interface using four hexadecimal bytes. For example, a virtual frame relay
interface labeled 1 would have a FR_PORT# of 00:00:00:01.
The Q.922 ADDRESS field is populated using the following:
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 address:
DLCI (decimal) / Q.922 address (hex)
16 / 0x0401
50 / 0x0C21
60 / 0x0CC1
70 / 0x1061
80 / 0x1401

Functional Notes
DHCP allows interfaces to acquire a dynamically assigned IP address from a configured DHCP server on the
network. Many Internet Service Providers (ISPs) require the use of DHCP when connecting to their services.
Using DHCP reduces the number of dedicated IP addresses the ISP must obtain. Consult your ISP to
determine the proper values for the
client-id
and
hostname
fields.
