set bootp relay option82 port
Syntax SET BOOTp RELAy OPTion82 POrt={port-list|ALL}
[SUBScriberid=subscriber-id]
[TRusted={YES|NO|ON|OFF|True|False}]
where:
■ port-list is a port number, a range of port numbers (specified as n-m), or a
comma-separated list of port numbers and/or ranges. Port numbers start
at 1 and end at m, where m is the highest numbered Ethernet switch port,
including uplink ports.
■ subscriber-id is a character string from 0 to 50 characters long. Valid
characters are any alphanumeric characters. If string contains spaces, it
must be in double quotes. Wildcards are not allowed.
Description This command defines the DHCP Relay Agent port settings for DHCP Option
82. When Option 82 is enabled, the Relay Agent inserts Option 82 information
into the DHCP options field when forwarding client-originated
BOOTP/DHCP packets to a DHCP server. Option 82 must be enabled with the
enable bootprelay option 82 command for the port settings you specify to take
effect.
Use the port parameter to specify the port to use for this command. If all is
specified, this command is applied to all ports on the device.
Use the subscriberid parameter to specify the subscriber-ID for the port
defined in port=. If specified, the subscriber-ID sub-option is included in the
Option 82 field of client DHCP packets received on the specified port. The
default is no subscriber-ID.
NOTE If you specify an empty string in the subscriberid parameter, then the
subscriber-ID sub-option is not included in the Option 82 field of client DHCP
packets forwarded from the specified port. Use this method to delete a
subscriber-ID from a port.
Use the trusted parameter to specify how the router or switch handles client
DHCP packets that contain Option 82 information, but which have the giaddr
field set to 0. If you specify yes, the defined port is considered to be a trusted
source of Option 82 information, and packets with Option 82 information and a
giaddr of 0 are forwarded according to normal BOOTP Relay operation. The
values yes, on, and true are equivalent. If you specify no, packets are dropped
that contain DHCP Option 82 information and with the giaddr field set to 0.
The values no, off, and false are equivalent. The default is no.
Example To set all ports as trusted, use the command:
set boot rela opt po=all tr=yes
