I've seen the tutorials where the devices are connected to the same switch, but what about adding another switch into the mix. Diagram: http://imgur.com/idZuVdL Is there any extra configuration required in order for PC to ping its default gateway (SVI on SW2) ?

yuriy-sokhan · ‎03-20-2013

Yes the topology is PC-----ACCESSPORT----SW1----TRUNK----SW2 PC is on SW1 - vlan 10 SVI/Default gateway for PC is on SW2.- vlan 20 IPS is on SW2 - trunk vlans allowed 10,20 I thought since the VLANs must be bridged in order for PC to reach SVI, this would force IPS to pick up the traffic as nothing else would respond to the ARP request. Could you please explain this a little more? SW1 doesn't have any SVIs and is layer 2 only. Am i supposed to only allow VLAN 10 over the trunk? Should VLAN 20 not exist on SW1?

Hello everyone, I have an issue with an 4255 IPS using an inline VLAN pair. Here's the rough sketch of the topology: SW1 port 1 access vlan 10 - PC (10.20.30.2/24) port 48 trunk to SW2 - all vlans allowed and forwarding SW2 port 48 trunk to SW1 - all vlans allowed and forwarding port 1 trunk allowed vlan 10,20 to IPS g0/1 configured in inline VLAN pair; assigned to sensor etc. SVI vlan 20 for network 10.20.30.1/24 (up/up) I'm unable to ping SVI from PC. Anyone have any suggestions? Running packet display on IPS interface I only see BPDUs hitting the interface. VTP is enabled but pruning is disabled. Both vlans exist on both switches. I'm only seeing ARP requests from SVI on the IPS, but no replies coming from the remote switch. Alternatively the PC is sending ARP requests to the SVI IP, but those aren't getting resolved, nor are they getting to the IPS interface.

Does anyone know if this guy has been fixed and what code supports it? This is concerning the ASA 5500 X series.

Unfortunately no, the MAP and the RAP were set as infrastructure only and did not serve wireless clients. I don't see how this would cause much of a performance hit since the backhaul link is over the 5Ghz radio.

It is possible that when I tried it, the new setting didnt stick. I've gotten the warning, went back and it was still normal. I didn't get the warning when changing e0 on the MAP though. I believe cisco documentation says the backhaul of the RAP will do pretty much whatever you need as is without any further configuration...pass tags etc. My code is: 7.2.103.0

Justin - thanks for the notes. I also ran into the PVID mismatches on the trunks, so it does seem like a glitch in the mesh code or a combination of a certain switch IOS and the mesh bridges. Currently I have both bridges up and trunking about 5 VLANs I had to manually add on the MAP and set its e0 as trunk. I disabled VLAN transparent bridging on the WLC as well. The RAP config is fairly straightforward with switchport set as trunk with native vlan 700 and RAP backhaul e0 always set as normal. Both MAP and RAP have ethernet bridging checkboxes enabled as well. So far everything looks good and I'm optimistic that it will work. I haven't had a chance to test it, as the site is 3 hours away from me, but should have confirmation later tonight. Thanks again.

The WLC won't let you set the backhaul interface (e0) as anything but normal. Which is good I suppose. I hope Cisco updates their documentation regarding mesh wireless bridging. Lots of holes and little bits of info spread throughout 3-4 different guides.

Thank you. I'm really curious what your notes look like, as I've been bashing my head against the wall on this for a good part of my day.

Justin, I have 2x 1552E bridges and I need to bridge (ethernet to ethernet) about 6 VLANs over to the other side. This is a point to point. Can you provide a little insight as to what configuration issues you've experienced and how you got it to work? I have both sides connected to switches with the respective switchports configured as trunks with native vlan 700. I guess I should add the WLC is a 5508 and running 7.2.103.0 Thanks.
