display ipv6 prefix
Function
The display ipv6 prefix command displays IPv6 prefix pool configurations.
This command is supported only on the NetEngine 8000 F1A.
Parameters
| Parameter | Description | Value |
|---|---|---|
| prefix-name |
Specifies the name of an IPv6 prefix pool. If this parameter is not specified, this command displays key configurations of all IPv6 prefix pools. |
The value is a string of 1 to 32 case-insensitive characters. |
| all |
Displays detailed information about a specified IPv6 prefix pool and the use of all IPv6 prefixes in that pool. |
- |
| used |
Displays detailed information about a specified IPv6 prefix pool and all IPv6 prefixes in use. |
- |
| reserved |
Displays information about address or prefix reservation in a prefix pool. |
- |
| mac |
Query based on MAC addresses. |
- |
| duid |
Query based on DUID. |
- |
| start-ipv6-prefix |
Specifies the start IPv6 prefix in a specific IPv6 prefix pool. |
The value is in the format of X:X::X:X. Each X is a four-digit hexadecimal number. |
| end-ipv6-prefix |
Specifies the end IPv6 prefix in a specific IPv6 prefix pool. |
The value is in the format of X:X::X:X. Each X is a four-digit hexadecimal number. |
Usage Guidelines
Usage Scenario
To check configurations of all IPv6 prefix pools or a specific one, run the display ipv6 prefix command.
If the name of an IPv6 prefix pool is specified, but not 'all' or 'used', this command displays detailed information about the specified IPv6 prefix pool and statistics about IPv6 prefixes in the pool. If both the start and end IPv6 prefixes are specified to define a range of prefixes in a pool, this command displays detailed information about the specified IPv6 prefix pool and statistics about the range of prefixes.If the start IPv6 prefix, not the end IPv6 prefix, is specified, this command displays statistics about IPv6 prefixes in all prefix ranges starting with the specified IPv6 prefix. If this command is run during user login or logout, the displayed statistics and address usage information may be different from the actual access user statistics. You are advised to view the corresponding information after user access is stable.Prerequisites
The prefix pools to be queried have been configured.
Precautions
In VS mode, this command applies only to the admin VS.
