Syslog messages
Explanation
Denial of Service (DoS) attack protection was
enabled for multi-device port authentication
on the specified <portnum>, and the
per-second rate of RADIUS authentication
attempts for the port exceeded the
configured limit. The device considers this to
be a DoS attack and disables the port.
The device has received more than the
specified maximum number of prefixes from
the neighbor, and the device is therefore
shutting down its BGP4 session with the
neighbor.
Indicates that a port on which you have
configured a lock-address filter received a
packet that was dropped because the
packet's source MAC address did not match
an address learned by the port before the
lock took effect.
The e<portnum> is the port number.
The <mac-address> is the MAC address that
was denied by the address lock.
Assuming that you configured the port to
learn only the addresses that have valid
access to the port, this message indicates a
security violation.
Indicates that a Simple Network Time
Protocol (SNTP) server did not respond to the
device's query for the current time.
The <ip-addr> indicates the IP address of the
SNTP server.
Indicates that the device received a packet
from another device on the network with an
IP address that is also configured on the
device.
The <ip-addr> is the duplicate IP address.
The <mac-addr> is the MAC address of the
device with the duplicate IP address.
The <portnum> is the Brocade port that
received the packet with the duplicate IP
address. The address is the packet's source
IP address.
