Are you getting VLAN-tagged packets on a non-tagged interface?  Or
vice-versa?

Hi all,

We have some problems on our core in amsterdam with SNMP see the following
examples of a monitor on gigabit ethernet 0/0/0

And every two seconds it gives away zero and then maximum.

On our foundry bigiron switch 8000 their are no port errors and the snmp
goes well.

Also internal vlan's on the same interface (ge-0/0/0) are correct. But when
we monitor the interface
as total traffic, it flushes all stats and returns zero or other errors.

We run OSPF and BGP with about 19 vlan's defined on this interface.

The board is a 4 port gigabit ethernet board and it gives the same stats on
every interface from
ge-0/0/0 to ge-0/3/0 vlan's are correct but the interface itself for total
traffic is broken.
