10/100M mode
To configure IPG on a Gbps Ethernet port for 10/100M mode, enter the following command.
device(config)# interface ethernet 7/1
device(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.
device(config)# interface ethernet 7/1
device(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.
device(config)# interface ethernet 9/1
device(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.
IPG on FastIron Stackable devices
On FCX and ICX devices, you can configure an IPG for each port. An IPG is a configurable time delay
between successive data packets.
You can configure an IPG with a range from 48-120 bit times in multiples of 8, with a default of 96. The
IPG may be set from either the interface configuration level or the multiple interface level.
IPG configuration notes
• The CLI syntax for IPG differs on FastIron Stackabledevices compared to FastIron X Series
devices. This section describes the configuration procedures for FastIron Stackabledevices. For
FastIron X Series devices, refer to Interpacket Gap (IPG) on a FastIron X Series switch on page 71.
• 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.
