MASK DGS-1520 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Specifies the hexadecimal bit mask for the masking of the pattern. The masked pattern bits will be matched. If the mask is not specified, all the bits specified by the pattern will be checked. The bit set as 1 will be checked. The input format should be the same as the pattern. The mask of every byte only supports 00 or FF. Default None. Command Mode DHCP Class Configuration Mode. Command Default Level Level: 12. Usage Guideline The user can use the ip dhcp class command with the option hex command to define a DHCP class. The classes in a pool are matched in the order that the class is configured in a pool. With the option hex command, the user can 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 patterns of a DHCP class, the packet will be classified to the DHCP class and forwarded based on the specified target. The following are some commonly used option codes: • Option 60 (Vendor Class Identifier). • Option 61 (Client Identifier). • Option 77 (User Class). • Option 82 (Relay Agent Information Option). • Option 124 (Vendor-identifying Vendor Class). • Option 125 (Vendor-identifying Vendor-specific Information). Example This example shows how to configure the DHCP class Service-A with DHCP Option 60 matching patterns 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)# This example shows how to configure the DHCP class Service-B with DHCP Option 60 matching patterns 0x5566 * and 0x5060 *. Switch#configure terminal Switch(config)#ip dhcp class Service-B Switch(config-dhcp-class)#option 60 hex 5566 * Switch(config-dhcp-class)#option 60 hex 5060 * Switch(config-dhcp-class)# This example shows how to configure the DHCP class Service-C with a DHCP Option 60 matching pattern 0x506007 with a bitmask of 00FF00. 216
