Tag 07 (T7 in the figure): VLAN identity 3 for the telephone, in ASCII text
format.
Note:
The VLAN identity for the telephone defined here in option 43
must not be equal to the VLAN identity for the PC defined in the
configuration file.
For more details about VLAN identity, see section 7.20 Virtual LAN
(VLAN) on page 51.
The different tags are optional, but if tag 02 is used tag 03 is mandatory.
The following applies for the ID string:
•
At new installation the string
Aastra IP-Phone
shall be entered in
DHCP option 43.
•
At upgrading (to application R7K or later and boot R3S or later) of
a site where the string
Ericsson IP-Phone
is used in DHCP option
43 and:
–
if vendor class (option 60) is used,
it is mandatory to initiate
the new vendor class for Aastra IP-Phone
.
–
if vendor class (option 60) is
not
used, the string
Ericsson
IP-Phone
can be kept in the DHCP server. The telephones
can handle both strings (but it is not allowed to have both
strings in the same option 43 structure).
The recommendation is to enter vendor classes in the DHCP server, one
vendor class for Aastra IP-Phone and another for Ericsson IP-Phone (in
case of new installation it is sufficient with only the first one). The vendor
specific information tags shall be equal within the two vendor classes.
