I'm sure I'll be shamed for asking this question, I almost want it.
I'm the proud owner of 2 new Catalyst 3850 XS 10G SFP+. The Hardware install guide shows many examples of 3,5, switches in a stack.
What about 2 switches. If I call the data Stacking...
Hello,
I thought I posted this question but can find no evidence of it. So forgive me if I repeat myself.
I would like to find an "examples" of setting a login user to have a limited set of functionality. I searched within IoS command refreences and ...
I am trying to discover if I can "recover" a bad investment with a NAT trick. I purchased an NTP appliance and only recently discovered that it will not allow an 8-bit Sub-net mask. In and of itself, that is not bad. But, I have hundreds of devices c...
I have a core infrastructure network built on the 6506E chassis. I have the CEF720 8 port 10GE with DFC blades (WS-X6708-10GE). I have purchased 4 CVR-X2-SFP10G (V03) modules, and 2 of each of the SR and LR SFPs for them. What is happening is that an...
I had a strange occcurance with this POE switch, the C2960CPD. First of all you must know that this switch sits at the end of about 260' of cat6 copper cable on a rooftop. It is not easy to get to. So...I needed to make some possibly questionable con...
Some of the replies here don't make sense. I've configured 5 650x chassis for over 8 years, adding and changing the "switchport trunk vlan allowed 1,2,3,4,5,6-90, etc hundreds of times. I've always just pasted in the new command with the new or extra...
Excellent examples - I achieved 99% of what I'm needing on the first look at packetmischief! Thank you very much. I'm still playing with it but enabling my Help Desk techs to change a port on a vlan, cycle PoE for a port, simple diagnosis; is just wh...
Alex,I think you found the problem. I also found more detail showing that possibly I would need to upgrade my IOS from....My current IOS: 12.2(33)SXI11(fc2) (s72033_rp-IPSERVICESK9_WAN-M)Update to IOS: 12.2(33)SXJ1I think that's a newer IOS (because...
I do understand the "write mem" or "copy runn start" commands well. But what I saw was the running configuration came up after a power-cycle. I've never seen that either and if it was an anomaly then I'll dismiss it. I hope to have a serial-cat5-seri...
With the same exact topology, I was having a similar problem because I had a transparent unmanaged switch between my cisco port, and the wireless equipment (cable length > 327 feet or 100 m). The unmanaged switch could not pass maximum size valid eth...
