|
VLAN |
Support for up to 4096 VLANs simultaneously |
|
Voice VLAN |
Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS |
|
Multicast TV VLAN |
Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (also known as MVR) |
|
Q-in-Q VLAN |
VLANs transparently cross a service provider network while isolating traffic among customers |
|
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) |
Protocols for automatically propagating and configuring VLANs in a bridged domain |
|
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 blackholing of traffic in switched networks |
|
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2 |
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 1K multicast groups (source-specific multicasting is also supported) |
|
IGMP Querier |
IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router |
|
Head-Of-Line (HOL) blocking |
HOL blocking prevention |
|
Loopback Detection |
Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP |
|
Jumbo frames |
Up to 9K (9216) bytes |
|
Layer 3 |
|
|
IPv4 routing |
Wirespeed routing of IPv4 packets |
|

Wirespeed routing of IPv6 packets |
|
Classless Interdomain Routing (CIDR) |
Support for CIDR |
|
Layer 3 Interface |
Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface |
|
DHCP relay at Layer 3 |
Relay of DHCP traffic across IP domains |
|
User Datagram Protocol (UDP) relay |
Relay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP packets |
|
DHCP Server |
Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes |
|
Security |
|
|
Secure Shell (SSH) Protocol |
SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported |
|
Secure Sockets Layer (SSL) |
SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch |
|
IEEE 802.1X (Authenticator role) |
802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions |
|
Web-based authentication |
Web based authentication provides network admission control through web browser to any host devices and operating systems |
|
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 |
|
STP Root Guard |
This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes |
|
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. 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 |
PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks |
|
Port security |
The ability to lock source MAC addresses to ports and limits the number of learned MAC addresses |
|
RADIUS/TACACS+ |
Supports RADIUS and TACACS authentication. Switch functions as a client |
|
Storm control |
Broadcast, multicast, and unknown unicast |
|
RADIUS accounting |
The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session |
|
DoS prevention |
Denial-Of-Service (DOS) attack prevention |
|
ACLs |
Support for up to 512 rules |
|
Quality of Service |
|
|
Priority levels |
8 hardware queues |
|
Scheduling |
Strict priority and Weighted Round-Robin (WRR)Queue assignment based on DSCP and class of service (802.1p/CoS) |
|
Class of service |
Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/Type of Service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and remarking ACLs, trusted QoS |
|
Rate limiting |
Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based |
|
Power over Ethernet (PoE) |
|
|
802.3af PoE, 802.3at PoE+, and 60W PoE power are delivered over any of the RJ-45 ports within the listed power budgets |
Switches support 802.3at PoE+, 802.3af, 60W PoE, and Cisco prestandard (older) PoE. Maximum power of 60W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached. The total power available for PoE per switch is as follows: |
|
PoE powered device and PoE passthrough |
In addition to AC power, compact switch models can work as PoE powered devices and be powered by PoE switches connected to the uplink ports. The switch can also pass through the power to downstream PoE end devices if required |
