Hi All, We have a PIX 525 running 7.2(2) image with 4 Physical interfaces running a UR license. On one of the interface we have already created 4 sub-interfaces, each assigned to different vlans. This has been working fine. We created an additional sub-interface. Initialy we were unable to communicate with the additional sub-interface and other intarfaces were working fine. We were not able to even ping the ip address that was assigned to the sub-interface. Show interface command output would show that it is transmitting.
While this is situation, problem started affecting already working sub-interfaces also. We lost connectivity to 2 of the working sub-interfaces.
After rebooting the FW, all seemed to be working fine for 5 minutes (including the newly created sub-interface), but one of the already working sub-interface stopped responding after 5 - 10 mins. We were observing that the newly created sub-interface is working fine still.
We removed the newly created sub-interface from configurations and rebooted the FW again and found that it is working fine. So the problem looked to be with he newly created sub-interface.
As per the documentation, PIX 525 with UR can support upto 100 Vlans.
Are there any limitations on number of vlan per physical interface? If yes, what is the maximum no of vlans allowed / recommended?
