Product Characteristics
Carrier-Level Ethernet Access Switch
- Alpha Bridge AS200/28/T 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/T 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/T supports In-Service Software Upgrade (ISSU) to ensure the unremitting data forwarding during system upgrade.
- Alpha Bridge AS200/28/T supports various L2 multicast functions such as IGMP-snooping, fast-leave and MVR to fully meet the operation requirements of carrier’s IPTV.
Comprehensive IPv6 Solutions
Enhanced QoS
Security+
Easy Management and Maintenance
Comprehensive IPv6 Solutions
- Alpha Bridge AS200/28/T supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6 and Path MTU discovery.
- Alpha Bridge AS200/28/T supports Ping, Traceroute, Telnet, SSH and ACL on the basis of IPv6, meeting IPv6 network’s equipment management requirements and service control requirements.
Enhanced QoS
- Alpha Bridge AS200/28T 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 AS200/28T provides flexible bandwidth control policies, supporting port-/flow-based flow limit, ensuring the line speed forwarding of each port.
- Alpha Bridge AS200/28T 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/T supports storm/multicast/unicast limit, ensuring the normal running of equipment in harsh network conditions.
- Alpha Bridge AS200/28/T supports perfect ring detection mechanism, ensuring the long-term stable running of network.
- Alpha Bridge AS200/28/T supports port isolation within the same VLAN, DHCP-Snooping, and IP + MAC + Port binding.
Easy Management and Maintenance
- Alpha Bridge AS200/28/T supports many management modes such as the CLI, Telnet, SSH, SSL and SNMP.
- Alpha Bridge AS200/28/T supports the WEB management mode, which is easy and efficient for installing and debugging the device.
- Alpha Bridge AS200/28/T supports FTP, TFTP and SFTP.
- Alpha Bridge AS200/28/T supports ISSU (In-Service Software Upgrade).
- Alpha Bridge AS200/28/T supports SNMP and NMS smart network management platform. The combination realizes automatic equipment discovery, Network Topology Management, equipment configuration management, performance data statistics and analysis and trouble management.
- Alpha Bridge AS200/28/T supports Zero Touch Provisioning(ZTP) function to minimize manual operator intervention and helps reduce customer’s initial deployment costs.
