Extreme Networks Data Sheet: Summit X150 Series
Voice-Class Availability
Powered by ExtremeXOS, the Summit X150 switch supports process recovery and application upgrades without the
need for a system reboot. Summit X150 offers the high network availability required for converged applications.
need for a system reboot. Summit X150 offers the high network availability required for converged applications.
Link Aggregation (802.3ad)
Link aggregation allows trunking of up to eight links on a single
logical connection, for up to 2 gigabits per second (Gbps) of
redundant bandwidth per logical connection.

Exceptional Policy-based QoS with
Advanced Traffic Management for
Converged Applications
Summit X150 provides eight hardware queues per port to
support granular traffic classification with bandwidth
allocation. The 1,024 centralized classifiers per 24-port block
can use information from Layers 1 through 4 to prioritize and
meter incoming packets at line-rate. When metering traffic, the
switch can drop out-of-spec traffic or flag it for later action. To
expedite upstream traffic handling, a packet’s classification can
be carried forward with Layer 2 (802.1p) and Layer 3 (Diffserv)
markings. Summit X150 switches provide advanced traffic
management features that support high-quality triple play of
voice, video and data services.

Redundant Power Supplies
Summit X150 switches provide an optional external redundant
power supply which offers a convenient and easy-to-upgrade
in-field option to protect against power anomalies.

Modular Operating System to Help
Maximize Uptime
Preemptive Multitasking and Protected
Memory
Summit X150 switches allow each of many applications—such
as Spanning Tree Protocol (STP)—to run as separate operating
system processes that are protected from each other. This
drives increased system integrity and helps protect against
Denial of Service (DoS) attacks.

Process Monitoring and Restart
ExtremeXOS improves network availability using process
monitoring and restart. Each independent operating system
process is monitored in real time. If a process becomes
unresponsive or stops running, it can be automatically
restarted.

Loadable Software Modules
The modular design of ExtremeXOS allows the upgrading of
individual software modules, should this be necessary, leading
to higher availability in the network (see Figure 1).

High Availability Network Protocols
Ethernet Automatic Protection Switching
(EAPS)
EAPS allows the IP network to provide the level of resiliency
and uptime that users expect from their traditional voice
network. EAPS differs from Spanning Tree and Rapid Spanning
Tree protocols offering sub-second (less than 50 milliseconds)
recovery that helps deliver consistent failover regardless of the
number of VLANs, network nodes or network topology. Since
EAPS allows the network to recover almost transparently, VoIP
calls will not drop and digital video feeds will not freeze or
pixelize in most situations.

Spanning Tree/Rapid Spanning Tree
Protocols
Summit X150 switches support Spanning Tree (802.1D), Per
VLAN Spanning Tree (PVST+), Rapid Spanning Tree (802.1w)
and Multiple Instances of Spanning Tree (802.1s) protocols for
Layer 2 resiliency.
