To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
The ppp chap password command is sent in CHAP responses and is used by the peer to authenticate the
local router. This does not affect local authentication of the peer. This command is useful for routers that do
not support this command (such as routers running older Cisco IOS XR images).
The CHAP secret password is used by the routers in response to challenges from an unknown peer.
