Link OK This shows if the link is stable.
The link partner is a stack port on a neighbor
switch.
• No—The link partner receives invalid
protocol messages from the port.
• Yes—The link partner receives valid protocol
messages from the port.
Link Active This shows if the stack port is in the same state as
its link partner.
• No—The port cannot send traffic to the link
partner.
• Yes—The port can send traffic to the link
partner.
Sync OK
• No—The link partner does not send valid
protocol messages to the stack port.
• Yes—The link partner sends valid protocol
messages to the port.
# Changes to LinkOK This shows the relative stability of the link.
If a large number of changes occur in a short
period of time, link flapping can occur.
In Loopback
• No— At least one stack port on the member
has an attached stack cable.
• Yes—None of the stack ports on the member
has an attached stack cable.
