68 Management ACL Commands In order to ensure the security of the switch management features, the administrator may elect to configure a management access control list. The Management Access Control and Administration List (ACAL) component is used to ensure that only known and trusted devices are allowed to remotely manage the switch via TCP/IP. Management ACLs are only configurable on IP (in-band) interfaces, not on the out-of-band interface or the serial port. When a Management ACAL is enabled, incoming TCP packets initiating a connection (TCP SYN) and all UDP packets will be filtered based on their source IP address and destination port. Additionally, other attributes such as incoming port (or port-channel) and VLAN ID can be used to determine if the traffic should be allowed to the management interface. When the component is disabled, incoming TCP/UDP packets are not filtered and are processed normally. There is also an option to restrict all the above packets from the network interface. This is done by specifying "console only" in the MACAL component. If this is enabled, the systems management interface is only accessible via the serial port. All TCP SYN packets and UDP packets are dropped except UDP packets sent to the DHCP Server or DHCP Client ports. Commands in this Chapter This chapter explains the following commands: deny (management) management access-class management access-list permit (management) show management access-class show management access-list Management ACL Commands 1523
