Based on the new-generation high- performance hardware and AB platform, it supports functions such as ACL, Qin and QoS. Its simple management mode and flexible installation can meet the requirement of any complicated scenarios.
Alpha Bridge Series has Various Models .Here we have given Specification of AS228P Switch.
Product Characteristics
Carrier-Level Ethernet Access Switch
- AS228P Series 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.
- AS228P Series has powerful ACL functions to access and control L2-L7 data based on physical port, providing carriers flexible and various policy control methods.
- AS228P Series supports In-Service Software Upgrade (ISSU) to ensure the unremitting data forwarding during system upgrade.
- AS228P Series supports various L2 multicast functions such as IGMP-snooping, fast-leave and MVR to fully meet the operation requirements of carrier’s IPTV.
AS228P Series supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6 and Path MTU discovery.
AS228P Series supports Ping, Traceroute, Telnet, SSH and ACL based on IPv6, meeting IPv6 networks’ equipment management requirements and service control requirements.
AS228P Series supports priority retagging and complicated now classification based on VLAN, MAC, source address, destination address, IP or priority, better streamlining carrier’s services.
AS228P Series provides flexible bandwidth control policies, supporting port-/ow-based ow limit, ensuring the line speed forwarding of each port.
AS228P Series supports multiple queue schedule algorithms such as SP, WRR and “SP + 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 Open source Tacacs.
- AS228P Series supports storm/multicast/unicast limit, ensuring the normal running of equipment in harsh network conditions.
- AS228P Series supports perfect ring detection mechanism, ensuring the long-term stable running of network.
- AS228P Series supports port isolation within the same VLAN, DHCP-Snooping, and IP + MAC + Port binding.
- AS228P Series supports many management modes such as the CLI, Telnet, SSH, SSL and SNMP.
- AS228P Series supports the WEB management mode, which is easy and efficient for installing and debugging the device.
- AS228P Series supports FTP, TFTP and SFTP.
- AS228P Series supports ISSU (In-Service Software Upgrade). AS228P Series supports SNMP and 3rd Party
- 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.
- AS228P Series supports Zero Touch Provisioning (ZTP) function to minimize manual operator intervention and helps reduce customers’ initial deployment costs.
