Features and benefits
Quality of Service (QoS)
•
Powerful QoS feature:
creates traffic classes
based on access control lists (ACLs), IEEE 802.1p
precedence, IP, DSCP or Type of Service (ToS)
precedence; supports filter, redirect, mirror, or
remark; supports the following congestion actions:
strict priority (SP) queuing, weighted round robin
(WRR), weighted fair queuing (WFQ), weighted
random early discard (WRED), weighted deficit
round robin (WDRR), and SP+WDRR
•
Integrated network services:
with support for
open application architecture (OAA) modules,
extends and integrates application capability into
the network
•
Ring Resiliency Protection Protocol (RRPP):
provides fast recovery for ring Ethernet-based
topology; ensures consistent application
performance for applications such as VoIP
Management
•
Remote configuration and management:
is
available through a secure Web browser or a
command-line interface (CLI)
•
IEEE 802.1ab LLDP discovery:
advertises and
receives management information from adjacent
devices on a network
•
USB support:
–
File copy:
allows users to copy switch files to
and from a USB flash drive
•
DHCP options:
server (RFC 2131), client,
snooping, and relay
•
SNMPv1, v2c, and v3:
facilitate centralized
discovery, monitoring, and secure management of
networking devices
•
sFlow:
provides scalable, ASIC-based, network
monitoring and accounting; this allows network
operators to gather a variety of sophisticated
network statistics and information for capacity
planning and real-time network monitoring purposes
•
Network Time Protocol (NTP):
synchronizes
timekeeping among distributed time servers and
clients; keeps consistent timekeeping among all
clock-dependent devices within the network so that
the devices can provide diverse applications based
on the consistent time
Connectivity
•
High-density port connectivity:
194 10-GbE
ports with a 40 Gbps resilient backplane
•
Data center I/O consolidation:
the
A5820-14XG FCoE module supports two 4x8/4/2
Gbps FCoE modules (up to eight FC ports total) to
reduce cost and complexity while boosting network
performance
•
Auto-MDIX:
automatically adjusts for
straight-through or crossover cables on all 10/100
and 10/100/1000 ports
•
Jumbo frames:
on Gigabit and 10-Gigabit ports,
allow high-performance remote backup and
disaster-recovery services
•
IPv6 native support:
–
IPv6 host:
enables switches to be managed and
deployed at the IPv6 network's edge
–
Dual stack (IPv4/IPv6):
transitions from IPv4
to IPv6, supporting connectivity for both protocols
–
MLD snooping:
forwards IPv6 multicast traffic to
the appropriate interface
–
IPv6 ACL/QoS:
supports ACL and QoS for IPv6
network traffic, preventing traffic flooding
–
IPv6 routing:
supports IPv6 static routes and
IPv6 versions of RIP, OSPF, IS-IS, Border Gateway
Protocol (BGP) routing protocols
Performance
•
Hardware-based wire-speed access control
lists (ACLs):
feature-rich ACL implementation
(TCAM based) helps ensure high levels of security
and ease of administration without impacting
network performance
•
Unique Flex Chassis Architecture:
supports the
best of both fixed chassis and modular
configurations
•
Cut-through switching:
delivers wire-speed,
line-rate performance on all ports, as well as
cut-through switching for low latency
Manageability
•
Full-featured console:
provides complete control
of the switch with a familiar command-line interface
(CLI)
•
Web interface:
allows configuration of the switch
from any Web browser on the network
•
RMON and sFlow:
provide advanced monitoring
and reporting capabilities for statistics, history,
alarms, and events
•
Multiple configuration files:
allow multiple
configuration files to be stored to flash image
