Hello folks, Is it possible to gather snmp statistics from a linux bridge using the Bridge-MIB [rfc 1493 or rfc 4188]? The difference between the two rfc's, I think, is the latter's ability to support SMIv2 syntax. I have started with extracting the MIB from the rfc's and generating dot1dbridge.c and .h files using mib2c. Then i realized that the .c and .h files so generated are just

This changes the message_age_timer calculation to use the BPDU's max age as opposed to the local bridge's max age. This is in accordance with section 8.6.2.3.2 Step 2 of the 802.1D-1998 sprecification. With the current implementation, when running with very large bridge diameters, convergance will not always occur even if a root bridge is configured to have a longer max age. Tested

Hello, I have first a question (and then may be a problem), that I have difficulties to understand and eventually to investigate. On each of my guests VM, I see constantly a RX dropped number increasing , Even if the VM does nothing ! ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.100.15 netmask 255.255.255.0 broadcast 192.168.100.255

Hi I'm looking for code that implements the 802.1d spanning tree. Do you have an idea where can I download this code?

Hi, I am a newbie working on tc tool, i want to know whether we have the following classifiers available (1) source MAC address. (2) destination MAC address. (3) IEEE 802.1D user priority. (4) Ethertype (IEEE 802.3, 1998 Length/Type Field). Can any one help me in finding the help for the above classifiers. Thanks in advance Krishna Chaitanya

Hi Krishna, 1) If you want to classify according to MAC address, you could use iptables to mark the packet (using MARK target), but just source MAC is available for now. 2) Usually tc just could classify by fields of IP layer and its sublayer, so I think classify by ethertype is unavailable. 3) VLAN tag belongs to MAC layer! I''m not sure how to QoS for VLAN, can anybody give some

Santiago, I appreciate your offer. I'm not really a kernel hacker, however I do know C and I would be willing to try if you point me in the right direction. Here is my first attempt using Debian running on an UltraSPARC: debian{root}:/root<512>strace -f -F -v brctl addbr br0 execve("/usr/sbin/brctl", ["brctl", "addbr", "br0"], [/* 16 vars */]) =

Hi, I am not able to access the local CIFS share using samba on unix machine. It is returning with Access Denied. Please see the attachment for more details.

dear all: I try to configure a bridge in my embedded linux. I had fininshed these operations below: 1) configure kernel, select the option "802.1d bridge" 2) compile bridge-utils 3) issue these commands: ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr vb brctl addif vb eth0 brctl addif vb eth1 ifconfig vb 192.168.110.24 up

Hi all, I have a bridging firewall running fine with kernel 2.4.31 (Slackware 10.1) and iptables 1.2.11 Yesterday I install the new kernel 2.6.14.3 and iptables 1.3.4 but the bridging firewall doesn't work anymore. Do I need to patch the kernel 2.6 as what I did it for kernel 2.4? Or what I have missed? Regards, ro0ot

Fixes message_age field update in config BPDUs. Also checks whether the BPDU message age has exceeded bridge max age before transmitting config BPDUs.

Hello, I've been using tinc v1.0 for the last few weeks in router mode - to great success. It's EXACTLY what I was looking for in a VPN at the time - most of the security of IPSEC with none of the interoperability issues. However, a few days ago, I got a VOIP phone that doesn't use IP without paying several thousand extra dollars on top of what we've already spent on the phone

Hi, I have 2 servers which are connected to a gateway machine. The gateway and one server are running Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet ports on the gateway which are connected to the servers are combined into a single ethernet bridge device. Ever since 2.6.16, I have noticed that I can no longer cross-mount the two servers' /home directories via

Hi, I'm a student in a trainning period and I have to implement a RSTP in a embedded Linux. I wonder if someone knows if it exists a version of bridge-utils who can made this or if it's possible to modify my actual version (bridge-utils-1.0.6) to do that and how ? Thanks in advance. PS : sorry for my english it's not my natural language ^^.
