  • ACT:1 (Active): Indicates that the LACP interface is currently active and operational.
  • TIM:1 (Timeout): Indicates that the timeout value for LACP packets is set to short, typically meaning fast failure detection.
  • AGG:1 (Aggregation): Indicates that aggregation is currently enabled for this interface.
  • SYN:1 (Synchronization): Indicates that synchronization is enabled, meaning that the device is synchronized with the remote end of the link aggregation.
  • COL:1 (Collecting): Indicates that the interface is currently in the collecting state, meaning it is able to both receive and transmit data.
  • DIS:1 (Distributing): Indicates that the interface is currently in the distributing state, meaning it is actively forwarding data.
  • DEF:0 (Defaulted): Indicates whether the interface has defaulted, which is not the case here (0 means no default).
  • EXP:0 (Expired): Indicates whether the interface has expired, which is not the case here (0 means not expired).
