Port Groups

The Port Groups selection in the top navigation bar provides access to the All Port Groups and GigaStream pages, for creating port groups and GigaStreams, respectively.

All Port Groups

Selecting All Port Groups under Port Groups opens the Ports Group page by default. This page is used to create a port group, which can simplify administration of GigaVUE ports. Administrators can create groups of ports that can then be quickly assigned to different user groups. With clustered ports potentially numbering into the hundreds, port groups provide a useful shorthand when assigning multiple ports to different user groups. (To create user groups, select Roles and User from the navigation pane, and refer to Managing Roles and Users” in the GigaVUE Administration Guide for more details.) The following are the different types of port groups:

■   Network Port Group—contains only network ports.
■   Tool Port Group—contains only tool ports or tool GigaStream, which is a combination of multiple tool ports.
■   Hybrid Port Group—contains only hybrid ports or hybrid GigaStream, which is a combination of multiple hybrid ports.
■   Circuit Port Group—contains only circuit ports or circuit GigaStream, which is a combination of multiple circuit ports.
■   Load Balancing Port Group—contains tool ports for load balancing. The maximum number ports allowed for port load balancing is 16.

However, port groups that include GigaStream can only be used with GTP Overlap Flow Sampling maps. For more information about GTP Flow Sampling, GTP Whitelisting and GTP Overlap Flow Sampling maps, refer to GigaSMART GTP Whitelisting and GTP Flow Sampling.


Selecting GigaStreams under Port Groups, opens the GigaStreams page. A GigaStream is a bundle of multiple ports on a GigaVUE‑OS node used for stacking, tool ports. The following are the types of GigaStream you can create:

■   Tool GigaStream—It is a bundle of multiple tool ports used as a single logical group. This type of GigaStream as a single addressable destination, allowing you to overcome tool port oversubscription issues.
■   Hybrid GigaStream—It is a bundle of multiple hybrid ports that are combined into a single logical group in all H Series nodes.
■   Stack GigaStream—It is a bundle of multiple stack ports used as a single logical group. Stack-links can use GigaStream to distribute data between multiple H Series nodes operating in a cluster. With the number of 10Gb/40Gb/100Gb ports possible in a GigaVUE HC Series chassis, using only one 10Gb port for a stack-link could cause a serious bottleneck. A GigaStream dramatically increases the bandwidth available for stack-link connections, letting you connect H Series nodes in a cluster and still take advantage of the 10Gb port density.
■   Circuit GigaStream—It is a bundle of multiple circuit ports that are combined into a single logical group. The circuit ports send or receive traffic that is tagged with the circuit ID.
■   Controlled GigaStream

Controlled GigaStream provides more control of the traffic stream by specifying the size of a hash table and allowing the assignment of hash IDs to the ports in a GigaStream. This makes it possible to keep the hashing algorithm from reapplying the algorithm to the ports if one of the ports in the GigaStream goes down.
