how to find out where an old IP Adress is used

Hello,

a few months ago we changed the vlan for a management-IP Adress, now i observed on the firewall the F5 tries to connect to the old management IP, but I can't find the IP in Config.

On ihealth I searched the Log for the old IP and I found a lot of entries like

 

 

makeRestCall (external) {"protocol":"https:","slashes":true,"auth":null,"host":"192.168.2.70:443","port":"443","hostname":"192.168.2.70","hash":null,"search":null,"query":null,"pathname":"/mgmt/tm/asm/policies/9E4OvTih1_P4Vau7wFUGVg","path":"/mgmt/tm/asm/policies/9E4OvTih1_P4Vau7wFUGVg","href":"https://192.168.2.70:443/mgmt/tm/asm/policies/9E4OvTih1_P4Vau7wFUGVg"}

 

 

where 192.168.2.70 is the old MGMT IP.

other Logs:

 

 

POL-xxx (ASM-Policy) connect ECONNREFUSED 192.168.2.70:443

 

 

could you give me a hint, where to look for in Configuration?

Reason:

trying to find out, why sometimes there's a failover to secondary machine and losing connection to pool-members

thank you

Karl

    I created already a qkview and in Ihealth I found the Log-Entry.

    But I did not found the IP Adress in Config Explorer

    Have you done a cd into the /config directory and performed a grep on all files? Also consider creating a QKView, loading into F5 iHealth, and performing a search for the IP address.

      kgaigl Typically that command is used when upgrading HA pairs of BIG-IQs but that's good that it resolved your issue. This might be worth bringing to the attention of F5 to see if they have a bug related to this specifically.
