Both the MAC address and the mask must be introduced as a sequence of 6 bytes
separated by
colons,
hh:kk:xx:yy:ww:zz
, by using hexadecimal notation.
When the router must decide if a given MAC address is accessible, the mask is “
anded
”; if the result
is a configured MAC address, then it is accessible. In order to specify a single MAC address, the
mask must be set to
ff:ff:ff:ff:ff:ff
or it must be not specified, since this is the preset value.
In order to specify that the MAC address or the family of the configured ones are the only
accessible from the peer, the command is:
set dlsw icanreach mac-exclusive
In order to remove the exclusivity option the following command is used:
set dlsw icanreach no-mac-exclusive
In order to remove a MAC address from the list, the following command is used:
set dlsw icanreach no-mac-addr <mac address> [ mask <value> ]
It is also possible to define a list SAPs accessible from the local peer by using the command:
set dlsw icanreach saps <value> [ <value> ]
The SAPs must be specified in hexadecimal notation and must be separated by a space.
All the information about accessibility is sent by the local DLSw to the remote partner during the
exchange of capabilities. In this way the remote partner can avoid the transmission of explorative
messages (Can-u-reach-ex) with the consequent reduction of traffic.
In order to enable log function of DLSw, the following command is used:
set dlsw log on
In order to define a log level, the following command is used:
set dlsw log level <value>
In order to disable the log the command is:
set dlsw log off
In order to activate the DLSw the command is:
set dlsw on
In order to disable it the following command is used:
set dlsw off

SCENARIO
In a DLC scenario, it is necessary to establish on which Ethernet interface of Imola router the DLC
connection will be executed:
set dlc net-interface eth0|eth1
It is also necessary to configure the client MAC address in the following way:
set dlc source-mac <mac address>
In this case too, the MAC address must be introduced as a sequence of 6 bytes separated by colons,
hh:kk:xx:yy:ww:zz
, by using hexadecimal notation.
