Usage guidelines A device supports the global configuration mode. In system view, use the flow-interval command to set the statistics polling interval for all interfaces. Examples # Set the statistics polling interval to 100 seconds for all Ethernet interfaces. system-view [Sysname] flow-interval 100 interface Use interface to enter interface or subinterface view.

Default command level 2: System level Parameters external: Enables external loopback testing for all on-chip functions related to Ethernet interfaces. internal: Enables internal loopback testing for the hardware of Ethernet interfaces. Usage guidelines Enable loopback testing for troubleshooting purposes, such as identifying an Ethernet problem. You cannot perform internal or external loopback testing on an administratively down (ADM DOWN) port.
After you change the link mode of an Ethernet interface, all settings are restored to their default values in the new link mode. Examples # Configure GigabitEthernet 4/0/1 to operate in bridge mode. system-view [Sysname] interface gigabitethernet 4/0/1 [Sysname-GigabitEthernet4/0/1] display this # interface GigabitEthernet4/0/1 port link-mode route # Return The output shows that GigabitEthernet 4/0/1 operates in route mode.
Usage guidelines Depending on the hardware structure of interface cards, some interfaces can operate only as Layer 2 Ethernet interfaces (in bridge mode), some can operate only as Layer 3 Ethernet interfaces (in route mode), and others can operate as either Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to bridge or route). Configuring the port link-mode interface-list command in system view and configuring the port link-mode command in Ethernet interface view lead to the same result.

For more information about the port link-type command, see Layer 2—LAN Switching Command Reference.
Usage guidelines When a hybrid or trunk port detects a loop condition, it sends traps, whether loopback detection control is enabled or not. However, the port performs the protective action that you configure with the loopback-detection action command only after loopback detection control is enabled. This command is not applicable to access ports. Examples # Enable loopback detection control on the trunk port GigabitEthernet 4/0/1.
Table 12 Actions to take upon detection of a loop condition Port type Actions No protective action is configured • Place the interface in controlled mode. The Access port interface discards all incoming packets, but still forwards outgoing traffic. • Generate traps. • Delete all MAC address entries of the A protective action is configured • Perform the configured protective action. • Generate traps and log messages. • Delete all MAC address entries of the interface. interface. • Generate traps.

Usage guidelines In Ethernet interface view, the configurations take effect only on the interface.

Usage guidelines Multiple BERT test modes exist, as defined in ITU O.151, ITU O.153, and ANSI T1.403-1999. 2^11, 2^15, 2^20, 2^23, and QRSS are available on E1 channels created on CE3 interfaces. To perform a BERT test, the local end transmits test data stream, which is returned after reaching specific nodes. The local end then checks for the bit error rate by comparing the returned data stream with the original, through which the state of the link can be determined.
When an E1 line operates in framed (CE1) mode, you can bundle timeslots on it into channel sets. For each channel set, the system automatically creates a serial interface numbered serial number/line-number:set-number. For example, the serial interface formed by channel set 0 on the first E1 line on E3 1/0 is numbered 1/0/1:0. This interface can operate at N × 64 kbps, and is logically equivalent to a synchronous serial interface on which you can make other configurations.

Usage guidelines FEAC is a channel formed by using the third C-bit in the first subframe in C-bit framing. It is used to transmit alarm state signals for line test purposes, or to transmit loopback control code for activating or deactivating far-end loopback during a loopback test. According to ANSI T1.107a, the frame format used by FEAC channels is bit oriented protocol (BOP). At the startup of your router, FEAC channel signal detection is enabled on the CT3 interface with FEAC signal sending disabled.
Parameters c-bit: Sets the framing format to C-bit. m23: Sets the framing format to m23. Examples # Set the framing format of interface T3 2/0/0 to m23. system-view [Sysname] controller t3 2/0/0 [Sysname-T3 2/0/0] frame-format m23 ft3 Use ft3 to configure a CT3 interface to operate in the FT3 mode and set the DSU mode or the subrate. Use undo ft3 to restore the default.
Usage guidelines FT3 (Fractional T3 or Subrate T3) mode is a non-standard E3 application mode. In this mode, the subrate level setting varies with vendors. You can use the ft3 command to make the device to be compatible with devices of other vendors operating in specific FT3 DSU modes. This command is only applicable to CT3 boards that support FT3. This command is only available in CT3 mode. As for the ft3 subrate command, the actual subrate usually is not exactly the one set by the command.

Field Description Link status: • ADM—The interface has been administratively Link: ADM - administratively down; Stby - standby shut down. To recover its physical state, perform the undo shutdown command. • Stby—The interface is operating as a backup interface.

Syntax flag c2 flag-value undo flag c2 flag { j0 | j1 } { sdh | sonet } flag-value undo flag { j0 | j1 } { sdh | sonet } flag j1 ignore undo flag j1 ignore Default The default SDH overhead bytes are used.
sdh: Sets framing format to SDH. sonet: Sets framing format to SONET. Usage guidelines Inconsistency between the c2 and j1 settings of the sending POS interface and the receiving POS interface causes alarms. The J0 byte can be any character in the network of the same carrier. If two carriers are involved, make sure the sending and receiving devices use the same J0 byte at their network borders. Examples # Set the SDH overhead byte J0 of POS 2/1/0 interface.

Views POS interface view Default command level 2: System level Parameters fr: Specifies Frame Relay as the link layer protocol of the interface. ietf: Adopts the Interface Engineering Task Force (IETF) standard encapsulation format, which is the default encapsulation format.
Default command level 2: System level Parameters local: Enables internal loopback. remote: Enables external loopback. Usage guidelines Loopback is intended for test use. Disable it otherwise. If you enable loopback on a POS interface encapsulated with PPP, it is normal that the state of the link layer protocol is reported up. Loopback and clock slave cannot be set at the same time; otherwise, POS interfaces cannot be connected successfully. Examples # Enable internal loopback on interface POS 2/1/0.
HIM module model MTU value range HIM-RPR 128 to 9600 Usage guidelines The MTU setting of the POS interface can affect the assembly and fragmentation of IP packets. In QoS, the length of queues is limited. If MTU on the interface is too small, a large packet might be fragmented into so many fragments that the queue cannot hold them and discard them. To avoid this situation, extend the queue length by using the qos fifo queue-length command in interface view.
scramble Use scramble to enable payload scrambling on the POS interface. Use undo scramble to disable payload scrambling. Syntax scramble undo scramble Default Payload scrambling is enabled. Views POS interface view Default command level 2: System level Usage guidelines You can configure payload scrambling to prevent the presence of too many consecutive 1s or 0s, to facilitate line clock signal extraction at the receiving end. To connect POS interfaces, enable payload scrambling on both ends.
