pre-Version
6.1.1.0
Introduced for E-Series
Usage
Information
For 1-Gigabit Ethernet interfaces only.
NOTE: This command is an EtherScale-only command.
ipg (10 Gigabit Ethernet interfaces)
Set the inter-packet gap for traffic on 10–Gigabit Ethernet interface.
E-Series
Syntax
ipg {ieee-802.3ae | shrink}
To return to the default of averaging the IPG, use the no ipg {shrink |
ieee-802.3ae} command.
Parameters
ieee-802.3ae Enter the keyword ieee-802.3ae to set the IPG to 12 (12-15) bytes
