1.3.4 MAC ADDRESS
Configures the physical address of the interface (MAC). The interface can adopt locally administered addresses, or
those given by the device manufacturer (universal administration). Through this command, only locally administrated
addresses are deemed valid. Entering 00:00:00:00:00:00 (default value) forces the router to use the address given
by the manufacturer for the interface. This last MAC address is used by default.
Example:
token-ring3/0 config>mac-address 50:84:c0:4c:84:4e
token-ring3/0 config>
1.3.5 NO
Sets the different parameters to their default values.

'Removes’ packets Number of MAC remove from the ring frames received by the interface. On receiv-
ing these, the interface removes itself from the ring.
Line errors Increases when a frame is repeated or copied, the Error Detected Indicator (EDI)
bit is 0 for the incoming frame and one of the following conditions is met:
a) A Token has a code violation.
b) A frame has a code violation between the start and end delimiters.
c) A Frame Check Sequence (FCS) error occurs.
ARI/FCI errors The ARI/FCI (Address Recognized Indicator/Frame Copied Indicator) Errors
counter increases if the interface receives either of the following:
a) An Active Monitor Present (AMP) MAC frame with the ARI/FCI bits equal to 0
and a Standby Monitor Present (SMP) MAC frame with the ARI/FCI bits equal to
0.
b) More than one SMP MAC frame with the ARI/FCI bits equal to 0, without an in-
tervening AMP MAC frame.
This condition indicates the upstream neighbor (from where frames are received)
is unable to activate the ARI/FCI bits.
Frame copy errors The interface, in receive/copy mode, recognizes a frame addressed to its specific
address but finds the Address Recognize Indicator (ARI) bits is not equal to 0.
This error indicates a possible line hit or duplicate address.
Lost frames The interface is in transmit mode and fails to receive the end of a transmitted
frame.
'Burst' errors The interface detects the absence of transitions for five half-bits times between the
start delimiter (SDEL) and the end delimiter (EDEL), or between the EDEL and the
SDEL.
Input drops The interface, in repeat mode, recognizes a frame addressed to it but has no
available space to copy the frame.
'Token' errors Increases when the active monitor detects a token protocol with any of the follow-
ing errors:
a) The token MONITOR_COUNT bit with nonzero priority equals one.
b) The frame MONITOR_COUNT bit equals one.
c) No token or frame is received within a 10ms window.
d) The starting delimiter/token sequence has a code violation in an area where
code violations cannot exist.
Too big frames Number of received frames with a bigger data field than the one supported by the
interface.
Mac Code Version Mac code version running in the Token Ring communications processor.

This section summarizes and then explains the Ethernet configuration commands. Enter these commands from the
ETH configuration menu.
Note
Not all commands specified in this section are available for all Ethernet interfaces. Depending on the
device, or on the interface configured, some commands may not appear.

11.00.07, 11.01.02 The "promiscuous-mode" command was introduced.
11.01.05 The "flow-control" command was introduced as of version 11.01.05.
3.3.2 AUTO-NEGOTIATION
Configures the Ethernet interface so that it operates in auto-negotiation mode. Here, the duplex mode is set and the
interface's speed is configured in accordance with the characteristics of the rest of the devices connected to the Eth-
ernet. The device with the worst characteristics limits the rest of devices connected to the Ethernet. If, for example,
several devices can operate at 100 Mbps and one can only operate at 10 Mbps, auto-negotiation configures the in-
terface to 10 Mbps.
Syntax:
ethernetX/X config>auto-negotiation
Example:
ethernet0/0 config>auto-negotiation
ethernet0/0 config>
Note
If devices connected with set speeds connect to an Ethernet interface where auto-negotiation is con-
figured, problems may arise. The auto-negotiation mode with set speeds will be unable to detect the
duplex mode of the other end. Thus, it will configure in half-duplex mode. Auto-negotiation is mandatory
for Gigabit connections. If the speed is set to 1000 Mbps, the device will internally switch to auto-
negotiation mode.
3.3.2.1 AUTO-NEGOTIATION ADVERTISE
Configures the characteristics advertised in auto-negotiation. To disable the advertising of characteristics, use the
auto-negotiation no advertise option. The following characteristics can be configured:
•flow-control: advertises all flow control options available (symmetric or both symmetric and asymmetric).
•flow-control asymmetric: advertises asymmetric flow control (does not advertise symmetric flow control).
•flow-control symmetric: advertises symmetric flow control (does not advertise asymmetric flow control).

3.3.3 CDP
Configures the CDP protocol in the interface.
3.3.4 DOT1Q
Configures the Ethertype field for the tags used when encapsulation is executed at the MAC level that corresponds
to the IEEE 802.1Q standard in Ethernet subinterfaces. For further information on the encapsulation of Ethernet
subinterfaces, please see manual Teldat Dm750-I Ethernet Subinterface. The default value for this field is 0x8100.
Syntax:
ethernetX/X config>dot1q tunneling ethertype <ethertype>
ethernetX/X config>dot1q tunneling ethertype ?
0x88A8 dot1q tunneling etype 0x88A8
0x9100 dot1q tunneling etype 0x9100
0x9200 dot1q tunneling etype 0x9200
Example:
ethernet0/0 config>dot1q tunneling ethertype 0x88A8
ethernet0/0 config>
Note
Encapsulation increases the Ethernet frame and can cause MTU/fragmentation problems in some
devices. To solve this, limit the subinterface IP MTU using the IP MTU command described in manual
Teldat Dm702-I TCP-IP Configuration .
3.3.5 DOT1X
Accesses the 802.1X authentication configuration. For further information on 802.1X authentication, please see
manual Teldat Dm783-I 802.1X Authentication.
Note
The dot1x command is not available when the Ethernet interface is internally connected to a switch.
Syntax:
ethernetX/X config>dot1x
Example:
ethernet0/0 config>dot1x
-- 802.1X User Config --
ethernet0/0 dot1X config>

3.3.6 DUPLEX
Configures the device duplex mode: half duplex or full duplex. If the device is configured with auto-negotiation, the
duplex mode configuration is ignored. The interface is configured in accordance with the characteristics of the
devices connected to the Ethernet.
Syntax:
ethernetX/X config>duplex <duplex mode>
Example 1:
ethernet0/0 config>duplex ?
full forces full duplex operation mode
half forces half duplex operation mode
ethernet0/0 config>
Example 2:
ethernet0/0 config>duplex full
ethernet0/0 config>
3.3.7 FLOW-CONTROL
Configures the flow control mode when the port is configured in fixed mode (i.e. with auto-negotiation disabled).
Syntax:
ethernetX/X config>flow-control
disabled Disable flow control
enabled Enable flow control
rx-only Enable asymmetric PAUSE toward local device
tx-only Enable asymmetric PAUSE toward link partner
Note
Flow control is not available in all switches.
Note
Asymmetric flow control is not available in all switches.

11.01.05 This command was introduced as of version 11.01.05.
3.3.8 INPUT-BUFFERS
Configures the number of buffers used at reception. The default value depends on the type of driver. We recommend
you not to modify this unless our technical personnel says otherwise.
Syntax:
ethernetX/X config>input-buffers <number of buffers>
Example:
ethernet0/0 config>input-buffers 50
ethernet0/0 config>
3.3.9 IP-ENCAPSULATION
Selects the IP transport mode in the Ethernet frame data field. Possible formats are: Ethernet (Ethernet type 8137) or
IEEE-802.3 (Ethernet 802.3 raw without 802.2). Default encapsulation is ETHERNET.

3.3.10 LIST
Displays the current configuration of the Ethernet interface. This includes the MAC address used by the interface, the
speed, the duplex mode and the IP encapsulation. Whenever the interface is configured using auto-negotiation, the
speed and the duplex mode are not displayed (as these are obtained from the characteristics of the devices connec-
ted to the Ethernet).
Syntax:
ethernetX/X config>list
Example 1:
ethernet0/0 config>list
MAC address: 000000000000
Speed: Auto-negotiation
IP encapsulation: ETHER

3.3.11 LLC
Accesses the LLC configuration. LLC configuration is mandatory to pass frames over the SNA network. See the LLC
Configuration Commands section for a description of the available commands and their use.
Syntax:
ethernetX/X config>llc
Example:
ethernet0/0 config>llc
-- LLC User Configuration --
ethernet0/0 LLC config>
3.3.12 LLDP
Configures the LLDP options in the interface. For further information on the Link Layer Discovery Protocol, please
see manual Teldat Dm813-I LLDP Protocol.
3.3.13 MAC-ADDRESS
The interface can adopt locally-administered addresses or those provided by the device manufacturer. Only locally-
administrated addresses are provided through this command. Entering 00-00-00-00-00-00 (default value) causes the
router to use the default factory station address. This last MAC address is used by default.
Syntax:
ethernetX/X config>mac-address <MAC address>
