Drighton posted:I create RMAs for faulty Cisco equipment. If you think your hardware has failed, try these troubleshooting steps to confirm it. I assume this means you work for Cisco? We have a 6509 chassis sitting here with a shipping label on it. It has been here for nine (9) months now. We have tried on 3 seperate occasions to get Cisco to take it off our hands, but they never seem to schedule someone to pick it up. We've gone through all the right steps (we thought?) on the website. This chassis is our old dead-ish one that they shipped us an RMA replacement for after having no idea why it was breaking. Kind sir, how do we get you guys to take it off our hands? It has been sitting there on its pallet for a long time, and has turned in to a table for our cache of 4948's. On a similar note, I have a Sup720 with what is likely a bad flash card on it. How much of a PITA is it going to be to get this thing RMA'd? I have been having a bitch of a time navigating Cisco's website to figure out where I should actually be entering this RMA. I've found at least 2 places. We have a service contract with Cisco.

Drighton posted:Sorry for taking so long to reply, I lost the thread and only just found it. I'll have to bookmark this for any further questions. Thanks for the info.  I had a nice long reply typed out and closed the tab.  The short summary is, as far as I can tell, the 6509 was shipped via a freight carrier or something. I'll have a look at it one of these days. We're happy to leave it sitting there forever. I'll be certain to include all pertinent troubleshooting information. I didn't spend my time in technical support, or berating techs now that I'm a sysadmin, to go and make someone elses life hell. (Or waste my time with half-assed emails.) I'm not certain on the exact part that needs to be replaced, but I do know that 0x2142 was being ignored and my NVRAM contents were being loaded, which was corrupt. Fun times were had by all.

Ray_ posted:I had thought of stepping up to Catalyst 3560 switches, but they're about double the price of the 2960 switches and I can't find any with 4 SFP ports. It's cheaper to get a 2960 and a Powerdsine injector than it is to get a 3560 with PoE. WS-C3560G-48TS is the part you're looking for, and they do have 4 SPF ports. I love these things, they're a good switch for a good price, if you do not need line speed backplane or jumbo packets. This is our single copper uplink port on one, during non-peak hours on a Friday: 5 minute input rate 160964000 bits/sec, 63472 packets/sec 5 minute output rate 424236000 bits/sec, 77443 packets/sec It gets up to about 700mbit output during peak hours. If you do need jumbo packets, we use 4948's, which are a bit pricier, but line speed and "full featured."

jwh posted:There are caveats, such as TCAM size, or features that aren't supported in hardware causing packets to punt to the processor, but you haven't described the need for anything that should be a show-stopper. Just make sure you keep your broadcast/L2 domains small and you should be fine. We use 4948's here, and they are pretty darn nice. They're similar in price to the 3750's, but pack a bigger punch, near as I can tell. If you don't need the backplane connectors, I wouldn't use them. If you're too worried about sales people, call up M@. He always seems to have the hookups. We have very few actual routers.

In any case, I didn't have much success either way. Actually, come to think of it, you might not need that Vlan1 junk in there at all. Our router is setup with a little 4-port switch inside it. Try sticking all that onto Fe1 and adjusting the various lines. Note that I have Fe0 hooked up to your interior office switch, and Fe1 hooked up directly to your router/modem's LAN port.

Depending on the router you can also export netflow information. I'm not certain how detailed the syslog junk gets, but netflow is fun to walk through if you have a server that can handle your bandwidth. If you want basic command logging, tacacs+ (aaa) lets you log user commands.

You would have to prepend the AS path with the non internap ISP since the internap connection has their clown AS between you and the ISPs they are connected to. I'm not really up on how BGP works entirely. I see our really quite long configuration dealing with what prefixes go where, but we never had any problems I can think of homing them with L3 and GBLX. We're trying (hear me Internap?) to turn up a 10gig line with them we ordered over a month ago at this point. They keep dropping the ball at various points. I think part of it is our sales guy, who at this point has stopped returning my calls. Either way, we've had the least amount of technical problems from them than any other provider with which we've gone. It's great, our Internap network technician guy pretty openly hates the entire non-technical staff, but he knows his poo poo and gets the job done, so they seem to tolerate him. Global Crossing and Level3 technical support can suck it. Seriously.

Or could you just do OSPF ECMP over a pair of 2-3x1GbE etherchannels and load balance at layer 3? We're using 6748's hooked up to 4948's. Most of this is L2 traffic going from web servers to their NAS boxes.

Perhaps I should put a second 6509 in place and just load it to the gills with 6748's and use it for rack aggregation? Use a 10gig etherchannel to get it to hit our BGP gateways, and move most of the OSPF stuff for those racks to the new copper monster. jwh posted:Wait, you had to burn three additional ports to solve the "odd-number" etherchannel bundle problem, or you had to burn three additional ports to work around some kind of asic limitation?

I would get the units they sell the most of in that feature range, so that they can be familiar with the units they sell. I assume this means something like a Cat4948, Cat 3570?

I'm having an oddball problem with a port on our 6748-GE-TX w/ 6700 CFC line card in our 6509 chassis (Sup720-3BXL) when connected to a 4948 switch running the standard image. We have it in a 4 port etherchannel, both sides configured identically using the range command. When the ports are connected, the 6509 side just blinks slowly green/off, nothing in logs, and it always makes me nervous to turn those on debugging/logging on that switch. The other side shows nothing, turned on all event logging for that interface and nothing comes up in the logs. Changed ports on the 6748 and it links up just fine. I suspect the port is simply hosed. Ideas? code:

I'll try this out with a cold 4948 and the bum port next week sometime. We use desirable for the other quoted reasons. We used to use `on`, but it's just too annoying having some douchebag with a laptop getting 500mbit of traffic destined for somewhere else. And we use the exact setup mentioned for core/dist(aggregation)/edge. 6509 with etherchanneled 4948's hooked up to it, and single-gig 2960's which have the servers themselves plugged in to them. Yes, 100mbit to the servers. We tend to use 3560G's for the filer edge, though.
