Groups of redundant lines to a node

Also groups and subgroups of redundant lines can be created with BCAM, thereby enhancing the definition of redundant configurations. This enables you to specify precisely which lines to a node are to be regarded as redundant and which lines are not to take part explicitly in a switchover. Groups of lines which are redundant among themselves can thus be formed on a node. The subgroup is used to control which lines are to be used preferentially as alternatives.

This group formation is defined by a simple extension to the CREATE-LINE and CREATE-VLAN-LINE commands.

The figure below shows the extended concept of redundancy with group formation:
