NOTE
Cisco Small Business SG200 Series 8-port Smart Switch
• Cisco-specific device description (csco-sb)—This service enables clients
to discover Cisco switches and other products deployed in small business
networks.
• Management user interfaces—This service identifies the management
interface available on the switch (HTTP).
When a Bonjour-enabled switch is attached to a network, any Bonjour client can
discover and get access to the management interface without prior configuration.
A system administrator can use an installed Internet Explorer plug-in to discover
the switch. The web-based switch configuration utility shows up as a tab in the
browser.
When Bonjour Discovery and IGMP are both enabled, the IP Multicast address of
Bonjour is displayed on the IP Multicast Group Address Page. When Bonjour
Discovery is disabled, the switch stops service type advertisements and does not
respond. Bonjour works in both IPv4 and IPv6 networks.
To enable the switch to be discovered through Bonjour:
Click Administration > Discovery - Bonjour in the navigation window.
Select Enable.
Click Apply.
The IEEE 802. 1 AB standard, Link Layer Discovery Protocol (LLDP), describes a
method by which stations residing on a LAN advertise identification information,
capabilities, and physical descriptions. The information is exchanged in LLDP data
units (LLDPDUs) which comprise type-length-value (TLV) structures. Various TLVs
might be included in LLDPDUs, depending on the information that the
administrator configures the port to advertise.
Information learned through LLDPDUs is stored in MIBs, and the information might
be accessible by a network management system (NMS) such as SNMP. This
framework is extensible and allows advanced utilization in areas such as VoIP
networks.
LLDPDUs only communicate information; they do not automatically configure the
switch.
