Discarding the Changes
If you discard (abort) the changes made to the pending database, the configuration database remains
unaffected and the lock is released.
To discard IVR configuration changes, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# ivr abort
Clearing a Locked Session
If you have performed an IVR task and have forgotten to release the lock by either committing or
discarding the changes, an administrator can release the lock from any switch in the fabric. If the
administrator performs this task, your changes to the pending database are discarded and the fabric lock
is released.
The pending database is only available in the volatile directory and are subject to being discarded if the

switch is restarted.
To use administrative privileges and release a locked DPVM session, use the clear ivr session command
in EXEC mode.
switch# clear ivr session
About IVR NAT
Prior to Cisco MDS SAN-OS Release 2.1(1a), IVR required unique domain IDs for all switches in the
fabric. As of Cisco MDS SAN-OS Release 2.1(1a), you can enable IVR Network Address Translation
(NAT) to allow non-unique domain IDs. This feature simplifies the deployment of IVR in an existing
fabric where non-unique domain IDs might be present.
IVR NAT must be running on all border switches in the fabric IVR configuration distribution. IVR
configuration distribution is supported by the CFS infrastructure (see the
Distribution" section on page

For IVR NAT to function correctly in the network, all IVR-enabled switches must run Cisco MDS
