240 Gigabit optical port +2 40G optical port switches
Advantages
1. Excellent performance
With 760G backplane bandwidth.
Packet forwarding rate reached 565.44Mpps.
Ethernet/IEEE802.3 packet size (64 bytes to 1522 bytes)
Jumbo packets are 9216 bytes at most.
2. Safe and reliable
Provide DOS, distributed denial of service, deception and virus
defense.
Support IEEE802.1x, provide port-based user authentication,
security control technology and policy control list.
Limit the maximum number of hosts connected to the port, and
multiplex the Ethernet interface to increase the bandwidth and
system redundancy.
Policy control list, traffic regulation
3. Easy to use and maintain
It can be managed in many ways, such as Web and SNMP.
XModem protocol is supported, and software upgrade and BootRom
upgrade can be carried out through TFTP/ZMODEM.
4. Strong traffic and broadcast management
Automatically detect and suppress broadcast storms, support the
detection of IGMP messages, and effectively limit the flooding of
broadcast messages.
Flow control supporting full-duplex mode and half-duplex mode
Support the rate limitation of Ethernet interface in 1M steps.
Overview
240 Gigabit optical port +2 40G optical port switches are a switch
that provides 20 10G SFP+ interfaces, 4 25G SFP28 interfaces and 2
40G QSFP interfaces. It provides high-capacity switching
capability, perfect security control strategy and CPU protect
policy to improve fault tolerance, ensure the stable operation of
the network and the load balance of links. The equipment supports
automatic DoS attack prevention and SNMP, IEEE 802.1, spanning tree
and rapid spanning tree protocol, and link aggregation.
