used on the assigned port only with the port security configuration function. For
example, assigning “00-00-e2-11-22-33” to Port 5 will always keep this Mac ID alive on
Port 5 but also limit this Mac address could work on Port 5 only.
Note: About Static Mac Address Filter-in (port binding) function
There is a Mac Security function for port security. If Mac Table Learning is set to
“Secure”, only these static Mac addresses can access network through the assigned
port. The other Mac addresses will be forbidden for network access through that port.
This function can be used for port binding security application. Please refer to Section
6.3 for the details of the Mac address filter-in operation of the switch.
7. Dynamic Mac ID Number Limit
Beside Static Mac ID Limit, there is another Dynamic Mac ID Number Limit function for
Mac address security on port. This function can limit the Mac ID number to access
network through a port. For example, five Mac ID are allowed for Port 2. That means
up to five users are allowed, but don’t care who the users are. It is done by “Limit
Control” function in “Security - Network” function.
8. IEEE 802.1x Port Security Function
If the 802.1x function is enabled, the switch will act as an authenticator for users
accessing network through the switch. It will need a RADIUS server for the
authentication function. Users will be asked for username and password before network
access. If the RADIUS server authenticates it, the switch will enable the port for
network access. This function is very useful for network security application to prevent
illegal users access network through the switch.
9. Rate Control
This function can limit the traffic rate for physical ports. The traffic could be ingress
traffic or egress traffic. This function can limit the network bandwidth utilization of
users.
10. IP Multicast with IGMP Snooping
IP multicast function can forward packets to a group of users connected on different
ports. The user group is learned by the switch from packets of IGMP active router with
IGMP snooping function. It is often used for video applications
11. MVR (Multicast VLAN Registration)
VLAN function will isolate traffic between VLAN groups. But it will also isolate IP
multicast traffic for subscribers in different VLANs. The MVR function allows one
multicast VLAN to be shared by subscribers in different VLANs. That can reduce the
multicast traffic for VLANs.
12. IP Source Guard
This function can limit the IP address for accessing network from switch port. That can
prevent illegal IP problem in network.
13. ACL (Access Control List)
This function is used to define network access control policy - a list of packet filtering
rules. The filtering conditions are Layer2 ~ Layer4 - including Mac address, VLAN ID,
Ethernet Type, IP address, ARP Packets, ... If conditions are matched, the traffic could
be discarded, forwarded, logging or rate limit.
14. LLDP (Link Layer Discover Protocol)
LLDP protocol is used by network devices to advertise their identity, capabilities, and
interconnections on a LAN network. This switch can advertise its system information,
and show the information of the connected network devices by LLDP protocol.
15. Software Backup/Update
This switch supports backup and update functions for its internal software and its
network configuration. It could be done in two ways.
a. From web browser : doing by http protocol and by web browser for run-time code
and configuration backup/update.
b. From telnet or console command : doing by tftp protocol for run-time code and
configuration backup/update.
