I have 6 physical interfaces, each with some logical interfaces configured. The interfaces are connected to a Cat which is trunking the correct vlans to the PIX. On every PIX interface I'm getting "nnn invalid VLAN ID errors, nnn native VLAN errors" messages where nnn is a number that is rapidly incrementing. Here's an example of how the PIX and Cat are configured: </P><P></P><P>Cat port 5/1: </P><P>clear trunk 5/1 1-1005 (clear trunked vlans) </P><P>set trunk 5/1 on dot1q 20,30,40 (trunk these vlans) </P><P>set vlan 5/1 20 (set vlan for this port) </P><P></P><P>PIX intf ethernet1: </P><P>interface ethernet1 100full </P><P>interface ethernet1 vlan20 physical </P><P>interface ethernet1 vlan30 logical </P><P>interface ethernet1 vlan40 logical </P><P></P><P>Any idea as to why I'm seeing these native vlan errors? </P><P></P><P>Thanks, </P><P>Rich</P> Fri, 21 Feb 2020 06:49:43 GMT https://community.cisco.com/t5/network-security/native-vlan-errors-on-pix-intf/m-p/207247#M616691 r.crist 2020-02-21T06:49:43Z Re: native vlan errors on PIX intf https://community.cisco.com/t5/network-security/native-vlan-errors-on-pix-intf/m-p/207248#M616692 <HTML><HEAD></HEAD><BODY><P>Figured it out on my own!</P><P></P><P>Rich</P></BODY></HTML> Tue, 01 Jul 2003 20:02:58 GMT https://community.cisco.com/t5/network-security/native-vlan-errors-on-pix-intf/m-p/207248#M616692 r.crist 2003-07-01T20:02:58Z
