By providing a software-only solution, Cumulus Linux is enabling disaggregation of data center switches akin to the x86 server hardware/software disaggregation. Cisco Nexus 3000 Series. and FEC on swp1, run: To view the FEC setting on an interface, run: This section provides troublshooting tips. MTU is the only interface setting that you must set manually. In the case where a manufacturer stops selling a switch (known as End of Sale, or EoS), Cumulus Networks will continue to support that switch, as per the policy defined here. Do not These commands create the following code snippet in the /etc/network/interfaces file: You can specify both IPv4 and IPv6 addresses for the same interface. limitation. Break out 40G switch ports into four separate 10G ports for use with breakout cables. A non-zero value indicates bit errors. Find the best fit for your organization by comparing feature ratings, customer experience ratings, pros and cons, and reviewer demographics. Cumulus Linux is based on the Debian distribution. When you run ifup on a logical interface (like a bridge, bond or VLAN interface), if the ifup results in the creation of the logical interface, it implicitly tries to execute on the interface’s upper (or parent) interfaces as well. On this hardware, several Network Operating Systems from different vendors can be installed, for example: Cumulus Linux Big Switch Networks Switch Light OS Dell OS9 Dell OS10 (in the Installing a new NOS using DHCP and HTTP via ONIE: In this example, we will use OS10 as the NOS and the Dell S4048-ON as the hardware platform. Avoid using apostrophes or non-ASCII characters in the hostname. For a global policy to set MTU, create a policy document (called mtu.json here) like the following: After making the edits to the policy file above, apply the changed policy with the ifreload -a command. can specify a policy for all interfaces on a switch, or tailor custom The following article is a how-to use a QSFP-to-SFP adapter with Cumulus Linux, however, other vendors are really similar. There are additional FEC options for Cumulus Linux configuration: You cannot set RS FEC on any Trident II switch with either NCLU or by 64-port Broadcom switches with the Tomahawk2 ASIC have a limit of 128 total logical ports. example shows the default settings in the /etc/cumulus/ports.conf file If you are working with VXLANs, the MTU for a virtual network interface (VNI) must be 50 bytes smaller than the MTU of the physical interfaces on the switch, as those 50 bytes are required for various headers and other data. WARNING: This will wipe out all system data. neighbor without FEC. order; for example, swp1, swp2, swp3, and swp4, unless a particular core grouping is specified in the /etc/cumulus/ports.conf file. Configuration. 802.3by 25G DAC specification). ethtool or ifreload to change the speed to 10G or 1G returns an error (and a return code of 255). For 100G DACs, most manufacturers use the 0x0Bh 100GBASE-CR4 or The hostname identifies the switch; make sure you configure the hostname to be unique and descriptive. The following examples show the output of ports in admin down, down, and up modes: To enable a port, run the ip link set up command. error occurs while removing and reinserting QSFP module. If you do decide to disable auto-negotiation, be aware of the following: For 1000BASE-T RJ-45 SFP adapters, auto-negotiation is automatically 1.

We again have Broadcom options with the S5296F-ON listed. need to specify link duplex if you want half-duplex mode. install a Debian package on ifup of swp1, even though it is To run with dependents when you specify the interface list, use the --with-depends option. to its capabilities. cable as follows. RS FEC is the expected setting for 100G However, you can disable FEC if necessary, which forces the firmware to not try any FEC options. 10M or 100M speeds are possible with auto-negotiation OFF on both sides. A Spectrum switch enables FEC automatically when it powers up; that is, and 51/52 are not supported natively at 200G speeds. To bring up the physical connection to an interface or apply changes to an existing interface, run the sudo ifup command. the link comes up. When you run ifup and ifdown There is no need to specify MTU on the slave interfaces. When in doubt, consult the manufacturer directly to determine the cable Cumulus Linux: Useful Commands; Layer 1 and Switch Port Attributes - Cumulus Linux; Cumulus Linux Initial Configuration for Mellanox NEO Provisioning . restarting `switchd` 1. The duplex mode setting defaults to full. cumulus@switch:~$ net show interface | grep UP. Native Security: From OpenSSH to authentication, Cumulus Linux keeps your switches secure. If you need a different MTU on the bond, set it on the bond interface, as this ensures the slave interfaces pick it up. So, in the above case, 10.1.1.1 is actually 10.1.1.1/32. You cannot purge existing addresses on interfaces with multiple iface stanzas. These commands break out swp1 into four 25G interfaces in the /etc/cumulus/ports.conf file and create four interfaces in the /etc/network/interfaces file: When you commit your change, switchd restarts to apply the changes. enable a simpler configuration, Cumulus Linux allows you to configure ONIE switch_asic : qemu ONIE skip_ethmgmt_macs: yes ONIE grub_image_name: grubx64.efi ONIE uefi_boot_loader: grubx64.efi ONIE uefi_arch : x64 history: Displays CLI command history.
