34 iSCSI Cluster Setup for EqualLogic Storage Systems
For example:
# ethtool -a eth2
Pause parameters for eth2:
Autonegotiate: on
RX: on
TX: on
This example shows that Flow Control is already turned on. If it is not turned
on, use the following command to turn on Flow Control:
# ethtool -A <interface> rx on tx on
Jumbo Frame is configured in the /etc/sysconfig/network-scripts/ifcfg-
<interface> scripts, by adding the MTU="<mtu-value>" parameter.
The example below shows the MTU set to 9000.
# cat /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
HWADDR=00:15:17:80:43:50
ONBOOT=yes
TYPE=Ethernet
BOOTPROTO=none
IPADDR=10.16.7.125
NETMASK=255.255.255.0
USERCTL=no
MTU=9000
Verify the Jumbo Frame setting using the ifconfig command:
$ ifconfig eth2
eth2 Link encap:Ethernet HWaddr
