Eth can be avoided by-Trunk interface frequently flaps interface due to physical link eth-trunk 1 lacp preempt enable lacp preempt delay delay-time
You can configure the source IP address for load balancing in an enabled link aggregation group through the following commands: interface eth-trunk 1
load-balance src-dst-ip
Member interfaces can be removed from an enabled link aggregation group with the following command: interface GigabitEthermet0/0/1 shutdownwn

  1. interface GigabitEthernet0/0/1 undo eth-trunk 1
  2. interface GigabitEthernet0/0/1 undo shutdownwn
  3. Member interfaces can be added to a link aggregation group enabled by the following command:
    interface GigabitEthermet0/0/1 shutdownwn
  4. interface GigabitEthernet0/0/1 trunkport GigabitEthernet0/0/1 interface GigabitEthermet0/0/1 undo shutdownwn

Answer(s): A,C,D

Explanation:

Aggregation group join interface interface GigabitEthermet0/0/1 shutdown eth-trunk 1 undo shutdownwn



In the laboratory network, build a network according to the following topology diagram, SW1 is the default configuration, and SW2 disables the switch STP function.
Which is the correct description in this scenario? (single choice)

  1. G0/0/2 of SW1 entersDiscarding state
  2. G0/0/1 of SW2 entersDiscarding state
  3. G0/0/2 of SW2 entersDiscarding state
  4. No interface is blocked
  5. G0/0/1 of SW1 entersDiscarding state

Answer(s): D

Explanation:

STP not established



When DLDP detects the existence of a unidirectional link in the fiber, the default actions of Huawei equipment include:The DLDP state machine transitions to the Disable state; outputs Trap information; automatically sets the interface to the blocked state. ( confirmed)

  1. True
  2. false

Answer(s): A

Explanation:

If a unidirectional link is found, the DLDP protocol will automatically shut down or notify the user to manually shut down the relevant interface according to user configuration to prevent network problems from occurring.



Which of the following are used in Ethernet? (Multiple Choice)

  1. MAC address in non-canonical format
  2. in multiple accessCSMA/CD
  3. Canonical format of the MAC address
  4. 802.5 encapsulated frame
  5. 802.3 encapsulated frames

Answer(s): B,C,E

Explanation:

IEEEE 802.3 defines medium access control (MA) for the physical layer and data link layer of wired Ethernet.C) IEEE 802.5 Usually order card ring network
