== Viewing System Information ==
To display system information, including the software version, platform, and other relevant details, use the following command:

<nowiki>
tmsh show sys version</nowiki>

This command will output the software version, platform type, and more.

== Managing Configuration Files ==
You can list, view, and manage system configuration files. The command below displays all configuration files:

<nowiki>
tmsh list /sys config</nowiki>

To view a specific configuration file, use:

<nowiki>
tmsh show /sys config <filename></nowiki>

== Viewing System Status ==
To view the overall status of the system, including all major components, run:

<nowiki>
tmsh show sys status</nowiki>

This shows the status of hardware, software, and critical system components.

== Network Configuration ==

=== Viewing Network Interfaces ===
To list the available network interfaces, run:

<nowiki>
tmsh show net interface</nowiki>

This command displays all physical interfaces and their status, including throughput and error counts.

=== Configuring Network Interfaces ===
To configure a specific network interface, use the following command:

<nowiki>
tmsh modify /net interface <interface_name> mtu <mtu_value> address <ip_address> netmask <netmask_value></nowiki>

For example, configuring `eth0` with an MTU of 1500, IP address `192.168.1.10`, and netmask `255.255.255.0` would be:

<nowiki>
tmsh modify /net interface eth0 mtu 1500 address 192.168.1.10 netmask 255.255.255.0</nowiki>

=== Viewing Routing Information ===
To show routing information, including routes, use:

<nowiki>
tmsh show net route</nowiki>

This command outputs the active routes in the routing table.

== LTM (Local Traffic Manager) Configuration ==

=== Viewing Pools ===
To view the configuration and status of load balancing pools, use:

<nowiki>
tmsh show ltm pool</nowiki>

This command provides a list of all configured pools, along with their status, members, and other relevant details.

=== Creating and Managing Pools ===
To create a new pool, the following command can be used:

<nowiki>
tmsh create ltm pool <pool_name> members add { <ip_address>:<port> }</nowiki>

For example:

<nowiki>
tmsh create ltm pool mypool members add { 192.168.1.20:80 192.168.1.21:80 }</nowiki>

To modify a pool, use the `modify` keyword, and to delete a pool, use the `delete` keyword:

<nowiki>
tmsh modify ltm pool mypool members add { 192.168.1.22:80 }
tmsh delete ltm pool mypool</nowiki>

=== Viewing Virtual Servers ===
To list the virtual servers and their statuses:

<nowiki>
tmsh show ltm virtual</nowiki>

This shows the configured virtual servers, their IP addresses, and their current status.

=== Creating and Managing Virtual Servers ===
To create a new virtual server, the following command is used:

<nowiki>
tmsh create ltm virtual <vs_name> destination <vs_ip>:<vs_port> pool <pool_name> profiles add { http }</nowiki>

For example:

<nowiki>
tmsh create ltm virtual myvirtualserver destination 192.168.1.100:80 pool mypool profiles add { http }</nowiki>

To modify or delete a virtual server, use the `modify` and `delete` commands respectively:

<nowiki>
tmsh modify ltm virtual myvirtualserver destination 192.168.1.101:80
tmsh delete ltm virtual myvirtualserver</nowiki>

== SSL Configuration ==

=== Viewing SSL Profiles ===
To display SSL profile configurations, use the following command:

<nowiki>
tmsh show ltm profile client-ssl</nowiki>

This command lists the SSL profiles used by virtual servers for handling encrypted traffic.

=== Creating and Managing SSL Profiles ===
To create an SSL client profile, use:

<nowiki>
tmsh create ltm profile client-ssl <profile_name> cert <cert_file> key <key_file> options <ssl_options></nowiki>

For example:

<nowiki>
tmsh create ltm profile client-ssl mysslprofile cert /config/ssl/certs/mycert.crt key /config/ssl/keys/mykey.key options { no-ssl-verify }</nowiki>

=== Viewing SSL Certificates ===
To display SSL certificates:

<nowiki>
tmsh show sys crypto cert</nowiki>

This command lists all the certificates installed on the system.

== Traffic and Session Management ==

=== Viewing Active Connections ===
To view active connections on the system, run:

<nowiki>
tmsh show sys connection</nowiki>

<nowiki>
tcpdump -i <interface_name> -w /var/tmp/capture.pcap</nowiki>

For example, to capture packets on interface `eth0`:

<nowiki>
tcpdump -i eth0 -w /var/tmp/capture.pcap</nowiki>

== System Logs ==

<nowiki>
tmsh show sys event</nowiki>

This command shows a list of system events and their details.

== Troubleshooting ==

=== Checking System Performance ===
To check the system's performance, including CPU and memory usage:

<nowiki>
tmsh show sys performance</nowiki>

This will display CPU and memory usage, as well as disk and network performance.

=== Checking System Health ===
To check the health status of various system components:

<nowiki>
tmsh show sys health</nowiki>

This command gives an overview of the system's health, including hardware status, disk health, and more.
