Remote Monitoring
(RMON)
Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for
enhanced traffic management, monitoring, and analysis
IPv4 and IPv6 Dual Stack
Coexistence of both protocol stacks to ease migration
Port Mirroring
Traffic on a port or VLAN 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. Four sessions are supported.
Firmware Upgrade
●
Web browser upgrade (HTTP/HTTPS) and Trivial File Transfer Protocol (TFTP)
●
Dual images for resilient firmware upgrades
DHCP (Option 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 hostname
Time Synchronization
Simple Network Time Protocol (SNTP)
Login Banner
Configurable multiple banners for web as well as CLI
Other Management
HTTP/HTTPS; TFTP upgrade; DHCP client; BOOTP; cable diagnostics; ping; traceroute; syslog
Discovery
Bonjour
The switch advertises itself using the Bonjour protocol
Link Layer Discovery
Protocol (LLDP) (802.1ab)
with LLDP-MED
Extensions
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.
Cisco Discovery
Protocol
The switch advertises itself using the Cisco Discovery Protocol. Display brief information for connected
Cisco network devices, IP phones, and wireless access points
Minimum Requirements
Web Configuration
Browser: Internet Explorer 8 or later; Mozilla Firefox 20 or later; Google Chrome 23 or later; Safari 5.1 or
later
Power Efficiency
EEE Compliance
(802.3az)
Support 802.3az Energy Efficient Ethernet on all ports; substantially reduce the power consumption when
link bandwidth is not at full utilization
Energy Detect
Automatically turns power off on Gigabit Ethernet and 10/100 RJ-45 ports when detecting a link down
Active mode is resumed without loss of any packets when the switch detects the link up
Power Over Ethernet
802.3af PoE or 802.3at
PoE+ Delivered over Any
of the RJ-45 Ports Within
the Listed Power
Budgets
Switches support 802.3af, 802.3at, and Cisco pre-standard (legacy) PoE on port 1 to port 4 with
maximum power of 30 W per port; switches support 802.3af and Cisco pre-standard (legacy) PoE on
other RJ-45 ports with maximum power of 15.4 W per port
This applies to all PoE-enabled models; the maximum number of ports providing PoE power
simultaneously is determined by the total PoE budget for the switch, and the actual power requirement of
PD devices
The total power available for PoE per switch is as follows:
Model Name
Power Dedicated to PoE
Number of Ports That Support PoE
SF220-24P
180 W
24
SF220-48P
375 W
48
SG220-26P
180 W
24
SG220-50P
375 W

Pre-Standard PoE
Support Cisco Pre-Standard PoE
Intelligent PoE Power
Management
Support the granular power negotiation with CDP/LLDP communication with PD devices after IEEE
classification
