SROS Command Line Interface Reference Guide DHCP Pool Command Set

The Q.922 ADDRESS field is populated using the following:

8	7	6	5	4	3	2	1
DLCI (high order)						C/R	EA
DLCI (lower)				FECN	BECN	DE	EA

Where the FECN, BECN, C/R, DE, and high order EA bits are assumed to be 0, and the lower order extended address (EA) bit is set to 1.

The following list provides a few example DLCIs and associated Q.922 addresses:

DLCI (decimal) / Q.922 address (hex) 16 / 0x0401

50 / 0x0C21

60 / 0x0CC1

70 / 0x1061

80 / 0x1401

Command Modes

(config-dhcp)# DHCP Pool

Functional Notes

DHCP clients use client-identifiers in place of hardware addresses. To create the client-identifier, begin with the two-digit numerical code representing the media type and append the client’s MAC address. For example, a Microsoft client with an Ethernet (01) MAC address d2:17:04:91:11:50 uses a client-identifier of 01:d2:17:04:91:11:50.

Usage Examples

The following example specifies the client-identifier for a Microsoft client with an Ethernet MAC address of d217.0491.1150:

(config)#ip dhcp-server pool Microsoft_Clients (config-dhcp)#client-identifier 01:d2:17:04:91:11:50
