6-8 Station List

Station List
The Station List illustrates the configuration of the HSIM-F6 managed ring,
including number of nodes on the ring, node addresses (both Canonical and
MAC), node class, and ring topology.
The Station List provides the following information about the HSIM-F6 controlled
ring:
Number of Nodes
The number of stations inserted into the FDDI ring to which the HSIM-F6 MAC is
connected.
TIP
You can use any SNMP Set Request or MIB tool to edit the Connection Policy for your
device by setting the fddimibSMTConnectionPolicy MIB OID (part of the MIBII
FDDI Transmission MIB (RFC1512). fddimibSMTConnectionPolicy is simply a
16-bit integer value (ranging from 32768 to 65535) that corresponds to the connection
policy (in the “Reject X-Y” format, where X represents a port on the FDDI Switch
Module, and Y represents the attaching node).
To set the connection policy for the device, total the bit values corresponding to
the desired connection policy according to the table below, and then use your SNMP
Set Request or Mib tool to set the value for the appropriate SMT index. For example,
to set a connection policy that disallowed the undesirable A-A or B-B connections
you would set the fddimibSMTConnectionPolicy MIB OID to 32,801:
32,768 (reject M-M, required) + 32 (reject B-B) + 1 (reject A-A).
