STP Bridge Protocol Data Unit |
|
|
A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port |
|
|
STP Root Guard |
|
|
Prevents a port from being selected as a root port, effectively preventing bridges in the LAN segment connected to the port from being a root bridge |
|
|
DHCP Snooping |
|
|
Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server |
|
|
IP Source Guard (IPSG) |
|
|
When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing |
|
|
Dynamic ARP Inspection (DAI) |
|
|
The switch discards ARP packets from a port if there is no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks |
|
|
IP/Mac/Port Binding (IPMB) |
|
|
The features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) above work together to prevent DOS attacks in the network, thereby increasing network availability |
|

Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received |
|
|
Secure Sensitive Data (SSD) |
|
|
A mechanism to manage sensitive data (such as passwords, keys, etc) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user configured access level and the access method of the user |
|
|
Layer 2 Isolation Private VLAN Edge (PVE) with Community VLAN |
