Wireless (WiFi) MOS equivalent?
Hello all, Is there a WiFi equivalent to the VoIP MOS score? We are looking for a way to measure performance of a fairly large WiFi deployment. We have 8000+ access points (All Cisco). WE have the standard Cisco tools for managing the wireless network (ISE, Prime etc). But we are coming up short with a way to “score” the network. Does anyone have experience with this that might be able to help? How do large conferences “measure” wireless service quality etc? We are already doing end user surveys etc. We have “soft date”, we really need data points. —Jim
Cisco 12000 series routers and IOS XR.
Is anyone on the list running the Cisco 12000 Series routers with XR? We have a couple of these in our network and are having a few issues with them. Specifically the line cards will reboot for some unknown reason (12000-SIP-501). We recently replaced one of the cards and the new hardware (<6mo old) is doing the same thing. Anyone have issues with these routers? -- Jim Wininger
Re: Cisco 12000 series routers and IOS XR.
What release are you running? We are currently at 3.6.2 (as recommended by Cisco (our SE and some upper levels)).

Cisco 7600 (7609) as a core BGP router.
I have an opportuniy to put two 7609s into the core of my network. Currently we have 3 upstream providers, taking full BGP routes. (2 in one router and one in another). We have 17 BGP peers/customers (peering to each router), and adding about one new BGP peer every 2-3 months. It is a modest network by most standards. We are running OSPF and BGP between the existing routers. Not rocket science, nothing special (no MPLS, no VRF etc), very simple network. Does anyone have any recommendations on the 7600's as a core BGP router? Good or bad? Have they been a stable platform in a core/BGP environment? -- Jim Wininger
Re: Cisco 12000 series routers and IOS XR.
Neil, What release ox XR are you on? We had the 12000-SIP-501 in both 12ks but juet RMAed one of them and receive a 12000-SIP-601. The SPA-5X1Ge remain the same. What hardware are you running? If I may ask, what do you mean by "painful". Our experience with the 12000 (running ISO XR day one) has been quite an exercise in frustration.

Re: What Platform for a small ISP (was: Cisco 7600 (7609) as a core BGP router)
What do you consider a "small start-up ISP"? What kind of upstream connectivity are you considering (or at least falls under the category of small isp) bandwidht, bgp etc? On 7/22/09 9:39 AM, "R.

Subnet Size for BGP peers.
I have a question about the subnet size for BGP peers. Typically when we turn up a new BGP customer we turn them up on a /29 or a /30. That seems to be the "norm". We connect to many of our BGP peers with ethernet. It would be a simple matter to allocate a /24 for connectivity to the customer on a shared link. This would help save on some address space. My question is, is this in general good or bad idea? Have others been down this path and found that it was a bad idea? I can see some of the pothols on this path (BGP session hijacking, incorrectly configured customer routers etc). These issues could be at least partially mitigated. Are there larger issues when doing something like this or is it a practical idea? -- Jim Wininger -- Jim Wininger jbot...@gmail.com
