Key Features and Benefits
Comprehensive QoS
The AS5812-54X-EC/54T-EC offers advanced QoS for marking,
classification, and scheduling to deliver best-in-class performance for
data, voice, and video traffic at wire speed. Eight egress queues per
port enable differentiated management of up to eight traffic types
through the switch.
Traffic is prioritized according to 802.1p and DSCP to provide optimal
performance for real-time applications. Weighted Round Robin (WRR)
and strict priority ensure differential prioritization of packet flows and
avoid congestion of ingress and egress queues.
Asymmetric bidirectional rate-limiting per port or per traffic class,
preserves network bandwidth and allows maximum control of network
resources.
AS5812-54X-EC/54T-EC supports Three Color Marker and Policing
Single rate: Committed Information Rate (CIR) Two rate: CIR + Peak
Information Rate (PIR) Traffic Policing: The switch drops or remarks the
priority tags of packets when they exceed the burst size.
Robust Multicast Control
IGMP snooping prevents the flooding of multicast traffic by dynamically
configuring switch ports so that multicast traffic is forwarded to only
those ports associated with an IP multicast receiver. IGMP snooping
increases the performance of networks by reducing multicast traffic
flooding.
IGMP groups allow you to create customer packages for IP-TV
channels, making switch configuration easy. IGMP Filtering prevents
subscribers seeing unsubscribed IP-TV channels. And, IGMP
Throttling allows you to set how many IP-TV channels a subscriber can
receive simultaneously.
IPv6 Support
The switch supports a number of IPv6 features, including IPv6
Management, DCHPv6 Snooping with Option 37, IPv6 Source Guard.
Superior Management
An industry-standard command-line interface (CLI), accessed through
the console port or Telnet, provides a familiar user interface and
command set for users to manage the switch.
An embedded user-friendly web interface helps users to quickly and
simply configure switches.
The AS5812-54X-EC/54T-EC supports SNMPv1,2c,3 and four-group
RMON. The switch provides a complete private MIB for the
configuration of most functions via the SNMP protocol.
Administrators can backup and restore firmware and configuration files
via TFTP or FTP. The switch also provides the configuration of
auto-provision for ease of use in large deployments.
AAA (Authentication) via RADIUS, TACACS+, enables centralized
control of the switches.
Service Monitoring and Management
The AS5812-54X-EC/54T-EC supports IEEE 802.1ag and ITU-T Y.1731,
allowing service providers to monitor end-to-end services, identify
connectivity and performance issues, and isolate problems from a
remote location without dispatching an engineer onsite.
The switch also provides the capability to monitor service availability,
delay, jitter, and dropped packets for verifying SLA conformance (for
billing purposes) and providing advance indication of performance
degradation before a service outage occurs.
Virtual Private Networks
The AS5812-54X-EC/54T-EC supports Layer 2 VPNs by using Q-in-Q
functions, where an 802.1Q tag from a customer VLAN (called
CE-VLAN ID) is encapsulated in a second 802.1Q tag from a
service-provider network (called an SP-VLAN ID). The switch supports
rewriting the VLAN tag of egress traffic when the ingress traffic is
tagged.
The switch also supports Layer 2 Protocol Tunneling for STP, CDP, VTP,
PVST+, with Cisco-proprietary multicast address (01-00-0c-cd-cd-d0)
replacement.
