Trying to understand why connectivity response would change from a simple shut no shut on a few interfaces on a 2960 24 port switch.
Summary:
Three Win 7 computers serving cash register functions are connected to interfaces on a 2960. Cable lengths measured by a Fluke are 184 ft, 194 ft, and 200 ft. Connections are directly back to the switch. Egress devices are an ASA 5505 and ISP modem.
Cashiers launch an RDP session to connect to vendor servers, I think at Peak 10, and then to run sales software. The RDP experience is set to 2-16MB high latency.
For PCI compliance cash register traffic is segregated off to a VLAN and restricted to a handful of Internet addresses.
Until recently I could not figure out why RDP sessions were taking 1-2 minutes before even getting a server response.
This was on all three computers on the same VLAN.
I issued shut/no shut commands on one of the 2060 interfaces and afterwards the connection time to get an RDP response dropped to around 10-20 seconds. I did the same on the other two switch interfaces and got the same results, a huge improvement.
I would say that possible there's something going on at the switch level, but I see the same problem in sever all stores.
Each store is configured the same way for virtual and physical connectivity.
Any thoughts are much appreciated.
Thanks!
