Could someone direct me or provide me with instructions on setting up twp PA-500's in an Active Active configuration?
Much appreciated and Thank You
Please see the link below on how to setup Active Active HA.
Hope this helps.
If I understood correctly, PA-500 supports A/A solution per documentation but not Jumbo Frames. would you help me understand how this will work?
In PA documents (https://www.paloaltonetworks.com/documentation/71/pan-os/pan-os/high-availability/configure-active-a...) it mentions under Step 19 that " Enable jumbo frames on firewalls other than PA-7000 Series firewalls.
Switch ports that connect the HA3 link must support jumbo frames to handle the overhead associated with the MAC-in-MAC encapsulation on the HA3 link. "
In the Admin guide of the version 7.1, page 228, step 19 says this:
####Enable jumbo frames on firewalls other than PA‐7000 Series firewalls. Switch ports that connect the HA3 link must support jumbo frames to handle the overhead associated with the MAC‐in‐MAC encapsulation on the HA3 link. The jumbo frame packet size on the firewall must match the setting on the switch######
With that being said,
1.Is A/A solution will work as expected on a pair of PA-500?
2. Are the packets going to have an overhead? If yes how much?
3.If there is any switch in between the two FWs, should be any consideration on the switch MTU settings?
4.If MTU is larger than 1500 which is the default for PA-500 then what will happen? Is the FW going to fragment the packets?
5.If the fragmentation going to happen, is there going to be any performance concern, or any kind of heart beat settings that needs to be considered on the FWs?
