Brocade VDX 6720 Blocking IPs Until Reboot

[Adam_Schappell]

Hey Everyone,

I keep having this issues with our Brocade switch to where it blocks an IP until I reboot the switch. How can I see what is causing this or allow it without reloading the switch.

Also when I reboot the machine connected to the switch, that is when it gets blocked. Then I reboot the switch and it comes back up.

Hi Adam,

We would need a 'copy support' collected from the 6720 during the problem state, then another 'copy support' after you reboot it to see why that IP is being blocked.

In general, if the VDX should be on 4.1.3d which contains all the latest fixes. If it's not on 4.1.3d firmware yet, I highly recommend upgrading to it, then verify if you still have the issue.

If you still do, then please collect the data requested from above during the problem and after.
