PKTPROCESSING Messages
Error Message C4K_PKTPROCESSING-4-UNKNOWNBRIDGEORROUTE: Unable to determine whether
to route or bridge software-processed packet with source mac [mac-addr] ,
destination mac [mac-addr] , source IP [ip-addr] , destination IP [ip-addr]
Explanation
When a replicated packet is sent to the software by an output ACL, the hardware does
not indicate whether the packet needs to be bridged or routed.
When resources are exhausted or when the ACLs that are programmed in the hardware cannot
handle processing directly (such as ACLs matching TCP flags), the supervisor engine sends the
packets to the software for processing. If the software cannot determine whether to bridge or route,
the packet might be dropped. This drop indicates that the packet was directed to a Hot Standby
Routing Protocol (HSRP) router group MAC address.
Recommended Action This is an informational message only. No action is required.
Error Message C4K_PKTPROCESSING-4-UNKNOWNSOURCELOCATIONFORBRIDGE:Unable to
determine source host location of replicated software-processed packet with source
address [mac-addr] and destination address [mac-addr]
Explanation
When a replicated packet is sent by an output ACL to the software for processing, the
hardware does not indicate the ingress port or VLAN ID.
When resources are exhausted or when the ACLs that are programmed in the hardware cannot
handle processing directly (such as ACLs matching TCP flags), the supervisor engine sends the
packets to software for processing. Without the ingress port identifier, the supervisor engine might
forward the packet back out the port on which it was received, possibly creating network loops or
other problems. If the switch is unable to recognize the ingress port from other information, the
packet is dropped.
Recommended Action This is an informational message only. No action is required.
PKTPROCESSING-5
Error Message C4K_PKTPROCESSING-5-NOTAPPLYINGACL:Not applying [input/output] Acl
for packet [packet-info]
Explanation
The software is unable to determine the correct ACL entry that is indicated by the
hardware. The hardware-provided index of the ACL content-addressable memory (CAM) indicates
that the software needs to take the actions for the entry at that index. If the packet was queued in the
hardware before the software could process it, the index is out of date.
Recommended Action This is an informational message only. No action is required.
