Configure Stack Settings on the Active Switch
Active Switch Selection Process
The active unit is selected from the active-enabled units (1 or 2). The factors in selecting the active
unit are taken into account in the following priority:
System Up Time - The active-enabled units exchange up-time, which is measured in
segments of 10 minutes. The unit with the higher number of segments is selected. If both units
have the same number of time segments, and the unit ID of one of the units was set manually
while the unit ID of the other was set automatically, the unit with the manually-defined unit ID
is selected; otherwise the unit with the lowest unit ID is selected. If both units IDs are the
same, the unit with the lowest Media Access Control (MAC) address is chosen.
The up time of the Standby unit is retained when it is selected as active in the switch failover
process.
Unit ID - If both units have the same number of time segments, the unit with the lowest unit ID
is selected.
MAC Address - If both units IDs are the same, the unit with the lowest MAC address is
chosen.
For a stack to operate, it must have an active unit. An active unit is defined as the Active unit that
assumes the active role. The stack must contain a Unit 1 and/or Unit 2 after the active selection
process. Otherwise, the stack and all its units are partially shut down, not as a complete power-off,
but with traffic-passing capabilities halted.
Follow these steps to configure stack settings on the Active switch:
Step 1
Log in to the console of the first switch. The default username and password is cisco/cisco. If you
have configured a new username or password, enter the credentials instead.
