ACL Configuration" page can result in you being unable to access the device. You should
therefore configure an access rule that allows access to the management
before you enable
the function.

switch.
As default, the function is disabled.
The access rules are managed on the "Management ACL Configuration" page, see section
Management Access Control List (Page 127)

If the function is disabled, there is unrestricted access to the management of the IE switch.
T

network.
Supported version: NTP V3
PTP
Note
This option is available only with switches capable of PTP.

by the master. To achieve this, the IE switch must be operated as a "Transparent Clock" in a
PTP network.
