Reasons Why an Analog Modem Interface
Configuration May Be Read-Only
A previously configured analog modem interface or will be read-only and will n ot
be configurable in the following cases:
An IP address is assigned to the asynchronous interface.
Encapsulation other than ppp is configured on the asynchronous interface.
The dialer-group or dialer string command is configured on the
asynchronous interface.
Async mode interactive is configured on the asynchronous interface.
dialer pool-member <x> is configured on the asynchronous interface, but
the corresponding dialer interface <x> is not present.
Multiple dialer pool-members are configured on the asynchronous interface.
Encapsulation other than ppp is configured on the dialer interface.
Either dialer-group or dialer-pool is not configured on the dialer interface.
dialer-group <x> is configured on the dialer interface, but the corresponding
dialer -list <x> protocol command is not configured.
dialer idle-timeout <num> with optional keyword (either/inbound) is
configured on the dialer interface.
In line configuration collection mode, modem inout is not configured.
In line configuration collection mode, autoselect ppp is not configured.
If using the analog modem connection as a backup connection, once the
backup configuration is through Cisco SDM, if any of the conditions below
occur, the backup connection will be shown as read only:
The default route through the primary interface is removed
The backup interface default route is not configured
ip local policy is removed
