2.3.4
Duplex Operation
The Supermicro F3548 switch doesn’t support half-duplex operation on its physical interfaces.
2.3.5
MTU
The default maximum transmission unit (MTU) size for frames received and transmitted is 1500 bytes. The
MTU size can be increased for an interface.
Follow the steps below to configure the interface MTU.
Step Command
Description
Step 1 configure terminal
Enters the configuration mode
Step 2 interface
<
interface-type
><
interface-id
>
or
interface range
<
interface-type><interface-id> ….
Enters the interface configuration
mode.
interface-type – may be any of the
following:
fx-ethernet – fx
cx-ethernet – cxport-channel
interface-id is in slot/port format for all
physical interfaces.
To configure multiple interfaces, use
the “interface range …” command. To
provide a range use a hyphen (-)
between the start and end interface
numbers. E.g.: int range fx 0/1-10
To provide multiple interfaces or
ranges, separate with a comma (,).
E.g.: int range fx 0/1-10, fx 0/20
If multiple interfaces are provided, the
next step will perform the particular
configuration on all these interfaces.
Step 3 mtu<frame-size(1500-9216)>
Configure interface MTU in the range
1500-9216.
Step 4 End
Exits the configuration mode.
Step 5 show interface status
Displays the interface configuration.
Step 6 write startup-config
Optional step – saves this configuration
to be part of startup configuration.
The “no mtu” command restores the interface MTU to its default of 1500 bytes.
To change the MTU for all the interfaces, the “system mtu” command can be used.
