8 Managing Links About this chapter:
This chapter describes how to add and remove a static link between two ports
of two Network Elements in the network. These static links will override any
existing auto-discovered topology in the system. A static link is identical in
all respects to a link that was auto-discovered.
Static links can be viewed using the Topology branch and in the device
topology static key in the relevant Golden Source AVM .xml file.
Creating a Static Link, page 127, describes how to add a static link between
two ports of two Network Elements in the network.
Removing a Static Link, page 131, describes how to delete a dynamic or
static link or all of the links between devices.
8.1 Creating a Static Link
Sheer DNA Manage enables the user to create a static link between devices
by selecting the two end ports from the device’s physical inventory. To create
a static topological link the user needs to supply the exact location of the two
end ports (at both ends of the link). The physical hierarchy in which the port
is located defines the location of a port, as follows:
Device →[shelf] → module → [submodule] → port
Note: The link is bi-directional and therefore only needs to be added once.
The new link is validated after the two ports are selected, but before the link
is added. Validation checks the following:
• The similarity of the connector port types (for example, RJ45 on both
sides)
• Layer 2 technology type (for example, ATM OC-3 on both sides)
• The physical layer
• The operation status of both ports
• If one of the ports is part of another link
