ALPHA BRIDGE LAYER 2 Switches (AS200/28/P)
Product Overview
Alpha Bridge AS200/28/P is a new-generation intelligent gigabit access switch designed for carrier’s IP MAN and enterprise networks. Based on the new-generation high performance hardware and our OS platform, it supports functions such as ACL, Q-in-Q and QoS. Its simple management mode and flexible installation can meet the requirement of any complicated scenarios.
Product Characteristics
Carrier-Level Ethernet Access Switch
- Alpha Bridge AS200/28/P supports the carrier-level Ethernet ring protection protocol with less than 50ms recovery time, STP/RSTP/MSTP, backup uplink ports, and LACP link aggregation to cater to the requirements of high reliability of carriers.
- Alpha Bridge AS200/28/P has powerful ACL functions to access and control L2-L7 data based on physical port, providing carriers flexible and various policy control methods.
- Alpha Bridge AS200/28/P supports In-Service Software Upgrade (ISSU) to ensure the unremitting data forwarding during system upgrade.
- Alpha Bridge AS200/28/P supports various L2 multicast functions such as IGMP-snooping, fast-leave and MVR to fully meet the operation requirements of carrier’s IPTV.
Enhanced QoS

Easy Management and Maintenance
Intelligent PoE+
Enhanced QoS
- Alpha Bridge AS200/28/P supports priority retagging and complicated flow classification based on VLAN, MAC, source address, destination address, IP or priority, better streamlining carrier’s services.
- Alpha Bridge AS200/28/P provides flexible bandwidth control policies, supporting port-/flow-based flow limit, ensuring the line speed forwarding of each port.
- Alpha Bridge AS200/28/P supports multiple queue schedule algorithms such as SP, WRR and “SP + WRR”.
Security+
- 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 Tacacs+.
- Alpha Bridge AS200/28/P supports storm/multicast/unicast limit, ensuring the normal running of equipment in harsh network conditions.
- Alpha Bridge AS200/28/P supports perfect ring detection mechanism, ensuring the long-term stable running of network.
- Alpha Bridge AS200/28/P supports port isolation within the same VLAN, DHCP-Snooping and IP + MAC + Port binding.
Easy Management and Maintenance
- Alpha Bridge AS200/28/P supports many management modes such as the CLI, Telnet, SSH, SSL and SNMP.
- Alpha Bridge AS200/28/P supports the WEB management mode, which is easy and efficient for installing and debugging the device.
- Alpha Bridge AS200/28/P supports FTP, TFTP and SFTP.
- Alpha Bridge AS200/28/P supports ISSU (In-Service Software Upgrade).
- Alpha Bridge AS200/28/P supports SNMP. The combination realizes automatic equipment discovery, Network Topology Management, equipment configuration management, performance data statistics and analysis and trouble management.
Intelligent PoE+
- AS200/28/P support IEEE 802.3af/at PoE standard, and power mapping scales up to a maximum of 370W of PoE+ power.
- AS200/28/P support PoE non-stop power supply. The PoE+ power is maintained during a switch reload.
- AS200/28/P support manual and dynamic PoE power allocation.
- AS200/28/P support manual and dynamic PoE power allocation.
