IPv6 address rules for NetBackup clients
The IPv6 address ranges can specify individual clients or entire subnets.
An IPv6 address can take the following forms:
a.b.c.d.
Where a, b, c, and d are hexadecimal integers in the range 0-ffff.
a
A 32-bit integer that represents the full IP address in network byte order. (The big endian, the most significant byte is first on the wire.)
Enter IPv6 addresses as hexadecimal numbers.
Neither the subnet nor the host part of an IPv6 address can be zero.
Only ordinary IPv6 addresses are accepted.
Do not create multiple entries that specify the same range of IPv6 addresses. If multiple entries are created, NetBackup uses the last one found.
In the following example, NetBackup uses the second entry:
LIMIT_BANDWIDTH = 2001:db8:1:110::/48 500 LIMIT_BANDWIDTH = 2001:db8:1:110::/48 200
This rule also applies to multiple entries that specify an exact client address, as follows:
LIMIT_BANDWIDTH = 2001:db8:1:110:0:0:0:8b72::/128 200 LIMIT_BANDWIDTH = 2001:db8:1:110:0:0:0:8b72::/128 100
Do not specify IPv6 address ranges that overlap one another.
Consider the following:
LIMIT_BANDWIDTH = 2001:db8:1:110::/48 500 LIMIT_BANDWIDTH = 2001:db8:1:110::/48 500
The ranges overlap, and bandwidth limiting results are unpredictable.
Specify a range of addresses in one entry and an address for a specific client in other entries.
If a client is covered by an entry that specifies its exact IPv6 address and by another entry that specifies a range of IPv6 addresses, NetBackup uses the bandwidth value in the entry with the exact IP address.
The following sets the bandwidth for a range of IPv6 addresses:
LIMIT_BANDWIDTH = 2001:db8:1:110::/48 500
The following sets the bandwidth for a specific address that is within the range:
LIMIT_BANDWIDTH = 2001:db8:1:110:0:0:0:8b72::/128 200
In this case, NetBackup uses the specific entry (bandwidth of 200) for the client whose address is 2001:db8:1:110:0:0:0:8b72. This capability can also be used to exclude specific clients from bandwidth limiting. The order of the range and specific address entries in the bp.conf file is not significant.
