Your Mom is a Default VLAN...

The goal was to put to bed the final question that everyone asks and no one ever has a solid answer for, can you get 1.5Mbps up and 1.5Mbps down on a data T1. We have had multiple customers ask us this question recently, so I fired up two routers today to get solid results with empirical evidence to show everyone that has asked. Here's what I had; a Crisco 1720, a Juniper J2300, one laptop (WinXP) and one desktop (WinXP). Both machines are running WSFTP Server and I used the FTP client via CLI in Windows. Both T1 interfaces are configured with the IP's shown in the diagram, and encapsulation set to PPP. Using PRTG we sampled the T1 interfaces for traffic utilization via SNMP. Sampling rate was set to every 10 seconds with averaging set to 1 minute. The defaults are 60 seconds and 5 minutes respectively. The graphs below shows traffic utilization while a FTP transfer of a 593+ MB ISO to the laptop from the desktop was underway. This is to simply show traffic being transferred in...

This is our end result. An out of service (though still operational) 120 lb Cisco Catalyst 5509 chassis. This replaces a 4 legged open metal base as the original base of the table. The felt pads that are seen on the corners are supporting and protecting the glass on top of the chassis. In the middle of the table, under the glass, a glass chess board. The blades are seperated and the slot covers removed to provide space between each blade which become sliding shelves. Ultimately, this table cost us a whole $3.50. I didn't buy the glass, chess set, or the switch. Not a bad deal I'd say.
