2. Convention Appearing in are what is being requested in the request specification. Rspec, results manifests and corresponding table entries are included in text boxes. To view them, put the presentation in slide show mode, and you can use a scroll bar. The textbox control is known not to work on mac versions of PowerPoint. In that case, you can find the files in the tarball sent with the presentation. ig-max

18. Key takeaway Aggregate local store needs to report on inter-aggregate links (so that the collector can have an end-to-end view of the links). As a result: – Interface URNs for switches must match the urn that appears as a “stitch point” in the Aggregate Manager advertisement. These stitch points are the only piece of information that is shared amongst aggregates. – An aggregate local store needs to create interface entries in its ops_interface table for its peer-remote-aggregates interfaces. These remote interfaces entries are not related to nodes (no corresponding entries in ops_node_interface). They have a “stub” role, instead of an “experimental” or “control” role. This allows the collector to identify these “remote” interfaces. – An aggregate local store needs to create interfacevlan entries in its ops_interfacevlan table for each inter-aggregate link endpoint.
