Summit 300 Series Product Brief

Redundant copper and fiber gigabit 
uplinks, dual-homed configurations, and 
sub-second EAPS failover provide mission-
critical resiliency. The Summit 300 delivers 
advanced high availability features 
traditionally reserved for carrier networks. 
Ethernet Automatic Protection Switching 
(EAPS, RFC 3619) delivers sub-second 
(less than 50ms recovery) protection 
switching to interconnected switches in 
an Ethernet ring topology. Similar to the 
Spanning Tree Protocol (STP), EAPS 
offers the advantage of converging in 
significantly less time than STP or even 
Rapid Spanning Tree (802.1w) when a 
link breaks in the ring. Extreme Standby 
Routing Protocol™ (ESRP) can be 
implemented at both Layers 2 and 3 and 
extends the Virtual Router Redundancy 
Protocol’s (VRRP) capabilities, adding 
Layer 2 resiliency and loop prevention 
and Layer 3 default router redundancy. 
It can be used as a STP substitute and 
can be scaled to protect thousands of 
VLANs. Multiple instances of ESRP in the 
same VLAN allow direct host attachment 
to standby switches.

The Summit 300 series offers a number of 
features that improve the performance of 
the network, such as RIP, OSPF, Network 
Address Translation, QoS classification, 
dynamic VLANs, and Access Control 
Lists. For converged applications involving 
voice or rich media, the switch provides 
multicast, re-writing 802.1p tag prioriti-
zation, or prioritization using Layers 2 – 4. 
Four hardware queues per 10/100 port 
provide granularity and guarantee low 
latency and low jitter for time-sensitive 
voice and multi-media applications. These 
applications also benefit from features 
such as DiffServ and 802.1p which deliver 
varied levels of service and ensure efficient 
bandwidth usage.

Enterprise networks need both Layer 2 
and Layer 3 intelligent services at the edge 
to ensure maximum network efficiency. 
Intelligence supports critical functionality 
such as security to prevent unauthorized 
access, high availability to ensure network 
uptime, and common management to 
reduce expenses.

Security is a paramount concern in today’s 
converged networks. ExtremeWare 
supports multiple authentication options 
including 802.1x, web-based login with 
SSL, and MAC address. With IEEE 802.1x 
login, network managers can always 
control who is accessing and connected 
to the network. Web-based Network 
Login offers the freedom of authenticat-
ing through any HTTP-compliant web 
browser. MAC address security prevents 

unauthorized port abuse from rogue 
wireless APs or hubs/switches on edge 
ports. Port abuse can be reduced using 
lockdown on a per port basis and/or 
limiting of the number of MAC addresses 
learned by a port. Limiting the number of 
MAC addresses learned on a port also 
allows enforcement of service level 
agreements in tenant or service provider 
environments. MAC address security can 
also be used in conjunction with a 
RADIUS server to allow devices such as 
bar code readers that do not support 
802.1x to enter the network based on 
their MAC address.

AccessAdapt technology provides 
centralized configuration and software 
delivery to Altitude 300 wireless ports. 
Altitude 300 APs receive their personal-
ity from the switch. This simplifies 
management and enables secure moves 
or changes to APs.
