Partycat posted:As he said the cycling lights mean that it is trying to join the controller. If you look at the console it may give you an idea why it left the controller. AFAIK it won't move between controllers until it loses contact or is booted, so I don't see why DNS would screw with it once it is already online. I'm gonna go out there at some point so I can see exactly instead of having it relay. I got the "broken" one here and put it on our WiFi network. It cycles through various colors, white, amber, blue, etc. Goes green for about 5 seconds and then blinking red. So I think it's actually bad.

I know there's a couple ONS guys in here, and hopefully someone has seen this before. Our Smartnet expired and it's going to probably take 2 or 3 more days for the renewal to go through before I can get a ticket open with Cisco, so here I am. I was able to log into the node when it was here, we shipped it to the site, and now I can't log into it. Here's the text I'll enter for the Cisco ticket: We have a node that we are unable to log into. When we type the username and password into CTC, we get a couple different error messages: "A failure occurred during IOR Repository Initialization. Please wait. CTC will try again." or "A failure occurred during User Authentication. Please wait. CTC will try again." In either case, we hit the OK button, and it tries over and over again until we give up. It seems to be the correct user/password, because when we put the wrong ones in, it immediately kicks you out and you have to put the user/password in again, so I suspect I'm entering the correct credentials. We have tried pulling the active TCC2P card and failing to standby, but same issue happened. Tried power cycling the shelf, same thing. Any ideas?

I've got an architectural problem I need to solve, and I believe I know how to solve it but I need some guidance on the configuration. Backstory: In our corp network we have a pair of Checkpoint firewalls in HA and 1 ISP which handles all of the traffic (internet and site to site VPN to colo). We recently brought in a second ISP (Comcast) which we want to send all of the internet traffic out of, leaving the site to site VPN on the old ISP. We got all of this configured and working how we wanted it, but when we tested a failover of the Checkpoints, outbound internet traffic failed until we rebooted the Comcast gateway. After speaking with Comcast tech support they said its a known issue that the Comcast gateway holds on to the ARP table for too long (sometimes hours) and this is why traffic failed. Long story short, they don't have another solution because we have a static IP and that equipment is the only one that works with that. Here's the Cisco question: I have a Cisco 1841 which I was going to put in between the Comcast gateway and the Checkpoints (so it can handle the ARP if the Checkpoints failover) but I'm not sure how to configure it. Comcast gave us a 28 bit subnet and I can use any of the IPs on it. I was thinking of splitting the subnet into 2 29 bit subnets, and putting one on each interface of the 1841. This will allow the Checkpoints to still have their external IPs. I'm just curious if I'm making this more complicated than it should be, and if not, how would I go about configuring this on the 1841?

Use a switch. Create an SVI that is the comcast public /28. The comcast default gateway is say .1 Your Checkpoints are .2 and .3 and the virtual address is .4. You still have a single point of failure, the provider and the switch, but now your checkpoints will be able to fail over gracefully. Actually you dont even need the SVI, just a vlan. ate shit on live tv fucked around with this message at 21:34 on Mar 21, 2012 |

Ok, I put a 3750 in the middle of the gateway and the Checkpoints (vlan 50) and rebooted the gateway. Now both of the checkpoints can ping the gateway, but they cannot ping the outside world. A traceroute doesn't even show them getting to the gateway. I've tried configuring an SVI on the vlan as well, but this did not change anything. Any thoughts?

I was wondering if anyone had a great guide for implementing and supporting cisco callmanager environments. I will give a brief description of our voice situation, which was initially implemented by a vendor that sucked and we have muddled our way through it despite the implementation. I now want to make sure it is awesome. We have ~50 locations, 6 of which are cisco cucm sites. These 6 sites have approximately 50 phones total, each site has a 2901 or 2911 router. 5 of the 6 have FXO gateways, 1 is t1 E&M to a legacy PBX. We have a physical server which is a CUCM publisher and a second CUCM server which is a VM. All phones point to the publisher for TFTP and for their call manager server. We have various amounts of DSPs in each router, each router is licensed for SRST but likely doesn't have much in the way of functionality in the event it is severed from the WAN. We also have a CUCX server (VM) for our helpdesk, but some remote non-cisco sites are unable to call our helpdesk, they get dead air. most remote non-cisco sites talk to the cisco locations via H323. Basically, I think the environment is jacked up because we don't know poo poo about transcoders, conference bridges, or cluster failover. It works just fine as is for what we use it for today, but I want to make sure that as we grow (we will be adding roughly 100 phones in the next 3 months) that I am not moving my end users into an environment that is destined for failure. This thread is not the right location to flesh out my design, I just need some documentation or a book recommendation that will go over most of the basics, and give me the base knowledge I need to even know what else I need to learn more about. I have a general cisco voice book from cisco press, but it seems to be geared more toward enabling legacy PBXs to talk to each other through cisco.

I stepped into a similar situation about 3 years ago. Adds/Moves/Changes/PRI/SIP, no problem. Then we started running into all kinds of weird little issues. Random drops, VM issues, licensing, etc. The environment had not been managed a couple of years before that. We tried fixing things at first, which we were able to, but it took a bit. After internet and email, phones being down will get you screamed at, screw SAP, SharePoint, etc. being down. And in multi-tenant buildings or campuses you have e911 to contend with. We had a group come in, document everything and make recommendations. We had them work through a couple of recommendations, but their engineers ended up being flaky. Had the same problem a few more times, got fed up with it and went to Cisco and asked who they recommended. They can't "officially" recommend one vendor over another, but they got us in contact with the right folks and we found a group we're happy with. Our knowledge has grown 10 fold with this, but we can't justify a full time voice engineer, even with 1200+ phones, but getting someone else in to do a health check was very much worth the cost, time, and travel. Phones are also kinda like PCs. Go to a small or remote site, they find out you know something about them and you end up having 20 new tickets sitting in your queue for appearance or VM issues when you get back.

How do I connect an ASA 5505 to my UPS? The power cable has some tiny proprietary connector on the ASA end and a standard 3-pin UK mains plug on the other. I need the same thing but with kettle on the end, or a mains female to kettle cable, if such a thing exists. It's proviing impossible to find because all I get is hits for standard kettle leads.

While I can't help you directly, this might help you in your search: Those plugs have standardised names, which you can lookup here for the UPS side and here for your British plug The "female kettle plug" you are looking for is probably a C14. I think your male plug is a BS 1363. Good hunt.

It's like two small squares with a clip above it, I've never seen anything quite like it before so I'm assuming it's some kind of proprietary Cisco nonsense. Edit: I'm dumb, the cable has a PSU halfway along it with one of the standard connectors from your link on it (C6), I just needed to find a cable between that and kettle which was easy. Thanks!

3750 can not support multiple subnets in it's DHCP server pool config. Is this an issue that can be fixed with a different iOS or is there a different Cisco switch that I can replace the 3750 with that will handle multiple subnets within an individual pool?

After having some consistent problems with 3rd party optics we buy all of our stuff Genuine Cisco, however we do use "gray-market" optics for a decent discount. Of course this is a financial company so budget isn't really a problem.

Yeah actually I was just about to ask this. I have an HP BladeSystem Cisco GESM that I need to source two or three SFPs for. There shouldn't be anything HP or Cisco proprietary about the SFPs, right? I only ask because I have zero experience with SFPs. Everything I read says I should be fine just buying something off eBay but I wanted to doublecheck.

There shouldn't be anything HP or Cisco proprietary about the SFPs, right? In *general* all SFPs are universal. However certain older spec SFPs won't work in certain older switches. In some cisco switches you have to use some undocumented commands to allow generic SFPs, HP may be similiar. To be safe and if you are buying a lot of optics, use whichever HP recommends.

Ah. Well this is just for a little pet VMware lab I have. I need two more gig phy RJ45 uplinks for my iSCSI target machine so I was just going to get three SFPs off eBay and pray for the best. I figure I guess if they don't work I'll just flip them on eBay and hope someone picks them up. If this was an actual business thing I would definitely just spring for some first party components  some kinda jackal fucked around with this message at 22:17 on Mar 26, 2012 |

Most (good) third party optic manufacturers will use valid vendor serial numbers for the SFPs so the box won't even know it's a third party optic.

Martytoof posted:This is probably what he means. Yep. I had to use the service unsupported-transceiver command when I was doing a migration from brocade to cisco. The total number of optics was in the hundreds, and they wouldn't work on Cisco switches, at first. I happened to remember that command existed from my Service Provider days and came in and basically saved my company like $10,000. I guess one of the lessons that Experience teaches you is that saving your company a lot of money net's you zero reward.
