Configuration Assistance: Configure Email Alerts for HA Failover Events and Device Offline
We have a BIG-IP VE High Availability Pair deployed in Microsoft Azure. We need to configure the BIG-IP to automatically send an email notification to our Operations teams immediately when a Failover event occurs(When the unit goes from Active to Standby or Offline) Could you provide the recommended procedure for the configuration to trigger these email alerts?
FTP and one leg setup - why not working
Hi, I tried to do setup like that: VS in 192.168.1.1/24 network with IP 192.168.1.100 SNAT assigned 192.168.1.200 FTP server IP 192.168.1.110 Flow is then: C -> 192.168.1.100:21 <-> 192.168.1.200:high_port -> 192.168.1.110:21 Client connecting either passive or active is always refused, based on trace: Passive - client attempt to connect to VS 192.168.1.100: to create data connection - VS is almost immediately sending RST to SYN packet. Backend server is reporting 425 Can't open data connection for transfer of "/" Active - as soon as backend server tries to create connection from port 20 to port passed by BIG-IP in PORT command BIG-IP is not responding to SYN, after 2 repeated SYN BIG-IP is sending RST-ACK, and backend server is again sending 425 Can't open data connection for transfer of "/" over control connection Same VS when accessed from another VLAN is working without issue in both Passive and Active mode. Tested on both v11.2.0HF7 and 13.0.0HF2. Am I missing something important that prevents FTP in one leg configuration? Piotr
Active F5 device
We know we can configure LTM to be in Active/Standby or Active/Active mode. My questions are : 1 ) Anyone knows how LTM determine the Unit is going to be Active of its own when we connected to the network, what are the factors involved into it ? Is there any priority set for the UNIT by default ? 2) What are the processes, which can happen to the system when we do a Force Standy to make the Unit standby ? Let me know if you are confused, i can try rephrasing with some examples again -Maneesh
