PowerConnect B-Series FCX hitless stacking
5
Enabling hitless stacking
Hitless stacking is disabled by default. To enable it, enable hitless failover as described in
“Enabling hitless failover” on page 175.
Displaying hitless stacking status
You can use the show stack command to view whether or not hitless stacking is enabled. The
following example shows that hitless stacking is disabled.
Syntax: show stack
Displaying pending device roles
When hitless stacking is disabled, a priority change will trigger an election, but the newly-elected
winner will not assume its role until the entire stack is reloaded or hitless stacking is enabled.
You can use the show stack command to view pending device roles. The “Role” column displays the
current role for each unit. The “Comment” column displays the role that will take effect after a
reload or when hitless stacking is enabled.
