Cause and Resolution
The CSS detects that it has received an
invalid ARP packet. The following
messages can appear in the log to
clarify why the CSS logs the receipt of
an invalid ARP packet.
IPV4-4: ffff53ff01ff ff0077fa6503
0806
IPV4-4: HW type: 0x0000
type: 0x0000
IPV4-4: HLEN 0x00 PLEN 0x00
OPTPA-TSI-CSS1# 0x0000
IPV4-4: Sender HA 000000000000
IPV4-4: Sender IP 0.0.0.0
IPV4-4: Target HA 000000000000
IPV4-4: Target IP 0.0.0.0
The first line in the log message
identifies the destination MAC address
of the packet, the source address of the
packet, and the type of IP packet. In the
example above, the destination MAC
address is ff-ff-53-ff-01-ff and the
source MAC address is
ff-00-77-e7-65-03. In addition, 0806
equals ETHERTYPE_ARP.
The second line in the message
identifies the hardware type and
protocol type. In this example, the CSS
logs the messages because both the
hardware type and protocol type are
0000. The CSS views this value as an
indication of an invalid packet.
