30.5 CPU Protection Configuration

Use this screen to limit the maximum number of control packets (ARP, BPDU and/or IGMP) that the
Switch can receive or transmit on a port. Click the Click Here link next to CPU protection in the
Advanced Application > Errdisable screen to display the screen as shown.
Note: After you configure this screen, make sure you also enable error detection for the
specific control packets in the Advanced Application > Errdisable > Errdisable
Detect screen.
Chapter 30 Error Disable
DESCRIPTION
Enter the number of the port(s) (separated by a comma) on which you want to reset
inactive-reason status.
Select the cause of inactive-reason mode you want to reset here.
Press to reset the specified port(s) to handle ARP, BPDU or IGMP packets instead of ignoring
them, if the port(s) is in inactive-reason mode.
This is the number of the port on which you want to configure Errdisable Status.
This refers to the cause of Errdisable Detect or Errdisable Recovery on the Switch.
This field displays whether ARP, BPDU, IGMP and LOOP GUARD on the port is being detected
or not.
This field shows the mode of the cause.
• inactive-port - The Switch disables the port on which the control packets are received.
• inactive-reason - The Switch drops all the specified control packets (such as BPDU) on
the port.
• rate-limitation - The Switch drops the additional control packets the port(s) has to
handle in every one second.
This field displays how many control packets this port can receive or transmit per second. It
can be adjusted in CPU Protection. 0 means no rate limit.
This field displays the errdisable status
• Forwarding: The Switch is forwarding packets. Rate-limitation mode is always in
Forwarding status.
• Err-disable: The Switch disables the port on which the control packets are received
(inactive-port) or drops specified control packets on the port (inactive-reason)
This field displays the time (seconds) left before the port(s) becomes active of Errdisable
Recovery.
This field displays the total packet number dropped by this port where the packet rate
exceeds the rate of mode rate-limitation.
