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 ECS5520-18X/ECS5520-18T 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 switches. Access rights
can be authorized per user and account for all actions performed by
administrators.
Virtual Private Networks
The ECS5520-18X/ECS5520-18T 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 ECS5520-18X/ECS5520-18T 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 ECS5520-18X/ECS5520-18T 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 VLAN Registration (MVR) is designed for applications such
as Media-on-Demand that send multicast traffic across an Ethernet
network.
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.
IPv6 Support
The switch supports a number of IPv6 features, including IPv6
Management, DCHPv6 Snooping with Option 37, IPv6 Source Guide.
