Configuring HMP for Transparent Local Failover Support
Chapter 4 101
Thus, if a switch fails, HMP transparently fails over traffic only if at
least one member of the card pair is physically reachable through the
other switch.
Case 3: Cable Failure Between Two Switches (see Figure 4-9)
If a cable between two switches fails, HMP traffic fails over to the other
available cable between those two switches.
