Protection against attack in hardware
ServerIron ADX allows for protection against attack in hardware without impacting MP or BP CPU
utilization. Configure the server the drop-all-mgmt-access command to drop all traffic destined to a
specified management IP address.
The following command drops all traffic destined to the management IP address 10.45.16.104.
ServerIronADX(config)# server drop-all-mgmt-access 10.45.16.104
Syntax: [no] server drop-all-mgmt-access <destination ip>
NOTE
For a router, the destination IP address is the physical or ve interface IP address For a switch, the
destination IP address is the management IP address.
The server drop-all-mgmt-access feature when used in combination with the server
prioritize-mgmt-traffic feature allows you to prioritize valid traffic while blocking unwanted traffic
destined to the management IP address.
For example, with the following configuration, only ssh, telnet and http traffic destined to
management IP address 10.45.16.104 will be prioritized and all other traffic destined to
10.45.16.104 will be dropped.
ServerIronADX(config)#server prioritize-mgmt-traffic 1.1.1.1 255.255.255.0
10.45.16.104 6 22
ServerIronADX(config)#server prioritize-mgmt-traffic 1.1.1.1 255.255.255.0

Peak BP utilization with TRAP
Show CPU-utilization command enhancement
The show cpu-utilization command displays CPU utilization peaks since the system boot or the last
reset of counters (using the clear cpu utilization command).
The command, clear cpu-utilization, on both the MP and the BP is used to reset the counter.
