Effective range of a BCAM command

The BCAM commands

• BCACT

• BCDAC

• BCIN

• BCOUT

• DCOPT

• DCSTART

implement the activate, initialize, deactivate, and terminate functions for a single object or a set of objects. The objects are split into groups for this purpose.
To define the groups, the network is viewed as a tree-like structure with four hierarchical levels, see the figure see section "Effective range of a BCAM command". The host forms the root of the structure.

The more recent BCAM-SDF commands

• ACTIVATE-LINE

• ACTIVATE-LINK-AGGREGATION

• ACTIVATE-VLAN-DEVICE

• ACTIVATE-VLAN-LINE

• DEACTIVATE-LINE

• DEACTIVATE-LINK-AGGREGATION

• DEACTIVATE-VLAN-DEVICE

• DEACTIVATE-VLAN-LINE

on the other hand specifically affect the objects to be processed.

The commands are only executed for objects that are known to BCAM.
This means that various groups of objects can be addressed, depending on the object specified in the command.
The object name, its designation, and the scope of the command are specified in the corresponding BCAM command. This defines the group of objects to which this command is to apply. If the command executes two functions, a hierarchical level must be specified for each individual function.

  
Example

/BCIN PROCESSOR=<processor-name>,INI=ALL,ACT=LOCAL

or

/BCACT NODE=<node-name>,ACT=ONLY 

Each function executed is reported and acknowledged.

Object addressed in command	Parameter value	Scope of command
(Virtual) host	ONLY	(Virtual) host
	LOCAL	(Virtual) host Line connections exclusively assigned to the host Routes to locally connected end systems Routes to locally connected front-end processors (FEPs) Locally connected LAN nodes
	NODE	(Virtual) host Line connections exclusively assigned to the host Routes to locally connected end systems Routes to locally connected front-end processors (FEPs) Locally connected LAN nodes Routes to end systems directly connected to LAN nodes
	ALL	(Virtual) host Line connections exclusively assigned to the host Routes to locally connected end systems Routes to locally connected front-end processors (FEPs) Locally connected LAN nodes Routes to end systems directly connected to LAN nodes Routes to end systems that can be reached via routers
LAN nodes	ONLY LOCAL	LAN nodes Associated line connections
	NODE	LAN nodes Associated line connections Routes to end systems directly connected to LAN nodes
	ALL	LAN nodes Associated line connections Routes to end systems directly connected to LAN nodes Routes to end systems that can be reached via routers connected to the LAN nodes
Router	ONLY LOCAL	Router All routes to the router
	ALL	Router All routes to the router Routes to end systems that can be reached via the router
Remote end system		End system All routes to the end system
Route		Route End system if the last or only route to the end system is addressed
Line connection		Line connection

The BCAM-SDF commands are only executed for objects which are known to BCAM. Depending on the object specified in the command you can address different groups of objects in this way.
The name of the object is specified in the corresponding BCAM-SDF command.

Each function which is executed is reported and acknowledged.

Object addresses in command	Scope of command
Link aggregation	Link aggregation
Line connection	Activates: Line connection Deactivates: Line connection
VLAN device	Activates: VLAN device Deactivates: VLAN device VLAN lines which are connected to the VLAN device
VLAN lines	Activates: VLAN device VLAN line Deactivates: VLAN line VLAN device if the last VLAN line to this VLAN device is concerned
