After all of the bundle parameters display, information about each individual link in the bundle displays.
Extra link-level parameters might be shown after each link in certain circumstances. The following list

Frag timeout n ms—The maximum amount of time that multilink waits for an expected fragment
before declaring it lost. This limit applies only when fragment loss cannot be detected by other,
faster means such as sequence number-based detection.
Member links:—The number of active and inactive links currently in the bundle, followed by the
desired minimum and maximum number of links. The actual number might be outside the range.
Weight—The weight is used for load balancing. Data is distributed between the member links in
proportion to their weight. The weight is proportional to multilink's notion of the effective
bandwidth of a link. Therefore, multilink effectively distributes data to the links in proportion to
their bandwidth.
The effective bandwidth of a link is the configured bandwidth value, except on asynchronous lines
where multilink uses a value that is 0.8 times the configured bandwidth setting. This exception
occurs because, on an asynchronous line, at best only 8/10 of the raw bandwidth is available for
transmitting real data and the remainder is consumed in framing overhead.
Previously, the weight also controlled the size of the fragments generated for that link. However,
Cisco IOS software now computes a separate fragment size value.
Frag size—The size of the largest fragment that can be generated for that link. It is the size of the
MLP payload carried by a fragment and does not include MLP headers or link-level framing.
Unsequenced—The serial link is unsequenced and packets can arrive in a different order than the
peer transmitted them. To compensate for this, multilink relaxes its lost fragment detection
mechanisms.
Receive only (or receive only pending)—The link is in idle mode or is about to be put in idle mode.
Processing of arriving data on the link continues normally, but data is not transmitted on the link.
The remote system is expected to not send data on the link.
