Messages 100001 to 199006
This section contains messages from 100001 to 199006.
100001
Error Message %ACE-2-100001: EOL function chars from library chars exited due to Signal decExplanation An error occured in the CLI end of line (EOL) function.
Recommended Action No action is required.
106021
Error Message %ACE-1-106021: Deny protocol reverse path check from source_address to dest_address on interface interface_nameExplanation Someone is attempting to spoof an IP address on an inbound connection. Unicast reverse path forwarding (RPF), also known as reverse route lookup, detected a packet that does not have a source address represented by a route and assumes that it is part of an attack on the ACE.
This message appears when you have enabled Unicast RPF with the ip verify reverse-path command (see the Cisco Application Control Engine Module Security Configuration Guide. Reverse path forwarding works on packets that are sent to an interface. If you configure this command on the outside, then the ACE checks packets arriving from the outside.
The ACE looks up a route based on the source address. If an entry is not found and a route is not defined, then this system log message appears and the connection is discarded.
If a route is defined, the ACE checks which interface to which it corresponds. If the packet arrived on another interface, it is either a spoof or there is an asymmetric routing environment that has more than one path to a destination. The ACE does not support asymmetric routing.
If the ACE is configured on an internal interface, it checks static route command statements or RIP, and if the source address is not found, then an internal user is spoofing their address.
Recommended Action Even though someone is attempting to spoof an IP address on an inbound connection, if this feature is enabled no user action is required. The ACE repels the attack.
106023
Error Message %ACE-4-106023: Deny protocol number | name src incoming-interface:src-ip dst outgoing-interface:dst-ip by access-group "acl-name"Explanation An IP packet was denied by the ACL. This message displays even if you do not have the log option enabled for an ACL. If a packet hits an input ACL, the outgoing interface will not be known. In this case, the ACE prints the outgoing interface as undetermined. The source IP and destination IP addresses are the unmapped and mapped addresses for the input and output ACLs, respectively, when used with NAT.
Recommended Action If messages persist from the same source address, messages may indicate a foot-printing or port-scanning attempt. Contact the remote host administrators.
106028
Error Message %ACE-1-106028: WARNING: Access rule memory exhausted while processing Access-group. Incomplete rules are currently applied on interface interface-name. Manual roll back to a previous access rule configuration on this interface is needed.Explanation The access control list (ACL) compilation process has run out of memory, which does not allow new ACL entries to be applied to the specified interface. The ACL configuration downloaded in hardware for that interface may not be in a known state because of this failure.
Recommended Action Remove some ACL entries to free up memory for the desired configuration. The affected interface needs to be removed and recreated to recover to a known state.
111008
Error Message %ACE-5-111008: User root executed the string commandExplanation This message is informational. The user entered a command that modified the configuration.
Recommended Action None required.
111009
Error Message %ACE-7-111009: User user executed cmd:stringExplanation This message is informational. The user entered a command that does not modify the configuration.
Recommended Action None required.
199006
Error Message %ACE-2-199006 : Orderly reload started at when by whom. Reload reason: reasonExplanation This message logs a reload record of the ACE and the reason for the reload.
The reason variable describes why the reload occurred. Possible reasons are as follows:
•
reload command
•
•
The when variable specifies the time at which the orderly reload operation begins.
The whom variable specifies the name of the user who entered the reload command. If the reload is caused by other reasons, System is specified.
Recommended Action None required.

322001
Error Message %ACE-3-322001: Deny MAC address MAC_address, possible spoof attempt on interface interfaceExplanation The ACE received a packet from the offending MAC address on the specified interface, but the source MAC address in the packet is statically bound to another interface in your configuration. This situation can be caused by either a MAC-spoofing attack or a misconfiguration.
Recommended Action Check the configuration and take appropriate action by either finding the offending host or modifying the configuration.
322002
Error Message %ACE-3-322002: ARP inspection check failed for arp {request|response} received from host MAC_address on interface interface. This host is advertising MAC Address MAC_address_1 for IP Address IP_address, which is {statically|dynamically} bound to MAC Address MAC_address_2.Explanation If ARP inspection is enabled, the ACE checks whether a new ARP entry advertised in the packet conforms to the statically configured or dynamically learned IP-MAC address binding before forwarding ARP packets. If this check fails, the ACE drops the ARP packet and generates this message. This situation can be caused by either ARP spoofing attacks in the network or an invalid configuration (IP-MAC binding).
Recommended Action If the cause is an ARP spoofing attack, deny the host by using an ACL. If the cause is an invalid configuration, correct the binding (see the Cisco Application Control Engine Module Routing and Bridging Configuration Guide for details).
322003
Error Message %ACE-3-322003: ARP inspection check failed for arp {request|response} received from host MAC_address on interface interface. This host is advertising MAC Address MAC_address_1 for IP Address IP_address, which is not bound to any MAC Address.Explanation If ARP inspection is enabled, the ACE checks whether a new ARP entry advertised in the packet conforms to the statically configured IP-MAC address binding before forwarding ARP packets. If this check fails, the ACE drops the ARP packet and generates this message. This situation may be caused by either ARP spoofing attacks in the network or an invalid configuration (IP-MAC binding).
Recommended Action If the cause is an attack, deny the host by using an ACL. If the cause is an invalid configuration, correct the binding (see the Cisco Application Control Engine Module Routing and Bridging Configuration Guide for details).

456068
Error Message %ACE-3-456068: Unable to send base page because cookie not found for request urlExplanation The base file was not sent because an expected cookie was not found; the base file application acceleration server cookie has been dropped. The application acceleration server inserts JavaScript code into the page returned to a user on the first visit to a site. When executed by the client browser, this code creates the application acceleration server cookie with a randomly generated 128-bit user ID. Client browsers that do not support JavaScript will simply ignore the script, and no application acceleration server cookie will be created. Upon a second request from the client, the application acceleration server looks for the application acceleration server cookie to verify client JavaScript and cookie support. If the application acceleration server sees the application acceleration server cookie, it assumes that the client supports JavaScript. If it does not see the application acceleration server cookie, it assumes that the client does not support JavaScript, or cookies (or that this may be the first request from this client), and it will not provide condensation for this user's requests.
Recommended Action Base file requests should always be accompanied by the basefile application acceleration server cookie. Ensure that any intervening nodes do not remove this cookie from the base file request.
