Hallo! I found recently out that snort inline or the bridge are not forwarding any bpdu packets! Is this a known problem or a missconfiguration ? Roman Glebov |

what does your bridge configuration look like?

hmmmm you will not see bpdu's in snort-inline. What makes you think they are not being passed? Do you have stp enabled on the bridge?

i did a test . i have one cisco device before the bridge and second cisco device after the bridge. the first sends the bpdu packets all the time, which are never received by the second one after the bridge. my stp on the bridge is off because it should not participate but simple forward all of the traffik. > hmmmm you will not see bpdu's in snort-inline.

Yes, there are vlans and everything on that network. And linux bridge should be there completely transparent and forward every possible packet/protocol. It looks like it does not do it somehow. hmm Roman Glebov P.S What does trunking mean? > Are you trunking and using vlans? > > Regards, > > Will > > On 4/21/07, Roman Glebov <sl...@sl...> wrote: >> >> i did a test . i have one cisco device before the bridge >> and second cisco device after the bridge. >> >> the first sends the bpdu packets all the time, which are never received >> by >> the second one after the bridge. >> my stp on the bridge is off because it should not participate but simple >> forward all of the traffik. >> >> > hmmmm you will not see bpdu's in snort-inline.
