Error Message and Recovery Procedures
Error Message GIGASTACK-6-LOOP_DETECTED
Explanation
master loop breaker. Link 2 of this GigaStack GBIC is disabled to break the loop.
Recommended Action
Error Message GIGASTACK-6-NO_LOOP_DETECT
Explanation
links on a GigaStack GBIC. Either the neighboring switch does not support the GigaStack
loop-breaking algorithm, or the link between the two GigaStack GBICs is broken. Under this
condition, a GigaStack loop topology is not automatically detected, and the connectivity between
switches in the stack could be lost.
Recommended Action
running on all switches in the stack. Verify that the GigaStack GBICs involved are functioning.
Error Message GIGASTACK-6-LOOP_BROKEN: Link loss is detected in the Gigastack
loop\nLink 2 of the Gigastack GBIC in [chars] is re-enabled.
Explanation
loop breaker is re-enabled to replace the broken link
Recommended Action
Error Message GIGASTACK-6-LOOP_DETECTED: Gigastack GBIC in [chars] is selected as
Master Loop Breaker. \nLink 2 of the Gigastack GBIC is disabled to break the loop.
Explanation
