Cisco ISE Deployment Terminology

The following terms are commonly used when discussing Cisco ISE deployment scenarios:

Service: A service is a specific feature that a persona provides, such as network access, profiler, posture, security group access, monitoring and troubleshooting, and so on.
Node: A node is an individual instance that runs the Cisco ISE software. Cisco ISE is available as an appliance and also as software that can be run on VMware. Each instance (appliance or VMware) that runs the Cisco ISE software is called a node.
Persona: The persona of a node determines the services provided by the node. A Cisco ISE node can assume any of the following personas: Administration, Policy Service, Monitoring, and pxGrid. The menu options that are available through the Admin portal are dependent on the role and personas that a Cisco ISE node assumes.
Deployment Model: Determines if your deployment is distributed, standalone, or high availability in standalone, which is a basic two-node deployment.

You Should Know:

1. Basic Cisco ISE Commands

To manage Cisco ISE, you need to be familiar with some basic commands. Here are a few essential ones:

Check ISE Version:
```
show version
```
This command displays the current version of Cisco ISE running on the node.
Restart ISE Services:
```
application start ise
application stop ise
```
These commands are used to start and stop Cisco ISE services.
Check Node Status:
```
show application status ise
```
This command provides the status of all ISE services running on the node.
Backup Configuration:
```
backup-config
```
This command is used to back up the current configuration of the Cisco ISE node.

2. Deployment Models

Cisco ISE supports various deployment models. Here’s how you can configure them:

Standalone Deployment:
```
setup
```
This command initiates the setup wizard for a standalone deployment.
Distributed Deployment:
```
setup distributed
```
Use this command to configure a distributed deployment model.
High Availability (HA) Deployment:
```
setup ha
```
This command is used to configure a high availability deployment.

3. Monitoring and Troubleshooting

Cisco ISE provides robust monitoring and troubleshooting tools. Here are some commands to help you:

View Logs:
```
show logging
```
This command displays the system logs, which can be useful for troubleshooting.
Check Network Connectivity:
```
ping <IP-address>
```
Use this command to check network connectivity between nodes.
Check CPU and Memory Usage:
```
show process cpu
show process memory
```
These commands help you monitor the CPU and memory usage of the ISE node.

4. VMware-Specific Commands

If you’re running Cisco ISE on VMware, these commands might be useful:

Check VMware Version:
```
vmware -v
```
This command displays the version of VMware running on the host.
Restart VMware Services:
```
service vmware restart
```

Use this command to restart VMware services.
