Flexibility, agility, speed and scale of application deployment can be achieved by adopting cloud native architecture. Enterprise and Telecommunication service providers are deploying multi cluster applications in a Hybrid cloud environment. 3. (QoS), access control lists (ACLs), Layer-2/ Layer-3 switching, Virtual LAN (VLAN) stacking and IPv6. The port ACL (PACL) feature provides the ability to perform access control on specific Layer 2 ports. Numbered ACLs: When using the access-list <1-99|100-199> command to create or add ACEs to a numbered ACL, each new ACE you enter is added to the end of the current list. Hi, To create a VLAN-based ACL, an access list needs to be created just the way it is created for a port-based ACL (PACL). The IoT vlan is denied access to the Lan by a switch ACL. Wrote one switch ACL to permit plex users to plex servers. This implies routing at least, so you will have to change the host's address or net mask. permit host any.
