VSM CLI Tree Node Commands
vsm
Syntax [no] vsm
Context config
Description This command changes the current CLI context to the CCA nodal context. The CCA nodal context is
where CCAGs are created and maintained.
The CCA nodal context always exists and cannot be removed.
ccag
Syntax ccag ccag-id [create]
no ccag ccag-id [force]
Context config>vsm
Description This command creates a Cross Connect Aggregation Group (CCAG). A CCAG represents a group of
CCAs as a common forwarding entity. Objects requiring a CCA cross connect function are mapped to
a CCAG, not the individual CCAs within the CCAG. The CCAG treats each active member CCA as a
possible destination when forwarding packets between the cross connected objects mapped to the
CCAG. The system uses both conversation hashing functions and direct service mappings to
determine the load sharing distribution between the active CCAs. All packets for a given conversation
flow through the same CCA to preserve packet order. Packet ordering may be momentarily affected
during convergence events when CCAs are dynamically added or removed from the active list.
The CCAG context is used to manage the following functions per CCAG instance:
• Informational description of the CCAG
• Administrative state of the CCAG
• Alpha path bandwidth and weight parameters
• Beta path bandwidth and weight parameters
• CCA total bandwidth limit
• CCA membership in the CCAG
The no form of the command removes an existing ccag-id from the system. Once the specified ccag-
id is removed from the system, it may not be referenced by any cross connect objects. If the force
keyword is not specified, the no ccag ccag-id command will fail if the specified ccag-id has one or
more cc-ids associated with it. In the event that the specified ccag-id does not exist, the no ccag ccag-
id command will return to the current CLI context without any change to the system.
Default None (each CCAG context must be explicitly created to be used)
