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.
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.
device(config)# interface ethernet 0/1/21
device(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.
device(config)# interface ethernet 0/1/11 ethernet 0/1/14 to 0/1/17
device(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.
device# show interfaces ethernet 0/1/21
GigabitEthernet 0/1/21 is up, line protocol is up
Port up for 40 seconds

Inter-Packet Gap (IPG) is 112 bit times
IP MTU 10222 bytes
300 second input rate: 0 bits/sec, 0 packets/sec, 0.00% utilization
300 second output rate: 248 bits/sec, 0 packets/sec, 0.00% utilization
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 multicasts, 0 unicasts
0 input errors, 0 CRC, 0 frame, 0 ignored
0 runts, 0 giants
80 packets output, 5120 bytes, 0 underruns
Transmitted 0 broadcasts, 80 multicasts, 0 unicasts
0 output errors, 0 collisions
Enabling and disabling support for 100BaseTX
For FastIron X Series devices, you can configure a 1000Base-TX SFP (part number E1MG-TX) to
operate at a speed of 100 Mbps. To do so, enter the 100-tx command at the Interface level of the CLI.
device(config-if-e1000-11)# 100-tx
