Grouping Popup Menus


The Grouping menu contains functions for creating network elements groups in the topology map. In this menu, you can find options for specifying groups within the topology. These functions are especially helpful when the network is large and contain many devices and elements.

  • Group Selected: The Group Selected Nodes button merges a set of nodes into a single group on the topology map. This is useful if you want to partition the network into groups or hierarchies.

  • Ungroup Selected: This function will ungroup any groups you have selected in the topology window. This permanently removes the group from the system. A group must be collapsed and then selected before this function can be accessed.

  • Ungroup All: This function permanently ungroups all groups in the topology map.

  • Collapse Containing Group: This function will collapse the group containing the selected node, displaying it as a small group symbol with its contents hidden.

  • Collapse All: This function will collapse any groups, displaying them as small group symbols with their contents hidden.

  • Expand All: This function will expand any collapsed group in the topology. The groups are displayed as circular discs and the contents are visible.

  • Expand Selected: This function will expand selected groups.

  • Modify Parent Group of Selected: Moves the selected node from one group to another group of your choice.

  • AutoGroup: This function will allow the program to use its node-grouping algorithm to auto-group nodes. Nodes can be grouped by AS, area, lat/lon, access domain, tree, LAN, hardware type, regular expression, and/or NPA/NXX, depending on what type of network it is. (Options may vary depending upon the hardware type.) You can create more than one grouping levels. If selecting more than one level, the first selection will create the top-most (parent) groups. The second level will subdivide the nodes in a group further into sub-groups, and so forth. For more details, refer to AutoGroup.

  • Sibling Mesh: When this option is selected, a fully-meshed set of lines is drawn among the members of each expanded group. Different groups get different colors.


Select the nodes that you want to autogroup. Next, right-click over the nodes and select Grouping > AutoGroup for the following first level groups. Click AutoGroup only selected instead of all nodes. if you wish to autogroup only the selected nodes.

To create flexible grouping, the “Regexp” button can be used to group according to a regular expression.

  • Look in the field: Indicates the field to use for the match criteria (for example, Node ID, Node Name, IP Address)

  • Find the first match for: Indicates the regular expression that should match in order to form a group.

  • (Optional) Substitute it into: Specifies a name for the new group(s). To create different groups based on the pattern being matched, you can save a part of the expression being matched for into a buffer by surrounding it in parentheses in the “Find the first match for” textbox. Then in the “Substitute it into” textbox, the buffer number can be accessed by preceding it with the ‘$’ symbol. Note that you can have more than one buffer. To create a buffer, surround the expression with a left and right parenthesis. The first buffer in the expression is accessible using $1, the second is accessible using $2, and so forth.

  • Case-sensitive: Specifies whether the string to match is case-sensitive

AutoGroup Examples

Suppose you have routers with the following IDs: P1_ATL, P2_ATL, P3_ATL, P1_NYC, P2_NYC, P3_NYC, P1_CHI, P2_CHI, P3_CHI. Entering either of the criteria in the table below would create the following groups: ATL, NYC, and CHI , each containing 3 routers.

Look in the field

Find the first match for

Substitute it into







If you wish to group the devices only by the first two characters of the ID, the following criteria could be used.

Look in the field

Find the first match for

Substitute it into




Note that local area networks (LANs) not matching the criteria is given a group of their own, such as GROUP0. To move these LANs into the same group as their attached router, select Network Elements > Nodes in the Standard map. Right-click the GROUP0 containing the LANs, and select Grouping>Ungroup this Group. Then right-click the map and select Grouping>Move LANs to Siblings’ Groups.
