Administration: Discovery
This section provides information for configuring Discovery.
It covers the following topics:
• Bonjour
• LLDP and CDP
• Configuring LLDP
• Configuring CDP
Bonjour
As a Bonjour client, the device periodically broadcasts Bonjour Discovery protocol
packets to directly-connected IP subnet(s), advertising its existence and the
services that it provides; for example, HTTP, HTTPs, and Telnet. (Use the Security
> TCP/UDP Services page to enable or disable the device services.) The device
can be discovered by a network management system or other third-party
applications. By default, Bonjour is enabled on the Management VLAN. The
Bonjour console automatically detects the device and displays it.
Bonjour in Layer 2 System Mode
When the device is in Layer 2 system mode, Bonjour Discovery is enabled
globally; it cannot be enabled on a per-port or per-VLAN basis. The device
advertises all of the services that have been turned on by the administrator based
on the configuration on the Services page.
When Bonjour Discovery and IGMP are both enabled, the IP Multicast address of
Bonjour appears on the Adding IP Multicast Group Address page.
