Reasons Why an Analog Modem Interface
Configuration May Be Read-Only
A previously configured analog modem interface or will be read-only and will not
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
