Common Management Layer Commands
This chapter is a reference for the Common Management Layer (CML) commands.
Transaction are enabled by default. You can disable the feature by using the cmlsh transaction command outside of configuration mode, but IP Infusion Inc. does not recommend this.
These are the steps to follow to use transactions:
• When transactions are enabled, any changes done in configure mode are stored in a separate candidate configuration that you can view with the show transaction current command.
• When a configuration is complete, apply the candidate configuration to the running configuration with the commit command.
• If a commit fails, no configuration is applied as the entire transaction is considered failed. You can continue to change the candidate configuration and then retry the commit.
• Discard the candidate configuration with the abort transaction command.
• Check the last aborted transaction with the show transaction last-aborted command.
• For the detailed description about Commit Rollback functionality, refer to the Commit Rollback section in the OcNOS Key Feature document, Release 6.4.1.
This chapter describes these commands:
• commit
• commit dry-run

cml force-unlock config-datastore
Use this command to release a configuration lock previously obtained with the cml lock config-datastore command by a different user.
This command is available only to users with the network-admin role.
A notification message is sent to the lock holder when forced out.
Command Syntax
cml force-unlock config-datastore (running|startup|candidate) (<0-600>|)
Parameters
<0-600>
Timeout interval to force out lock acquired by another user session. Zero (0) is immediate and is the default.
running
Release the lock on the running datastore.
startup
Release the lock on the startup datastore.
candidate
Release the lock on the candidate datastore.
Default
The default timeout is zero (0) which is immediate.
Mode
Exec mode
Applicability
This command was introduced in OcNOS version 5.1.
Example
#cml force-unlock config-datastore running
cml lock config-datastore
Use this command to lock the entire configuration datastore of a device. Such locks are intended to be short-lived and allow you to make a change without fear of interaction with other users.
When the lock is acquired, the server prevents any changes to the locked resource other than those requested by this session.
The duration of the lock is defined as beginning when the lock is acquired and lasting until either the lock is released or the user session closes. The session closure can be explicitly performed by the user, or implicitly performed by the server based on criteria such as failure of the underlying transport, simple inactivity timeout, or detection of abusive behavior on the part of the client.
A lock will not be granted if any of the following conditions is true:
• A lock is already held by any user session or another entity.
• The target configuration is candidate, it has already been modified, and these changes have not been committed or rolled back.
• The target configuration is running, and another user session has an ongoing confirmed commit.
Command Syntax
cml lock config-datastore (running|startup|candidate)
Parameters
running
Lock on this datastore will not allow other sessions to perform operations with the target as running like commit, copy candidate to running and so on.
startup
Lock on this datastore will not allow other sessions to perform operations like copy-config and delete-config with the target startup
candidate
Lock on this datastore will not allow other sessions to perform operations with the target as candidate like edit-config, copy file candidate and so on. (Not supported in OcNOS version 5.1.)
Default
All three datastores are in the unlocked state.
Mode
Exec mode
Applicability
This command was introduced in OcNOS version 5.1.

cmlsh cli-format
Use this command to display command strings in CLI error messages. By default, OcNOS displays error messages with Xpaths (path notation for navigating through the hierarchical structure of an XML document) which is not very clear for users.
Command Syntax
cmlsh cli-format (enable | disable)
Parameters
enable
Display command strings in CLI error messages.
disble
Display Xpaths in CLI error messages.
Default
Display Xpaths in CLI error messages
Mode
Exec mode
Applicability
This command was introduced in OcNOS version 6.3.0.
Example
This is the default behavior where an Xpath is displayed:
>en
#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
(config)#router ospf 10
(config-router)#area 3.3.3.3 interface xe1
(config-router)#commit
% Configuration " /ospfv2/processes/process[ospf-id='10']/areas/area[area-id='3.3.3.3']/interfaces/interface[name='xe1']/vrf-name" depends on "/ospfv2/global/config/area-interface-config-mode"
% Failed to commit .. As error(s) encountered during commit operation…
If you enable this feature, the Xpath is replaced with the respective command string:
>en
#cmlsh cli-format enable
#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
(config)#router ospf 10
(config-router)#area 3.3.3.3 interface xe1
(config-router)#commit
% Configuration " area <value-option> interface <value-option>" depends on " ospf area-interface-config-mode"
% Failed to commit .. As error(s) encountered during commit operation…
cmlsh multiple-config-session
Use this command to enable or disable multiple CLI sessions to enter into configuration mode simultaneously.
With this support, multiple CLI users can enter into configuration mode simultaneously and do configurations in parallel and commit into the running datastore. This is similar to NetConf multiple session support described in RFC 6241.
When multiple configuration mode sessions are disabled, only one user can enter configuration mode and it will lock the running datastore.
If any CLI session is already there in configuration mode, error will be given when user tries to enable this mode.
A datastore lock can be acquired using the cml lock config-datastore command if you want to do configuration without fear of interaction with other user sessions.
This command is available only to users with the network-admin role.
This configuration is retained across reboots.
Command Syntax
cmlsh multiple-config-session (enable|disable)
Parameters
enable
Enable multiple configuration mode sessions.
disable
Disable multiple configuration mode sessions.
Default
By default, multiple CLI sessions are disabled.
Mode
Exec mode
Applicability
This command was introduced in OcNOS version 5.1.
Example
#cmlsh multiple-config-session enable
#
#show cmlsh multiple-config-session status
CMLSh multiple configuration session mode : Enabled
#
Usage
Multiple users can enter into configuration mode simultaneously and do configurations in parallel and commit into the running datastore. Examples of when you need this feature are:
• Migrating to replace an existing device. If an existing device has a large configuration and it is only done by one person, it will take more time to configure. If multiple users can configure at same time, it will take less time.
• Troubleshooting and operating. Sometimes a single device has 2 or more links to troubleshoot. If only one user only can do configuration, it will take more time to resolve the problem.
When multiple sessions are doing parallel configurations, there is a chance that one user’s configuration might conflict with another user’s configuration.
If you do not lock the datastore before doing a configuration, a parallel candidate datastore can be created and will be allowed to commit to the datastore. So the datastore can change while the previous user is still having the configuration in its candidate. Now when the previous user tries to commit, if the configurations conflict, it will fail.
For example, if the previous user was adding a BGP neighbor and the BGP router itself is removed from the datastore via the parallel transaction, when this user tries to commit, it will fail. The reason is when commands are added to candidate, it only checks the running datastore at that point and allows them to be added to candidate configuration datastore. But later if the running datastore itself is changed, these configurations can be irrelevant and will cause an error on commit. So the user will have to abort the transaction.
cmlsh notification
Use this command to enable or disable notification for the current CMLSH session.
Command Syntax
cmlsh notification (enable|disable)
Parameters
disable
Disable notification subscription for current CMLSH session
enable

Note: IP Infusion Inc. recommends that you do not disable transactions.
Command Syntax
cmlsh transaction (enable | disable)
Parameters
enable
Enable transaction-based command-line interface
disable
Disable transaction-based command-line interface
Default
The transaction-based command-line interface is enabled by default.
Mode
Exec mode
Applicability
This command was introduced in OcNOS version 5.0.
Example
>en
#cmlsh transaction disable
% Deprecated CLI. Disabling transaction mode is not recommended

(config-router)#exit
(config)#show running-config router ipv6 ospf
!
router ipv6 ospf test
!
(config)#
cmlsh transaction limit
Use this command to set the maximum number of transactions.
To verify, give the show max-transaction limit command in exec mode.
Command Syntax
cml transaction limit <0-300000>
Parameters
<0-300000>
Maximum number of transactions with zero (0) indicating unlimited transactions.
Default
300,000 transactions
Mode
Configure mode
Applicability
This command was introduced in OcNOS version 5.0.
Example
(config)#cml transaction limit 1500
(config)#exit
#show max-transaction limit
Max-Transaction Limit is 1500
 
commit
Use this command to commit the candidate configuration to the running configuration.
Note: After a successful commit command, you must give the write command to save the running configuration to the startup configuration.
Note: Multiple configurations cannot be removed with a single commit. You must remove each configuration followed by a commit.
Optionally with “confirmed commit”, you can commit the configuration on a trial basis for a time specified in seconds. If you do not confirm within the specified time, the configuration will be reverted after the timeout.
• To revert the configuration before timeout, then give the cancel-commit command.
• To retain the configuration before timeout, then give the confirm-commit command.
See RFC 6241 “Confirmed Commit Capability”.
Note: A commit command without any parameters is treated as permanent and an explicit confirm-commit command is not required to confirm the commit.
Note: Multiple confirmed commits in the same session or different sessions are not supported. The commit command does not support the <persist-id> parameter as specified in RFC 6241.
Command Syntax
commit (confirmed (timeout <1-500>|)|) (description LINE|)
Parameters
confirmed
Commits the configuration on a trial basis.
<1-500>
Timeout in seconds after which configuration should be reverted if a confirmation is not given with confirm-commit. If not specified, the default timeout is 300 seconds.
LINE
Commit description up to 65 characters
Default
The default timeout is 300 seconds.
Mode
All configuration modes
Applicability
This command was introduced in OcNOS version 5.0 and the confirmed clause added in OcNOS version 6.3.0.
Example
(config)#router ospf 1
(config-router)#exit
(config)#router isis 3
(config-router)#commit
(config-router)#exit
(config)#show running-config ospf
!
router ospf 1
!
(config)#show running-config isis
!
router isis 3
!
(config)#
 
If you try to exit or end, you are prompted to commit or abort first:
(config)#router bgp 10
(config-router)#bgp as-local-count 34
(config-router)#exit
(config)#exit
% Un-committed transactions present. Please do commit or abort before exiting.
(config)#end
% Un-committed transactions present. Please do commit or abort before exiting.
(config)#commit
(config)#show running-config bgp
!
router bgp 10
bgp as-local-count 34
!
(config)#
This is an example of a “confirmed commit”:
(config)#router ospf 1
(config-router)#router ospf 2
(config-router)#commit confirmed timeout 100 description This is Test for confirmed commit
Usage
OcNOS validates dependencies when you commit. In this example, bridge 1 must exist before you can create a VLAN on it:
(config)#vlan database
(config-vlan)#vlan 10 bridge 1
(config-vlan)#exit
(config)commit
Because of the unmet dependency, you get an error when you try to commit.
If you also create the bridge, the commit succeeds:
(config)#bridge 1 protocol mstp
(config)#vlan database
(config-vlan)#vlan 10 bridge 1
(config-vlan)#exit
(config)commit
In a single transaction, dependent configurations can be given in any order. Using the same example as before, you can create the bridge after the VLAN:
(config)#vlan database
(config-vlan)#vlan 10 bridge 1
(config-vlan)#exit
(config)#bridge 1 protocol mstp
(config)commit
OcNOS supports “hitless merges” and does not write to the candidate configuration if you make the same configuration in separate transactions. In this example, subinterface xe1.1 is not created the second time because it already exists:
(config)#interface xe1.1
(config-if)#commit
(config)#interface xe1.1
(config-if)#commit
OcNOS does not write to the candidate configuration if you create and delete the same entity in the same transaction. You must create the entity and delete it with separate commits.
Mode changes, action items (such as clear interface counters), and show commands are not part of a transaction and are not displayed by the show transaction current command.
confirm-commit
Use this command to commit configuration changes before the timeout in a “confirmed commit” operation.
Note: This command does not support the <persist-id> parameter as specified in RFC 6241.
Command Syntax
