AltostratusNot able to access GUI and SSH to F5 VM
Hi, I am currently running VM 11.5.3 on a trial version. I configured the HA pair and everything worked fine I was able to access GUI and did the SSH. Now I am trying to run the same VMs with the same configs after 3 days but now I am not able to access GUI and SSH to the device. I ran the VM and their I can see one device is active and other is standby, I checked the config and the IP addresses are same that i have assigned initially. I did the ifconfig (as i am using MAC) and their I verified vmnet1 and vmnet8 are properly configured according to my IPs. I checked the Network adapter and all are connected in host only mode.
Let me know if you have anything else that i can check.
Hi Ian, Don't know what happened but it started to work now. Yesterday when i did the ping from host to VE it was giving me request timed out and today i am able to ping and access the GUI as well. It might be some type of bug i don't know. But thanks for your support

- Make sure you can ping the management address from the virtual machine itself (using the vmware console)
- Run "tcpdump -n -i eth0" (eth0=management port) on the BigIP, and see whether it can see any arp or icmp packets from your host when you try to ping it form the host.

Which mode is selected for vmnet1 and vmnet8 ? Try using 'host-only'. Add the static IPs. Disable the DHCP from Vmware preferences.
Frank_NHi Ian,
I did tcpdump on my Primary console while i was doing ping from secondary. The output that I got is attached below. My primary mgmt ip is 172.16.1.100 and secondary mgmt ip address is 172.16.1.200. I can ping from console to the mgmt IP. From the output it seems like both the mgmt ip are sending packets to each other. Also I ran the following command (tmsh list net arp all) to see the list of arp entries and I can see only HA VLAN entry in it which is 112.112.112.2.Amanpreet, I am using host only mode for both devices. DHCP is disabled and I have configured static IP addresses.
- IanBWhat IP address have you configured on your host ? What does tcpdump see if you try to ping the host from the VE, or the VE from the host ?
- Frank_N
Primary:
Mgmt: 172.16.1.100 255.255.255.0 GW : 172.16.1.1
Secondary:
Mgmt: 172.16.1.200 255.255.255.0 GW : 172.16.1.1
I saw the following screen shot when i did the ping from secondary VM to primary VM

- IanBCommunication between the two virtuals looks to be working. My question was what happens if you ping the host from the VE, or the VE from the host ?
- Frank_N
When i did the ping from host to VE i get request time out:
User$ ping 172.16.1.200 PING 172.16.1.200 (172.16.1.200): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 Request timeout for icmp_seq 3 Request timeout for icmp_seq 4 Request timeout for icmp_seq 5
and from VE to host:
I got %100 packet loss
- IanBI was actually asking for the tcpdump output from eth0 on the BigIP at the same time as the ping from the host

- IanBThanks for the update. I suspect the problem lies with vmware, rather than BigIP, as your two VEs had no problem talking to each other.
