I've got a bunch of SG300 Switches that are uplinked to a 2960s (some users need more ports at their desks than I have available ports at their desks). If someone has their pc plugged into the SG300 it seems every 24 hours they lose network access vi...
I'm trying to configure in-band management on a Nexus 93180. Never used a nexus before and I'm having a little trouble.With any other switch, I just put an IP on the vlan, trunk the vlans I want between switches and I'm done, I can ping.With the Nexu...
I'm noticing the output queue drops on my 3850 has huge values across virtually every port. Is there a way I can trigger some sort of EEM script to dump the packets to a wireshark file when queue drops are detected on an interface so I can see what a...
I'm looking into 10gig switches was surprised to see their shared buffers seem to be lower than 1gig models. For example, a nexus 3000 series has a smaller buffer than a 4948. Would I be correct in assuming that on a 10gig switch the amount of tra...
If my current network is setup with pim dense-mode (due to legacy reasons) on the svi of my layer 3 switch, can I connect a switch, via layer 2, that only does PIM sparse-mode?
My layer 3 switch with pim dense-mode are Cisco at the moment. I might be...
I found part of the problem I think while working with Cisco on the phone. I have unknown multicast filtering turn on (except for the uplink port) as the switch doesn't work correctly for snooping (ie. if there's a sender on the switch but not receiv...
In the case of netgear, there's a certain behavior which is problematic for us in certain cases. Might have to invesitgate d-link or just go HP next time.
I did look at the 2960-C but it was a bit expensive so couldn't do it.
I'm opening a case with...
This is exactly my problem. It's layer 2 only so why is this switch getting in the way.Another weird issue I'm seeing now if I have 2 machine elsewhere on the network which can't ping my test laptop via ipv6 (ipv4 is ok) but my laptop can ping both o...
I'm looking at a little netgear (gs108T) to compare vs the cisco.
The previous switch that was in place was an unmanaged gs108e but hopefully the 't' version is close enough.
Anyway, in the netgear it has an IPv6 address auto configuration mode set t...
Thanks for the suggestions. In this case the switches were upgraded to the newest firmware when they were unpacked and configured at command line (easier to copy/paste a few lines than mess around in the web page). Maybe I need to factory default the...
