Basic port parameter configuration
IPG on a FastIron X series switch configuration notes
• The CLI syntax for IPG differs on FastIron X Series devices compared to FastIron Stackable
devices. This section describes the configuration procedures for FastIron X Series devices. For
FastIron Stackable devices, refer to “IPG on FastIron Stackable devices” on page 55.
• IPG configuration commands are based on "port regions". All ports within the same port region
should have the same IPG configuration. If a port region contains two or more ports, changes
to the IPG configuration for one port are applied to all ports in the same port region. When you
enter a value for IPG, the CLI displays the ports to which the IPG configuration is applied.
Example
Brocade(config-if-e1000-7/1)# ipg-gmii 120
IPG 120(112) has been successfully configured for ports 7/1 to 7/12
• When you enter a value for IPG, the device applies the closest valid IPG value for the port mode
to the interface. For example, if you specify 120 for a 1 Gbps Ethernet port in 1 Gbps mode, the
device assigns 112 as the closest valid IPG value to program into hardware.
Configuring IPG on a Gbps Ethernet port
On a Gbps Ethernet port, you can configure IPG for 10/100 mode and for Gbps Ethernet mode.
10/100M mode
To configure IPG on a Gbps Ethernet port for 10/100M mode, enter the following command.
Brocade(config)# interface ethernet 7/1
Brocade(config-if-e1000-7/1)# ipg-mii 120
IPG 120(120) has been successfully configured for ports 7/1 to 7/12
Syntax: [no] ipg-mii <bit time>
Enter 12-124 for <bit time>. The default is 96 bit time.
1G mode
To configure IPG on a Gbps Ethernet port for 1-Gbps Ethernet mode, enter commands such as the
following.
Brocade(config)# interface ethernet 7/1
Brocade(config-if-e1000-7/1)# ipg-gmii 120
IPG 120(112) has been successfully configured for ports 0/7/1 to 7/12
Syntax: [no] ipg-gmii <bit time>
Enter 48 - 112 for <bit time>. The default is 96 bit time.
Configuring IPG on a 10 Gbps Ethernet interface
To configure IPG on a 10 Gbps Ethernet interface, enter commands such as the following.
Brocade(config)# interface ethernet 9/1
Brocade(config-if-e10000-9/1)# ipg-xgmii 120
IPG 120(128) has been successfully configured for port 9/1
Syntax: [no] ipg-xgmii <bit time>
Enter 96-192 for <bit time>. The default is 96 bit time.
