This page explains how chassis resources are reserved, released, and relinquished.
Chassis resource can be either the entire chassis, a test module card on the chassis or a test port on a module. Xena test equipment supports multiple simultaneous connections from any mixture of Xena clients, such as the VulcanManager, scripting clients, etc. As soon as a user/client has successfully established a connection to the chassis, any chassis resource can be inspected. However, in order to change the resource configuration, the resource must first be reserved by the user/client.
Only one client can reserve a particular resource at a time. The reservation will be active even if the client is disconnected. If the client reconnects later and identifies itself with the same username, any such “left- over” reservations will automatically be transferred to the new connection. The reservation belongs to a combination of the connection ID in the chassis and the specified username. The username is simply used as a tag for the reserved resource, and the chassis has no notion of actual “user accounts”. Multiple connections could use the same name, but any resource will only be reserved to one connection at a time. The default username for the VulcanManager is the Windows username for the current user. You can change the username for VulcanManager in the Options menu. The username can contain up to 8 characters.
Reservations are hierarchical exclusive, which means that if user Albert has reserved a given test module then user Bertha will be prevented from reserving any port on that module. The same applies to chassis reservations. However, user Albert does not reserve the ports on the test module by reserving the test module itself.
In general, you do not need to reserve modules and chassis to perform normal traffic generation operations. You should only reserve ports. Reserving modules and chassis are only necessary when performing system maintenance, software upgrades or changing the port types or packet engine allocation on certain ports.
