Description
●
Web browser upgrade (HTTP/HTTPS) and TFTP
●
Upgrade can be initiated through console port as well
●
Dual images for resilient firmware upgrades
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. A single session is supported.
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. A single session is supported.
DHCP Options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-
configuration (with configuration file download), and DHCP relay,
Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass
deployment
Simplified configuration of QoS and security capabilities
Securely transfer files to and from the switch
Scriptable command-line interface
Support for Small Business Toolbar application
Localization of GUI and documentation into multiple languages
Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade; DHCP
client; BOOTP; SNTP; Xmodem upgrade; cable diagnostics; ping; syslog; Telnet client (SSH secure support)
Automatically turns off power off on Gigabit Ethernet RJ-45 port when detecting link down
Active mode is resumed without loss of any packets when the switch detects the link up
Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter
than 10m.
Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces
Up to 8000 MAC addresses
The switch advertises itself using the Bonjour protocol.
LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices
that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP
phones.
The switch advertises itself using the Cisco Discovery Protocol.
Maximum power of 15.4W to any 10/100 or Gigabit Ethernet base port. The total power available for PoE per
switch is as follows:
