PLANET XGS3-24040 - Manual (Page 340)

25-53
Parameter:
<prefix-name> is a character string less than 32 characters, to use as IPv6 general prefix name.
<ipv6-prefix/prefix-length> is defined as IPv6 general prefix.
Command Mode:
Global Mode.
Default:
IPv6 general prefix is not configured by default.
Usage Guide:
If IPv6 general prefix is configured, the interface will use the configured prefix for IPv6 address
generating. Commonly, the general prefix is used for enterprise IPv6 prefix, and when entering an
IPv6 address, users can simply add the address suffix of to the name of the general prefix. The
configured address prefix will be reserved in the general address prefix pool. At most 8 general
prefix can be configured at the same time. When trying to remove a configured general prefix name,
the operation will fail if any interfaces used the configured prefix. Only one general prefix for a prefix
name. The general prefix can not use the same prefix definition with prefixes learnt from prefix
delegation.
Example:
To set the prefix of 2001:da8:221::/48 to general prefix my-prefix.
Switch(config)# ipv6 general-prefix my-prefix 2001:da8:221::/48
25.17 ipv6 local pool
Command:
ipv6 local pool <poolname> <prefix/prefix-length> <assigned-length>
no ipv6 local pool <poolname>
Function:
To configure the address pool for prefix delegation. The no form of this command will remove the
IPv6 prefix delegation configuration.
Parameters:
<poolname> is the name for the IPv6 address pool of the prefix delegation, the length name string
should be less than 32.
<prefix/prefix-length> is the address prefix and its length of the prefix delegation.
<assigned-length> is the length of the prefix in the address pool which can be retrieved by the
client, the assigned prefix length should be no less than the value of <prefix-length>
Command Mode:
Global Mode.
Default:
No IPv6 prefix delegation address pool is configured by default.
Usage Guide:
This command should be used with the “prefix delegation pool” command to allocate address
prefixes to the clients. If IPv6 prefix delegation is removed, the associated “prefix delegation”
command will be in-effective either.
