Figure 160: Combining Stacking Port Types: Example

Note

The ﬁgure is intended to show cable connections between switches. Details of the switches

themselves, such as the location of the stacking ports and fan modules, might dier from

those of the switches that actually would be used.

The following cables are used to make the stacking connections:

• QSFP+ cable connecting the two switches at the top (slot 1 and slot 2)

• SFP+ cable connecting the switch in slot 2 with the switch in slot 3

• SFP+ cable connecting the switch in slot 3 with the switch in slot 4

• SFP+ cable connecting the switch in slot 4 with the switch in slot 5

• SFP+ cable connecting the switch in slot 5 with the switch in slot 1

Table 98 lists the recommended order for connecting the stacking ports in this example.

Use SummitStack-V160 Stacking

A stacking rate of 160 Gbps can be achieved using certain conﬁgurations of Extreme Networks

switches. For example, an X460-G2 switch can be connected to an X670-G2-48x-4q switch through

40-Gbps stacking connections that provide 160 Gbps full-duplex bandwidth. This connection is

performed using the VIM-2q module in the X460-G2 switch and the QSFP+ ports on the X670-

G2-48x-4q switch.
