Additional Information; Warranty And Support - HP A5820 Switch Series Datasheet

• Port security: allows access only to specified
MAC addresses, which can be learned or specified
by the administrator
• MAC-based authentication: allows or denies
access to the switch based on client MAC address
• IP source guard: helps prevent IP spoofing
attacks
• HTTPS management: provides secure Web
management
• URPF: limits malicious traffic on a network
• Multi-Customer Edge (MCE)-Multicast
Virtual Routing and Forwarding (MVRF):
provide MPLS Edge router support
• Public Key Infrastructure (PKI): is used to
control access
Convergence
• Voice VLAN: automatically assigns VLAN and
priority for IP phones, simplifying network
configuration and maintenance
• LLDP-MED: is a standard extension that
automatically configures network devices, including
LLDP-capable IP phones
• Internet Group Management Protocol
(IGMP): is used by IP hosts to establish and
maintain multicast groups; supports v1, v2, and v3;
utilizes Any-Source Multicast (ASM) or
Source-Specific Multicast (SSM) to manage IPv4
multicast networks
• Protocol Independent Multicast (PIM): is used
for IPv4 and IPv6 multicast applications; supports
PIM dense mode (DM), sparse mode (SM), and
source-specific mode (SSM)
Monitor and diagnostics
• Port mirroring: enables traffic on a port to be
simultaneously sent to a network analyzer for
monitoring
• OAM (802.3ah): detects data link layer problems
that occurred in the "last mile"; monitors the status of
the link between the two devices
• CFD (802.1ag): connectivity fault detection (CFD)
provides a Layer 2 link OAM (operations,
administration, and maintenance) mechanism used
for link connectivity detection and fault locating

Additional information

• Intelligent Resilient Framework (IRF):
– Creates virtual resilient switching fabrics, where
two or more switches perform as a single Layer 2
switch, and Layer 3 router
– Switches do not have to be co-located and can be
part of a disaster recovery system
– Servers or switches can be attached using
standard LACP for automatic load balancing and
high availability
– Simplifies network operation by eliminating the
complexity of Spanning Tree, ECMP, or VRRP
• OAA modules: support wireless network
management and high-performance security
applications; leverage network infrastructure
investment
• Green IT and power: use the latest advances in
silicon development, shut off unused ports, and use
variable-speed fans to improve power efficiency
