SSG Drop-Vlan Counter??

Hi Everyone,

 

       I have a question about a strange counter I am seing on one of my ssg-5's.   This perticular SSG has been having connectivity issues with the Internet, the SSG periodacly looses connectivity (3-4 seconds).  After looking at the hardware counters to determine if there are any errors I noticed that the drop vlan counter was really high.  Does anyone know what this is?  I read the description in the help but it seems strange that this would happen on a public interface.

 

Heres is the shot of the counters.   Also below is the def of dropvlan

 

in no buffer 0

out no buffer 0

re xmt limit 0

in overrun 0

out underrun 0

drop vlan 1370208

in coll err 0

out coll err 0

out cs lost 0

in misc err 0

out misc err 0  

in dma err 0

out bs pak 0  

in crc err 0

out discard 0  

in align err 0

out defer 0  

in short frame 0

out heartbeat 0  

 

 drop vlan: Indicates the number of dropped packets because of missing VLAN tags, an undefined subinterface, or because VLAN trunking was not enabled when the security device was in Transparent mode.
