DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Parameters CODE PATTERN * MASK Specifies the DHCP option number. Specifies the hex pattern of the specified DHCP option. (Optional) Specifies not to match the remaining bits of the option. If not specified, the bit length of the PATTERN should be the same as the bit length of the option. (Optional) Specifies the hex bit mask for masking of the pattern. The masked pattern bits will be matched. If not specified, all bits specified by PATTERN will be checked. The bit set to FF will be checked. The input format should be the same as PATTERN. Default None. Command Mode DHCP Class Configuration Mode. Usage Guideline Use the ip dhcp class command with this command to define a DHCP class. The classes in a pool are matched in the sequence of the class configuration in a pool. Use the option hex command to specify the DHCP option code number with its matching pattern for a DHCP class. Multiple option patterns can be specified for a DHCP class. If the packet matches any of the specified pattern of a DHCP class, the packet will be classified to the DHCP class and forwarded based on the specified target. The following are some common used option codes:  Option 60 - Vendor class identifier.  Option 61 - Client identifier.  Option 77 - User class.  Option 124 - Vendor-identifying vendor class.  Option 125 - Vendor-identifying vendor-specific information. Example This example shows how to configure a DHCP class "Service-A" and defined with DHCP Option 60 matching pattern 0x112233 and 0x102030. Switch# configure terminal Switch(config)# ip dhcp class Service-A Switch(config-dhcp-class)# option 60 hex 112233 Switch(config-dhcp-class)# option 60 hex 102030 Switch(config-dhcp-class)# 15-19 relay destination This command is used to specify the DHCP relay destination IP address associated with a relay pool. Use the no form of this command to delete a DHCP relay destination from the DHCP relay pool. relay destination IP-ADDRESS no relay destination IP-ADDRESS 117

DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide
117
Parameters
CODE
Specifies the DHCP option number.
PATTERN
Specifies the hex pattern of the specified DHCP option.
*
(Optional) Specifies not to match the remaining bits of the option. If not specified,
the bit length of the PATTERN should be the same as the bit length of the option.
MASK
(Optional) Specifies the hex bit mask for masking of the pattern. The masked
pattern bits will be matched. If not specified, all bits specified by PATTERN will
be checked. The bit set to FF will be checked. The input format should be the
same as PATTERN.
Default
None.
Command Mode
DHCP Class Configuration Mode.
Usage Guideline
Use the
ip dhcp class command
with this command to define a DHCP class. The classes in a pool are matched
in the sequence of the class configuration in a pool.
Use the
option hex
command to specify the DHCP option code number with its matching pattern for a DHCP
class. Multiple option patterns can be specified for a DHCP class. If the packet matches any of the specified
pattern of a DHCP class, the packet will be classified to the DHCP class and forwarded based on the specified
target.
The following are some common used option codes:
Option 60
- Vendor class identifier.
Option 61
- Client identifier.
Option 77
- User class.
Option 124
- Vendor-identifying vendor class.
Option 125
- Vendor-identifying vendor-specific information.
Example
This example shows how to configure
a DHCP class “Service
-
A” and defined with DHCP
Option 60 matching
pattern 0x112233 and 0x102030.
Switch# configure terminal
Switch(config)# ip dhcp class Service-A
Switch(config-dhcp-class)# option 60 hex 112233
Switch(config-dhcp-class)# option 60 hex 102030
Switch(config-dhcp-class)#
15-19 relay destination
This command is used to specify the DHCP relay destination IP address associated with a relay pool. Use the
no
form of this command to delete a DHCP relay destination from the DHCP relay pool.
