efa inventory device interface set-mtu

Configures the MTU (maximum transmission unit) at the physical port level for Layer 2, IPv4, and IPv6.

Syntax

efa inventory device interface set-mtu [--ip --if-type eth --if-name --mtu int --ip-mtu int --ipv6-mtu int32 --fabric --help]

Parameters

--ip: Specifies a comma-separated range of device IP addresses.
--if-type eth: Specifies that the interface type is Ethernet, which is the default setting.
--if-name: Specifies a comma-separated list of interface names.
--mtu int: Specifies the global Layer 2 MTU on a device. For SLX-OS 20.1.1 and later, valid values range from 1500 through 9216. For other SLX-OS versions, valid values range from1548 through 9216.
--ip-mtu int: Specifies the global IP MTU value on device. For SLX IPV4/IPV6, valid values range from 1300 through 9194.
--ipv6-mtu int: Specifies the global IPv6 MTU on a device. For SLX IPV4/IPV6, valid values range from 1300 through 9194.
--fabric: Specifies a Fabric name.
--help: Displays help for set-mtu.

Usage Guidelines

In SLX-OS, you can use the show interface ethernet command to see the MTU configuration for an interface.

Examples

This example configures the MTU on one device.

efa inventory device interface set-mtu --ip 10.25.225.167 --if-name 0/20-22   
--mtu 2000 --ip-mtu 2000 --ipv6-mtu 3000
