Duplicate packets after applying an ACL (SW 24.4.1.4)

zsh — Thu, 29 Oct 2020 23:41:17 GMT

It seems that we are experiencing duplicate packets after applying an ACL on X460-G2. When pinging from a Linux host, we are seeing duplicate responses. If we remove the ACL from both active and standby boxes issue goes away. There is a mirror-cpu deny any any at the bottom of the ACL but this ACL works on some other locations just fine so I doubt it’s an issue.

Has anyone experienced such issue? Any thoughts?

For the record, I also see these logs, which makes me think that there is an issue with VRRP but VRRP shows master and backup as these devices supposed to work. I don’t see like master/master.

<Warn:VRRP.Advert.Ign> Advert for VR on vlan XXXX vrid 3 ignored: number of VIPs in advert (1), expected (2)

Hi,

What does your ACL look like?

Thanks,

Would be nice if you would share the exact problem and/or solution in public and not only via private message.
