MAGNUM 6K SWITCHES, MNS-6K USER GUIDE
Rings are simple structures. Either one port of a pair is forwarding or both are. Not
complicated; not much to go wrong.
Configuring RS-Ring
RS-Ring is a licensed software feature from GarrettCom Inc. Before using the RS-Ring
capabilities; authorize the use of the software with the S-Ring license key. The same license
key is used for either the S-Ring or RS-Ring. To obtain the license key, please contact
GarrettCom Inc. Sales (for purchasing the S-Ring feature) or Technical Support (to obtain
the 12 character key.) If the S-Ring capability was purchased along with the switch, the
software license code will be included with the switch.
Syntax authorize <module> key=<security key> - activate the RS-Ring (or S-Ring) capabilities.
Don’t forget to use the “save” command to save the key
Magnum6K25# authorize s-ring key=abc123456789

FIGURE 91 – Activating RS-Ring on the switch
Since RS-Ring uses RSTP, RSTP has to be activated and enabled. Please refer to the Chapter
on Rapid Spanning Tree Protocol (RSTP) for more information. Some of the commands are
repeated here for clarity. Using RS-Ring with multiple switches, it is recommended to do the
following:
1) On all switches in the ring topology, authorize the use of RS-Ring software
2) On all the switches in the ring, enable RSTP
3) On all the switches in the ring designate the ports which make the ring pair
4) Only the ports on the RS-Ring must be enabled with RS-Ring capability
5) DO NOT enable S-Ring and RS-Ring in a given ring at the same time.
6) Enable RS-Ring on each switch
Ports associated with RS-Ring should have the following settings
• Same Speed - 100Mbps connection provides faster recovery than 10 Mbps
networks
• Same Duplex capabilities -
The necessary commands are
