Filters on Cisco 350 Workgroup bridge

Why the WGB 350 filters do not understand PPPoE session protocol ?

When i block protocol number 0x8864 (PPPoE session) nothing happens. Packets still forwarded by the workgrou pbridge. When i do protocol monitoring on my WGB it isn't show the 0x8864 protocol ... it only shows only 0x8863.

I think you got it mixed up, better block both the Ethertype.

For your reference, an Ethernet frame which is a PPPoE frame will contain one of two ethertypes:

0x8863 Ethertype = PPPoE control packet (handles the PPPoE session)

0x8864 Ethertype = PPPoE data packet (contains PPP packets)

Re: Filters on Cisco 350 Workgroup bridge

when i block only 0x8864 Ethertype on my Workgroup bridge the PPPoE session is still working. It must not work after the PPPoE negotioation is established.

The workgroup bridge protocol monitoring not shows the 0x8864 Ethertype packets forwarding throught it, when all filters are off.

Is it a firmware bug ?

where i can report this bug ?
