I am currently working for an org where we are removing our Meraki infrastructure. Nothing is set in stone yet as I need to check all the politics involved, but we are looking into donating our old switches, and later, wireless. I’m just using this to gauge interest, below will be the requirements and terms for anyone interested: -Name of school/charity -Location -Current switching infrastructure -How the switches would benefit your school/charity On top of the above, anywhere potentially selected would need to confirm all correspondence from their organisational email address, and have approval from the business manager or headteacher. The equipment would be donated on an as is basis, a document would have to be signed saying they will not be sold on for profit, that no warranty or support is implied or given, and that they will be disposed of correctly come their EoL. A license will be required for each device, but I believe Cisco offer very good rates for non-profits. At the moment our inventory is over 350 switches. Batches should become available between May and Dec this year. All switches are MS120 series, currently still on sale and in support. The majority are 48 port PoE, with some 24 port PoE, and some 8 port PoE. We will also have MR44 access points become available this year, but we do not yet have dates for these. We are located in the North West. Any potential interest please let me know below, along with how many devices you would need. If there’s enough interest, I can take this back to management and hopefully make this works. Cheers

Hi All, ODD one. We use a 'route-map' to determine what to forward to our smooth wall cluster for filtering (or really the loadblancer). and this route-map refers to an ACL which defines if its a network we want to forward on or circumvent the smoothwalls. Up to date this has worked perfectly. However: as of a few days ago. Our ACL which contains an object-group (with a load of Microsoft Ip's in). Seems to only process down to the object group part of the ACL. Everything after that seems to be ignored. (or thats what the hit counters when viewing the ACL would appear to indicate along with Ip ranges suddenly not receiving transparent filtering) My question anyone has seen this before/know a fix? Thanks

How do you learn CCNA using home lab used hardware ?
albertwt posted a topic in How do you do....it?
Hi Everyone, I'm planning to learn CISCO CCNA, does the following hardware is good enough to get to know basic IOS stuff ? Cheers, Albert -
We have a dedicated call center in our hospital. We are using a IP PBX software from a outsourced vendor. The software is installed in our PCs to attend the enquiry calls.The client pcs using in call center is a data vlan in one of the access switch. The server IP PBX software is installed in data center server farm switch. For the past weeks, the software was having some issues at some time, when i checked with the vendor they said software side is ok upon checking on wireshark logs. They have made several observations & fixes - Key Observations: Wrong Sequence Number (Red Entries) - RTP packets are arriving out of order or being lost, likely due to network congestion or QoS issues. High Jitter Values (Max: 7.03 ms) - Increased jitter can degrade voice quality, causing choppy audio or lag. Packet Loss (0.00%) - No significant packet loss was observed, but sequence errors suggest potential packet reordering. Clock Drift (-79 ms) - A lack of synchronization between sender and receiver clocks can impact audio quality. Cause - Solution. Network Congestion - Prioritize RTP traffic using QoS settings on the firewall or router. Jitter & Delay - Implement jitter buffers or increase buffer size in VoIP settings. Packet Reordering - Check network routing and MTU settings to prevent out-of-order delivery. Clock Drift - Ensure both endpoints synchronize time using NTP. Pls help me what to do from the core switch side or on the access switch side. NOTE- When I checked the ping status from the client PC to Server IP there is no drop or that much latency. Core switches are CISCO 4506 model Access switch for call center department is Aruba Instant ON 1930 model.

Ok, Quick question, I work in a High School and ive been asked to research into setting up Guest Access on are wireless for users that don't work in are school and things like Iphones etc without having to give out the WEP Key to teachers and such like. All I want them to have is Internet Access nothing more like file sharing etc. I've noticed the new Apple Access points can do this, AirPort Extreme Base Station - Apple Store (U.K.) (See guest access) we have Cisco Aironet 1230AG points all over the school and i was wondering if anyones had any experience in configuring them?? We are a brand new school (well 2 years old) so are tech department has pretty new equipment and i hope are points can do this. Thanks Steve

I've got a new Cisco 2851 with 20mb of a T3 going in one end, and two gigabit ethernet ports coming out the other. Our student net is currently plugged into one of those ports, and nothing's on the other. Soon we'll move the faculty/staff net over to the unused ethernet port. It's currently on a different router with a different pipe. Output of "show version" starts with this: Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version 12.4(3g), RE What I want to do is split our 20mb connection to 15/5 between the 2851's two ethernet ports. Our student net would get 15, and our faculty/staff net would get 5. I'm pretty sure I can configure the second port to get the network up, but I'm not confident with limiting the bandwidth usage. Here's my guess at the rate-limit command: config terminal interface g0/0 rate-limit input 15000000 24000 24000 conform-action transmit exceed-action drop rate-limit output 15000000 24000 24000 conform-action transmit exceed-action drop Does that sound right? Do I need to provide more info?

Hi all, I consilidated two switches into a stack. both have multiple VLANS and I'll give an example here; sw1 vl 2, 3, 4 sw2 v 12, 3, 4, 5 I decided to re-use sw1 and keep the config and wiped sw2 and stacked. So far so good. After configuring the uplink trunk to allow vl's 12 and 5 this is what happens vl5 works fine vl12 picks up an IP address but can't go anwhere, can't ping the default gateway etc. It can ping other devices on the same switch stack. So conclusion is DHCP is fine as it uses broadcast any vl traffic for vl12 isn't leaving the switch. I can't see any reason why I've checked for relevant ACL's both on the edge switch and the core switch. These are all Cisco switches. Can anybody think of what I'm missing?

Ghost 11 and Cisco SG200-50 Switches
gr8pretender posted a topic in Network and Classroom Management
Hi everyone. I've combed all kinds of different forums searching for an answer and have yet to find a similar case so I guess I'll start the precedent here. Pretty much our situation is that we have classrooms that we occasionally have to clone with Ghost 11, the switches in place in each room are really slow so we bought these new Cisco switches (SG200-50) to deploy the image. Pretty much our issue is at least a 15% of the clients fail every single time. They are giving a "client timed out" error, it freezes up the ghostcast and slows down the whole process, and a lot of the time even 50% end up failing when all is said and done. We can usually unicast/locally clone them when they fail, even through the switch with enough tries. It seems pretty random so we can rule out ports pc problems, all the managed switches and un-managed switches seem to have this problem. I've read several articles about tree spanning and Symantec has said that its because we need to enable IGMP (which one of my co-workers argues has nothing to do with multi-casting) and I'm not the most knowledgable with this kind stuff so I'm just playing middleman between my co-worker and Symantec/Cisco technicians. Anyone have any ideas how we can get little to none of the clients to fail? -
We use Cisco Meraki as our Wi-Fi system and for our BYOD SSID we use 802.1X with PEAP and MSCHAPv2 so users can connect personal devices to Wi-Fi using their same login and password that they use for the computers / email / etc. A few weeks ago we found it necessary to enforce a password change on all our users. Unfortunately, although we did mention to them that they would need to update the wi-fi settings on their personal devices, we're still seeing a high level of authentication failures on the Meraki dashboard. Can anyone suggest ways in which we can deal with or mitigate this? Is there a way to force devices to re-prompt the user to re-authenticate? Or even to force the device to "forget" the network if their authentication fails a certain number of times? Would increasing or changing the lockout duration on users' AD accounts help at all?

As we all know, CISCO have updated their CCNA & CCNP qualifications. I have my CompTIA A+, Net+ & Sec+ and a couple of years of being a technician behind me. I really want to get stuck into one of the new CCNP paths. If I want to go for one of the new CCNP certs should I do my CCNA first? When I look at the exam contents for the new CCNA it looks pretty similar to the Network + and I don't want to waste time & money getting essentially the same cert twice. But on the other hand I don't want to invest time in the CCNP only to find that I'm way out of my depth. Any advice would be much appreciated.

Greetings! I've got a bit of a strange one, its either related to my router or Server essentials 2012, but i can't find anything wrong on the router yet, so I thought i'd try here. I recently swapped out a basic linksys router for a Cisco RV042G, as part of a future plan to link to sites together. I copied over all firewall and static IP assignments, and bingo! everything is peachy. Except, they can't resolve their own website. Of course, i assume this has to do with the router, since it wasn't an issue before, but i can't see anything wrong. So, i'm assuming i might have done something wrong on the DNS module of SE2012, that was somehow a non-issue until i switched to a "pro-sumer" router. They can visit any website, but their own. other possible relevant info: Website url is www.businessname.com local domain is businessname.local server has its own IP, as well as 2 ISP and 1 Google DNS entered into the NIC settings, but just 2 ISP and 1 google DNS entered as a forwarders. computers connected to the network, use the Server's IP, and one ISP DNS address. this is driving me crazy and i think i don't quite know enough, and instead have just made myself dangerous, instead of useful. Thanks in advance, Doomed.

OK, CISCO is causing me a headache, any experts out there willing to contribute would help tremendously! I have a Direct Dial Number that when I phone it, it automatically hangs up. Now obviously this is because incoming calls to that DDI are being refused/denied/blocked. Problem is, I cannot find where to re-enable for this extension. Any pointers or general shoves in the right direction greatfully received! Thanks

Running a command such as $CDAMaps.ClientIP.TrimStart("cda-request={entity-attr:entity-id:ip=") Trims the surplus text from the IP Address field, but does not write these changes back to the table. Any suggestions on how to get this table formatted correctly, and how to then compare to my $adusers list to get the two outputs would be greatly appreciated Diolch
