    Firmware upgrade: • Web browser upgrade (HTTP/HTTPS) and TFTP and SCP, Upgrade can be initiated through console port as well, Dual images for resilient firmware upgrades
    Port mirroring:Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port.
    VLAN mirroring:Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 8 source VLANs can be mirrored to one destination port.
    DHCP (Options 12, 66, 67, 82, 129, and 150):DHCP options facilitate tighter control from a central point (DHCP Server), to obtain IP address, auto configuration (with configuration file download), DHCP Relay, and host name.
    Autoconfiguration with Secure Copy (SCP) file download :Enables secure mass deployment with protection of sensitive data.
    Text-editable configs :Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment.
    Smartports : Simplified configuration of QoS and security capabilities.
    Secure Copy (SCP) :Securely transfer files to and from the switch.
    Textview CLI :Scriptable CLI. A full CLI as well as a menu CLI is supported.
    Cloud Services Support for Cisco Small Business and Cisco OnPlus.
    Localization :Localization of GUI and documentation into multiple languages.
    Login banner :Configurable login banners for web as well as CLI.
    Time-based port operation :Link up or down based on user-defined schedule (when the port is administratively up).
    Other management:Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade; DHCP client; BOOTP; Simple Network Time Protocol (SNTP); Xmodem upgrade; cable diagnostics; Ping; syslog; Telnet client(SSH secure support)
    Automatic time settings from Management Station.

    SSH : SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.
    SSL : Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch.
    IEEE 802.1X (Authenticator role): RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode and single/multiple sessions
    Supports time-based 802.1X
    Dynamic VLAN assignment
    STP BPDU Guard: A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops.
    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):This prevents IP Address Spoofing.
    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
    Secure Core Technology (SCT):Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received.
    Secure Sensitive Data (SSD)
    Layer 2 isolation (PVE) with community VLAN*:Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic; supports multiple uplinks.
    Port security : Ability to lock MAC addresses to ports, and limit the number of learned MAC addresses.
    RADIUS/TACACS+ : Supports RADIUS and TACACS authentication. Switch functions as a client.
    RADIUS accounting
    Storm control :Broadcast, multicast, and unknown unicast.
    DoS prevention : DoS attack prevention.
    Congestion avoidance A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization.
    Multiple user privilege levels in CLI Levels 1, 7, and 15 privilege levels.
    ACLs : Support for up to 2000 rules on 500 Series and 3000 on 500X series.
    Time-based ACLs supported.
