Permitted Values
Description
speed-and-
duplex state
Variable
'10hd'
'10fd'
'100hd'
'100fd'
'1000fd'
‘10000fd’
This parameter sets the maximum speed
and the duplex state of the interface. For
RJ-45 interfaces, any of the permitted
values except 10000fd can be configured.
For SFP interfaces, only '1000fd' is
supported.
Note:
In relase 10.6, only Ethernet 7
(SFP+) is supported. In release 10.9,
Ethernet Slot 1, Ports 4 through 7 are also
supported.
Note
To use an SFP+ interface in 10G mode, the third-party switch must be running Pause Frame Flow
Control, as defined in IEEE 802.3x. It is also recommended to configure shapers on the third-party
switch so as to limit the packet flow from the switch to the PTP 850E unit to 2.5 Gbps.
After changing the speed of an SFP+ interface to or from 10000fd, you must reset the unit in order
for the change to take effect.
Configuring an Interface’s Auto Negotiation State (CLI)
To configure an Ethernet interface’s auto-negotiation state, go to interface view for the interface and enter the
following command:
eth type eth [x/x]>autoneg state set <autoneg state>

Description
autoneg state Variable
On
off
Enables or disables auto-negotiation on
the physical interface.
The following command enables auto negotiation for GbE 2:
eth type eth [1/2]>autoneg state set on
Configuring an Interface’s IFG (CLI)
The IFG attribute represents the physical port Inter-frame gap. Although you can modify the IFG field length, it is
strongly recommended not to modify the default value of 12 bytes without a thorough understanding of how the
modification will impact traffic.
To configure an Ethernet interface’s IFG, go to interface view for the interface and enter the following command:
