Configuring Duplex Mode

The interfaces duplex
or all ports on a switch (slot) to full (full duplex mode, which is the default on fiber ports), half (half
duplex mode), and auto (autonegotiation, which is the default on copper ports). (The Auto option causes
the switch to advertise all available duplex modes (half/full/both) for the port during autonegotiation.) In
full duplex mode, the interface transmits and receives data simultaneously. In half duplex mode, the inter-
face can only transmit or receive data at a given time.
Note. The Auto option sets both the duplex mode and line speed settings to autonegotiation.
In order to set up a speed and duplex on a port autonegotiation should be disabled.
-> interfaces 2 autoneg disable
To configure the duplex mode on an entire slot, enter interfaces followed by the slot number, duplex, and
the desired duplex setting (auto, full, or half). For example, to set the duplex mode on slot 2 to full, enter:
-> interfaces 2 duplex full
To configure the duplex mode on a single port, enter interfaces followed by the slot number, a slash (/),
the port number, duplex, and the desired duplex setting (auto, full, or half). For example, to set the
duplex mode on port 3 on slot 2 to full, enter:
-> interfaces 2/3 duplex full
To configure the duplex mode on a range of ports, enter interfaces followed by the slot number, a slash (/
), the first port number, a hyphen (-), the last port number, duplex, and the desired duplex setting (auto,
full, or half). For example, to set the duplex mode on ports 1 through 3 on slot 2 to full, enter:
-> interfaces 2/1-3 duplex full

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.
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 20 on slot 2 to 10 bytes, enter:
