2Valid port numbers depend on the model of SmartSwitch 1800—see port locations on
page 6- 1. Make sure the port is n ot configured (in the Port record) for bac kup us e onl y.
3Make sure the DLCI is not part of a frame relay D LCI backup group. Also make sure th e
DLCI is not the one configured on the port as a frame relay PVC.
4If Native LLC2, the interface can be used only for terminated LLC2 traffic.
5Configured in LLC2 Host file.
6Must be unique among all LAN IDs throughout the network on which this node will
operate.
Interf ace Ty pe
identifies whether the interface is on a LAN or a frame relay network.
Blocked Po rt Flag
causes the port to be enabled (N) or disa ble d (Y) at node IPL. The interface will remain
in that state until this parameter is changed and an on-line update of the bridge port is
perfor med.
Port Pr ior ity
will become the first octet of the Por t ID fiel d in Sp anning Tree P rotoc ol mes sages . The
lower the number, the higher the priority that the interface will be given among other
interfaces in the spanning tree.
Path Co st
is the "cost" of transmitting a frame through the port onto the LAN. This cost, deter-
mined by the speed of the LAN/port (the higher th e speed, the lowe r the cost), will be
added together with all other path costs on a specific link between source and desti-
nation devices. The total will then be compared to other total path costs to determine
the least "expensive" end-to-end path.
Prior ity
prioritizes this interface for intra-nodal traffic; the higher the number, the higher the
priority. (This priority has no effect on traffic exiting a node.)
Priorities are configured on all logical interfaces that use a physical frame relay port.
The device processor in the node uses these priorities to help determine the order in
which it will process protocols.
This pr iorit y h as no co nnect ion to Brid ge Prior ity or Port Pr iority.
When configuring priorities, be careful to consider the types of
traffic being routed on other connections in the node.
Port identifies the physical port containing the interface.
Make sure the physical frame relay port is not reserved for
backup DLCIs (as determined by the For Backup Use Only?
parame ter in the p ort record ).
DLCI matches the connection with an interface at the remote end of the link.
