Stack Member Priority Values - Cisco Catalyst 3560CX Series Manual

Managing Switch Stacks
As described in the hardware installation guide, you can use the device port LEDs in Stack mode to visually
determine the stack member number of each stack member.
In the default mode Stack LED will blink in green color only on the active switch. However, when we scroll
the Mode button to Stack option - Stack LED will glow green on all the stack members.
When mode button is scrolled to Stack option, the switch number of each stack member will be displayed as
LEDs on the first five ports of that switch. The switch number is displayed in binary format for all stack
members. On the switch, the amber LED indicates value 0 and green LED indicates value 1.
Example for switch number 5 (Binary - 00101):
First five LEDs glow as follows on stack member with switch number 5.
• Port-1 : Amber
• Port-2 : Amber
• Port-3 : Green
• Port-4 : Amber
• Port-5 : Green
Similarly, the first five LEDs glow amber or green, depending on the switch number on all stack members.
Note
• If you connect a Horizontal stack port to a normal network port on other end, stack port
• Stack port will not go down but only transmission/reception will be disabled. The log message shown

Stack Member Priority Values

A higher priority value for a stack member increases the probability of it being elected active switch and
retaining its stack member number. The priority value can be 1 to 15. The default priority value is 1. You can
display the stack member priority value by using the show switch EXEC command.
Note We recommend assigning the highest priority value to the device that you prefer to be the active device. This
ensures that the device is reelected as the active device if a reelection occurs.
To change the priority value for a stack member, use the switch stack-member-number priority new
priority-value command. For more information, see the "Setting the Stack Member Priority Value" section.
transmission/reception will be disabled within 30 seconds if no SDP packets are received from the other
end.
below will be displayed on the console. Once the peer end network port is converted to stack port,
transmission/reception on this stack port will be enabled.
