Huawei S9700 8-Port 40GBASE-X Interface Card (FC, QSFP+) EH1D2L08QFC0

Application

A 40GE network can be established by installing 40GE cards on aggregation switches and core switches (S9700), as shown in Figure 1.

Figure 1 40GE cards deployed on a campus network 

Huawei S9700 supports 40 GE cards EH1D2L02QFC0 and EH1D2L08QFC0. A 40GE network with 40GE cards deployed has the following advantages:

• Provides higher bandwidth.
• Is compatible with 10GE networks because a 40GE interface can be split into four 10GE interfaces. This feature enables customers to seamlessly upgrade their 10GE networks to 40GE networks.
• Has a higher efficiency and lower packet loss ratio than a 40GE network established by bundling four 10GE lines for load balancing.

The 40GE cards are used on networks that need to provide high bandwidth, for example, video surveillance bearer networks and high-definition (HD) video conference bearer networks. The following uses an HD video conference bearer network as an example to describe application of 40GE cards.

Transmission of HD video and voice flows consumes high bandwidth on a network, especially on the aggregation layer and core layer. Aggregation and core devices usually become bottlenecks on an HD video conference bearer network. As shown in Figure 1, 40GE cards are deployed on the aggregation layer and core layer to transmit HD video and voice flows faster, more efficiently, with fewer packets lost. This deployment ensures sufficient bandwidth for the HD video conference bearer network and delivers high quality HD images and voice.

Huawei N2SLQ16 Board Interconnected with the TQS Board Reports an R_LOS Alarm

Symptom

When Huawei N2SLQ16 board on an Huawei OptiX OSN 7500 NE is interconnected with the TQS board on an OptiX OSN 6800 NE at an office and no service is deployed on the TQS board, the N2SLQ16 board reports an R_LOS alarm when the optical power is normal. After a software outloop is performed on the TQS board, the alarm reported on the N2SLQ16 board is changed to R_LOF.

Cause Analyze

No service is deployed on the TQS board. Therefore, an R_LOF not an R_LOS alarm should be reported when the TQS board is interconnected with the N2SLQ16 board and when the optical power is normal. Since the N2SLQ16 is not faulty, the possible cause of the R_LOS alarm is that signals are lost rather than that the optical power is abnormal. That is, the N2SLQ16 board may receive white lights.

Under the condition that signals are scrambled but not framed on the TQS board, the initial values of the output signals on the WDM side of the TQS board are all zero. At this time, the optical module on the TQS board outputs white lights. When a loopback is performed on the TQS board, that is, signals on the optical module are framed and scrambled for initialization, the TQS no longer outputs white lights but random signal lights. As a result, the downstream N2SLQ16 board does not report the R_LOS alarm.

Procedure

1.         Query the alarm mode of the OptiX OSN 6800 NE on the T2000. The result shows that the alarm mode is set to automatic reversion for the NE but the automatic reversion function is not enabled at the optical interface.

2.         Replace the N2SLQ16 board or the optical module on the board but the problem persists. Perform a hardware loopback at the optical interfaces on the N2SLQ16 board by using an optical fiber. The R_LOS alarm disappears. The possibility that the N2SLQ16 board or the optical module on the board is faulty is excluded.

3.         Analyze that the TQS board interconnected with the N2SLQ16 board may be faulty. That is, the lights transmitted by the TQS board may be white, and therefore signals on the N2SLQ16 board are lost. On the T2000, set the client-side optical interfaces on the TQS board to Outloop. At this time, the alarm on the N2SLQ16 board is changed from R_LOS to R_LOF. The fault is rectified.

Huawei OTN Equipment Fails to Transparently Transmit Ethernet Clock Signals

Symptom Clocks between PTN equipment must be synchronized. Network AM using the OTN network architecture is configured between PTN equipment to transparently transmit clock signals from upstream PTN equipment to downstream PTN equipment or to implement network-wide clock synchronization. After the network is set up according to the network topology, the clock synchronization fails. The following figure shows the network topology. Figure 1 The Network Topology of AM Network  Cause Analysis The OptiX OSN 6800/OptiX OSN 8800 earlier than V100R006C01 cannot directly restore clock signals from 10GE services transmitted from PTN equipment. Therefore, clock signals are transparently transmitted from the upstream PTN equipment to the downstream PTN equipment. According to the network topology, PTN equipment transmits 10GE LAN services to the OTN network that consists of NG WDM equipment. The TN52TQX board is configured on the OptiX OSN 6800/OptiX OSN 8800 equipment and is set to the MAC Transparent Mapping (10.7G) mode. This network topology, however, cannot implement clock transparent transmission because of the MAC Transparent Mapping (10.7G) mode and Bit Transparent Mapping (11.1G) mode when clock signals are processed. 10GE LAN services can be set to 10GE LAN MAC Transparent Mapping (10.7G) mode or 10GE LAN Bit Transparent Mapping (11.1G) mode. The differences are as follows: ·         In the 10GE LAN MAC Transparent Mapping (10.7G) mode: 10GE LAN signals are encapsulated in the GFP-F mode and then mapped into standard OTU2 frames. In this mode, 10GE MAC frames are transparently transmitted. In addition, the equipment working in this mode supports standard OTU2 frames at the rate of 10.71 Gbit/s and can be interconnected with all equipment that supports standard protocol rates. In this mode, the local clock is traced and service clock signals cannot be transparently transmitted. ·         In the 10GE LAN Bit Transparent Mapping (11.1G) mode: Client 10GE LAN signals are directly mapped into OTU2 frames and transmitted at the rate of 11.1 Gbit/s. The transmission is implemented by extending the OTU2 frame structure and the transmission rate is higher than standard OTU2 signals. In this mode, the service clock is traced, and service clock signals can be transparently transmitted after the line rate is set to speed-up mode for the TN52TQX board. ·         To transmit link information in client services, you must set the MAC Transparent Mapping (10.7G) mode and enable the LPT function or set the Bit Transparent Mapping (11.1G)mode for the TN52TQX board. Procedure 1.    Set the Working Mode to Bit Transparent Mapping (11.1G) mode and the line rate to Speed-up Mode for the service board. Result The problem is resolved. Reference Information The NG WDM equipment traces the local clock or service clock based on the service type. Generally, the service clock is traced, and clock transparent transmission is supported when OTN boards are configured with the maximum supported cross-connect granularity and are set to the Speed-up Mode. Clock synchronization can be achieved by means of transparent transmission and network-wide clock synchronization. The OptiX OSN 6800/OptiX OSN 8800 earlier than V100R006C01 can only transparently transmit 10GE services and clocks between PTN equipment. The same is true for SDH services (transparent transmission is implemented using SDH boards). Network-wide clock synchronization can be achieved only when the TN52TOG board is interconnected to PTN equipment to transmit GE services. On the OTN network, the boards that support the IEEE 1588 feature can transmit physical clocks.

How to Implement the Binding of the IP Address and Interface?

Huawei Switch implements binding between an interface and an IP address through the traffic
policy and DHCP snooping. Then the interface allows only the packets with the bound IP
address and packets matching the DHCP snooping binding table to pass through. The Switch like Huawei 48-ports 10GE SFP+ switch S6720-54C-EI-48S-DC does support binding of IP address + MAC address + interface.
For example, to configure GigabitEthernet 0/0/8 to allow packets with the source IP address
being 192.168.130.50 apart from of the packets matching the DHCP snooping binding table,
and discard other packets, do as follows:
# Enable DHCP snooping globally.
[HUAWEI] dhcp snooping enable
# Configure an advanced ACL that matches source IP address 192.168.130.50.
[HUAWEI] acl 3000
[HUAWEI-acl-adv-3000] rule 5 permit ip source 192.168.130.50 0
[HUAWEI-acl-adv-3000] rule 10 deny ip source any
[HUAWEI-acl-adv-3000] rule 15 deny ip destination any
[HUAWEI-acl-adv-3000] quit
# Create a traffic classifier that matches the advanced ACL.
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 3000
[HUAWEI-classifier-c1] quit
# Create a traffic behavior and a traffic policy.
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] permit
[HUAWEI-behavior-b1] quit
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1
[HUAWEI-trafficpolicy-p1] quit
# Apply the traffic policy to GigabitEthernet 0/0/8 so that the interface allows only the
packets with the source IP address 192.168.130.50 to pass through apart from of the packets
matching the DHCP snooping binding table.
In V100R005 and later versions, the configuration is as follows:
[HUAWEI] interface GigabitEthernet 0/0/8
[HUAWEI-GigabitEthernet0/0/8] port default vlan 4094
[HUAWEI-GigabitEthernet0/0/8] ip source check user-bind enable
[HUAWEI-GigabitEthernet0/0/8] traffic-policy p1 inbound
