Hi all:


Good day, we are new to Huawei and currently deployed some AR 1200 routers in our CORE, we are getting the following messages for SNMP and also for NTP, I already have created an ACL and denied NTP and SNMP with below syntax but still getting following notices, appreciate if you someone can help to sort that out.

for NTP.

Dec 19 2016 07:49:41 AMT-BACKUP %NTP/4/PACKET_LENGTH_WRONG(l)[131]:The received NTP packet is longer than or shorter than a valid packet. (RcvLen=12)

while NTP service is already disabled.

for SNMP

Dec 19 2016 07:39:45 AMT-BACKUP %SNMP/5/SNMP_IP_LOCK(l)[129]:The IP address of request message was locked because authentication failed. (SourceIPType=1,SourceIP=185.35.62.53)


below is the ACL i configured and deployed as in inbound in my both incoming interfaces.


rule 5 deny udp source-port eq ntp destination-port eq ntp
rule 10 deny udp source-port eq ntp
rule 15 deny udp source-port eq snmp
rule 20 deny udp source-port eq snmptrap


Thank you in advance for help.


Kindest Regards,

rule 5 deny udp source-port eq ntp destination-port eq ntp
rule 10 deny udp source-port eq ntp
rule 15 deny udp source-port eq snmp
rule 20 deny udp source-port eq snmptrap

the ACL configure wrong, the traffic destination port is ntp but not the source port.

please modify the ACL as below:

acl number 3000
rule 5 deny udp destination-port eq ntp
rule 15 deny udp destination-port eq snmp
rule 20 deny udp destination-port eq snmptrap

then apply in the inbound interface

interface GigabitEthernet0/0/0
description AMT-PE
ip address 80.95.x.x 255.255.255.252
traffic-filter inbound acl 3000

Seems it should work, have you deployed on all the interfaces that SNMP or NTP packets may pass through?

I have 2 active interfaces one is Cellular and one is Gig, both have this ACL as an inbound.

interface GigabitEthernet0/0/0
description AMT-PE
ip address 80.95.x.x 255.255.255.252
traffic-filter inbound acl 3000

and here is Cell


interface Cellular2/0/0

traffic-filter inbound acl 3000


even I closed NTP service but still I am getting messages, ACL is right ?

Thanks in advance.

Kindest regards,
Uzair

one more thing sir, I have one Tunnel interface and one Loopback interface, Loopback cannot have ACL however on my Tunnel interface I just implemented it, I will update you accordingly as message was appearing after 4 to 6 hours distance.

Kindest Regards,
