Table 76 displays the individual devices and the Multi-Chassis Trunking (MCT) features they
support.
About Multi-Chassis Trunk (MCT)
A Multi-Chassis Trunk (MCT) is a trunk that initiates at a single MCT-unaware server or switch and
terminates at two MCT-aware switches.
Link Aggregation (LAG) trunks provide link level redundancy and increased capacity. However, LAG
trunks do not provide switch-level redundancy. If the switch to which the LAG trunk is attached fails,
the entire LAG trunk loses network connectivity. With MCT, member links of the LAG are connected
to two chassis. The MCT switches may be directly connected using an Inter-Chassis Link (ICL) to
enable data flow and control messages between them. In this model, if one MCT switch fails, a data
path will remain through the other switch.
