Internet slow after creating VLANs
« on: April 24, 2017, 10:51:59 PM »
So I just got VLANs working.  I only have 3.  I'm not sure what is going on.

I have a Baystack 5510-48T and a Cisco ASA 5505.

Internet communication is slow.  DNS resolution is slow or not working depending on the PC.  Typing on my linux servers is a bit slow or delayed as well.

I can provide the config for the switch.

See attached file

Hi Andrew, are you able to provide some further information about the connectivity of the switch and firewall and possibly how the internet is being connected i.e. ISP modem, any local servers, DMZ?

Sounds more like a broadcast storm/loop on the network than anything else if it is impacting CLI access on a server.
