OmniAccess 5740 Unified Services Gateway CLI Configuration Guide
IP CONTROL PROTOCOL (IPCP) CONFIGURATION
IPCP negotiates IP address assignments. The OmniAccess 5740 USG 
exchanges IPCP messages with the peer for negotiating options relating to IP. 
The IPCP phase occurs after the LCP phase and the optional authentication 
phase.
T
O INITIATE IPCP NEGOTIATION MANUALLY
Note: By default, the OmniAccess 5740 USG system responds to IPCP negotiation initiated 
by the peer. Auto-negotiation happens when the IP address is changed on the 
interface.

XAMPLE
ALU(config-if Serial1/0:0)# ppp ipcp negotiate

ALU(config-if Serial0/0:0)# ppp ipcp address accept-local
ALU(config-if Serial0/0:0)# no ppp ipcp address accept-local
Command (in ICM) Description
ppp ipcp negotiate This command is used to initiate the 
IPCP negotiation on the interface.
Command (in ICM) Description
ppp ipcp address accept-local  This command sets a flag to accept a 
local IP address given to it by the peer 
during IPCP.
By default, the flag is set to reject the 
local IP address from the peer during 
IPCP.
no ppp ipcp address accept-
local
The “no” command sets the flag to reject 
the local IP address given to it by its peer 
during IPCP. This is the default behavior.
