SECE/4/ARP_PACKET_BLOCK

Message

SECE/4/ARP_PACKET_BLOCK: ARP packets were blocked. (SourceInterface=[STRING], BlockTime=[ULONG]seconds)

Description

All the packets on the interface are blocked at the time specified by block time.

Parameters

Parameter Name Parameter Meaning
SourceInterface Indicates the inbound interface of ARP packets.
BlockTime Indicates the time ARP packets are blocked.

Possible Causes

After rate limiting on ARP packets is configured on an interface, if the rate of ARP packets exceeds the rate limit, the system delivers an ACL to discard ARP packets on the interface.

Procedure

  • If user services are not affected, the alarm does not need to be handled.
  • If the user services are intermittently disconnected, run the arp anti-attack rate-limit packet packet-number command in the interface view to adjust the ARP rate limit. Adjusting the rate limit may affect CPU usage. You are advised to contact technical support personnel.

SECE/4/ARPMISS

Message

SECE/4/ARPMISS: Attack occurred. (AttackType=Arp Miss Attack, SourceInterface=[STRING], SourceIP=[STRING], AttackPackets=[ULONG] packets per second)

Description

The rate exceeds the global ARP Miss rate limit.

Parameters

Parameter Name Parameter Meaning

SourceInterface

Indicates the name of an interface.

SourceIP

Indicates the source IP address of attack packets.

AttackPackets

Indicates the rate of attack packets, in pps.

Possible Causes

If a host sends a large number of IP packets with unresolvable destination IP addresses to attack a device (the device has a route to the destination IP address of a packet but has no ARP entry matching the next hop of the route), the device generates a large number of ARP Miss messages. When the rate of ARP Miss messages exceeds the global ARP Miss rate limit, the device generates the alarm.

Procedure

  1. Run the reset cpu-defend statistics command to clear statistics on the ARP Miss messages sent to the CPU.
  2. Wait for 1 minute, and run the display cpu-defend statistics all command to check the number of ARP Miss messages sent to the CPU within 1 minute. Check whether a large number of packets are discarded:

    • If so, go to step 3.

    • If not, verify that the network is secure and run the info-center source SECE channel 4 log state off command to disable the device from sending SECE log information.

  3. Locate the attack source based on the IP address in the log information.

    Check whether the attacker is infected with viruses.

    • If so, you are advised to remove viruses from the user host. You can also add the address of the user to the blacklist or configure a blackhole MAC address entry to discard ARP request packets sent by the attacker.

    • If not, go to step 4.

  4. Run the display arp anti-attack configuration arpmiss-rate-limit command to check global configuration of source-based ARP-Miss suppression.
  5. Run the arp-miss speed-limit source-ip [ ip-address ] maximum 0 command to configure the device not to limit the rate of ARP Miss messages based on source the IP address.
  6. If the log is frequently generated, collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.

SECE/3/IPSG_RESOURCE_LACK: Resource for IP Source Guard in slot [STRING] is not enough. (Vlan=[ULONG])

Description

The ACL resources corresponding to IPSG are insufficient, so delivery of ACL resources fails.

Parameters

Parameter Name Parameter Meaning

slot

Specifies the slot ID.

Vlan

Specifies a VLAN ID.

Possible Causes

When IPSG is enabled in the VLAN view, if the ACL resources are insufficient, the device will generate this log.

Procedure

  2. Run the display current-configuration command to check the current configuration on the switch.
  3. Check the services that occupy ACL resources based on ACL resource information and the current configuration as follows, and delete unnecessary services to release ACL resources.

    • Check whether NAC, IPSG, MQC, and ACL-based simplified traffic policy services that occupy a large amount of ACL resources exist on the switch.
    • Check the services that occupy ACL resources based on fields in the ACL resource information. For example, MQC, ACL-based simplified traffic policy, SVF, MPLS, and BFD for VPLS services occupy UDF ACL resources. If a large amount of UDF ACL resources are occupied, check these services first.

  4. If the fault persists, collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.

A lot of attack packets from the corresponding IP address were received on the interface.

Procedure

  1. Run the display auto-defend attack-source command to check whether the user attack packets exist.
  2. If so, run the auto-defend action deny [ timer time-length ] command to discard the attack packets.
  3. If the fault persists, collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.

SECE/4/STICKY_MAC_CONFLICT

Message

SECE/4/STICKY_MAC_CONFLICT: The MAC address entry of another type already exists. (MAC=[OCTET])

Description

The device failed to generate a snooping MAC entry after the user-bind ip sticky-mac command was run.

Parameters

Parameter Name Parameter Meaning
MAC MAC address that conflicts with the MAC address in the snooping MAC entry.

Possible Causes

A static MAC address on the device contains the same MAC address as that in the snooping MAC entry and its type is different from that of the snooping MAC entry.

Procedure

  1. The switch already has static MAC entries. The static MAC entries are not updated dynamically. Therefore, snooping MAC entries do not need to be generated based on the binding table. This log is informational only, and no action is required.
