Managing 

Links 

 

Cisco Systems, Inc.

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. 

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
