Filters > Protocols

 

The Subviews > Protocols pane offers the ability to display subsets of the available network routing protocols in the network using logical operations like AND, OR, NOT, and EQUAL. The selections available will vary according to the protocols in the open network

The bottom of the pane contains the number of nodes, pseudo-nodes, groups, and links that are currently displayed out of the total number. The number displayed is less than the total when objects are hidden due to selections either in this pane or other Filters panes.

Show, Not



Selecting Show by itself for a protocol displays all network elements supporting the protocol. Selecting Show and Not together for a protocol displays all network elements that do not support the protocol.



Logical Operations (=, &, and or)



You can perform logical operations on the protocol list selections. The equal operation (=) specifies that only the currently selected subview is shown. Only one selection is allowed for this operation. The AND operation (&) specifies that the intersection of the protocol subviews is displayed. The OR operation (or) specifies that the union of the protocol subviews is displayed. lists the logical operations.
