has a user-configured MAC address.

- DHCP relay with VxLAN is supported only in the following two scenarios:

– When the server is reachable through the default VRF.

– When the server and client are in the same VRF.

- The neighbor-down fib-accelerate command is supported in a BGP-only environment.

- The uplink module should not be removed from a Cisco Nexus 9300 Series switch that is running Cisco NX-OS Release 7.0(3)I1(1a). The ports on the uplink module should be used only for uplinks.

- The PortLoopback and BootupPortLoopback tests are not supported.

- The ASIC Memory-NS test is applicable only for the N9K-X9564PX and N9K-X9564TX line cards.

- Priority flow control (PFC) is supported on Cisco Nexus 9500 Series switches with the N9K-X9636PQ line card. It is not yet supported on Cisco Nexus 9300 Series switches and Cisco Nexus 9500 Series switches with the N9K-X9564PX or N9K-X9564TX line card.

- If you configure the FEX with 100/full-duplex speed and you do not explicitly configure the neighboring device with 100/full-duplex speed, the data packet traffic does not pass properly even though the link appears to be “up.”

– no speed–Auto negotiates and advertises all speeds (only full duplex).

– speed 100–Does not auto negotiate; pause cannot be advertised. The peer must be set to not auto negotiate (only 100 Mbps full duplex is supported).

– speed 1000–Auto negotiates and advertises pause (advertises only for 1000 Mbps full duplex).

- Eight QoS groups are supported only on modular platforms with the following Cisco Nexus 9500 Series line cards:

– N9K-X9636PQ

– N9K-X9464PX

– N9K-X9464TX

– N9K-X9432PQ

- In a non-BGP eVPN environment, the SVI for L2/L3 boundary is expected to be on a non-VTEP routing block (a router attached to a VTEP).

- Cisco NX-OS Release 7.0(3)I1(1a) does not support these features from the Cisco Release 6.1(2)|3(3):

– The source interface support for traceroute feature.

– The Cisco NX-OS to ACI conversion feature with the ability to boot the ACI image from Cisco NX-OS mode instead of from the loader> prompt.

– The port-channel subinterface feature is not supported.

- Cisco NX-OS Release 7.0(3)I1(1a) supports flooding for Microsoft Network Load Balancing (NLB) unicast mode on Cisco Nexus 9500 Series switches but not on Cisco Nexus 9300 Series switches. NLB is not supported in max-host system routing mode. NLB multicast mode is not supported on Cisco Nexus 9500 or 9300 Series switches.

Note To work around the situation of Unicast NLB limitation, we can statically hard code the ARP and MAC address pointing to the correct interface. Please refer to bug ID CSCuq03168 in detail in the “Open Caveats—Cisco NX-OS Release 7.0(3)I1(1a)” section.

- TCAM resources are not shared when:

– Routed ACL is applied to multiple SVIs (switched virtual interfaces) in the egress direction.

– Applying VACL (VLAN ACL) to multiple VLANs.

- Cisco Nexus 9000 Series hardware does not support range checks (layer 4 operators) in egress TCAM. Because of this, ACL/QoS policies with layer 4 operations-based classification need to be expanded to multiple entries in the egress TCAM. Egress TCAM space planning should take this limitation into account.

- Applying the same QoS policy and ACL on multiple interfaces requires applying the qos-policy with the no-stats option to share the label.

- Limitations for ALE uplink ports are listed at the following URL:

Unsupported Features

This section lists features that are not supported in the current release.

- VXLAN

- PVLANs

- DHCP

- FEX

- Other Unsupported Features

VXLAN

This section lists VXLAN features that are not supported.

- VXLAN is not supported on Cisco Nexus 9500 Series switches.

- TX SPAN (Switched Port Analyzer) for VXLAN traffic is not supported for the access-to-network direction.

- QoS classification is not supported for VXLAN traffic in the network-to-access direction.

- QoS buffer-boost feature is not applicable for VXLAN traffic.

- ACL and QoS for VXLAN traffic in the network-to-access direction is not supported.

- Native VLANs for VXLAN are not supported. All traffic on VXLAN Layer 2 trunks needs to be tagged.

- Consistency checkers are not supported for VXLAN tables.

- vPC type-1 consistency checkers are not supported for VXLAN configurations.

- BGP eVPN neighbors are not supported over vPC interfaces.

- VXLAN routing and VXLAN Bud Nodes features on the 3164Q platform are not supported.

- DHCP snooping and DAI features are not supported on VXLAN VLANs.

- IGMP snooping is not supported on VXLAN VLANs.

- Configuring an RP (rendezvous point) on a VTEP device is not supported. When configuring a multicast group, the RP should be configured on non-VTEP devices.

VXLAN Topology Restrictions

- FEX host interface ports are not supported for VLANs extended with VXLAN.

- SVI uplinks are not supported on a VTEP when VTEP is in a Bud-Node topology (transit and gateway roles).

VXLAN ACL Limitations

The following ACL related features are not supported:

- Ingress RACL that is applied on an uplink Layer 3 interface that matches on the inner or outer payload in the network-to-access direction (decapsulated path)

- Egress RACL that is applied on an uplink Layer 3 interface that matches on the inner or outer payload in the access-to-network direction (encapsulated path)

- Egress VACL for decapsulated VXLAN traffic

We recommend that you use a PACL or VACL on the access side to filter out traffic entering the overlay network.

PVLANs

Private VLANs (PVLANs) are not supported.

DHCP

DHCP subnet broadcast is not supported.

FEX

- FEX is supported only on the Cisco Nexus 9372PX and 9396PX switches. It is not supported on the other Cisco Nexus 9300 Series switches or the Cisco Nexus 9500 Series switches.

- ASCII replay with FEX needs be done twice for HIF configurations to be applied. The second time should be done after the FEXs have come up.

- IPSG is not supported on FEX ports.

Other Unsupported Features

The following lists other features not supported in the current release:

- Due to a Poodle vulnerability, SSLv3 is no longer supported.

- The Cisco Nexus 9300 Series switches and the Cisco Nexus 3164Q switch do not support the 64-bit ALPM routing mode.

- IPSG is not supported on the following:

– The last 6 40G physical ports on the 9372PX, 9372TX, and 9332PQ switches

– All 40G physical ports on the 9396PX, 9396TX, and 93128TX switches
