Thanks for the quick response Scott. I do want the traffic local to the controller so I can take advantage of some of the AVC features, my understanding is that AVC is only available to WLANs/APs in local mode. Just a couple clarification questions: To clarify an interface group assigned to a WLAN would potentially put two clients attached to the same SSID on the same AP in different subnets/VLANs, correct? So the jist of the configuration outlined above should accomplish what I'm after (assuming interface groups aren't implemented)? Thanks again.

I'm having a rough time getting PI 1.2 to act as a trap receiver. I'm working with a 3560E running 12.2(55)SE6, according to the PI 1.2 supported device list the device and code version are supported. It appears that I am unable to receive anything but 'config' traps from this switch in PI for some reason. I have two trap receivers setup, one going to my laptop and the other to the PI server. My laptop receives errdisabled/linkup/linkdown traps as expected and the switch indicates it has sent traps to both my laptop and the PI server yet nothing is displayed under "Events" or "Alarms" in PI. The ONLY events that are displayed in prime by the switch are informational "configuration management events". Is there some additional configuration I need to do on the Prime side to get additional traps to display under events/alarms? Any help would be greatly appreciated.

So your "outside" interface has received an address via DHCP? Please post your current ACLs. Sent from Cisco Technical Support iPhone App

I think you need to add "permit udp any any eq bootpc" to the top of ACL 112, otherwise your 'WAN' interface isn't going to get a DHCP address. ACL112 should look like this: access-list 112 permit udp any any eq bootpc access-list 112 permit icmp any any access-list 112 deny ip any any log Once added, confirm Fa4 picks up an address via "sh int fa 4" or "sh ip int brief". If this solves it, Henrik deserves credit as he pointed this out in his original post. HTH Mitch

That is still an insane amount of packet loss. Can you temporarily connect the H3C again and see if the problem goes away? I've never worked with an H3C before -- would it be possible to check the MTU on it's 'WAN' interface? Also, are you seeing that kind of packet loss just pinging the gateway?

Doesn't look like an ARP issue. Looks like packet loss to me, can you verify the cable is good? Does the problem persist if you plug a machine in, replacing the router? Sent from Cisco Technical Support iPhone App

Are you using a dynamic crypto map on the HQ side? Seems odd that the remote router would get a new address without tearing the tunnel down or the tunnel timing out. You might look at changing the timeout period, as previously mentioned or look into the use of keep alives. HTH Sent from Cisco Technical Support iPhone App

I still don't think that setting the root bridge to something other than the active HSRP switch will provide any benefit, regardless of which switch is the root, it's failure will result in non optimal conditions regardless of where its located in the network.

Can you site your sources on poor RPVST convergence times? The only information I found regarding the convergence of RPVST after a root bridge failure was regarding mis-configurations of RPVST. This might help with understanding why there shouldn't be poor convergence times: http://www.cisco.com/en/US/tech/tk389/tk621/technologies_white_paper09186a0080094cfa.shtml My concern with setting the standby HSRP switch as the root is that typically in a full mesh environment with either a dedicated core or collapsed core is that this will cause all traffic to traverse the link between the standby and active HSRP switches, as links from other switches to the active should be blocking. This may produce a bottleneck to the active HSRP device. This may or may not be true for your particular topology. Sent from Cisco Technical Support iPhone App

I forget the specific context but you can add statements based on line numbers, I believe it is: "access-list line <#> permit...." You can view current line numbers in an ACL with "sh access-list ". HTH Mitch Sent from Cisco Technical Support iPhone App

With the exception of trunk ports is your environment mostly one device per port? If you aren't using unmanaged or work group switches and you answered yes to the question above you can use the CAM table to see which ports have learned more than one MAC (assuming the hubs have multiple devices connected to them).

My bet is the trace route is "failing" because there isn't actually a hop from switch A to B, they are in the same subnet, though different VLANs. Traffic destined between switches isn't being routed, it's being switched. The other option may be that the switches are missing default gateways.

A couple issues....the crypto ACL posted doesn't match the one in the crypto map, also the peer doesn't match the provided diagram, I may be misremembering but I don't recall seeing PFS configured on the 2800. I'll review again in the morning. Sent from Cisco Technical Support iPhone App
