Huawei ekitEngine S220 Series Switches Datasheet

Flexible Ethernet Networking
⚫ In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning
Tree Protocol (MSTP), eKitEngine S220 series switches support the latest Ethernet Ring Protection Switching (ERPS)
standard in the industry. ERPS is defined in ITU-T G.8032. It provides millisecond-level protection switching based on
traditional Ethernet MAC and bridging functions.
Diversified Security Control
⚫ eKitEngine S220 series switches support multiple security authentication modes including MAC address authentication
and 802.1X authentication, and dynamically deliver user policies (VLAN, QoS, and ACL). eKitEngine S220 series switches
support port-based 802.1X authentication, MAC address authentication, and multi-mode authentication.
⚫ eKitEngine S220 series switches provide a series of mechanisms to defend against DoS attacks and user-targeted
attacks. DoS attacks are targeted at switches and include SYN flood, Land, Smurf, and ICMP flood attacks. User-targeted
attacks include bogus DHCP server attacks, IP/MAC spoofing attacks, DHCP request flood attacks, and attacks with variable
DHCP CHADDR values in packets.
⚫ eKitEngine S220 series switches can generate and maintain DHCP snooping binding entries and discard invalid packets
that do not match the binding entries. DHCP snooping trusted and untrusted ports can be specified to ensure that users
connect only to the authorized DHCP server.
Easy Operations and Maintenance
⚫ eKitEngine S220 series switches can be managed and maintained using SNMPv1, SNMPv2c, SNMPv3, CLI, web system,
or SSHv2.0.
PoE Power Supply
PoE models of eKitEngine S220 series switches provide the following capabilities:
⚫ Fast PoE: PoE switches can supply power to PDs within seconds upon power-on, which is different from common
switches that supply power to PDs in 1 to 3 minutes after power modules are installed. When a PoE switch restarts due to a
power failure, it continues to supply power to PDs immediately after being powered on without waiting until it completes
the restart. This greatly shortens the power-off time of PDs.
⚫ Perpetual PoE: When a PoE switch restarts (for example, during software upgrade), it continues to supply power to
downstream PDs, ensuring uninterrupted PoE power supply.
Smart Upgrade
⚫ Based on Huawei Online Upgrade Platform (HOUP), eKitEngine S220 series switches support smart upgrade. They
obtain the version upgrade path from the HOUP and download the new system software. The upgrade process is highly
automated as it supports one-click upgrade. In addition, this feature supports system software pre-loading, which greatly
shortens the upgrade time and reduces the service interruption time.
⚫ Smart upgrade greatly simplifies device upgrade operations, making it possible for customers to upgrade versions by
themselves. This feature helps customers reduce considerable maintenance costs. In addition, the upgrade policy of the
HOUP is used to standardize the upgrade path, which greatly reduces the risk of upgrade failure.
