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 ECS4120 Series 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, Authorization and Accounting) via RADIUS,
TACACS+, enables centralized control of the switch. You can also
authorize access rights per user and account for all actions
performed by administrators.
Service Monitoring and Management
The ECS4120-28Fv2-AF 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 and delay variation for verifying SLA conformance
(for billing purposes) and providing advance indication of
performance degradation before a service outage occurs.
Virtual Private Networks
The ECS4120-28Fv2-AF 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.
Comprehensive QoS
The ECS4120-28Fv2-AF 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.
The ECS4120-28Fv2-AF 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 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.
Multicast VLANs are shared in the network, while subscribers
remain in separate VLANs. This increases network security and
saves bandwidth on core links. Multicast streams do not have to be
routed in core L3 switches, which saves CPU power.
Multicast VLAN Registration (MVR) is designed for applications
such as Media-on-Demand that send multicast traffic across an
Ethernet network.
IPv6 Support
The switch supports a number of IPv6 features, including IPv6
Management, DHCPv6 Snooping with Option 37, IPv6 Source
Guide, and MVR6.
