efa inventory device interface set-mtu

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

Syntax

Parameters

--if-type eth: Specifies that the interface type is Ethernet, which is the default setting.
--if-name if-list: Specifies a comma-separated list of interface names. For example: 0/50-52,0/45.
--ip device-ip: Specifies a comma-separated range of device IP addresses. For example: 10.1.1.13,10.1.1.50,10.1.1.101.
--ip-mtu int ip-mtu-value: Specifies the global IP MTU value on a device. For SLX IPv4, valid values range from 1300 through 9194.
--ipv6-mtu ipv6-mtu-value: Specifies the global IPv6 MTU on a device. For SLX IPv4 or IPv6, valid values range from 1300 through 9194.
--mtu int mtu-value: Specifies the global Layer 2 MTU on a device. For SLX-OS 21.1 and later, valid values range from 1500 through 9216. For other SLX-OS versions, valid values range from 1548 through 9216.

Usage Guidelines

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

The configuration you set is persisted.

DRC and idempotency are supported.

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
