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 or
HTTPS. (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 and runs on the Management VLAN. The Bonjour console automatically detects the device and
displays it.

Bonjour in Layer 2 System Mode

Bonjour Discovery can only be enabled globally, and not on a per-port or per-VLAN basis. The device
advertises the services enabled by the administrator.
When Bonjour Discovery and IGMP are both enabled, the IP Multicast address of Bonjour appears on the
Adding IP Multicast Group Addresses page.
When Bonjour Discovery is disabled, the device stops service type advertisements and does not respond
to requests for service from network management applications.
By default, Bonjour is enabled on all interfaces that are members of the Management VLAN.
