Fw-1351; Fw-1352 - Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Reference Manual

Probable Cause Indicates that the number of invalid signatures has risen above the high boundary.
Invalid-signature violations indicate that a packet with an invalid signature has been received from
the primary fabric configuration server (FCS). When the primary FCS downloads a new
configuration to the other switches in the fabric, the packet is signed using the private key of the
primary FCS. The receiving switch has to verify this signature with the public key of the primary FCS
switch. If verification fails, it rejects the packet. This counter keeps track of the number of packets
received with invalid signatures.

Message
<timestamp>, [FW-1351], <sequence-number>,, INFO, <system-name>, <Label>, is
between high and low boundaries(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Probable Cause Indicates that the number of invalid signatures has changed from a value outside of the acceptable
range to a value within the acceptable range. Invalid-signature violations indicate that a packet
with an invalid signature has been received from the primary fabric configuration server (FCS).
When the primary FCS downloads a new configuration to the other switches in the fabric, the
packet is signed using the private key of the primary FCS. The receiving switch has to verify this
signature with the public key of the primary FCS switch. If verification fails, it rejects the packet.
This counter keeps track of the number of packets received with invalid signatures.
Recommended No action is required.

FW-1352

Message
<timestamp>, [FW-1352], <sequence-number>,, INFO, <system-name>, <Label>, value
has changed(High=<High value>, Low=<Low value>). Current value is <Value> <Unit>.
Probable Cause Indicates that the number of invalid certificates has changed. This violation indicates that a packet
with an invalid certificate has been received from the primary fabric configuration server (FCS).
Before a new primary FCS switch sends any configuration data to any switch in the fabric, it first
sends its certificate to all the switches in the fabric. The receiving switch has to verify that the
sender is the primary FCS switch and its certificate is signed by the Root CA recognized by the
receiving switch. This counter keeps track of the number of packets received with invalid
certificates.
