HP ProCurve Switch 5300xl Series Reviewer’s Guide
2. Evaluation Features and Benefits
2.1 Feature Set Summary
The HP ProCurve Switch 5300xl Series are store-and-forward Layer 2/3/4 routing switches. Features,
discussed in more detail later in this section, include:
2.1.1 Architecture
•
A high speed Layer 3 architecture consisting of a full routing switch ASIC on each module, all
interconnected via the backplane crossbar switch fabric ASIC. Both ASICs are HP designed. Up
to 16,536 (16K) L2 MAC addresses are supported.
2.1.2 High Availability
•
IP Functionality supported:
ƒ Routing services: RIP (v1, v1 compatible v2, and v2), OSPF, static routes
ƒ 10,000 network address routes, 65,536 (64K) L3 host address routes
ƒ IPv4 routing, IPv6 switching
ƒ 16 multi-netted interfaces per VLAN
ƒ DHCP relay – allows DHCP requests to be forwarded to links associated with the DHCP
server
•
IEEE 802.1w Rapid Spanning Tree Protocol support – provides very fast Spanning Tree
convergence (approaching 1 second under optimal conditions) on lost links or when the
root switch is unreachable. Compatible with switches running 802.1D Spanning Tree.
•
XRRP Router Redundancy Protocol: Two 5300s can back each other up for Layer 3 interfaces.
Failure detection and switch-over can be as fast as 3 seconds.
•
HP Layer 2 Switch Meshing: Allows fully meshed connections between switches at Layer 2 with
all links being used to send traffic.
2.1.3 Prioritization / QoS
•
Four priority queues
•
Traffic prioritization based on:
•
UDP/TCP Application Type (port number)
•
Device Priority (destination or source IP address)
•
IP Type of Service (ToS/Diffserv) field (IP packets only)
•
Protocol Priority (IP, IPX, ARP, DEC LAT, AppleTalk, SNA, and NetBEUI)
•
VLAN Priority
•
Incoming source-port on the switch
•
Incoming 802.1p Priority (present in tagged VLAN environments)
2.1.4 Security
•
Filtering capabilities include Access Control Lists (ACLs), source port, multicast MAC address
and protocol filtering capabilities.
•
802.1x – port based access control
•
RADIUS / authentication
