Entry in the IP ACL Meaning
192.168.0.123 the PC with IP Address "192.168.0.123" can access the device
192.168.0.1/24 all devices of subnet "192.168.0.1/24" can access the device
1234:4ef0:eec1:0::/64
all devices of subnet "1234:4ef0:eec1:0::/64" can access the
device
If you choose a wrong IP ACL setting and locked yourself out, please activate the
Bootloader Mode and use GBL_Conf.exe to deactivate the IP ACL. Alternatively, you
can reset the device to factory default.
4.4 IPv6
IPv6 Addresses
IPv6 addresses are 128 bit long and thus four times as long as IPv4 addresses. The first
64 bit form a so-called prefix, the last 64 bit designate a unique interface identifier. The
prefix is composed of a routing prefix and a subnet ID. An IPv6 network interface can be
reached under several IP addresses. Usually this is the case under a global address and
the link local address.
Address Notation
IPv6 addresses are noted in 8 hexadecimal blocks at 16 bit, while IPv4 normally is noted
in decimal. The seperator is a colon, not a period.
E.g.: 1234:4ef0:0:0:0019:32ff:fe00:0124
Leading zeros may be omitted within a block. The previous example can be rewritten as:
1234:4ef0:0:0:19:32ff:fe00:124
One may omit one or more successive blocks, if they consist of zeros. This may be
done only once within an IPv6 address!
1234:4ef0::19:32ff:fe00:124
One may use the usual decimal notation of IPv4 for the last 4 bytes:
1234:4ef0::19:32ff:254.0.1.36
4.5 Radius
The passwords for HTTP, telnet, and serial console (depending on the model) can be
stored locally and / or authenticated via RADIUS. The RADIUS configuration supports a
primary server and a backup server. If the primary server does respond, the RADIUS re-
