When running show config effective on an MD node I see the config
interface port-channel 0
switchport mode trunk
switchport trunk allowed vlan 1-4094
switchport trunk native vlan 1
trusted
ip access-group in block_mdns
trusted vlan 1-4094
where block_mdns is defined elsewhere. This is. present on both MD boxes in our cluster.
Looking at the MD configurations at via the GUI, although an inbound / outbound policy has been defined, it doesn't say what the inbound inbound one is just that there isn't an outbound one. You can remove the policy via the GUI by selecting no policy and you end up with
interface port-channel 0
switchport mode trunk
switchport trunk allowed vlan 1-4094
switchport trunk native vlan 1
trusted
trusted vlan 1-4094
.... so how do you revert it back ?
From the GUI you can enable inbound/outbound but theres not an block_mdns option.
From the CLI, when MDconnected to the MD controller you wish to revert, you're told that you need to do this from the MM
On the MM, even if you cd to the MD box, i suspect you're still editing the MM config ...
So how do you add the block_mdns entry back into the controller?
