Blocking and Unblocking Spanning
Tree Explorer Frames
Because the spanning tree does not operate automatically on
source-route bridging circuits, it is necessary to “manually” build the
spanning tree in these circuits. Blockste and Unblockste allow you to
block and unblock the forwarding of spanning tree explorer frames on
source-route bridging circuit groups. This is an alternative to changing
the Block STE configuration parameter in the Configuration Editor and
booting the router to put the change into effect. (Refer to the HP Router
Operator’s Reference.) These commands override the current setting of
the Block STE parameter.
Command Syntax The following example of the Blockste command
demonstrates the conventions used in this table:
blockste circut group
where:
blockste is the command name
circuit group is a required value that you provide
Command Function
Blockste all Block spanning tree explorer frames on all circuit groups in the
router.
blockste circuit group Block spanning tree explorer frames on the specified circuit
group.
Unblockste all Unblock spanning tree explorer frames on all circuit groups in the
router.
unblockste circuit group Unblock spanning tree explorer frames on the specified circuit
group.
