Re: Ethernet duplex problems

The wire is only 5ft long. It does not run by an AC line. It is a UTP cable. I did replace the cable twice, no change. Since this is a critical link I would rather not put a layer 2 switch and have an additional point of failure. There seems to be some sore of mismatch between the cisco and the MT w...

Ethernet duplex problems

The link between the cisco and the MT router is performing very badly. I am seeing many errors on the cisco. MT does not seem to have the capability to report errors as far as I can tell. See below how the interfaces are set up. Notice how MT reports full-duplex=no and the cisco reports full-duplex ...

Re: WanPMC and 3.22?

Looks like 3.13 has /interfaces wanpmc

I could not find support for the SBE T3 cards in 3.22

Is there no support for these cards anymore?

By the way.. where is the change log and where was this announced?

WanPMC and 3.22?

Is the SBE WanPMC or WanPCI (same thing) DS3 card supported in 3.22?

If not. what is the latest version that does support it and is it still in /interfaces sbe?

Re: MTU setting on wanpmc

The tech on the provider side says that MTU=4470 is standard with DS3 equipment. And that we will keep having low throughput until we fix this. I would like to stay with MT but will probably have to switch if not fixed. By the way, I left a message for ncomm (th esales people for SBEi) tech person. ...

Re: MTU setting on wanpmc

The router on the other side was set to 4470 for a good long time before we realized that I was not. Now we are both set to 1500 and it works. I don't understand why there is a limit of 1500 if the hardware can do more. Is the a bug or a bas assumption of the MT development team?

The other side of my link is a cisco. They want me to set the MTU on my wanpmc DS3 card to 4470. The max seems to be 1600 why is that?

Thank you all for your comments!

JJCinAZ, I set up a system with a double NAT and it seems to work fine.

I like Sten's solution as well, I will try it on the work bench. By "it", I mean that traffic from the outside will forward to 123.0.0.2, and 123.0.0.2 will be able to see 123.0.0.3.

So if you were to change:
/ int vlan add name=vlan2 vlan-id=2 interface=ether2 arp=proxy-arp 
To:
/ int vlan add name=vlan2 vlan-id=2 interface=ether2 arp=enabled
Would it still work?

Doing it right from the start, in my opinion, is to use a separate VLAN per customer and use IP subnetting. I like the vlans too, for many reasons. I am not using v8 yet on the canopy equipment, but I will look into that too. Might there be a way to use vlans which are separt L2 broadcast space, th...

You might actually not have to do proxy-arp since the kernel will reply arp for *any* ip on the router on *any* broadcast interface. In 2.9.x you need to add a small unofficial address subnet for each vlan and then route the public ip to the local address on the router. In 3.x you can route the hos...

Conclusion

I am unable to get bridged vlans to work!

Connection is sporadic and unreliable!

Clients can not talk to each other despite the fact the the vlans ARE bridged!


Anyone care to comment? MT developers?

I would like to emphasize here that the reason for the vlans is so that I can monitor/control bandwidth per customer. The reason for the bridge is so that I can have all my customers on the same subnet. I give my customers public IP addresses but would still like them to be assigned dynamically.

I have been playing around with a working experiment on the bench. And I am testing various functions.


- Clients can NOT ping each other. I would thin it should work. is this a bug?

- After a while the clients can't ping the bridge interface (sm). ->bug?

How about exporting to a text file, then using a text editor to search and replace, and finaly use the import command.

You might also need to remove the old IP numbers after the updates have been completed.

You can also use the set command to replace a value

Support for SBE t3 cards

I have an MT router with a DS-3 SBE card and would like to see more stats on the interface (i.e. bits in/out ) similar to what I get to see on the Ethernet interfaces.

Is this only a hope or will these fetures make it into one of the future releases on MT?

My guess is that now you will resolve DNS, but will not yet be able to ping external IP numbers.

If so, I think you need "masq" setup. I ran into the same problem but have not yet resolved the issue.
