1.1.2 Configuring LAN/WAN Mode for a 10GE Interface

I. Introduction to LAN/WAN mode

According to the physical characteristics, a ten-GigabitEthernet (10GE) interface can

work in LAN or WAN mode.

z LAN mode. 10GE interfaces operating in this mode are used to provide network

access for Ethernets. They receive and forward Ethernet packets.

Operation Manual – Ethernet Interface

H3C S9500 Series Routing Switches Chapter 1 Ethernet Interface Configuration

1-2

z WAN mode. 10GE interfaces operating in this mode are used to provide network

access for SDH networks. They receive and forward synchronous digital hierarchy

(SDH) packets across point-to-point connections only.

 Note:

Although 10GE interfaces operating in WAN mode encapsulate Ethernet packets as

SDH frames, and 10G packets over SDH (POS) interfaces encapsulate PPP packets

as SDH frames, the two types of SDH frames differ in frame format. Therefore, a 10GE

interface operating in WAN mode cannot communicate a 10G POS interface.

II. Introduction to J0/J1 overhead byte

SDH frames have diversified overhead bytes, which accomplish the operation and

maintenance functions such as hierarchical management of the transport network. J0

and J1 are used to provide internetworking support between different countries, regions,

or devices of different manufacturers.

The regenerator section trace byte J0 is usually set to a section access point identifier.

The sending end keeps connected with the receiving end by sending this byte

repeatedly.

The path trace byte J1, usually set to a high-order path access point identifier, functions

in a similar to keep the connection with the receiving end of the path.

To ensure smooth communication, the J0 and J1 bytes should be matched respectively

at the sending and receiving ends. For details about SDH and SDH overhead bytes,

refer to related documents.

III. Configure a 10GE interface to operate in LAN/WAN mode

flag-value

Optional

By default, the value of

the J0/J1 bytes is 0.

 Note:

z The flag command is available only when the 10GE interface is operating in WAN

mode.

z WAN mode is not supported on LSB1XP4CA, LSB1XK1DB, and LSB1XP4B

boards.

1.1.3 Basic Ethernet Interface Configuration

Three types of duplex modes are available for Ethernet interfaces:

z Full-duplex mode (full). Interfaces operating in this mode can send and receive

packets simultaneously.

z Half-duplex mode (half). Interfaces operating in this mode can either send or

receive packets at a given time.

z Auto-negotiation mode (auto). Interfaces operating in this mode determine their

duplex mode through auto-negotiation.

If you configure the transmission rate for an Ethernet interface with the speed auto

command, the transmission rate is determined through auto-negotiation.

Follow these steps to perform basic Ethernet interface configurations:

interface

Shutdown

Optional

By default, an Ethernet

interface is in up state.

Use the undo shutdown

command to bring up the

interface.

 Note:

z The speed 1000 command is only available for GigabitEthernet interfaces.

z GigabitEthernet electric interfaces cannot operate in half-duplex mode when the

transmission rate is set to 1000 Mbps.

z Ethernet optical interfaces cannot operate in half-duplex mode.

z You cannot set the transmission rate of a ten-GigabitEthernet or 100-Mbps Ethernet

optical interface. For a 1000-Mbps Ethernet optical interface, you can only set the

transmission rate to 1000 Mbps or auto negotiation.

z When an O/E converter is used for an interface, set the duplex mode of the interface

to auto for the interface to operate normally.

1.1.4 Configuring Flow Control on an Ethernet Interface

When flow control is enabled on both sides, if traffic congestion occurs at the ingress

interface, it will send a Pause frame notifying the egress interface to temporarily

suspend the sending of packets. The egress interface is expected to stop sending any

new packets when it receives the Pause frame. In this way, flow controls helps to avoid

the dropping of packets. Note that only after both the ingress and the egress interfaces

have turned on their flow control will this be possible.

Follow these steps to enable flow control on an Ethernet interface:

1.1.5 Configuring Physical State Change Suppression on an Ethernet

Interface

An Ethernet interface operates in one of the two physical link states: up or down. During

the suppression time, physical-link-state changes will not be propagated to the system.

Only after the suppression time has elapsed will the system be notified of the

physical-link-state changes by the physical layer. This functionality reduces the extra

overhead occurred due to frequent physical-link-state changes within a short period of

time.

Follow these steps to configure the up/down suppression time on an Ethernet Interface:

Required

Defaults to 1 second.

1.1.6 Configuring Loopback Testing on an Ethernet Interface

You can enable loopback testing to check whether the Ethernet interface functions

properly. Note that no data packets can be forwarded during the testing. Loopback

testing falls into the following two categories:

z Internal loopback testing: a loopback testing carried out within the device, if data

packets sent from an Ethernet interface can be received by the same interface, the

internal loopback testing is successful indicating that the interface is functioning

properly.

z External loopback testing: a loopback plug needs to be plugged into an Ethernet

interface, if data packets sent from the interface is received by the same interface

through the loopback plug, the external loopback testing is successful indicating

that the interface is functioning properly.

Follow these steps to enable Ethernet interface loopback testing:

loopback { external |

internal }

Optional

Disabled by default.

 Note:

z Currently, the S9500 series routing switches do not support the external loopback

testing.

z Internal loopback testing can only be enabled on interfaces in down state. That is, it

is unavailable to interfaces that are shut down manually.

z The speed, duplex, mdi, and shutdown commands are not applicable during a

loopback testing.

z With the loopback testing enabled, the Ethernet interface works in the full duplex

mode at highest speed. With the loopback testing enabled, the original

configurations will be restored.

1.1.7 Configuring a Manual Port Group

To make the configuration task easier for users, certain devices allow users to configure

on a single port as well as on multiple ports in a port group. In manual port group view,

the user only needs to input the configuration command once and that configuration will

apply to all ports in the port group. This effectively reduces redundant configurations.

Configuration in the Access Volume.

1.1.8 Configuring Traffic Suppression for an Ethernet Interface

You can suppress the broadcast and multicast traffic passing through an Ethernet

interface.

When the traffic over the interface exceeds the pre-set threshold, the system will

discard the extra packets to ensure that the network functions properly.

Operation Manual – Ethernet Interface

H3C S9500 Series Routing Switches Chapter 1 Ethernet Interface Configuration

1-8

 Note:

z You cannot enable broadcast suppression and multicast suppression on a board at

the same time. If you have enabled broadcast suppression on some ports of a board,

you cannot enable multicast suppression on the other ports, and vice versa.

z Before enabling multicast suppression on a port, you must disable broadcast

suppression on all the other ports on the same board. Similarly, before enabling

broadcast suppression on a port, you must disable multicast suppression on all the

other ports on the same board.

z The multicast suppression function suppresses broadcast traffic in addition to

multicast traffic but the broadcast suppression does not suppress multicast traffic.

1.1.9 Setting the Interval for Collecting Ethernet Interface Statistics

Complete the following configuration tasks to configure the time interval for collecting

interface statistics. Use the display interface command to display the interface

statistics within the current interval.

1.1.10 Setting the Maximum Jumbo Frame Size for Ethernet Interfaces

Usually, an Ethernet interface discards received jumbo frames (frames larger than the

standard Ethernet frame size) directly without processing them. To handle jumbo

frames under a certain size, which may be received during large-throughput data

switching like file transfer, you can set a jumbo Ethernet frame size limit on the switch.

Follow these steps to set the maximum jumbo frame size for the Ethernet interfaces on

a board:

Operation Manual – Ethernet Interface

Set the maximum size of the

jumbo frames allowed to pass

through an Ethernet interface

on a board

jumboframe enable

[ jumboframe-value ] slot

Optional

1552 bytes by

default.

 Note:

z The allowed maximum frame size is 10236 bytes on non-line-speed XP4 boards

and LSB1GV48 boards and 10240 bytes on other GE and 10GE boards.

z You can configure the jumbo frame size in the range 1552 to 10240 in bytes.

However, if the size is set in the range 1553 to 9022, the value 9022 takes effect; if

the size is set in the range 9023 to 9192, the value 9192 takes effect; if the size is set

in the range 9193 to 10240, 10240 takes effect.

1.1.11 Configuring the MDI Mode of an Ethernet Interface

You can connect an Ethernet interface with a crossover or straight-through cable,

depending on its medium dependent interface (MDI) mode. The MDI mode can be one

of the following:

z Across mode, where the Ethernet interface can be connected only to a crossover

cable.

z Normal mode, where the Ethernet interface can be connected only to a

straight-through cable.

z Auto mode, where the Ethernet interface can be connected to either a

straight-through cable or a crossover cable.

Use the auto mode in normal cases. In case the interface in auto mode cannot

recognize the type of the connected cable, set its MDI mode to across or normal.

Follow these steps to configure the MDI mode of an Ethernet Interface:

role of the pins (to send

packets or receive

packets) through auto

negotiation.

Caution:

You can configure the cable type of 10/100 Mbps and 10/100/1000 Mbps electrical

interfaces only. The cable type of optical Ethernet interfaces is not configurable.

1.1.12 Configuring the Source MAC Address for an Interface

Normally, when a packet is forwarded by an S9500 switch on Layer 3, its source MAC

address is that of the VLAN interface which the outbound interface corresponds to.

However, It is required in some cases that the source MAC addresses of packets

forwarded through different interfaces be different for forwarding policies to take effect

on the peer devices.

By configuring the source MAC address for an interface, you can set the least octet of

the source MAC addresses of the packets forwarded through the interface for

forwarding policies to take effect on the peer devices.

Follow these steps to configure the source MAC address for an interface:

To do... Use the command... Remarks

Enter system view

system-view

—

Enter Ethernet interface

Required

By default, the source

MAC address of an

interface is that of the

corresponding VLAN

interface.

Operation Manual – Ethernet Interface

H3C S9500 Series Routing Switches Chapter 1 Ethernet Interface Configuration

1-11

Caution:

After you configure the source MAC address for an interface, packets forwarded on

Layer 3 through the interface use the MAC address of the corresponding VLAN

interface as their source MAC addresses, with the least octet being replaced with value

specified by the source-mac-tail command.

 Note:

Currently, this command is not supported on the following boards: LSB1GV48DA,

LSB1GV48DB, LSB2GV48DA, LSB1GP48DB, LSB1XP4B, LSB1XP4CA, and

LSB1XP4DB.
