Building Stacks
•
Only the master and master-capable nodes require a license to support special features such as
MPLS (Multiprotocol Label Switching).
•
If the MPLS feature pack is installed on the master-capable nodes, the following guidelines apply:
◦ Every switch in the stack must meet the software and hardware requirements listed in the
Feature License Requirements document.
◦ Only the enhanced stacking protocol is supported for the X460-G2 switch. Every node that
shares a stack with an X460-G2 switch must have enhanced stacking configured.
◦ We recommend against mixing X450-G2, X460-G2, and X670-G2 switches in a stack.
◦ Summit X460-G2 switches support multiple types of QSFP+ stacking cables for connection
between VIM-2q ports and QSFP+ ports on other Summit switches. For information on which
cables to use with each type of Summit family switch, see
209.
◦
The last two front panel 10G ports are used for alternate stacking (SummitStack-V feature).
◦
VIM-2q ports are used for SummitStack-V160G stacking.
◦
VIM-2t ports are not used for stacking. These ports are used for user data.
◦
A VIM-2q module attached to an X460-G2 switch supports LR4 PSM in 40G mode.
◦
The X460-G2 switch supports the LR4 Parallel Single Mode (PSM) optical transceiver on 40G
optical QSFP+ ports.
◦ The LR4 PSM is supported on the following platforms: X440-G2, X450-G2, X460-G2, X620,
X670-G2.
Summit X460-G2 (1G Models Using VIM Ports) Stack Configuration Guidelines
Before deploying a new stack with Summit X460-G2 1-gigabit switch models (GE4), consider the
following guidelines:
•
SummitStack-V stacking is supported through an attached VIM: VIM-2x, VIM-2q, or VIM-2ss.
•
We recommend against mixing X450-G2, X460-G2, and X670-G2 switches in a stack if the desired
routing table exceeds the supported limit.
•
Support is available on ExtremeXOS version 16.1 or later.
ExtremeSwitching X465 Stacking
