Performance
-
Architecture: up to 76.8 Gbps crossbar switching fabric provides wire-speed intra- and inter-module switching with up to 48 million pps throughput built on ProCurve custom-designed ASIC technology
Resiliency and high availability
-
Router redundancy (XRRP): allows groups of two routers to dynamically back each other up to create highly available routed environments
-
IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees
-
IEEE 802.1w Rapid Convergence Spanning Tree Protocol: increases network uptime through faster recovery from failed links
-
IEEE 802.3ad Link Aggregation Control Protocol (LACP) and ProCurve trunking: support up to 36 trunks, each with up to 8 links (ports) per trunk; trunking across modules is supported
-
Hot-swappable modules: permit modules, mini-GBICs, and one of the power supplies in a redundant power supply configuration to be added or swapped without interrupting the network
-
Optional redundant power supply: provides uninterrupted power; allows hot-swapping of one of the two supplies when installed
Layer 2 switching
-
ProCurve switch meshing: dynamically load-balances across multiple active redundant links to increase available aggregate bandwidth
-
VLAN support and tagging: support complete IEEE 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously
-
IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs
-
GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
Layer 3 services
-
UDP helper function: UDP broadcasts can be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevent server spoofing for UDP services such as DHCP
Layer 3 routing
-
Layer 3 IP routing: provides routing of IP at media speed; supports static routes, RIP, RIPv2, and OSPF
-
OSPF-ECMP: enables multiple equal-cost links in OSPF environment to increase link redundancy and scale bandwidth
Security
-
Virus throttling: detects traffic patterns typical of WORM-type viruses and either throttles or entirely prevents the ability of the virus to spread across the routed VLANs, without requiring external appliances
-
ICMP throttling: defeats ICMP denial-of-service attacks by enabling any switch port to automatically throttle ICMP traffic
-
Multiple user authentication methods:
-
IEEE 802.1X industry-standard way of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
-
Web-based authentication similar to IEEE 802.1X, provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant
-
MAC-based authentication client is authenticated with the RADIUS server based on the client's MAC address
-
Authentication flexibility:
-
Multiple IEEE 802.1X users per port provides authentication of multiple IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
-
Concurrent IEEE 802.1X and Web or MAC authentication schemes per port switch port will accept any of IEEE 802.1X and either Web or MAC authentications
-
Access control lists (ACLs): provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
-
Identity-driven ACL: enables implementation of a highly granular and flexible access security policy specific to each authenticated network user
-
Port security: allows access only to specified
MAC addresses, which can be learned or
specified by the administrator
-
MAC address lockout: prevents configured particular MAC addresses from connecting to the network
-
Source-port filtering: allows only specified ports to communicate with each other
-
TACACS+: eases switch management security administration by using a password authentication server
-
Secure Shell (SSHv2): encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks
-
Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
-
Secure FTP: allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file
-
Secure access to manage the ProCurve Switch 5300xl series: all access methods--CLI, GUI, or MIB--are securely encrypted through SSHv2, SSL, and/or SNMPv3
-
Switch management logon security: can require either RADIUS or TACACS+ authentication for secure switch CLI logon
Convergence
-
IP multicast routing (PIM Dense): routes IP multicast traffic using the PIM Dense routing protocol
-
IP multicast snooping and data-driven IGMP: automatically prevents flooding of IP multicast traffic
-
LLDP-MED (Media Endpoint Discovery): a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones
Quality of Service (QoS)
-
Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers
-
Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into 8 priority levels mapped to 4 queues
-
Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), L3 protocol, TCP/UDP port number, source port, and DiffServ
-
Bandwidth shaping:
-
Rate limiting per-port ingress-based enforced bandwidth maximums
-
Guaranteed minimums per-port, per-queue egress-based guaranteed bandwidth minimums
Manageability
-
User-driven port configuration support: switch port configuration responds to RADIUS-stored user attributes for QoS and rate limiting when that user authenticates; these attributes are then determined by the user, not the switch port
-
RMON, XRMON, and sFlow: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
-
IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications
-
Friendly port names: allow assignment of descriptive names to ports
-
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
-
Dual flash images: provides independent primary and secondary OS and configuration files for backup while upgrading or fine-tuning the switch configuration
-
Multiple configuration files: allow a config file to be stored for each flash image
-
Troubleshooting: ingress/egress port monitoring enables network problem-solving
-
Custom banner: displays security policy when users log in to the switch
