VxFlex Network Deployment Guide using Dell EMC Networking 25GbE switches and OS10EE

To enable jumbo frames for the SVM, perform the following steps:

1. Run the

ifconfig

command to get the NIC information. The following is an example from an SVM

deployed in this solution, VxFlex-172.16.33.12:

VxFlex-172-16-33-12:~ #

ifconfig

In this example, eth1 and eth2 correspond to VxFlex Data Network 1 (subnet 172.16.34.0/24, VLAN

1634) and VxFlex Data Network 2 (subnet 172.16.35.0/24, VLAN 1635). Administrative access uses

Eth0.

2.

Using the interface name, edit the appropriate network configuration files, and append MTU value of

9000 to the end of the configuration. The following is an example for interface eth1:

VxFlex-172-16-33-12:~ #

vi /etc/sysconfig/network/ifcfg-eth1

DEVICE=eth1

STARTMODE=onboot

USERCONTROL=no

BOOTPROTO=static

NETMASK=255.255.255.0

IPADDR=172.16.34.12

MTU=9000
