Junos OS

What is the maximum number of inet / inet6 firewall filters that juniper mx series supports?

Hugleo,

There is "NO" hard coded limit for firewall filters in MX Series and the usage is based on the number filter in use (binded to interfaces).

The memory for Filters is allocated from MPC/FPC PFE. The following command indicated the firewall filters per FPC.

The summary keyword is hidden:

#run show system resource-monitor summary

Slot # 1
     Client allowed   : Yes
     Service allowed  : Yes

     Client denied    : 0
     Service denied   : 0
     Heap memory used : 207534120       In % : 6

                 Filter memory        IFL memory        Expansion memory
      PFE #       used  |   %         used  |   %          used  |   %
          0   23190992     29       267792      0             0      0         <<<<<<<<<<<<<<<<
