 DS-3E2528P supports the telecom-level Ethernet-ring protection protocol with a protection shift time of less
than 50ms, STP/RSTP, backup of active and standby uplinks, and LACP link aggregation to cater to the
requirements of high reliability of carriers;
 DS-3E2528P has powerful ACL functions to access and control L2-L7 data, providing carriers flexible and various
policy control methods;
 DS-3E2528P supports In-Service Software Upgrade (ISSU) to ensure the unremitting data forwarding during
system upgrade;
 DS-3E2528P supports various L2 multicast functions such as IGMP-snooping, user fast-leave mechanism and
trans-vlan multicast copy;
 DS-3E2528P supports IEEE 802.3AF/AT standard, built-in large power supply, no need of external power supply,
that is, 24-port AF full-load power supply.
 DS-3E2528P supports the configuration of Base-T port priority when the power is inadequate.
 DS-3E2528P supports POE port and up to 4KV power thunder-proof.
 DS-3E2528P supports priority retagging and complicated flow classification based on VLAN, MAC, source
address, destination address, IP or priority to better streamline carrier’s services;
 DS-3E2528P provides flexible bandwidth control policies, supporting port-/flow-based flow limit, and ensuring
the line speed forwarding of each port to make sure the high quality of network services;
 DS-3E2528P supports multiple queue schedule algorithms such as SP, WRR, or “SP plus WRR”;
 Equipment-level security: The advanced hardware infrastructure design realizes the level-based packet
schedule and packet protection, prevents DoS-/TCP-related SYN Flood, UDP Flood, Broadcast Storm or large
traffic attacks, and supports level-based command line protection, endowing different levels of users with
different management permissions;
 Perfect security authentication mechanisms: IEEE 802.1x, Radius and BDTacacs+;
 DS-3E2528P supports storm/multicast/unicast limit which ensures the normal running of equipment in harsh
network conditions;
 DS-3E2528P supports perfect ring detection mechanism which ensures the long-term stable running of
network;
 DS-3E2528P supports port isolation within the same VLAN, DHCP-Snooping, and IP plus MAC plus Port binding
for ensuring user data security;
 DS-3E2528P supports many management modes such as the console port, Telnet, SSH;
 DS-3E2528P supports the WEB management mode, which is easy and efficient so that it makes installation and
debugging convenient;
 DS-3E2528P supports TFTP-patterned file upload/download management;
