How the MultiLink Trunk Reacts to Losing Distributed Trunk Members
If your MultiLink Trunk ( Figure 1-46 ) spans separate units in a stack
configuration and any of those units (or trunked MDAs) becomes inactive from a
loss of power or unit failure, the unaffected trunk members remain operational.
Figure 1-46. Loss of Distributed Trunk Members
However, until you correct the cause of the failure or change the trunk Status field
to Disabled, you will be unable to modify any of the following parameters for the
affected trunk:
• VLAN Configuration
• Spanning Tree Configuration
• Port Mirroring Configuration
• Port Configuration
• IGMP Configuration
• Rate Limiting Configuration
