DHCP Unique Identifier Content
A
DHCP (Dynamic Host Configuration Protocol) unique identifier (DUID) consists of a
two-octet type code followed by a variable number of octets that make up the actual identifier. A
DUID can be no more than 128 octets long (not including the type code). The following types are
currently defined:
- Link-layer address plus time
- Vendor-assigned unique ID based on Enterprise Number
- Link-layer address
ExtremeXOS uses Link-layer address plus time as its default client DUID. To
configure DHCPv6 client identifier type for the client use:
configure dhcp ipv6 client identifier-type [ link-layer |
link-layer-plus-time | vendor-specific ]
