Q: Can S6700 10000M Port Connect to the 1000M Optical Module?

A: S6700 10000M port can connect to the 1000M optical module.

In V100R006C00SPC800, when the S6700 10000M port connects to a GE optical module, the port rate switches to 1000M and works in non-auto-negotiation mode. If the 10000M port connects to the 1000M optical port on the peer device, the 10000M port can become Up only when the peer device works in non-auto-negotiation mode. After the S6700 has V100R006SPH005 installed and the S6700 10000M port connects to a GE optical module, you can run the negotiation auto command to switch the port to auto-negotiation. In this case, the 10000M port can connect to the 1000M optical port in auto-negotiation mode.

In later versions of V100R006C00SPC800, when the S6700 10000M port connects to a GE optical module, the port rate switches to 1000M and works in auto-negotiation mode.

Q: After the shutdown and undo shutdown Commands Are Used on a Trunk Member Interface of an S6700, Traffic Is Interrupted. Why?

A: When the shutdown and undo shutdown commands are used on a trunk member interface of an S6700, the trunk bandwidth changes. The ifnet sends a port rate change event. MSTP responds to the event and delivers the Block flag to the outbound port. As a result, the outbound port cannot forward traffic. After 15s, MSTP delivers the forward flag to the port. Traffic can be forwarded. When the shutdown and undo shutdown commands are used on a trunk member interface of an S6700, traffic is interrupted for 15s.

Q: Can the S6700 Switches Be Configured Not to Take Any Action After Detecting Loops?

A: After loop detection is enabled on the S6700 switches:

• The switches perform the configured action after detecting a loop.

• The action can be changed but cannot be disabled. When the action is changed to trap, the switches only report a trap and do not take any action after detecting a loop.

Q: Do the S6700 Switches Transparently Transmit BPDUs by Default?

A: By default, the S6700 switches do not transparently transmit Bridge Protocol Data Unit (BPDUs).

Q: How Does a S6700 Switch Process a Packet Whose Source MAC Address Is the Same as the Bridge MAC Address?

A: A S6700 switch process such a packet according to whether a Layer 3 VLANIF interface corresponding to the VLAN ID of the packet has been created:

• If no VLANIF interface has been created, the switch forwards the packet at Layer 2.

• If such a VLANIF interface has been created, the switch discards the packet.

Q: Does the S6700 on Which vlan-mapping and vlan-stacking Are Configured Support remark 8021p?

A: The S6700 supports remark 8021p.

Q: Does the S6700 Support Blackhole Routes?

A: The S6700 V100R006 and later versions support blackhole routes. The following command configures a blackhole route: ip route-static ip-address mask NULL 0

Q: How to Configure Rate Limit on S6700?

A: When you configure rate limit, the following configuration is recommended:

• Set the CIR, CBS, and PBS values but not the PIR value.

• CBS = 200 x CIR

• PBS = 2 x CBS = 2 x 200 x CIR = 400 x CIR

The CIR value is expressed in kbit/s, and the CBS and PBS values are expressed in bytes.

• Set the rate limit for outgoing packets on the interface to 10 Mbit/s.

• [HUAWEI] interface ethernet 0/0/1

[HUAWEI-Ethernet0/0/1] qos lr outbound cir 10240 cbs 2048000

• Set the rate limit for incoming packets on the interface to 10 Mbit/s.

• [HUAWEI] interface ethernet 0/0/1

[HUAWEI-Ethernet0/0/1] qos lr inbound cir 10240 cbs 2048000
