RE: Sniffer on a Frame line... [7:2253]
Frame over serial? (T1/Ds1/Ds3) They would have to plug into a Network analyzer with a compatible interface, not a hub. Most hardware network analyzers have pass-through connections that let you plug through the analyzer to the router.

The RJ45 connection between the DSU/CSU and the wall jack. Would putting a hub between the two work? Then I could place a sniffer on the hub. -Original Message- From: Hire, Ejay [mailto:[EMAIL PROTECTED]] Sent: Friday, April 27, 2001 11:00 AM To: [EMAIL PROTECTED] Subject: RE: Sniffer on a Frame line...

RE: Sniffer on a Frame line... [7:2253]
If your sniffer is a WAN sniffer, you could use a V35 Y cable between the CSU and the router. If it is a LAN sniffer, you will probably have to plug it into the hub or switch that your router connects to. -Original Message- From: Rizzo Damian [mailto:[EMAIL PROTECTED]] Sent: Friday, April 27, 2001 11:25 AM To: [EMAIL PROTECTED] Subject: RE: Sniffer on a Frame line...

RE: Sniffer on a Frame line... [7:2253]
RJ45 does not equal Ethernet. Are you thinking of placing an ethernet hub there? If so, you have completely incompatible physical layers to begin with. A T-1 signal from a csu/dsu or an NIU is going to wreak all sorts of havoc on an ethernet hub, most likely. You also have completely different datalink layers, so you can't expect an ethernet sniffer to have the slightest idea what is going on inside a frame relay frame on a DS1. This not unlike asking "Can I connect a regular phone to an ethernet hub and listen in on a VoIP call?" Completely incompatible technologies. You'd have to find a hardware sniffer designed for frame relay. HTH, John >>> "Rizzo Damian" 4/27/01 9:24:53 AM >>> The RJ45 connection between the DSU/CSU and the wall jack.

RE: Sniffer on a Frame line... [7:2253]
There are CSU/DSU's that will also act as a sniffer for frame-relay ckts. They usually are ungodly expensive unless your carrier provides it for you. Visual Networks comes to mind as as a manufacturer of these little toys. The amount you can capture is dependent upon the amount of mem in the csu. Not the best one out there but works very well.
