Enabling Jumbo Frames in a Solaris Environment

This section describes how to enable jumbo frames in both a SPARC and an x86 environment.

▼To Enable Jumbo Frames in a Solaris Environment Using nxge.conf

1. Enable Jumbo Frames for a port using the nxge.conf file. For example,

name = "pciex108e,abcd" parent = "/pci@780/pci@0/pci@8/network@0" unit-address = "0"

accept-jumbo=1;

2.Reboot the system:

%boot -r

3.Set the maximum MTU for maximum performance:

#ifconfig nxge mtu 9194

▼To Check Layer 2 Configuration

●View the maximum transmission unit (MTU) configuration of an nxge instance at any time with the kstat command.

#kstat nxge:0 grep mac_mtu

The kstat mac_mtu variable represents the complete size of the Ethernet frame, which includes the Ethernet header, maximum payload, and crc. This value should be equal to or less than the MTU configured on the switch.
