■
A DHCP relay server has been set on the switch, when the switch
receives a DHCP request packet with a non-zero relay agent
address field (that is not the address of this switch).
■
A DHCP relay server has been set on the switch, when the switch
receives DHCP reply packet without option 82 information from the
management VLAN.
■
The reply packet contains a valid relay agent address field (that is
not the address of this switch), or receives a reply packet with a
zero relay agent address through the management VLAN.
■
A DHCP relay server has been set on the switch, and the switch
receives a reply packet on a non-management VLAN.
P
ARAMETERS
These parameters are displayed:
◆
Insertion of Relay Information
– Enable DHCP Option 82
information relay. (Default: Disabled)
◆
DHCP Option Policy
– Specifies how to handle client requests which
already contain DHCP Option 82 information:
Drop
- Floods the original request packet onto the VLAN that
received it instead of relaying it. (This is the default.)
Keep
- Retains the Option 82 information in the client request,
inserts the relay agent’s address, and unicasts the packet to the
DHCP server.
Replace
- Replaces the Option 82 information circuit-id and
remote-id fields in the client’s request with information provided by
the relay agent itself, inserts the relay agent’s address, and unicasts
the packet to the DHCP server.
◆
DHCP Sub-option Format
– Specifies whether or not to use the
sub-type and sub-length fields in the circuit-ID (CID) and remote-ID
(RID) in Option 82 information. (Default: Included)
◆
DHCP Remote ID Sub-option
– Specifies the format used to identify
this switch as the DHCP relay agent to the DHCP server:
■
MAC Address
- Includes a MAC address field for the relay agent
(that is, the MAC address of the switch’s CPU). This attribute can be
encoded in hexadecimal or ASCII.
■
IP Address
- Includes the IP address field for the relay agent (that
is, the IP address of the management interface). This attribute can
be encoded in hexadecimal or ASCII.
■
String
- An arbitrary string inserted into the remote identifier field.
