GigaStream Rules and Maximums

The following rules apply to regular GigaStream and controlled GigaStream:

GigaStream Rule	Description
Port Location	All participating ports must be on the same GigaVUE node. On the GigaVUE‑HC2 and GigaVUE‑HC3, GigaStream can be across modules.
Speed Requirements	■   All participating ports must be running the same speed (1Gb, 10Gb, 40Gb. or 100Gb) and must use the same port types (for example, all g, x, q, or c). ■   A stack GigaStream must consist of ports with 10Gb speed or higher. ■   The system will not let you change the speed of any port participating in a tool GigaStream. Keep in mind that the only ports that allow speed changes through are gx ports. ■   You can use gx ports in a regular tool GigaStream, but only with ports running at the same speed (and no slower than 1000Mb).
Addressing	Once a port belongs to a GigaStream, it must be addressed by its GigaStream alias. It can no longer be addressed as an individual port. For example, if tool port 1/1/x4 is part of a tool GigaStream, the GigaVUE H Series node prevents you from using it as the destination for a map rule.
Stack Ports	Stacking ports must be 10Gb or higher. Therefore, the Maximum Stack Ports per GigaStream for any 1Gb port is N/A in : Maximum Ports per GigaStream to.GigaStream Rules and Maximums
SFP+	For SFP+ ports that can operate at 10Gb or 1Gb, refer to the values in the Maximum Tool Ports per GigaStream column for the 10Gb Ports rows in : Maximum Ports per GigaStream to GigaStream Rules and Maximums.

For GigaStream maximums, refer to Maximum Ports per GigaStream, which have been updated in software version 5.1.

Maximum Ports per GigaStream

Table 1: : Maximum Ports per GigaStream lists the maximum ports per GigaStream for GigaVUE nodes.
