Syntax

Clears DHCPv6 server lease information. The DHCPv6 server must be disabled before clearing lease information.

Command context

Manager (#)

Parameters

all-vrfs: Clears leases for all VRFs.
<IPV6-ADDR> vrf <VRF-NAME>: Clears the lease for a specific client on a specific VRF. Specify the client address in IPv6 format (xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx), where x is a hexadecimal number from 0 to F. You can use two colons (::) to represent consecutive zeros (but only once), remove leading zeros, and collapse a hextet of four zeros to a single 0. For example, this address 2222:0000:3333:0000:0000:0000:4444:0055 becomes 2222:0:3333::4444:55.
vrf <VRF-NAME>: Clears leases for a specific VRF.
