Ethernet Port Configuration Commands 51
■ The slot number is a number in the range 0 to 6 (the Fabric slot is 0).
■ The subslot number is set to 0.
■ The port number is a number in the range 1 to 8 (on an 8-port Gigabit
module),
1 to 24 (on a 24-port 100BASE-FX module), or 1 to 48 (on a 48-port
10/100/BASE-TX modules).
The M-Ethernet interface is always set to 0/0/0.
You can use the interface_name at this command. This is made up of
interface_type and interface_number parameters combined as a single
parameter, for example Ethernet0/0/1.
Description
Use the command interface interface_type interface_number to enter the
interface of the specified port.
If you want to configure the parameters of an Ethernet port, you must first use
this command to enter the Ethernet port view.
Example
To enter the interface for port “Ethernet1/0/1”, enter the following:
[SW7700]interface ethernet1/0/1
[SW7700 ethernet1/0/1]
jumboframe Syntax
jumboframe enable
undo jumboframe enable
View
Ethernet port view
Parameter
enable: Enter to permit jumbo frames to pass through the current Ethernet port.
Description
■ Use the jumboframe enable command to allow “jumbo” frames through the
specified Ethernet port. Jumbo frames are frames of up to 9KB in size.
■ Use the undo jumboframe enable command to prevent jumbo frames from
passing through an Ethernet port. By default, jumbo frames are disabled.
Jumbo frames are only allowed for packets with an ether type field set to
“Ethernet Type II”. Caution should be used when using jumbo frames in a
network as any device that does not support these packets will automatically filter
thoese packets.
Packets up to 1536 bytes, including the IEEE 802.1Q tagging are always allowed
to pass through Ethernet ports.
