Product Overview
- 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.
