Modify BGP AS Path
Dear all Hi Is there any way to change AS Path "no prepend". I am in a situation needs some Prifixes to look like it comes from my ASN ( not private ASN). Thanks
POE bump-in-the-wire conversion
Perhaps someone from this august list can offer a clue here. Have: Cisco 3524-PWR (paleo-POE, pre-802.3af Cisco standard). It runs the 7960Gs great. Have: Wireless AP stuff that wants 12v on the unused pairs for passive POE. 48v will let the magic smoke out. Might buy: phone that does 802.3af Want to run these with the 3524-PWR. I can't imagine that nobody makes a bump-in-the-wire converter for this application, but haven't been able to find anything other than 802.3af to the passive POE use case. Anyone got a pointer for me? Thanks, -r
Re: Modify BGP AS Path
Well, you could always aggregate them (even same prefix) in your own ASN and that would generate a fresh version of the route...

Re: POE bump-in-the-wire conversion
We have some Aastra 9480i phones that are 802.3 af running off of a cisco 3550 that are Pre-Standard power. http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps646/prod_qas09186a00800913d3.html "Q. Does the Cisco Catalyst 3550-24 PWR Switch support the 802.3af inline power standard? A. No, this switch supports Cisco Pre-Standard Power over Ethernet. The Catalyst 3750 Series and Catalyst 3560 Series support the Cisco Pre-Standard Power over Ethernet and IEEE 802.3af Power over Ethernet." I used the command power inline delay shutdown 20 initial 100 on the ports connected to the phones and it seems to be working just fine. It may just be a lucky break for us but something worth trying? -=Tom On Fri, 31 Dec 2010 09:00:40 -0600, Robert E. Seastrom wrote: Perhaps someone from this august list can offer a clue here.

Re: POE bump-in-the-wire conversion
I was aware of this device (being a big Ubiquiti fan), but have yet to find anyone who has direct experience with using them on a 3524-PWR. Have you actually tried this (on a 3524-PWR, not a 3550 or anything later-but-pre-standard)? The equipment will be quite happy with 16v... -r Philip Dorr writes: > The Ubuquti Instant 802.3af seems to do what you want (as long as the > equipment can handle 16v) > > http://ubnt.com/8023af > http://ubnt.com/downloads/instant8023af.pdf > > On Fri, Dec 31, 2010 at 9:00 AM, Robert E.

Re: Modify BGP AS Path
Hi all Thanks Scott, aggregate with suppress-map. I managed to solve my problem. Infact, I have customers get to my POPs via MPLS VPN L3, through other ISP, this why I have got to remove this ISP ASN from my customers AS path.

They're a standard 802.3af device, and they just step-down to 16V @ 0.8A (max) though they seemed to get a bit warm at 0.8A but worked fine, haven't had one die yet. To the switch they are a 100% 802.3af device so may not work with the 3524-PWR. I've not tried any 802.3af devices with the 3524-PWR, I have gone the other way (802.3af injector/switch with pre-standard devices that accepted 48V) -- You might be better off upgrading to an 802.3af switch or using a seperate 802.3af power injector device/devices, enterasys for example makes a 20 port injector (last I checked) among others. Most almost all 802.3af units will also do a Cisco compatible 'pre standard' mode for the older 7900 series phones that aren't 802.3af. Pre standard cisco POE is limited to about 10W, as IIRC, it uses only one pair (pins 1,2) for DC power, the device has a low pass filter to get rid of the DC component for the ethernet receiver hardware. 802.3af doesn't define which wires/pins to use but generally will use the unused pairs, 4,5 and 7,8 for DC+ and DC-, unless it's gig-e, then it uses 1,2 and 3,6 (again this is just my experience with some Netgear and HP gear and doesn't necessarily represent anything else). The use of pins 1,2 for power is possibly also why you don't see pre-standard to 802.3af because there's far less available power, AND, you'd have to build a low pass filter and possibly regenerate the Ethernet signal to make it work too. Combine that with cheap 802.3af injectors (either rack/multiport units, or single units) there's not a lot of incentive for hardware manufacturers to build such devices either. > > -r > > Philip Dorr writes: > >> The Ubuquti Instant 802.3af seems to do what you want (as long as the >> equipment can handle 16v) >> >> http://ubnt.com/8023af >> http://ubnt.com/downloads/instant8023af.pdf >> >> On Fri, Dec 31, 2010 at 9:00 AM, Robert E.

Happy New Year: Crazy Wiring
Here, for those who were involved in the "is that a picture of Manhattan with multiple phone companies" debate last week, is a link to the first of a series of linked blog posts, which contain a lot of those pics, somewhat better cited than I've seen before, along with a large collection of "thank ghod I don't have to deal with that" pictures of wiring catastrophes. http://www.darkroastedblend.com/2007/03/really-bad-wiring-jobs_20.html Happy Gregorian New Year! Cheers, -- jra
