Switch Management Commands 2255
configured in a stack and can utilize rear panel mini-SAS ports only for
stacking. The N1500 Series switches support stacking up to four units in a
stack and can utilize pairs of SFP+ ports for stacking.
On the N1500 Series switch, configuring an SFP+ port as stacking will always
configure the corresponding pair in stacking mode as well (i.e., configuring
Te1/0/1 as stacking configures Te1/0/2 as stacking and configuring Te1/0/3 as
stacking configures Te1/0/4 as stacking).
Example
console(config-stack)#stack-port tengigabitethernet 1/0/3 stack
console(config-stack)#
stack-port shutdown
Use this command to enable or disable the stack port administratively. This
command is usually used to diagnose the stack in case any one of the stack
ports is exhibiting errors.
Syntax
stack-port interface-id shutdown
no stack-port
interface-id shutdown
• interface-id —The stacking interface identifier.
Default Configuration
There no default configuration for this command.
Command Modes
Stack Configuration mode
User Guidelines
This command must be used with caution, as disabling a stack port causes
the stack to attempt to reconverge. Ensure that the stack is in an active ring
topology in order to avoid a stack split. Check the stack ports for errors and
also verify that NSF is synced before shutting down any stacking links.
Application messages will appear in the logs during stack convergence.
