Input/output port redundancy
You can protect I/O ports using a link aggregation mechanism. MultiLink Trunking (MLT), which
is compatible with 802.3ad static, provides a load sharing and failover mechanism to protect
against module, port, fiber, or complete link failures.
You can use MLT with Link Access Control Protocol (LACP) disabled or use LACP enabled
by itself.
Configuration redundancy
You can define primary and backup configuration file paths. This configuration protects against
system failures. For example, the primary path can point to system flash memory and the
backup path to the external Compact Flash card.
Link redundancy
Provide physical and link layer redundancy to eliminate a single point of failure in the network.

Link redundancy on page 35.
