When I'm working on an implementations team, we might have to rack some 6513s, 4510Rs, 4506s, and a number of 3750s, 2960s, etc, as part of the implementation. And program them. I've even had to run cable every now and again. But, we're generally set up so that if you can't do heavy lifting, there are plenty of other things you can do, and plenty of other people to help out.

I went through the cisco networking academy for the previous curriculum, so I didn't learn about some of the newer items on the curriculum like wireless(I think). For the CCNA you'll probably be fine just using GNS3, provided you have access to some router IOS images. I passed it pretty easily without ever really using any physical equipment to study.

They do voice vlans. There's a quasi-CLI available through the web interface, but it's all one command at a time, submitted through a web form. Handy for showing CDP neighbors and a couple other things, but I wouldn't want to configure one from it.

That's on 7.1, but I'm pretty sure 8 is the same or similar enough. I know that 4.x was pretty much the same as well. Also, the number you put in the incoming number field may vary depending on what your provider is forwarding you through the PRI. We're using AT&T here.

A partition is a group of extensions. Every extension must go in a partition. Partitions are used in calling search spaces. In order for one extension to call another, the receiving end's partition must be configured in the sending end's calling search space. The calling search space is the group of partitions which a phone or line has permissions to call. All of the logical groups have a purpose in CallManager, they're just not all readily apparent.

Your ip route command is wrong. Unless, of course, you want to send all requests which are intended for inside the network to outside the network. should be: ip route 0.0.0.0 0.0.0.0 111.111.111.112 That way it will send requests for anything not locally connected to the outside network. EDIT: Also, you don't have any DNS servers set in your DHCP pool. Not really a problem, but unless you've manually set DNS servers on each of your clients you could possibly run into issues. n0tqu1tesane fucked around with this message at 15:12 on Jun 21, 2010 |

I know a 6500 chassis is in that list, not sure about a 4500 chassis though. I know Cisco has had some supply problems over the last year or so.

Bardlebee posted:I have dreams of working with equipment like this. Count your blessings. The supervisor linecards for the modular chassis switches like the 4500 and 6500 series switches are basically the brains of the switch. It's where the main processor and IOS of the switch are housed. It's where any layer 3 functions are handled, etc. Most chassis are built for only one supervisor linecard, but some have two, for redundancy. The 4510R has two supervisor linecard slots, for example. Most supervisor linecards have two gig or ten gig gbic slots. Of course, the two 10 gig slots on this one are going to have adapters that let you use two gig SFPs. The one with the bad sup linecard has two 48 port gigabit POE switch linecards, two 48 port gigabit linecards, and a 24 port SFP gigabit linecard. Not sure why they ordered the SFP linecard, but I think it was grant money, so whatever. This new sup6-E linecard is pretty cool, and I do like that Cisco is moving toward USB for console access, but I wish they'd pick one USB cable and stick with it. The linecard has a big old standard B type USB plug, while the new routers all have microUSB plugs. n0tqu1tesane fucked around with this message at 23:11 on Jan 6, 2011 |

adorai posted:it was a tossup whether I should post this here or in the asterisk thread. Are you going to have PSTN access at the branch sites other than the SIP trunks? Are you planning on using SRST? What are your plans for calling 911 at the branch sites? What we usually do for customers if they have a main office and several branch locations in a general metro area is to have one or two POTS lines at each branch location and a PRI at the main location. Incoming calls to the main lines at the branches come in over the POTS lines, and outgoing calls go out over the PRI at the main location. This way you save money by bundling and sharing the bulk of the lines over the PRI at the main office, but each branch also has at least one POTS line to make/receive calls over in SRST mode in the event of a WAN or datacenter failure. Also, all 911 calls are routed out over the local gateway through the POTS line at each site so the e911 information is correct. If you terminate at the branches, the RTP stream will only traverse from the router to the phone.

adorai posted:We are going to continue to terminate a single pots line (shared with the alarm) for 911 access. I did some experimentation today, and it looks like the CUBE router relays all traffic, including RTP, through our call manager. I am using sip to sip, not h323 internally. Are you sure all the traffic is hairpinning through the callmanager? I know in traditional voice gateway scenarios with POTS or PRI lines, it doesn't, and I don't see why it would with the CUBE. In fact, this Cisco whitepaper sells the CUBE on the fact that remote sites don't need to hairpin the voice traffic through the central CM. http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/gatecont/ps5640/cis_45835_cube_assets_wp1e.pdf (Page 7-8) Granted, I don't have much experience with the CUBE. One of my coworkers is working on his CCIE Voice, and has played around with the CUBE quite a bit, so I'll run it by him tomorrow.

Erwin posted:Okay, another dumb question, but I want to confirm my understanding coming from the Procurve world: Like ragzilla said, the "switchport voice vlan 10" will accept tagged traffic intended for vlan 10. This allows you to use the auto-qos command, and traffic going over the voice vlan will be given higher priority. On the newer switches, a port configuration for a phone with auto-qos would be done something like this: interface GigabitEthernet1/0/14 switchport access vlan 100 switchport mode access switchport voice vlan 10 auto qos voip cisco-phone The "auto qos voip cisco-phone" command will add a few other lines of configuration to the port, and a bunch of lines of configuration to the global config. You could use this config on all your ports, and will allow you to move phones around without having to reconfigure the port every time. It'll keep the PCs on your PC vlan, and your phones on your voice vlan. You can also configure the ports as a trunk, and connect a PC to it. Since PCs don't normally tag their traffic, it'll default to sending the untagged traffic over vlan 1. You can configure this on the port as well, using the "switchport trunk native vlan XXX" command, which will put all untagged traffic coming in on that port into vlan XXX. Older Cisco switches, such as the 3500XL switches, didn't automatically trunk the port for a phone with the voice vlan command on an access port, and the port had to be configured to trunked. This way, if you had a PC hanging off the back of a phone, you had to use the "switchport trunk native vlan" command to put the data from the PC onto the correct vlan. For purposes here, this command functions the same on a trunk port as the "switchport access vlan" command works on an access port. Such a configuration would look like this: interface FastEthernet 0/14 switchport mode trunk switchport trunk encapsulation dot1q switchport trunk native vlan 100 switchport voice vlan 130 With a trunked port though, by default it'll accept tagged traffic for any vlan, which isn't always desirable for security reasons. The voice vlan command only accepts tagged traffic for the voice vlan, and not for any others. EDIT: Wow, that's a lot of

Pvt. Public posted:My question is thus: I know the 7945Gs will the fine for normal desk phones, but will the 7965s with the 7916 expansions be sufficient for operator/receptionist phones? The main functions these phones need to serve are to display all active user's desk phone line status (incall/dnd/offcall) on the expansion display (so they can see when someone is on the phone), field incoming calls on 4 lines, paging over intercom (phone speaker) and park calls to 4 hold extensions for pickup. Yes, a 7965 with 7916 would work perfectly for what you want. You can use a busy lamp field/speed dial button to monitor and call all the other extensions in the office. You can also hook up two sidecar (7914, 7915, 7916) modules to a single phone. One note though, if you ever move up from CME to full CallManager, CallManager does not do paging/intercom to multiple phones at once like CME will. You can do single phone to single phone with CallManager, but not a "broadcast". There are also several ways to deal with the calls to the incoming lines. You can actually have all 4 lines ring to a single directory number on the phone, leaving additional line appearances open on the phone for more lines/features. Also, unless you have a real need for color screens on your new phones, I'd just buy 7942s and 7962s. I'm a little rusty on CME, but let me know if you've got any more questions.
