Q&A

Questions & Answers

How to Configure Rate Limit on S6720-54C-EI-48S-AC?

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.

How Do I Choose Single-mode and Multi-mode Optical Modules?

Multi-mode optical modules are applicable to short-distance transmission, while single-mode optical modules are applicable to long-distance transmission. Single-mode optical modules will be widely used in future.

Does the Switch Support PoE?

No, it doesn't. If the model name of a switch contains PWR or PWH, this switch supports the PoE function.

Does the S6720-54C-EI-48S-AC Support the Optical Modules of Other Vendors?

The 6700 switches can use only the certificated optical modules. If an uncertificated optical module is used, an error may occur and Huawei is not responsible for it.

Does the S6720-54C-EI-48S-AC on Which vlan-mapping and vlan-stacking Are Configured Support remark 8021p?

The S6700 supports remark 8021p.

Does this S6720-54C-EI-48S-AC support stack function?

Yes.

Can theS6720-54C-EI-48S-AC Use AC and DC Power Supply Simultaneously?

In V100R006C01 and later versions, the S6700 cannot use AC and DC power supply simultaneously. In versions prior to V200R005C00, the S6700-EI cannot use AC and DC power supply simultaneously. In V200R005C00, the S6700-EI can use AC and DC power supply simultaneously.

How Do I Check Default Configurations on an Interface?

In V200R001C00 and later versions, run the display this include-default command in the interface view. All configurations including default configurations on the interface are displayed.

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

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.

What is the Typical Power Consumption of S6720-54C-EI-48S-AC?

AC: without subcard: 190W with subcard: 209W
