Interface IP address?

Hi,

 

 

This maybe basic query but how do I assign IP address to 1.1,etc. interfaces?

 

 

I've created VLAN with IP address of the local subnet and put that particular interface under that vlan but I still cannot ping the vlan IP address from that particular subnet.

 

 

The switch that the LTM connects to is a Cisco 3750G...

 

 

What gives?

 

 

Thanks

    Which VLAN IP are you refering to? Do you mean you can't ping the default gateway in the VLAn or you can't ping from your network into the self address of the LTM?

    VLAN Ip of the LTM... I can't ping out or into the LTM from an external host which is on same subnet as the LTM vlan.

     

     

    Interface 1.1 is connected to the switch...

     

     

     

    Running: BIG-IP 9.4.7 Build 320.1 Final

     

    Thanks

    Is the Self adress and VLAN HSRP on the same network? Is there a default route on the LTM pointing to VLAN HSRP address which you can get to from an external host upstream from your network?

    Where would I find VLAN HSRP? When setting up the vlan, I did not see that setting...

     

     

    Self IP (10.10.0.100) is assigned to vlan 1, which is assigned to the 1.1 interface, which is hooked up to the switch (10.10.0.x subnet).

     

     

    Thanks
