Local Services
Local services provided by LNM Servers enable you to control each station
attached to a token ring segment.
Some examples of local services provided by LNM Servers are
• Initializing new stations with the same parameters used to initialize all other
stations attached to the same ring
• Noting the address of the Next Active Upstream Neighbor for each station on
a ring
• Collecting error detection messages placed on a specified ring by stations
already attached to the same ring
Network-Wide Services
Network-wide services provided by LNM Servers enable you to configure and
monitor, from a central site, the operation of each segment of a token ring LAN.
Some examples of network-wide services are
• Requesting statistics or configuration information from LNM Servers
• Removing a ring station from a designated ring
• Collecting error information about the operation of a designated ring
• Permitting manual intervention where necessary to resolve certain operational
problems existing on a designated ring
