MLNX-GW Routing Overview

The following pages provide information on configuring IP routing (L3) protocols and features.

Ethernet Interfaces

show interfaces ethernet

	show interfaces ethernet [<interface>] Displays information on Ethernet interfaces. If the interface is not specified, then the command prints all the Ethernet interfaces.
Syntax Description	Interface	Device/port (e.g., 1/2).
Default	N/A
Configuration Mode	Any command mode
History	8.0.0100
	8.0.1610	Added notes
	8.0.3000	Updated example to reflect port channel field
Example	gateway (config) # show interfaces ethernet 1/2 Eth1/2: Admin state : Enabled Operational state: Up Description : Mac address : ec:01:8a:ad:28:ef MTU : 1500 bytes Fec : auto Supported speeds : 100G 200G Actual speed : 200G Auto-negotiation : Enabled Port channel : Po1 Rx: packets : 1896 bytes : 403944 error packets: 0 Tx: packets : 29688 bytes : 2182632 error packets: 0
Related Commands	show interfaces ib show interfaces ethernet port-channel
Notes	For version 8.0.0100, the only valid interface is “1/2” If the peer IB port is down, the message below will appear in brackets as part of the Operational State of the Ethernet port: "IB port down". The peer port of the Ethernet port is the IB port on the same device, for example "1/1" is the peer of "1/2". If LAG is not configured correctly on the ethernet router, the message below will appear in brackets as part of the Operational State of the Ethernet port: "Suspended". This message has higher priority than the "IB port down" message. If an Ethernet port channel is down, the message below will appear on brackets as part of the Operational State of the Ethernet port: "inherited down". This message has higher priority then the "IB port down" and "Suspended" messages.

show interfaces ethernet port-channel

	show interfaces ethernet port-channel [<port-channel>] Displays information on Ethernet port-channel interfaces.If the port-channel number is not specified, then the command prints all the Ethernet port-channels.

History	8.0.0100
Example	gateway (config) # interface ethernet port-channel 1 shutdown
Related Commands	show interfaces ethernet port-channel interface ethernet shutdown
Notes	For version 8.0.0100, the command will not have impact—to shut down the ethernet interface use “interface ethernet shutdown” For versions 8.0.01xx and 8.0.16xx, the only valid port-channel number is 1

interface ethernet port-channel

Example	gateway (config) # interface ethernet port-channel 1 description
Related Commands	show interfaces ethernet port-channel
Notes	For versions 8.0.01xx and 8.0.16xx, the only valid port-channel number is 1

interface ethernet port-channel mtu

	interface ethernet port-channel <port-channel> mtu <mtu> no interface ethernet port-channel <port-channel> mtu Configures the Maximum Transmission Unit (MTU) frame size for the interface. The no form of the command resets the MTU to its default value.

interface ethernet port-channel ip address

	interface ethernet port-channel <port-channel> ip address <ip-address> <mask> no interface ethernet port-channel <port-channel> ip address [<ip-address>] Enters user-defined IPv4 address for the interface. The no form of the command removes the specified IPv4 address. If no address is specified, then all IPv4 addresses of this interface are removed.

	Ip-address	IPv4 address
	mask	There are two possible ways to the mask: /length (i.e. /24) Network address (i.e. 255.255.255.0) The mask length may be configured without a space (i.e. <ipv4-address>/<length>)
Default	N/A
Configuration Mode	config

History	8.0.1600	Added note
Example	gateway (config) # interface ethernet port-channel 1 ip address 1.1.1.1/24
Related Commands	show interfaces ethernet port-channel
Notes	For versions 8.0.01xx and 8.0.16xx, the only valid port-channel number is 1 In version 8.0.1600, configuring IP on IB port-channel configures additional IP on one of the physical IB interfaces which is formed by incrementing the passed IP address by one. For example, running the command "interface ib port-channel 1 ip address 1.1.1.1/24" will configure the IP addresses "1.1.1.1" and "1.1.1.2" on one of the physical IB interfaces.

Notes	For version 8.0.0100, the only valid interface is “1/1” If the peer Ethernet port is down, the message below will appear in brackets as part of the Operational State of the IB port: "ETH port down". The peer port of the IB port is the Ethernet port on the same device, for example "1/2" is the peer of "1/1". MTU shows the actual L2 MTU configured in the subnet. If the interface is not specified, then the command prints all the Infiniband interfaces includes PKEYs.

show interfaces ib port-channel

	show interfaces ib port-channel [<port-channel>] Displays information on Infiniband port-channel interfaces. If the port-channel number is not specified, then the command prints all the Infiniband port-channels.

Related Commands	show interfaces ib show interfaces ethernet port-channel interface ib port-channel ip address interface ib port-channel virtual ip address show interfaces ib port-channel counters aggregate
Notes	For versions 8.0.01xx to 8.0.23xx, the only valid port-channel number is 1 If IP is not configured, then the IPv4 and Broadcast addresses will not be shown When no PKEY is specified, the operation is applied on the default PKEY ( 0x7FFF) This show command takes data from the Linux and should reflect the IP addresses currently installed. In case one address was not installed, N/A will be displayed. One of the following reasons will be displayed in brackets: IPv4 and Virtual IPv4 should be configured to different values IPv4 and Virtual IPv4 should be configured to be on the same subnet If the interface is not specified, then the command prints all the Infiniband interfaces includes PKEYs. This command doesn't show counters. It is possible to debug via counters using counters of InfiniBand interfaces shown as part of the command "show interface ib <device>/<port>" or using the counters shown as part of the command "show interface ib port-channel * counters aggregate" RX/TX counters will appear in the output until a non-default pkey is configured

show interfaces ib port-channel counters aggregate

	show interfaces ib port-channel * counters aggregate Aggregated counters of all IB interfaces in the system
Syntax Description	N/A
Default	N/A
Configuration Mode	Any command mode
History	8.1.3000
Examples	`gateway (config) # show interfaces ib port-channel 1 counters aggregate` `Rx:` `packets : 388` `bytes : 38800` `error packets: 0` `Tx:` `packets : 29` `bytes : 1740` `error packets: 0`

	-p	Uses destination port. It is an initial value for the UDP destination port (incremented by each probe, default is 33434), for the ICMP seq number (incremented as well, default from 1), and the constant destination port for TCP tries (default is 80).
	-t	Sets the TOS (IPv4 type of service) or TC (IPv6 traffic class) value for outgoing packets
	-l	Uses specified flow_label for IPv6 packets

VF Hashing Policy

gw vf-hash-policy

	gw vf-hash-policy * [force] no gw vf-hash-policy * [force] Configure the policy of the VF hash function. The no form of the command resets the policy to the default policy.
