What is the hostname used for?

Hello,

 

Doing a setup of new bigips and I need to add a hostname. What is the hostname/host ip used for? I picked 'use management port IP' for Host address.

 

We would like heartbeat and clustering/peering to go over a specific VLAN/interface.

 

Thank you.

    I think so too

     

    If I have hostname "bigip-01.f5.com"

     

    and mgmt IP is default [192.168.1.245]

     

    and host ip is [10.10.10.10]

     

    I can't do anything with 10.10.10.10 either manage or ping or else. dns lookup is not found too.

     

    What host ip use for?

    The hostname is just the linux hostname, so it it appears in the commandline prompt, in the log files, and would typically be the name that your DNS server knows the device as.

     

    A device-name (which is often set to the same as the hostname) is the name used for device trust, which leads to configsync and failover.

     

    If you follow the setup wizard, you will be prompted for details of the HA vlan. If you're doing it manually, the config-sync and unicast failover addresses are specified under Device Management / Device / (Self) / Device Connectivity
