Upgrade Matrix

This section provides information on upgrading Cisco Nexus 3000 and 3100 Series switches to Cisco NX-OS Release 7.0(3)I2(1).

Note: Beginning with this release, kickstart and system images are no longer used to install the Cisco NX-OS software image on Cisco Nexus 3000 and 3100 Series switches. Instead, a single binary image is used (for example, nxos.7.0.3.I2.1.bin). To install the software, you would use the install all nxos bootflash:nxos.7.0.3.I2.1.bin command.

Limitations

Recommended Procedure

6.0(2)U6(3)

7.0(3)I2(1)

None

Install all and fast reload are the only upgrade methods supported because of a BIOS upgrade requirement.

Warning: Make sure that you store the pre-Release, 6.0(2)U6(3)’s configuration file.

For more information, see the Cisco Nexus 3000 Series NX-OS Software Upgrade and Downgrade Guide, Release 7.x.

6.0(2)U6(2) or earlier

7.0(3)I2(1)

First, upgrade to Cisco NX-OS Release 6.0(2)U6(3) or a later release.

Note: A Cisco Nexus 3048 switch requires an additional step when you upgrade from a software version older than Cisco NX-OS 6.0(2)U6(2), otherwise the switch can fail to boot. You must first upgrade the switch to Cisco NX-OS Release 6.0(2)U6(2), then to Cisco NX-OS Release 6.0(2)U6(3), and finally to Cisco NX-OS Release 7.0(3)I2(1).

Install all and fast reload are the only upgrade methods supported because of a BIOS upgrade requirement.

For more information, see the Cisco Nexus 3000 Series NX-OS Software Upgrade and Downgrade Guide, Release 7.x.

Downgrading to Release 6.0(2)U6(3) from Release 7.0(3)I2(1)

Downgrading from Release 7.0(3)I2(1)  to Release 6.0(2)U6(3) with configuration is not officially supported via install all. To downgrade to Release 6.0(2)U6(3) from Release 7.0(3)I2(1) with configuration, two reloads are required, one for boot into Release 6.0(2)U6(3) with write-erase and second for applying the new configuration. To avoid multiple reloads, the no-save option is supported during install all kickstart <img> system <img.sys> in Release 7.0(3)I2(1). Use the CLI option no-save for the downgrade scenario to Release 6.0(2)U6(3) that skips the copy r s process that the installer does.

Complete the following steps to downgrade to Release 6.0(2)U6(3) from Release 7.0(3)I2(1) and to avoid two reloads:

1.       Enter the command: write erase

2.       Enter the command: write erase boot

3.       Enter the command: copy <Release 6.0(2)U6(3) -config> startup-config

4.       Enter the command:  install all kickstart <img.kick> system <img.sys> no-save  bios-force

5.       The ASCII-replay of Release 6.0(2)U6(3)  configuration brings the switch up with the desired configuration and Release 6.0(2)U6(3)  image.

Warning: Make sure that you store the pre-Release, 6.0(2)U6(3)’s configuration file.

Breakout ports

The breakout ports are in administratively enabled state after the breakout of the ports into 4x10G mode or the breakin of the ports into 40G mode. On upgrade from the earlier releases, the configuration restored takes care of restoring the appropriate administrative state of the ports.

Cisco Nexus 3000 Series NX-OS Interfaces Configuration Guide

Chapter 2: Configuring Layer 2 Interfaces

Inband and management interfaces

Two network namespaces are now used for interface management: management and default. The management network namespace houses the eth1 link.

Any standard Linux command can be used on these namespaces through the ip netns exec management linux_command.

All inband and management interfaces to the Linux userspace are exposed as network interfaces. Also, network interfaces from Linux has changed.

Earlier software releases of Nexus 3K had the following Ethernet interfaces from linux as seen from the bash-shell:

■        eth1 (management)

■        eth3 (inband-low)

■        eth4(inband-hi)

Release 7.0(3)|2(1) is a combined image with N9K and N3k. This image consists of a combined supervisor image, and a pseudo line-card image on single RU TOR boxes like N3K. It has the following Ethernet interfaces as seen from the bash-shell:

■        eth0 - The eth0 and eth6 interfaces are Ethernet Out-of-Band Channel (EOBC) interfaces on the supervisor card, which is a connection between all cards on the switch for management purposes such as system messages, software download, etc. Note that this is not the management port. On N3k we only have the eth0 interface.

■        eth1 - The management interface that gets connected to the management LAN.

■        eth2 - eth2 and eth3 are the embedded packet capture (EPC) interfaces. eth2 is connected to Sup0, and eth3 is connected to Sup1 (since we have redundant supervisors). Since N3K does not have a Sup1, eth2 is the active EPC interface. Completely decoded packets can be seen with ethanalyzer on these interfaces

■        ps-eobc – This is a pseudo interface that acts as a mux between eth0 and eth6, depending on which supervisor card is present. For the users of ps-eobc, this is the logical EOBC interface. All traffic from linecard system-messages, software download, etc., come here first then get copied onto eth0 and eth6 interfaces. On N3K we only have eth0 interface.

■        ps-inb - This is a pseudo interface that is a mux between eth2 and eth3, depending on which supervisor card is present. For users of ps-inb, this is the logical inband interface. Ethanalyzer can be used directly with ps-inb, but it will not show you the packet decoded.

■        veobc – This is the virtual Ethernet Out-of-Band Channel interface. This is a layer above ps-eobc and ps-inb needed for the FEX feature, where EOBC is a tunnel over inband. N3K does not use this, but the interface is created for common image management between N9k and N3k.

■        sflow -  sflow packets come to this interface.

Layer 3 licensing

The Cisco Nexus 3000 has a BASE license in N3K mode that provides:

■        Static routing

■        RIPv2

■        EIGRP stub

■        OSPFv2 (limited routes)

■        PIMv2 (sparse mode)

In N9K mode, the N9K licensing model is assumed, and it will not have this license. When a routing protocol gets enabled, syslog messages will be thrown.

Cisco Nexus 3000 Series NX-OS Licensing Guide

Loopback interface

In the previous release, the loopback interface that is used to configure RP in multicast may or may not have the ip pim sparse-mode configuration. Beginning with Release 7.0(3)I2(1), the loopback interface which is used as an RP in multicast must have the ip pim sparse-mode configuration.

Password strength-check

New password strength-check criteria that rejects simplistic passwords. This feature displays a message indicating the password is too simplistic/systematic.

For example:

switch(config)# username xyz password nbv12345

password is weak

Password should contain characters from at least three of the following classes: lower case letters, upper case letters, digits and special characters.

switch(config)# username  xyz password Nbv12345

password is weak

it is too simplistic/systematic

switch(config)#

Chapter 7: Configuring User Accounts and RBAC

PIM

The PIM_IGMP class-id is set on the port only when PIM is enabled. Since there is no need to punt IGMP packets to the CPU on the Layer 3 ports when PIM is not enabled, you have to configure feature pim and enable PIM on the port to get the packets on the copp-s-igmp queue.

Chapter 12: Configuring Control Plane Policing

Priority levels

Prior to Release 7.0(3)I2(1), only priority level 1 was supported in the pmap configuration. Starting with Release 7.0(3)I2(1), you can configure priority levels 2 and 3 in the pmap configuration. Note that 3000 series switches support only one priority level in Hardware. Release 7.0(3)I2(1) supports only the functionality for priority level 1 for Cisco Nexus 3000 Series platforms even though both priority level 2 and 3 are allowed in the pmap configuration in the Cisco Nexus 3000 Series platforms. Cisco Nexus 3100 Series platforms support priority level 1, 2, 3 with functionality perspective.

Syslog message (Hash collision)

A new syslog message has been added that includes the MAC collision events and the other details such as the source MAC address, the VLAN, and the internal port number information.

Example: 2015 Aug 26 06:20:37 switch%-SLOT1-5-BCM_L2_HASH_COLLISION: L2 ENTRY unit=0 mac=00:11:11:f7:46:40 vlan=1998 port=0x0800082e

VXLAN multicast encapsulation path.

The VXLAN multicast encapsulation path has duplicate members of the vPC peer-link on vPC peers. This design has been adopted to support anycast RP and service orphan traffic. For all the access side traffic, now, two copies of a packet are sent over the vPC peer-link on the multicast path: one native and one VXLAN header encapsulated.

show ip pim rp

In earlier releases, the PIM-process is always running and show ip pim rp is handled properly. Beginning in Release 7.0(3)I2(1), if no interfaces are PIM-enabled, this command will throw “process is not running” errors.

Section: show ip pim rp

show logging onboard

While the induced errors are corrected on the switches, the log messages that notify the corrections stop after hitting a threshold (usually after 15 or 19 corrections). Also, an extra message gets printed when the parity error is injected.
