Ring Number Mismatch
A frame was discarded for one of two reasons:
— In an explorer frame, the RIF length was larger than 2 and the ring number
of the HSTR port was not the last ring number in the RIF.
— In a non-explorer source-routed frame, the HSTR port ring number was
not in the RIF.
•
Duplicate Ring Number
A source-routed frame was discarded because it contained the HSTR port ring
number more than once. This could indicate a loop in the spanning tree.
•
Frame Too Large
The frame was larger than the maximum frame size configured for the virtual
port. Refer to the table of maximum frame sizes in the description of virtual-
port configuration.
•
Route Descriptor Too Large
An explorer frame had a RIF length that would exceed the configured
maximum hop count limit if more hops were added. The frame therefore was
forwarded only to the other ports in the same CRF as the receiving virtual port.
•
Filtered By Address Filter
A frame was discarded because of a MAC address filter.
•
Filtered By DSAP Filter
A frame was discarded because of a protocol (DSAP or protocol type) filter.
•
CRF Mismatch
A frame was discarded because the destination MAC address or destination
source-route hop was registered as local for the virtual port. That is, the frame
would have been forwarded to same port. This might be due to an error in the
configured 802.1Q VLAN ID for one or more VLANs.
•
Explorer Overflow
An explorer frame was discarded because the explorer throttle limit had been
exceeded.
•
Blocked Virtual Port
The virtual port was not in forwarding state. The blocked state may have been
permanent (because the spanning tree protocol detected multiple parallel
paths) or transient (during network topology changes).
