PKTPROCESSING Messages
Error Message C4K_PKTPROCESSING-4-INVALIDACLACTION:Unable to determine the ACL
action to take because we ran out of memory. Address: src [mac-addr] dst
[mac-addr]
Explanation
There is insufficient memory to create a list of actions to perform on the packet. As a
result, the packet was dropped.
Recommended Action This is an informational message only. No action is required.
Error Message C4K_PKTPROCESSING-4-INVALIDACLACTIONFORSPANPORT: Unable to determine
the ACL action to take because we ran out of memory. Address: src [mac-addr]
dst [mac-addr]
Explanation
There is insufficient memory to create a list of actions to perform on the packet. As a
result, the packet was dropped.
Recommended Action This is an informational message only. No action is required.
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.
