icmp to the management port

Hi fairly new to BIG IP and I have this minor issue.

 

 

BIG-IP 9.4.6

 

 

We require monitoring of our management port via snmp (works great) and icmp (only works when the icmp source is located in the same subnet as the management port).

 

 

I can't understand why this would be the case, and can't find anywhere to change this in the GUI.

 

 

Help please

    most likely this is due to the lack of a management route to your source system. Mgmt routes are handled only at the command line, which can be accessed from the GUI by going to System->Console, then entering the appropriate mgmt route (bigpipe is already supplied for you in the GUI console, at the command line you will need to add it)

     

     

    mgmt route / gateway

    Hi thanks,

     

     

    Originally we had this:

     

     

    [root@DC2-F5-01:Active] config bigpipe mgmt route

     

    MGMT ROUTE default inet

     

    | GATEWAY 10.131.7.254 MTU 0

     

     

    So I added a route for the local subnet:

     

     

    [root@DC2-F5-01:Active] config bigpipe mgmt route

     

    MGMT ROUTE 10.131.7.0/24

     

    | GATEWAY 10.131.7.254 MTU 0

     

    MGMT ROUTE default inet

     

    | GATEWAY 10.131.7.254 MTU 0

     

    [root@DC2-F5-01:Active] config

     

     

    Now I am very confused as I still cannot ping the management port from anywhere but the local subnet though??

    So I added a route to the ICMP source subnet:

     

     

    [root@DC2-F5-01:Active] config bigpipe mgmt route

     

    MGMT ROUTE 10.135.7.0/24

     

    | GATEWAY 10.131.7.254 MTU 0

     

    MGMT ROUTE default inet

     

    | GATEWAY 10.131.7.254 MTU 0

     

    [root@DC2-F5-01:Active] config

     

     

    and that worked!
