The switch SWA and SWB are connected together by 2 Ethernet links, where the switch
SWA has the following interface configuration:

  1. Without changing the current configuration, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 can join the same aggregation group
  2. Because of the different VLANs allowed, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 cannot join the same aggregation group
  3. After link clustering is configured on both SWA and SWB, if MSTP is enabled on the switches SWA and SWB Both GigabitEthernetl1/0/1 and GigabitEthernetl/O/2 are the forwarding status of MSTP
  4. Only if the configuration of GigabitEthernet 1/0/2 is changed to match GigabitEthernet 1/0/1 can the two join the same aggregation group
