Why not: 1GB burst (100MB normal) Internet Carrier 2 $600/m + $15 copper fee Dark fiber to office $unknown- checking on (In reality though if you just go to the carrier and ask them to serve your address they should just figure this out for you and charge you a local loop) Then skip everything else. Make sure you understand how 95th percentile billing works as well.

Curious if anyone knows how the backplane of a 7600 identifies itsself as such vs a 6500? (Yes, I would like to flash a chip in to a 6500 to identify as 7600 so I can run SR.. vs SX..)code:falz fucked around with this message at 16:57 on Mar 15, 2014 |

This isn't really Cisco-specific but I'll ask anyway. I have like 5 dumbswitches I wish to consolidate to a single 24-port managed switch. They only have 2-4 ports used on each switch. I basically made a bunch of VLANs, numbered 901, 902, 903..., and assigned them to groups of 4-6 ports, and left port #1 on VLAN 1 so I can have it plugged into my existing network on the .1 subnet, for monitoring and such with the rest of my switches. So it's basically setup like this: code:It seemed to work at first, except one of the VLAN's didn't work at all. Then after a few minutes the VLAN01 port (#1) would quit working, as in I couldn't ping the management interface of the switch. But if I removed it from my LAN and just plugged a laptop into the VLAN01 port, I could access the switch just fine. Doesn't seem to be another device with that IP on the LAN. The other networks also started acting erratically. One VLAN is for a cable modem, the rest are for other things like T1's etc. Basically trying to combine all the little gray switches in this picture into one switch:  Any suggestions? I assumed as long as I used VLANs that I wasn't using anywhere else it should do what I want.

Issues with vlan1 could vary for many reasons. I'd just not use vlan1 and use a dedicated management vlan for the switch. How is routing happening for each VLAN? Do you have a router with at trunked interface facing the switch and IPs on vlan subinterfaces? Is the switch itsself layer3?

The 1234 is a layer 2 device - http://www.adtran.com/web/page/portal/Adtran/product/1700594G1/4 Routing is happening on the two main switches, one of which this switch is connected to 1.2 is the 'router' for vlan1, 2.2 is the router for vlan2, etc I don't have that setup for vlans 901, 902, 903... because I don't want the traffic leaving the switch, as it doesn't have a need to. I'm just trying to consolidate equipment. I had a similar problem before but that involved a trunk port that was passing traffic to the rest of the network (and I think my VLAN ID's conflicted as well), but I don't have any trunk ports configured on this switch I need to reconnect that switch to the network (I put all the connections back on the individual dumbswitches) and see if it drops on it's own, or only when I connect other networks.

We have a pair of next gen firewalls (fancy routers) in an Active/Passive Stateful HA pair. They have SFP interfaces and and we have been provided SC terminated cables from each of our ISPs. We have the Cisco GLC-SX-MM SFP 1000Base-SX transceivers but that would only allow us to connect an isp to one device. How do I configure this for a high availability failover? Is it as simple as getting a pair of these and hooking them up to my firewalls? http://www.acefiber.com/1x2-st-to-lc-splitter-50125-multimode-850-20mm-p-183315.html  Basically, how do I create the RED lines?

You can't splice that way. You'd have to terminate one ISP on each frewall and track the interface/routing, when it fails you failover to the standby unit. Also if they terminated SC you'll need to 1) Verify if it's single mode or multi-mode since you have a MM transceiver and 2) Get a SC-LC converter to plug into that LC transceiver

If all your gear is in a rack I would say terminate the ISP whips onto a patch panel. Much easier that way to just patch them down into your firewalls. Loop and hangs can be a pain :/

Anyone familiar with Cisco WLC 5508? We have a 100meg symmetric connection to our provider and everything is gigabit to the APs. If I'm wired directly into the switch, I'll get like 12MB up/down as I expect. However over wireless I'll get like 250kb down and 3meg up. So wtf? I understand wireless isn't going to be as fast as wired, that's fine but why the huge disparity between down and up on wireless? Honestly if the down/up were both 3meg, there wouldn't be a problem, but 250k down is unacceptably slow.

Are you on 2.4ghz or 5ghz, what's your RSSI, did you run inSSIDer to see what kind of overlap/co-channeling you have, what's your client statistics on the 5508? Further, what kind of AP? Is it MIMO or some piece of poo poo one antenna thing? Your high upload and lower download makes me suspect it's just a crowded channel.. You can download cisco spectrum expert and plug in your AP's Network Spectrum Interface Key and check the amount of congestion on the channels Sepist fucked around with this message at 17:04 on Mar 20, 2014 |

This is a test network in a relatively clean air back office with a single 3602 AP, I've also tested on a LAP1131AG and gotten the same results. Within the "production" environment which is a wild-west as far as competing Mifi's many more users, etc, the results are similar. The WLC is connected to a 2960S with a 2gig port-channel and it's absolutely not saturated or anything like that. The only "odd" thing is that the APs are on a management network that is completely independent from the external network. i.e. the AP sits on network 10.1.10.0/24 but all wireless clients are on 10.1.16.0/22 and so the WLC is doing the switching from the management network to the external network. 10.1.16.0/22 then gets NATTED by an ASA 5520 to our public segment 190.x.x.4 http://www.speedtest.net/my-result/3384084275 This is from my laptop, but alas iphone/ipads are 5Mb/s slower on download and 3Mb/s slower on upload. Hmm. Maybe I'm getting closer: This is from the "production" network. http://www.speedtest.net/my-result/3384096277 And this is through the same network, but on a stand alone linksys, thus bypassing the WLC. http://www.speedtest.net/my-result/3384107624 ate shit on live tv fucked around with this message at 18:10 on Mar 20, 2014 |

This has been driving me crazy all day and I feel like I'm missing something super obvious. I just installed a new Catalyst 4510 (Switch 1) that is connecting back to another 4510 (Switch 2)in our data center over a layer 2 port channel. I am able to ping between the two switches on their management VLAN addresses, and from the new switch to any other switch in the /24 management VLAN. However, any traffic to or from the new switch to an outside network never makes it past the gateway. None of the other switches in this /24 VLAN have any issues at all reaching outside networks. There are no access rules on Switch 2 that would block traffic to Switch 1's IP address, and no firewall in the way either. Switch 2 can reach every other device on the management VLAN with no issues. The port-channel and trunk link configs are extremely basic: Port-channel interface Port-channel 9 switchport switchport trunk native vlan 10 switchport mode trunk switchport nonegotiate Physical Ports interface range TenGigabitEthernet1/1 , 1/5 , 2/1 , 2/5 switchport trunk native vlan 10 switchport mode trunk switchport nonegotiate channel-group 10 mode on I've even tried cutting everything down to a single trunk link and eliminating the port-channel altogether, but had the same results. We have two 4506 switches hanging off of Switch 2 in the data center as well, configured identically to this 4510 and they have no problem sending and receiving traffic across the management VLAN's gateway. I'm kind of at a loss as to what may be causing this.

Looking for a solid answer to this. Opened a ticket with Cisco to RMA the fan try in my ONS 15454, and at first he told me they're not hot-swappable, then he told me they were. I've been trolling the internet and I can't find anything that says specifically whether they are or not hot swap, and I don't want schedule a maintenance without knowing whether I need to deal with downtime. I can't imagine it's NOT hot swap, but there's nothing anywhere that I can find that says it is.

They are hot swap. IIRC you have somewhere from 30s-2min to get the new one in.

We need to use the datacenter remote hands, so I'm not sure how quick they'll be. This one's not decked out, just XC, TCC, and a couple OCx cards, so I imagine it shouldn't be generating too much heat. Thanks guys.

less than three posted:Typo? Yeah that was a typo, the channel-group was set correctly - I was just really tired when typing this out. I actually managed to figure it out and it was extremely stupid. no ip routing  The image these switches came with had routing enabled by default, but we're only using them as layer 2 switches. Since the routing was enabled, the switches were ignoring the default gateway for the management VLAN. It just never struck me because ip routing doesn't show up in the running config and this is the first set of L3 switches we've ever ordered that had an image where the routing was enabled by default!

Pretty much it just hits overtemp and shuts down. I would still do it in a window since poo poo happens. You just grab the latches on either side and pop it out. Push the new one in and wait for the front display to boot.

The reason they give for "C" being incorrect makes no sense; C wasn't implying that telnet/ssh take any part in the CDP process, all it suggested was that you ssh to something directly connected to your target device and run CDP there which is a perfectly acceptable answer.

Well if we want to get really technical, you could get CDP information from the remote device provided that the inbetween devices forward or tunnel rather than just process frames that has the Cisco CDP multicast destination MAC address.

Cross-posting from the general IT thread since I just remembered this one exists. My company is hiring if anyone wants a network engineer job in Denver. PM me or reply here with an email address if you want details. Guess I should do a formal post in the job fair thread at some point. Looking for roughly CCNP level experience though the actual cert isn't a hard requirement since we don't in fact run much Cisco gear. Juniper, Force 10, F5. Linux expertise a huge plus. You would be the primary network engineer for a mid-size web property. I hesitate to call it a "startup" since they've been around for going on 10 years but it still has that kind of cultural workplace feel, for better or worse. Full-time remote is not an option but frequent work-from-home may be as long as you're in the general area. I am not the hiring manager, just a sysadmin you'd be working with, but I can pass resumes along and put in a goo
