Configuring Inter-Frame Gap Values - Alcatel OmniSwitch 6624 Network Configuration Manual

Configuring Ethernet Ports
To enable or disable a single port enter interfaces followed by the slot number, a slash (/), the port
number, admin, and the desired administrative setting (either up or down). For example, to administra-
tively disable port 3 on slot 2 enter:
-> interfaces 2/3 admin down
To enable or disable a range of ports enter interfaces followed by the slot number, a slash (/), the first port
number, a hyphen (-), the last port number, admin, and the desired administrative setting (either up or
down). For example, to administratively disable ports 1 through 3 on slot 2 enter:
-> interfaces 2/1-3 admin down
As an option, you can document the interface type by entering ethernet, fastethernet, or gigaethernet
before the slot number. For example, to administratively disable port 3 on slot 2 and document the port as
Fast Ethernet:
-> interfaces fastethernet 2/3 admin down

Configuring Inter-frame Gap Values

Inter-frame gap is a measure of the minimum idle time between the end of one frame transmission and the
beginning of another. By default, the inter-frame gap is 12 bytes. The
to configure the inter-frame gap value (in bytes) on a specific port, a range of ports, or all ports on a
switch (slot). Values for this command range from 9 to 12 bytes.
Note. This command is only valid on Gigabit ports. Gigabit Ethernet is supported only on ports 49
through 51 on the OmniSwitch 6648 and ports 25 through 28 on the OmniSwitch 6624 and 6600-U24
when Gigabit Ethernet expansion modules are installed.
To configure the inter-frame gap on an entire slot enter interfaces, followed by the slot number, ifg, and
the desired inter-frame gap value. For example, to set the inter-frame gap value on slot 2 to 10 bytes enter:
-> interfaces 2 ifg 10
To configure the inter-frame gap on a single port enter interfaces, followed by the slot number, a slash (/),
the port number, ifg, and the desired inter-frame gap value. For example, to set the inter-frame gap value
on port 52 on slot 2 to 10 bytes enter:
-> interfaces 2/52 ifg 10
To configure the inter-frame gap on a range of ports enter interfaces, followed by the slot number, a slash
(/), the first port number, a hyphen (-), the last port number, ifg, and the desired inter-frame gap value. For
example, to set the inter-frame gap value on ports 51 through 52 on slot 2 to 10 bytes enter:
-> interfaces 2/51-52 ifg 10
As an option, you can document the interface type by entering ethernet, fastethernet, or gigaethernet
before the slot number. For example, to set the inter-frame gap value on port 52 on slot 2 to 10 bytes and
document the port as Gigabit Ethernet enter:
-> interfaces gigaethernet 2/52 ifg 10
