Enabling Jumbo Frames on the Solaris guest operating system (2012445)

  • 15 Ratings

Purpose

This article provides information on enabling Jumbo Frames on the Solaris guest operating system.

Resolution

To utilise Jumbo Frames on Solaris, you must meet these prerequisites:
  • Solaris 10 U4 (32bit or 64bit) or later
  • VMXNET 3 virtual network adapter
  • ESXi 5.0
  • VMware Tools installed and running in the virtual machine
  • Jumbo Frames configured on all interconnecting network points from the virtual machine to its desired target
To use Jumbo Frames on Solaris:
 
Note: The first virtual NIC is usually identified as /dev/vmxnet3s0. If your identifier differs, substitute it appropriately in these commands.

  1. Enable Jumbo Frames using this command:

    # ndd -set /dev/vmxnet3s0 accept-jumbo 1

  2. Set the MTU on the adapter to 9000 using this command:

    # ifconfig vmxnet3s0 mtu 9000
You can test the settings by pinging to and from the machine with 9000 byte packets.

To test from a remote client, run this command:

# ping -s 9000 IP_of_Solaris_machine

To test from the Solaris machine, run this command:

# ping -s IP_of_another_machine 9000 4
