Hi, Got an issue I'm banging my head against the wall. I've hooked up a Cisco 2960 to a Dell M6348 over an etherchannel trunk supporting 2 VLANS. The Cisco switch is happy as larry as far as I can see. DMZ2#show run int po3 Building configuration... Current configuration : 117 bytes ...

Just FYI I don't know if this is new or not, but it seems Cisco themselves have started doing virtualised labs for many of their certs. May be worth checking out, I don't know how good they are or are not, but pricing seems reasonable. Main site...

Hi, Currently I have two seperate domains not related. 1 is deployed on our LAN and another on my DMZ. Due to some new requirements I have had to setup a one-way trust between the two so our LAN user access to the DMZ based servers can be controlled. This has been done and works on my test...

Hi, Wondering if anyone can shed some further light on some issues occurring on my Win 2k3 sp2 cluster. We had a random failure on our active node over last weekend. The second node saw this and tried to take control, however, the following problem occurred (from the cluster.log). WARN...

Hi all, as one of my New Years resolutions I'm planning to further my Cisco certs and was considering CCNP as next with SWITCH first (due to my work which is more layer 2 focused). However, things change and I'm now planning on moving house which means I don't have the space commitment for a...

Hi, Got a problem with a Cisco Aironet 1231 IOS ver 12.2. Maybe you can help? :). I'm not too hot on my WiFi tbh. A colleague setup this device as a quick fix before buggering off on holiday for 3 weeks. It acts purely as a secure wifi connection into our LAN for some testing purposes. We...

Hi, I'm trying to beat down management with a large stick on our A/C in our server room. I'm absolutely convinced it's waaaaay too hot in there, although I don't have an ambient temperature monitor for the room I would guess it's comfortably 30+C on average across the room. However, the temps...

This is a bit of a long shot but you never know what others have seen. I have a situation where it seems the Loopback NAT rule for a public IP address is simply being ignored. I have a rule as follows, created by the wizard: Firewalled Subnets xxx Public xxx Public xxx Private xxx Services...

I'm just playing with some lab stuff and something came up that seems overly complex and I wondered if there was a simpler way to do it. My routing table is: C 10.100.100.0/24 is directly connected, Vlan15 C 10.100.101.0/24 is directly connected, Vlan12 C 10.100.99.0/29 is...

Hi, It seems a little dead in here but here goes anyway. Posting for a friend and wondered if anyone has experience of dealing with maintenance pages on large scale (multi-server) sites? We're trying to find an efficient way of putting some 50+ sites across multiple servers into maintenance...

Hi, I've been having a bit of a nightmare with our primary SQL cluster recently. Following some firmware upgrades to both servers one has decided that it wanted a divorce and it refused to start the cluster service generating an error each time, nothing useful simply 'Cluster service refused...

I wonder if anyone can point me in the direction of where I can find information on dealing with Multicast when there is no need to route and/or no facility to route it within the network. Is this covered in any of the Cisco training areas as everything I've found on it thus far refers to Layer...

Hi, I used to have an extremely handy PDF document detailing various Cisco router performance levels, how much they could route in bandwidth and pps etc. I've googled and searched Cisco's site for it and can't find the bugger. Does anyone have a link to it or the PDF itself I can grab or...

Anyone experienced any issue where newly defined interfaces do not become available until the sonicwall is rebooted? I keep finding this and it is a huge pain as even with a HA pair I can't justify a reboot until out of hours where as there have been several occasions when I've needed to setup...

We've recently had some issues and I have a good idea where to take it but would like confirmation of what I'm already thinking. Ok we have a small single site AD domain and were looking to replace a couple of dated DCs. We built up a new DC done all the bits and stuck it in. A short while...

Hi I've been doing a CCNA course through my local college with semesters 1+2 now complete. From my understanding that should give enough grounding to do ICND1. Is there any benefit in doing either ICND1 now and then ICDN2 later or waiting and doing the single exam? I've heard that the CCNA...

Hi wondered if any of you guys are able to shed some light on this. We've recently had our new building fitted out and we specified cat 6 cabling to all points. This was to be installed as part of the fit out. Separately we had some interrack cat 6 install done by a cable specialist who had...

Wasn't sure whether to post this in the Switch or Routers section but I picked here. I'm currently seeing something really weird via CDP on our switch and routers. We have 2 Cisco routers on the edge of our network these connect via a non Cisco switch and then to a non Cisco firewall then via...

Hi I'm very green to linux and have been requested to make changes to a server's filesystem so more space is available. Essentially what is wanted is make some of the un-used space in /usr available to /var. I've googled this and found various bits of information but none of it makes a great...

Hi, We're currently building a new domain for deployment in our DMZ. It's required due to a need for a SQL cluster. Our plan is to create a new forest and domain and setup a one way trust from the LAN domain to the DMZ domain. The trust aside, does anyone have any tips or advice for hardening...
