Security Controls
The following are user level security control:
IEEE 802.1x implements dynamic and port-based security provides the user ID authentication function and MAC/IP/VLAN/PORT combines at random, and prevent illegal user to accessing the network.
Segregating the ports is helpful to make sure that users can not monitor or access to other users on the same switch.
DHCP monitoring prevents spiteful users deceiving the server and sending spurious address, so it can start protecting IP source and create a binding table for the IP address of the user, MAC address, ports and VLAN to prevent user deceiving or use IP address of other users.
The following are the equipment level security control:
CPU security control technology can resist DoS attack from CPU.
SSH/SNMPv3 protocol supplies network management security.
Multilevel security of console can prevent unauthenticated users changing the switch configuration.
RADIUS authentication may carry on the common control to the switchboard.
The following are the network security control:
ACL based on port or Trunk makes it possible for users to apply security strategy to the ports of switches or Trunk.
Binding MAC address and the filtration based on source or destination supply effective control over the flux based on address.
Port MIRROR function is an effective tool for network management analyses.
QoS Guarantee
Applications of QoS are shown below:
Standard 802.1p QoS and DSCP field sort label and sort again based on single group with source and destination IP address, source and destination MAC address, and TCP/UDP port number.
Queue schedule arithmetic, Strict Priority(SP) & combination schedule.
Support CAR Committed Access Rate function. Manage the asynchronous upward and downward data stream from end
