Features Benefits
Single IP address management Stack up to 8 switches as a single “chassis” logical unit
One GUI and one CLI managing the whole stack
The stack acts as a single switch in the network
The other switches in the network also see the stack as a single switch
Growth is easy, adding a switch to the stack is as simple as connecting the new unit to the stack (con guration
is instantly updated)
Bi-directional architecture
48 Gigabit local stacking capacity per switch using
AX742 stacking kit
40 Gigabit distant stacking capacity using AX743 +
AXM761/AXM762/AXM763 (SFP+ optics)
Higher stacking throughput capacity with lower latency and jitter for VoIP and video traf c
Each switch in the stack understands the shortest path to forward traf c, bi-directionally both up and down
Vertical/local stacking and horizontal/distant stacking can be mixed for convenient 10 Gigabit deployments
(core, distribution layer, edge)
Stack resiliency
Automatic unit replacement (AUR)
Dual ring architecture ensures that if a switch fails within the stack all the other switches can still communicate
with one another
Adding a new switch to the stack or replacing a failed unit requires no service interruption, the con guration
le is pushed automatically by the stack
Distributed trunking across the stack (link aggregation
groups, LACP)
Increased performance with distributed trunks to the core
Greater redundancy using trunking as several switches are connected to the trunk
(up to 8 ports per trunk – 64 trunks are allowed)
Many-to-one port mirroring across the stack More exibility for device troubleshooting
As for a chassis, port mirroring is available from every port to every port across the stack
VLANs automatic propagation across the stack As for a chassis, VLAN port tagging or private groups are available everywhere across the stack as for a
single switch (Unit 1, Port 2; Unit 2, Port 3, etc.)
• No con guration required for the VLAN propagation between the switches
Flexible stacking with non-PoE switches Stacking with GSM7328S/GSM7352S/GSM7328FS
Mixing PoE and non-PoE ports into a single logical unit
Versatile deployment options
Stacking with GSM7328S/GSM7352S/GSM7328FS Note
Stackable, PoE L2+ Managed Gigabit Switches GSM7228PS and GSM7252PS are exible enough to integrate GSM73xxS stack con gurations in full Layer 3 mode without
L3 License Upgrade.
When integrating a GSM73xxS stack, the GSM7228PS/GSM7352PS will bene t from the Layer 3 stack full feature set, as slaves within the stack.
Only the stack master determines the stack con guration/feature set. If the stack master is a GSM73xxS then the entire stack pro ts from the master L3 con guration.
Without Layer 3 license upgrade, if a GSM7228PS/GSM7252PS becomes the master, then the entire stack will downgrade to Layer 2+ feature set. Unless Layer 2+ is the
preferred feature set, it is advised to determine in advance which other Layer 3 GSM73xxS slave would become the stack master in case of the stack master failure, by
specifying the secondary stack master settings in the stack con guration.
With a Layer 3 license upgrade, a GSM7228PS/GSM7252PS can become the master and handle the full stack L3 con guration.
