Deleting an ISDN Configuration Entry

The isdnd command is used to delete one or more ISDN configuration entries. Deleting the
configuration entry is equivalent to returning the ISDN port to its default settings. Although
you cannot delete a physical ISDN port from the switch, you can remove the configuration
entry that was recorded for a port.
1. To delete a specific ISDN entry, for example, for a board in slot/port 2/2, you would enter
the following command:
isdnd 2/2
A screen similar to the following displays:
This will delete Slot 2, Port 2.
Continue ? {(Y)es, (N)o} : N
2. To delete this entry, enter y and press Enter. To abort the deletion, press Enter to accept
the default answer of “No.” The system prompt will then reappear.
Important Note
After deleting an ISDN configuration entry, you should
reboot the switch to implement any configuration
changes you make using the isdnm command.
