Management IP

[Cowboy Denny]

From CLI (command line interface) run the following command to list the current management IP address

tmsh list /sys management-ip

Also check the management route is in place

tmsh list /sys management-route

 

If nothing is configured or you want to change it then follow the below to assign the management IP to your F5 device

tmsh create /sys management-ip [ip address/netmask]

Example:

tmsh create /sys management-ip 10.46.48.13/23

Don't forget to create the management route as well

tmsh create /sys management-route default gateway <gateway ip address>

Example:

tmsh create /sys management-route default gateway 10.46.48.1

 

Now when you run the list command it should look similar to below

tmsh list /sys management-ip
sys management-ip 10.46.48.13/23 {
    description configured-statically
}

tmsh list /sys management-route
sys management-route default {
    gateway 10.46.48.1
    network default
}

The configuration option Network specifies the trap network. Management: Specifies that the system sends the trap out of the management IP address (or the cluster management IP address, if this is a clustered configuration). Other: Specifies that the system sends the trap out of the interface based on the routing tables.

NOTE:  By default, the SNMP trap egresses from the TMM interface if the trap destination is accessible through Management and TMM interfaces. Also, if there is a TMM route and Management route to the same trap destination, the traps will always egress from the TMM interface and not through the Management interface. 

To look at the routing table for both Management and TMM, use the following command:
netstat -nr

To view all existing TMM routes, type the following command:

tmsh show /net route

To view routes in the routing table, main, type the following command:

ip route show table main

To view the management routing table routes (table 245), type the following command:

ip route show table 245

Self IP address is an IP address on the f5 system that you associate with a VLAN, to access hosts in that VLAN

Basically management IP is used to manage f5 device configuration, monitoring SNMP, etc.

By default, the BIG-IP system allows access to the protocols and ports on the management interface listed in the following table.

Service	Port	Protocol	Description
SSH	22	TCP	Secure Shell protocol
HTTPS	443	TCP	Hypertext Transfer Protocol Secure protocol
SNMP	161	TCP	Simple Network Management Protocol
SNMP	161	UDP	Simple Network Management Protocol
F5 HA	1026	UDP	Network failover communication for high availability
F5 iQuery	4353	TCP	iQuery protocol
