AS2400 Series L2 Switch

ACT AS2400 series Optical Fiber 10GE Switch is an economical series of high-performance L2 switches which provide network operators and service providers with a cost-effective access layer for Fast Ethernet P2P services in Fiber to The Home/Business (FTTH & FTTB) networks.

• Industrial Ethernet ring with zero delay and zero packet loss

• Supports industry-level EAPS

• Supports telecom-level Ethernet ring protection protocol

• <50 ms protection shift time

• Supports In-Service Software Upgrade (ISSU)

• Supports various L2 multicast functions, including IGMP-snooping, fast-leave, and trans-VLAN multicast copy

• Supports management modes such as console port, Telnet, SSH, etc.

• Supports SNMP and WEB management mode

• Supports priority retagging and complicated flow classification based on VLAN, MAC, source address, destination address, IP, or priority to better streamline carrier services

• Supports 8 priority queues per port

• Supports IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6, path MTU discovery, etc.

• Equipment-level security

• Supports IEEE802.1x, Radius, and TACACS+ security authentication

• Supports storm/multicast/unicast limit
