N-Ring – Configuration
The Configuration tab under the N-Ring category will display the N-Ring basic configuration settings. By
default, N-Ring is in Auto Member mode and the N-Ring Aging Time is 20 seconds.
Following the Modify button on the above example, the administrator will see a list of configurable fields
for the N-Ring configuration, as below.
The N-Ring Aging Time has a default of 20 seconds and is separate from the Bridging Aging Time. N-Ring
Aging Time is used when the switch is an N-Ring Manager or becomes an active N-Ring Member, and in
either case N-Ring status includes for example:
“Switch is currently using N-Ring Aging Time = 20 Seconds”
Once these fields are filled in to meet the needs of the administrator’s network, the changes may be saved by
clicking the Update button at the bottom of the page.
NOTES:
1. N-Ring Manager cannot have RSTP or Trunking enabled.
2. RSTP & N-Ring are different modes and cannot share links or segments along those lines.
See the examples in the RSTP configuration section.
3. Do not use Trunking on an N-Ring manager. Do not connect the N-Ring to actively Trunking
ports on an Auto Member.
4. Do not create redundant links unless either RSTP or N-Ring is enabled.
5. Any one 708M12 or 716M12 can only participate in one N-Ring.
6. N-Ring copper ports must be run at 100Mb full duplex, including the default ‘autonegotiate’ as
long as all switches in the ring support 100Mb full duplex.
