=============================
To perform a software upgrade or downgrade, follow the instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide, Release 7.x.
For information about an In Service Software Upgrade (ISSU), see the Cisco NX-OS ISSU Support application.
Note: Upgrading from Cisco NX-OS 7.0(3)I1(2), 7.0(3)I1(3), or 7.0(3)I1(3a) requires installing a patch for Cisco Nexus 9500 platform switches only. For more information on the upgrade patch, see Upgrade Patch Instructions.
This section lists limitations related to Cisco NX-OS Release 7.0(3)I7(2).
■ When you upgrade a Cisco Nexus 9000 device to Cisco NX-OS Release 7.0(3)I7(2), if a QSFP port is configured with the manual breakout command and is using a QSA, the configuration of the interface Ethernet 1/50/1 is no longer supported and will need to be removed. To restore the configuration, you must manually configure the interface Ethernet 1/50 on the device.
■ Auto-negotiation is not supported on 25-G Ethernet transceiver modules on Cisco Nexus 9200 and 9300-FX platform switches, and Cisco Nexus 9500 platform switches that use N9K-X9700-EX line cards.
■ On the Cisco Nexus 9364C switches, auto-negotiation might not work on ports 49-64 when bringing up 100G links using the QSFP-100G-CR4 cable. The workaround for this issue is that you must hard code the speed on ports 49-64 and disable auto-negotiation.
■ We recommend using multicast heavy template for optimal bandwidth utilization when using multicast traffic flows.
■ IPv6 multicast is not supported on Cisco Nexus 9500 platform switches.
■ The following features are not supported on the Cisco Nexus 9364C switch.
o 100 G port cannot support breakout (HW limitation)
o FEX
o ISSU
o Segment routing
o Tetration (HW limitation)
NOTE: For the Cisco Nexus 9364C switch, the 930-W DC PSU is supported in redundancy mode if 3.5 W QSFP+ modules or passive QSFP cables are used and the system is used in 40 C ambient temperature or less. For other optics or higher ambient temps, 930-W DC is supported with two PSU’s in non-redundancy mode only.
■ VXLAN/EVPN integration is not supported on the Cisco Nexus 9348GC-FXP switch.
■ If the speed group is configured, the default interface command displays the following error:
Error: default interface is not supported as speed-group is configured
■ Line rate cannot be sustained across all 36 ports on the 9736C-EX line card.
■ Q-in-VNI has the following limitations:
switch (config-if-nve)# no overlay-encapsulation vxlan-with-tag
!Command: show running-config interface nve1
!Time: Wed Jul 20 23:26:25 2016
host-reachability protocol bgp
member vni 900001 associate-vrf
o Single tag is not supported on Cisco Nexus 9500 platform switches; only double tag is supported.
■ hardware profile front portmode command is not supported on the Cisco Nexus 9000 Series switches.
■ PV (Port VLAN) configuration through an interface range is not supported.
■ neighbor-down fib-accelerate command is supported in a BGP-only environment.
■ PortLoopback and BootupPortLoopback tests are not supported.
o no speed–Auto negotiates and advertises all speeds (only full duplex).
o speed 1000–Auto negotiates and advertises pause (advertises only for 1000 Mbps full duplex).
■ TCAM resources are not shared when:
o Applying VACL (VLAN ACL) to multiple VLANs
o Routed ACL (Access Control List) is applied to multiple SVIs in the egress direction
■ The following switches support QSFP+ with the QSFP to SFP/SFP+ adapter (40 Gb to 10 Gb):
Note: The Cisco Nexus 9396PX, 9396TX, 93128TX, 93120TX, 9332PQ, 9372PX, 9372PX-E, 9372TX, and 9272TX-E platforms support for the QSFP+ breakout has the following limitations:
■ 1 Gb with QSFP-to-SFP adapter is not supported.
■ For the Cisco Nexus 9332PQ switch, all ports except 13-14 and 27-32 can support breakout.
■ The following switches support the breakout cable (40-Gb ports to 4x10-Gb ports):
o N9K-C93180LC-EX—last four ports are breakout capable (10x4, 24x4, 50x2)
o N9K-X9732C-FX line card
■ Weighted ECMP (Equal-Cost Multi-Path) is not supported on the Cisco Nexus 9000 Series switches.
■ Limitations for ALE (Application Link Engine) uplink ports are listed at the following URL:
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/ale_ports/b_Limitations_for_ALE_Uplink_Ports_on_Cisco_Nexus_9000_Series_Switches.html
This section provides guidelines and limitations for configuring private VLANs.
■ Secondary and Primary VLAN Configuration
■ Private VLAN Port Configuration
■ Limitations with Other Features
For more information, see the Cisco Nexus 9000 Series NX-OS Layer 2 Switching Configuration Guide.
Private VLANs have the following configuration guidelines and limitations:
■ Private VLANs must be enabled before the device can apply the private VLAN functionality.
■ VLAN interface feature must be enabled before the device can apply this functionality.
■ PVLANs support port modes as follows:
■ PVLANs are mapped or associated depending on the PVLAN trunk mode.
■ PVLANs support the following:
¯ PACLs (Port Access Control Lists)
¯ PVLAN across switches through a regular trunk port
¯ RACLs (Router Access Control Lists)
■ PVLANs support SVIs as follows:
¯ HSRP (Hot Standby Router Protocol) on the primary SVI
¯ Primary and secondary IPs on the SVI
¯ SVI allowed only on primary VLANs
■ PVLANs support STP as follows:
¯ MST (Multiple Spanning Tree)
¯ RSTP (Rapid Spanning Tree Protocol)
■ PVLANs port mode is not supported on the following:
¯ 40-Gb interfaces of the Cisco Nexus ALE ports on Cisco Nexus 9300 platform switches.
■ PVLANs are supported on breakout ports for the Cisco Nexus 9200 and 9300-EX platform switches.
■ PVLANs do not provide support for the following:
¯ DHCP (Dynamic Host Channel Protocol) snooping
¯ IP multicast or IGMP snooping
¯ SPAN (Switch Port Analyzer) when the source is a PVLAN VLAN
■ For more details, see the Cisco Nexus 9000 Series NX-OS Layer 2 Switching Configuration Guide.
Follow these guidelines when configuring secondary or primary VLANs in private VLANs:
■ VLAN configuration (config-vlan) mode must be used to configure PVLANs.
■ For normal trunk ports, note the following:
¯ Separate instances of STP exist for each VLAN in the private VLAN.
¯ STP parameters for the primary and all secondary VLANs must match.
¯ Primary and all associated secondary VLANs should be in the same MST instance.
■ For PVLAN isolated trunk ports, note the following:
■ Before configuring a VLAN as a secondary VLAN, you must shut down the VLAN network interface for the secondary VLAN.
Follow these guidelines when configuring private VLAN ports:
Consider these configuration limitations with other features when configuring PVLAN:
■ After configuring the association between the primary and secondary VLANs:
¯ Static MAC addresses for the secondary VLANs cannot be created.
¯ Dynamic MAC addresses that learned the secondary VLANs are aged out.
■ In PVLANs, STP controls only the primary VLAN.
■ PVLAN host or promiscuous ports cannot be SPAN destination ports.
■ PVLAN ports can be configured as SPAN source ports.
■ vPC pairing between T2 and TH platforms is not recommended.
■ Post-routed flood is not supported.
■ The configuration is purged when:
o Straight-through FEXs are converted to dual-homed
o Dual-homed FEXs are converted to Straight-through.
There are two cases for dual-home to straight-through conversion:
For more information, see the Cisco Nexus 2000 Series NX-OS Fabric Extender Configuration Guide for Cisco Nexus 9000 Series Switches, Release 7.x.
