Viewing discarded frames from a port
1. Select a port on a Fabric OS device running 7.1.0 or later and select Monitor > Discarded
Frames.
The Discarded Frames dialog box displays.
2. Review the data for the discarded frames from the selected port.
•
Discarded Frame History for the Selected Product table — Summary of the discarded
frames for the selected port.

Count – Number of discarded frames logged in the frame log with the same
timestamp, Tx Port, Rx Port, SID, DID, SFID, and DFID. The maximum number of
duplicate frames stored for any 1 second timestamp is 20.

Date / Time – Timestamp when the frames were discarded.

Type – Type of discard. Valid values include timeout, du (destination unreachable),
and unroute (not routable).

Tx Port – Egress port where the frames were bound to exit the chassis. When a port
display as -1 (or -1/-1 on slot-based systems), this indicates an internal (backplane)
port. For the du and unroute types, the column displays “--” because there is no Tx
port value due to the discard type.

Rx Port – Ingress port where the frames entered the chassis. When a port displays as
-1 (or -1/-1 on slot-based systems), this indicates an internal (backplane) port.

Source ID – Source ID in hex PID format.

Source – Source name. If the device port is an HBA managed by the Management
application, the host name displays.

Source Port – Source port name.

Source Switch-Port – Source Switch_Name – Port_Name .

Source FID – Source fabric ID.

Source Fabric – Source fabric name.

Destination ID – Destination ID in hex PID format.

Destination – Destination name. If the device port is an HBA managed by the
Management application, the host name displays.

Destination Port – Destination port name.

Destination Switch-Port – Destination Switch_Name – Port_Name .

Destination FID – Destination fabric ID.

Destination Fabric – Destination fabric name.
The following label displays beneath the Discarded Frame History for the Selected Product
table: A value for TxPort or RxPort of -1 (-1/-1 for slot-based systems) indicates an internal port.
