Getting pool info listing member host:port

Hi,

 

I am new to F5 and to this forum so I am not sure if this is right place to post this question.

 

 

What I am trying to do is to query F5 for a node and return me the pool that node belongs to. Since I wasn't able to find anything that returns this information, I decided to use

 

 

"tmsh show running-config ltm pool" command

 

 

This command returns me the information about the pools and the nodes in each pool. However, members are listed with their IP address and protocol (instead of port number). Is there a way to have the members being returned in 1.2.3.4:80 format instead of 1.2.3.4:http?

 

 

Thanks for your help.

    can u check Bigpipe.DisplayServiceNames db key? 

    [root@tulip:Active] config  b db Bigpipe.DisplayServiceNames
Bigpipe.DisplayServiceNames = true
[root@tulip:Active] config  b pool foo list
pool foo {
   members 10.10.70.110:http
}

[root@tulip:Active] config  b db Bigpipe.DisplayServiceNames false
[root@tulip:Active] config  b pool foo list
pool foo {
   members 10.10.70.110:80
}

    Thanks. This works.

     

     

    This seems to be a persistent change, though. Do you know if there is something similar that only affects the current session ?

     

     

    I would also be interested in finding a tmsh equivalent. Do you know if one can do this in tmsh ?

     

     

    Thanks for the help.

    Hi

     

     

    If you want your bigip.conf to list Port Numbers instead of the Service Name:

     

     

    Globally configuring the BIG-IP system to not translate service and protocol numbers to names when storing configuration objects in the bigip.conf file

     

     

    Log in to the BIG-IP command line.

     

    Type the following command:

     

     

    bigpipe cli service number

     

     

    Note: The service option is incorrectly described in the bigpipe cli man page. For more information, refer to SOL11301: Documentation Erratum: The bigpipe cli man page provides incorrect information for the service option.

     

    Save the configuration by typing the following command:

     

     

    bigpipe save

     

     

    Note: The bigip.conf file is now saved using service and protocol numbers rather than names.

     

     

     

    This is from SOL12251: Missing or ambiguous entries in the /etc/protocols or /etc/services files may cause configuration errors

     

     

    Hope this helps.

Do you know if there is something similar that only affects the current session ?bigpipe.displayservicenames db key will affect when displaying only (the config file will still use service name). the command Michael mentioned will make config file use service number instead.

    this is tmsh version. 

    root@sunflower(Active)(tmos) list sys db bigpipe.displayservicenames
sys db bigpipe.displayservicenames {
    value "true"
}
root@sunflower(Active)(tmos) modify sys db bigpipe.displayservicenames value false
root@sunflower(Active)(tmos) list sys db bigpipe.displayservicenames
sys db bigpipe.displayservicenames {
    value "false"
}

    Once you make the change in tmsh do you need to restart anything. I did this change through tmsh and it didn't change the pool configuration to show the ports instead of the service name.

     

     

    admin@sunflower(Active)(tmos) list sys db bigpipe.displayservicenames

     

    sys db bigpipe.displayservicenames {

     

    value "false"

     

     

    ltm pool sunflower {

     

    members {

     

    10.10.10.167:talon-disc {

     

    session monitor-enabled

     

    }

     

    10.10.10.169:talon-disc {

     

    session monitor-enabled

     

    }

     

    }

     

    monitor tcp
