Incomplete HWaddress in Dynamic ARP of BIGIP F5

Hi all,

I setup a F5 on VMware and i configured below settings:

1. Management IP : 10.208.107.8/26 with Default Gateway : 10.208.107.1
2. created Vlan 606 and Tag it with interface 1.1 and i cross checked the MAC address of VM network adapter with F5 interface (Both matched).
3. created self IP and assigned Vlan 606 to it with IP 10.208.108.5/26.
4. Routes: Destination 0/0 and Gateway: 10.208.108.2
5. Added one server in (Local traffic -> Nodes) which is showing down (IP: 10.208.108.9) (Monitoring ICMP)

Note: whenever i remove Self-IP, the server comes UP.

The problem is i am unable to get ARP of Self-IP on my FW.

Unable to ping 10.208.108.9 Node from F5

Network - ARP - Dynamic ARP --- Here it is showing me 10.208.108.9 & 10.208.108.2 but in MAC address section it is showing "incomplete"

As i am not getting ARP, Self-IP and Nodes are not able to communicate.

What i suspect is the Media Speed of F5 interface is 10000 , auto

Interface configured on FW with vlan 606 has BW 1000 Mbps.

I tried to change F5 interface media speed to 1000 by using "modify net interface 1.1 media 1000T-FD", it given an error:

"invalid property vlaue "media":"1000T-FD" The requested media is invalid, valid settings are: 10000T-FD, auto. please see SOL14556 for details.

Question:

1. Is the Mismatch of media speed is causing the ARP issue ?
2. Have i missed some configuration which is causing this ?

Please suggest a solution as i need to get this resolved asap.

I can also show my settings on a ZOOM session, if someone is willing to help.

Thanks in Advance.
