Command Usage
The command defines the Spanning Tree (STP) function. STP is the older of
STP and RSTP and should only be used if the EFN is used in a context where
collaborating nodes lack RSTP support.
The Spanning Tree (STP) function is relevant only when the EFN switch is
located in a network with alternative or redundant links. For example, when
there are two redundant ‘uplinks’, or when the EFN is one of several daisy
chained switches with an ‘uplink’ at each end of the chain.
Up to 10 different STP configurations may be defined although usually only
one or two are needed. The function is then activated or deactivated on
relevant ports using the add or remove commands specified below.
Setting of
priority
might in exceptional cases be an exception to that rule in
order to affect which node becomes root (the one with lowest value on
priority). In an aggregation network the most central node is the root.
Example:
efn#
set spanning_tree 1 forward_delay 10 hello_time 4
max_age 10
13.8.23 set vlan
Use this command to configure parameters of the switching domains. Use the
command
reset vlan
to reset to default values and
unset vlan
to reset
to undefined values.
