|
Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)
|
|
VLAN Translation
|
Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN
|
|

|
|

|
|
Unidirectional Link Detection (UDLD)
|
UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and black holing of traffic in switched networks

Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82
|
|
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping
|
IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 2K multicast groups (source-specific multicasting is also supported)
|
|

|
|
STP Bridge Protocol Data Unit (BPDU) Guard
|
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. This avoids accidental topology loops
|
|
STP Root Guard
|
This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
|
|
STP loopback guard
|
Provides additional protection against Layer 2 forwarding loops (STP loops)
|
|
DHCP snooping
|
Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers.
|
|
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 are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks.
|
|
IP/MAC/Port Binding (IPMB)
|
The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availability
|
|
Secure Core Technology (SCT)
|
Makes sure 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, and so on) securely on the switch, populating this data to other devices, and secure autoconfig.
