Hi, The last months we replaced all our access switches by Cisco 2960x switches. The next step is to replace the distribution switch where the access switches are uplinked to. My question is what would be the best distribution switch to chose here? It's about 25 x 2960x access switches. and goal is to have the uplinks 2x10Gb The idea is to have a redundant setup with stacking, fabricpath, ... or something else. What would you chose in such situation and why? (FYI Core switches are Nexus 6K with FEX) I'll also attach a document with possible candidates) Kidn regards Steven ... View more

Hi, We came at the point that we going to implement MST in our organisation. Why? Well we've bought new HUAWEI CORE layer switches (over 2 DC's) connected with DWDM. Because the HUAWEI do not speak pvst+ or rpvst+ we are obliged to move to MST, well not exactly but to get the convergence time under 1sec we're thinking to  migrate and offcourse to loadbalance a little Huawei is speaking MSTP standard and our former core switches catalyst 4500 switches (which are now distribution layer) have been upgraded so they can talk MST  as well according to the standard. Because the region we're going to create will span two different sites, I'm wondering the following. We have 4 catalyst 4500 switches beneath the huawei cores. 1. Do we need the trunks that interconnects the switches inside the region configure with all vlans allowed?      For the moment some dmz connections are only connected to 1 or 2 distribution switches and not all      And for the moment we have sometimes differnent trunks between 2 core switches with different vlans allowed on them ...

Hi Community, We're having kind of a problem with our Catalyst 4507r switches. If we do a "show interface" command we're getting a lot of " Total output drops" on some of our interfaces. It seems to be most of the time on the same vlan. Does anybody have experience with this kind of problems. I was wondering if it has got something to do with QOS or queue selection As we don't have any QOS markings configured, is it possible that all traffic is using only one of the four tx queue's? I'm fairly new in configuring queue's or using QOS. Kind regards St ... View more

Dear all, Last week I installed an ASA for one of our customers with a "BASE" License. I named an INSIDE and an OUTSIDE interface The management is done over the Management interface. Now we also want to enable Tacacs to authenticate when we login on the ASA. But I'm experiencing a problem. Is it possible to authenticate aaa over the Management interface when using a "BASE" License? I can't find how to get it to work... Somebody experience with this, if it's possible afterall or does have some good doumentation? Kind rgeards Steven ... View more
