Extreme Networks ExtremeSwitching 5320 Series User Manual

• If the stack supports any feature pack license (such as MPLS or Direct Attach), that
feature pack license must be installed on all primary-capable nodes to support that
feature and to prevent trafc interruption if a failover event occurs.
• Most stacking specic congurations are effective only after a restart. However,
most non-stacking conguration commands take effect immediately and require
no restart.
• A basic stack conguration can be achieved by using the Easy Setup procedure, as
described in the SwitchEngine 32.1 User Guide .
• If EAPS, Spanning Tree, or any Layer 2 redundancy protocol is not running on the
network, make sure that your network connections do not form a network loop.
Follow the recommendations in Recommendations for Placing Switches for Stacked
Operation on page 51 for physically situating your equipment.
Combine Switches from Different Series
5320 Series switches can stack with themselves and 5420 Series switches using
SummitStack-V40 stacking (10G link running at HG). 5320 Series can also be
stacked with 5520 Series switches using Alternate stacking (10Gb link running at
HG). The 5320 Series extended temperature (XT) switches, models 5320-24T-4X-XT
and 5320-24T-24S-4XE-XT, can only stack with themselves using SummitStack-V40
stacking.
Select Stacking Cables
Stacking connections using the native stacking ports require stacking cables that are
specic to the type of stacking port. These cables are available from Extreme Networks
in lengths from 0.5 meter to 100 meters.
Note
For the most recent information about available cables, contact your Extreme
Networks sales representative or refer to the Extreme Optics website.
Caution
Use of non-recommended cables or optics could cause stack instability.
Using the Extreme Stacking Tool
About This Task
The Extreme Stacking Tool provides an easy way to plan your stack. As you select
various switch models and stacking methods, the tool shows you:
• What switch models can be stacked together and which cannot.
• Statistics showing the routing options that are available with every stack
combination.
• Recommendations about which switches should be the primary and backup nodes.
• Information about the supported versions of SwitchEngine for every combination.
