Datasheet L2 Switch
Stacking
ECS4120-28Fv2-I_EUS (Only Hardware Version R01A) supports
hardware stacking via 10G SFP+ port with Edgecore DAC cable
(ET5402-DAC-1M) , no special stacking module and stacking cable are
needed, up to 4 switches can be stacked together. The switch stack
can be managed with a single IP address as a single entity, one switch
will become master and all other switches within the stack will
become slave, the configuration and firmware can be automatically
synchronized from master to slave for easy management. When 4
switches are stacked in a ring topology, if there is link failure on the
stacking cable, traffic will go through the redundant link so there is no
network downtime. The hardware stacking supports cross stack
trunking, for example, 10G ports on different switches can be trunked
together, if one unit fail, there is still redundant port on the switch for
uplink.
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 Series 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 Series 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.
Private VLANs (traffic segmentation per port) isolate edge ports to
ensure user privacy.
DAI (Dynamic ARP Inspection) is a security feature that validates
Address Resolution Protocol (ARP) packets in a network. DAI allows a
network administrator to intercept, log, and discard ARP packets with
invalid MAC-to-IP address bindings.
Secure Shell (SSH) and Secure Sockets Layer (SSL/HTTPS) encrypt
Telnet and web access to the switch, providing secure network
management.
The ECS4120 Series also supports both RADIUS and TACACS+
authentication methods to secure your network.
Comprehensive QoS
The ECS4120 Series 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 Series 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.
