Basic port parameter configuration
IPG configuration notes
• The CLI syntax for IPG differs on FastIron Stackable devices compared to FastIron X Series
devices. This section describes the configuration procedures for FastIron Stackable devices.
For FastIron X Series devices, refer to “Interpacket Gap (IPG) on a FastIron X Series switch” on
page 53.
• When an IPG is applied to a trunk group, it applies to all ports in the trunk group. When you are
creating a new trunk group, the IPG setting on the primary port is automatically applied to the
secondary ports.
• This feature is supported on 10/100/1000M ports.
Configuring IPG on a 10/100/1000M port
To configure an IPG of 112 on Ethernet interface 0/1/21, for example, enter the following
command.
Brocade(config)# interface ethernet 0/1/21
Brocade(config-if-e1000-0/1/21)# ipg 112
For multiple interface levels, to configure IPG for ports 0/1/11 and 0/1/14 through 0/1/17, enter
the following commands.
Brocade(config)# interface ethernet 0/1/11 ethernet 0/1/14 to 0/1/17
Brocade(config-mif-0/1/11,0/1/14-0/1/17)# ipg 104
Syntax: [no] ipg <value>
For value, enter a number in the range from 48-120 bit times in multiples of 8. The default is 96.
As a result of the above configuration, the output from the show interface Ethernet 0/1/21
command is as follows.
Brocade# show interfaces ethernet 0/1/21
