|
Security |
|
Secure Shell (SSH) Protocol |
SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported |
|

Dynamic VLAN assignment |
|
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 |
|
Support |
IP Source Guard (IPSG), IP/MAC/Port Binding (IPMB), Secure Core Technology (SCT), Secure Sensitive Data (SSD), Layer 2 isolation Private VLAN Edge (PVE) with community VLAN |
|

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 |
|

|
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:
Power Dedicated to PoE: 185W
Number of Ports That Support PoE: 24 |
|
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
Maximum of 60W can be drawn per uplink port if the peer PoE switch supports 60W PoE. When multiple uplink ports are connected to PoE switches, the power drawn from these ports is combined
When AC power is connected and functioning properly, it will have priority over the PoE powered device function. The PoE powered device function will then act as a backup power source to the AC power. The PoE powered device function will be the primary power source for the switch if AC power is not connected |
