This chapter describes how to configure the Session Manager features in Cisco NX-OS.

This chapter includes the following sections:

Information About Session Manager

Session Manager allows you to implement your configuration changes in batch mode. Session Manager works in the following phases:

  • Configuration session—Create a list of commands that you want to implement in session manager mode.
  • Validation—Provides a basic semantic check on your configuration. Cisco NX-OS returns an error if the semantic check fails on any part of the configuration.
  • Verification—Verifies the configuration as a whole, based on the existing hardware and software configuration and resources. Cisco NX-OS returns an error if the configuration does not pass this verification phase.
  • Commit—Cisco NX-OS verifies the complete configuration and implements the changes atomically to the device. If a failure occurs, Cisco NX-OS reverts to the original configuration.
  • Abort—Discards the configuration changes before implementation.

You can optionally end a configuration session without committing the changes. You can also save a configuration session.

Configuration Guidelines and Limitations

Session Manager has the following configuration guidelines and limitations:

  • Session Manager supports only the ACL feature.
  • You can create up to 32 configuration sessions.
  • You can configure a maximum of 20K commands across all sessions.

Configuring Session Manager

This section includes the following topics:

Creating a Session

You can create up to 32 configuration sessions.

 

Command
Purpose

Step 1

switch# configure session name

Creates a configuration session and enters session configuration mode. The name can be any alphanumeric string.

Step 2

switch(config-s)# show configuration session [ name ]

(Optional) Displays the contents of the session.

Step 3

switch(config-s)# save location

(Optional) Saves the session to a file. The location can be in bootflash or volatile.

Configuring ACLs in a Session

You can configure ACLs within a configuration session.

 

Command
Purpose

Step 1

switch# configure session name

Creates a configuration session and enters session configuration mode. The name can be any alphanumeric string.

Step 2

switch(config-s)# ip access-list name

Creates an ACL.

Step 3

switch(config-s-acl)# permit protocol source destination

(Optional) Adds a permit statement to the ACL.

Step 4

switch(config-s-acl)# interface interface-type number

Enters interface configuration mode.

Step 5

switch(config-s-if)# ip port access-group name in

Adds a port access group to the interface.

Step 6

switch# show configuration session [ name ]

(Optional) Displays the contents of the session.

Verifying a Session

To verify a session, use the following command in session mode.

 

Command
Purpose

switch(config-s)# verify [ verbose ]

Verifies the commands in the configuration session.

Committing a Session

To commit a session, use the following command in session mode.

 

Command
Purpose

switch(config-s)# commit [ verbose ]

Commits the commands in the configuration session.

Saving a Session

To save a session, use the following command in session mode.

 

Command
Purpose

switch(config-s)# save location

(Optional) Saves the session to a file. The location can be in bootflash or volatile.

Discarding a Session

To discard a session, use the following command in session mode.

 

Command
Purpose

switch(config-s)# abort

Discards the configuration session without applying the commands.

Session Manager Example Configuration

This example creates a configuration session for ACLs:

switch# configure session name test2
switch(config-s)# ip access-list acl2
switch(config-s-acl)# permit tcp any any
switch(config-s-acl)# exit
switch(config-s)# interface Ethernet 1/4
switch(config-s-ip)# ip port access-group acl2 in
switch(config-s-ip)# exit
switch(config-s)# verify
switch(config-s)# exit
switch# show configuration session test2

Verifying Session Manager Configuration

To verify Session Manager configuration information, use the following commands:

 

Command
Purpose

show configuration session [ name ]

Displays the contents of the configuration session.

show configuration session status [ name ]

Displays the status of the configuration session.

show configuration session summary

Displays a summary of all the configuration session.
