NimbostratusHow to setup F5 LTM HA network
Hi Expert
I'm new to F5. Can anyone let me know how to connect two F5 LTM for HA setup?. Below are available ports on my F5 LTM. There is a port with the name FAILOVER bottom. How can i connect ...
Agree with nitass, don't use failover port. A number of limitations and basically no worthwhile advantages
I'd use both 1G interfaces that are already populated with GbE SFPs for HA, configured as LACP Port Trunk. You will need more SFPs for data though.
Observing the ports available, you cannot evenly allocate remaining ports for segregated client-side and server-side LACP bundles. So I'd bundle 2x 10G interfaces as LACP port trunk for data, and use this 20G link for both, client-side and server-side VLANs.
Here's summary
- 2x 1G interfaces directly to other unit for HA functions. Config sync, Network failover, Traffic mirror
- 2x 10G to network switch stack. All client-side and serve-side traffic
- Mgmt to network switch (ideally dedicated management switch). SSH and HTTPS (GUI)

Employeeit is hard wire failover port. i rarely use it nowadays since network failover has much more functionalities.

Shamsul_Alam_34Thank you for your response. I will consider to implement Network fail over.
