802.1Q VLAN ID
The configuration at the switch must be observed for
setting the VLAN ID. An empty 802.1q VLAN ID field (16
bit) assumes the value 0. The VLAN ID with the value 0
switches QoS (Quality of Service) off according to 802.1q
ab. If the switch at the port to the device happens to be
configured to a different VLAN ID, the same value must be
specified here to allow a prioritisation from the Ethernet. To
be able to distinguish between the VLANs, the Ethernet
packet is extended by 4 bytes, of which 12 bits are
intended for the inclusion of the VLAN ID, making 4094
VLANs possible (VLAN ID 0 and 4095 are reserved or
invalid).
802.1p VLAN Priority
In the 802.1p VLAN Priority field (3 bit), the associated
VLAN priority level (a value between 0 and 7) can be
specified, in order that voice data is given priority
forwarding, for example.
Note
A device cannot work as a NTP Server. Information transmitted to other devices via
DHCP, in these devices cannot be overwritten by a local configuration.
4.5.2.5
Submenu DHCP Leases
VoIP devices that have used this interface to fetch an IP address of the embedded
DHCP server, are displayed here.
•
Clicking once on the Type dynamic of a displayed lease enables you to change
the dynamic lease into a reserved lease and at the same time to define a host
name or release the lease.
•
Clicking once on the Type reserved of a displayed lease enables you to release
the reserved lease.
In addition, in chapter Reserve IP Address, you have the possibility to assign a
certain IP address to a certain MAC address. In the Cleanup chapter assigned DHCP
leases can be deleted again.
•
Clicking once on Clear dynamic leases deletes all dynamically assigned leases.
