    Q. How can I empty the recycle bin? A. Use the reset recycle-bin command. If a file in the recycle bin is corrupt, use the reset recycle-bin command with the /force option to delete the file. Q. Is software hotfix supported? A.
  • Page 10 • Flow control—None • Parity—None • Stop bits—1 • Data bits—8 • Terminal display type—VT100 If you are running the terminal software SecureCRT, you must deselect the DTR/DSR option and RTS/CTS option for flow control. By default, the RTS/CTS option is selected for flow control. Q.
  • Page 11 Q. Do all SR6600 service modules support IRF? A. Yes. Q. Can an H3C SR6600 router form an IRF fabric with any devices in the same series? A. No. When you set up an IRF fabric, follow these hardware restrictions and guidelines: •...
  • Page 12 A. An H3C SR6600 IRF fabric can have a maximum of two member chassis. Q. What topologies does an H3C SR6600 IRF fabric support? A. An H3C SR6600 IRF fabric only supports the daisy-chain topology. It does not support the ring topology.
  • Page 13 A. When you configure LACP MAD, make sure the intermediate device meets the following requirements: • The intermediate device is a Comware-based H3C device that can process the LACPDUs that convey the ActiveID field for MAD. • If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for correct split detection.
  • Page 14 Q. Why doesn't the running configuration on a reunified IRF fabric include the configuration that I made on one chassis after an IRF split? A. When an IRF fabric merges, the chassis in the Recovery-state IRF fabric reboots with the running configuration on the active IRF fabric.
  • Page 15 Q. Does the router support local authentication when the HWTACACS authentication fails? A. The router supports local authentication when the HWTACACS authentication fails because the server is not reachable. The router does not support local authentication when the HWTACACS authentication fails because of an incorrect username or password.
  • Page 16 Q. How do I prevent gateway spoofing when the router acts as a gateway? A.

Q. The RPF check fails after the MSDP peer switchover in inter-domain multicast routing. What are the possible reasons? A.
  • Page 21 Q. Why routing protocols are not recommended to be configured on the interface with Easy IP configured? A. With Easy IP configured, the interface puts all packets into one software queue to the CPU. If routing protocols are configured on the interface, a large number of protocol packets will be generated.
  • Page 22 Q. Does OpenFlow support VLAN interfaces? A. The VLAN interfaces support only MAC-IP flow tables and do not support extensibility flow tables.
