See show interfaces lag.
Use to display information about the Ethernet member links in all IEEE 802.3ad
link aggregation group (LAG) bundles configured on the router, or about the
member links in a specified IEEE 802.3ad LAG bundle.
Field descriptions
Lag Name of the LAG bundle
Administrative status Operational state that you configured for the LAG
Configured MinimumLinks Minimum number of member links are
configured for the LAG bundle
Member-interface Status of the member interface in the bundle
Interface Specifier Status of the hardware on this interface (up or down)
LACP active Ethernet link participates in the protocol regardless of
whether its Partner member link is set to active or passive LACP PDU
participation
LACP passive Ethernet link transmits LACP PDUs only when it receives
LACP PDUs from its Partner link
collecting/distributing Ethernet link is actively collecting incoming
frames and distributing outgoing frames
detached Ethernet link is detached from the LAG bundle due to protocol
changes or system constraints
waiting Ethernet link is waiting to attach to a LAG bundle
