similar to: [Bridge] bridge problem when one interface is in blocking mode

Hello all, I would like to know if it is possible to have 2 bridge instances running - one for the internal network and the other for the external network. What I need to explain is that I need the internal bridge to go though the Linux Kernel and pass its packets to the external network bridge. I am also hopeful that the internal network bridge will not need an IP address as I am hoping to

Recently ran into a problem with the 2.6.18 kernel on Xscale arch when a br= idge, with multiple interfaces on it, is configured with a redundant loop. = All interfaces are left on forwarding and nexer switch to block when the lo= op is introduced. This was tested against a 2.6.16 kernel and the problem d= id not occur, interfaces forwared and blocked correctly. Any help would be = appreciated.

I saw some big mistakes, here's the correct version : -------------------------------------------------------------------- void br_send_config_bpdu(struct net_bridge_port *p, struct bpdu *bpdu) { unsigned char buf[42]; buf[0] = bpdu->bpdu_header.protocol[0]; //0x00 buf[1] = bpdu->bpdu_header.protocol[1]; //0x00 buf[2] = bpdu->bpdu_header.version; //0x02 buf[3] =

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

Hi, I have downloaded rstp from sourceforge and I get a segfaults when running the daemon. This is the line where the problem arises: TST(ifc->master->stp_up,); just at the beginning of function: void bridge_bpdu_rcv(int if_index, const unsigned char *data, int len) in file bridge_track.c -------------- next part -------------- An HTML attachment was scrubbed...

I have noticed a change in the linux bridge implementation between 2.1.15 and 2.1.17. Specifically, I do not think BPDU's (generated from another bridge) are passed across the bridge when STP is disabled. I think this relates to the LLC handling of BPDU's directly invoking br_bpdu_rcv. In 2.6.15, the br_handle_frame function would pass a BPDU to the br_handle_frame_finish function

Hi Rahul, If you're certain that your problem isn't as Stephen suggested, you might want to have a look at this: --- (From http://ebtables.sourceforge.net/brnf-faq.html <http://ebtables.sourceforge.net/brnf-faq.html> ) How do I let vlan-tagged traffic go through a vlan bridge port and the other traffic through a non-vlan bridge port? Suppose eth0 and eth0.15 are ports of br0.

Hi Sam, do you know if there is anything done about cbb(4)? I have many wireless adapters with ath(4), but only the one based on PCMCIA is making problems on FreeBSD. I cannot boot my notebook with the device inserted into the port, or it will render the system unusable (100% load on cbb(4)). And all I can see is the following: Jul 12 14:58:39 link kernel: ath0: ath_chan_set: unable to reset

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've got a very strange problem. Lately I've been setting up my linux servers for network (layer2) redundancy with a bridge interface containing two ethernet interfaces connecting to two switches. So far I didn't have any problems with it, but now a very strange thing happens with a new server I'm installing. The server is an ibm x346 having two onboard BCM5721 cards, the

When we create an L2 loop on a bridge in netns, we will see packets storm even if STP is enabled. # unshare -n # ip link add br0 type bridge # ip link add veth0 type veth peer name veth1 # ip link set veth0 master br0 up # ip link set veth1 master br0 up # ip link set br0 type bridge stp_state 1 # ip link set br0 up # sleep 30 # ip -s link show br0 2: br0:

Hi, I am trying to control bandwidths of the connections by using TC with HTB. But I want to implement Leaky Bucket on this structure so as to have a straight flow. Due to being new in this area, could anyone help me how I could do this? Does TC support leaky bucket? Best regards, Fatih Duzova

Hi, I am using netem to add loss and then adding another qdisc within netem according to the wiki. Then i want to change the netem drop probability without having to delete the qdisc and recreate it. I try it but I get invalid argument: thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1% thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp capacity 54Mbit

Hi, after some time without FreeBSD I installed 7.1 on an IBM Thinkpad T30 (with ZFS root on encrypted geli, works great). Config is: FreeBSD hasking.alashan.nongo 7.1-STABLE FreeBSD 7.1-STABLE #3: Thu Feb 5 21:10:45 CET 2009 root@hasking.alashan.nongo:/usr/obj/usr/src/sys/HASKING i386 I tried using my ath based D-Link DWL G650, which still seems to have some issues in regard to interrupt

I rebuilt my notebook that has the atheros card in it, and forgot to save all of my setup to get it working. I am using dkms and the madwifi rpms from rpmforge. My modprobe.conf has a line: alias wifi0 ath_pci I can ifconfig wifi0 up But the command: /usr/sbin/wpa_supplicant wpa_supplicant -dd -D madwifi -i wifi0 -c /etc/wpa_supplicant/wpa_supplicant.conf fails. Now some of my old

I seem to be able to lock my machine by going into wpa_cli and asking it to 'reassoc'. The reason for question mark after "hard" is that debug information (caused by wlandebug and athdebug) is being printed on the console. The only way to get machine's attention is to hold power button for 8 seconds. Note: manual reassociation is just the handy way to reproduce the problem

So, with the updated HAL, I'm now able to negotiate an IP address via DHCP over the WLAN. Huzzah! But I've got two questions (now that I can use the card): ath(4) doesn't contain a list of media nor mediaopt settings that can be used. Some are detailed down in EXAMPLES, but there's no comprehensive list. (As well, and this is minor, the speeds are explicitly listed for 802.11a

Good morning, i have an Xanto S1000 USV the Manufactor is ONLINE USV-Systeme AG. I tried all the buildin drivers, also the driver for the driver for the Generic UPS, nothing worked for this UPS so now my question has anyone else this UPS and functional driver? Thanks and Greets Dennis
