this is a physical rule for physical subnets, and the rule resets if you have
a switch, a bridge, or a router between physical networks. now logical networks have more rules that you have to abide by, Dan -----Original Message----- From: Jim Wallentine [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 4:32 PM To: NT System Admin Issues Subject: RE: Network Login A network should have no more than 5 segments, 4 repeaters and 3 mixing segments between any two DTEs. A mixing segment is a segment with more than 2 interfaces attached to it. A link segment is a coax UTP or fibre segment without DTE modes. When 5 segments are used the maximum length of a FOIRL (Fibre Optic Inter-Repeater Link) should be no greater than 500m. When 4 segments are used then the maximum length of FOIRL may be increases to 1000m. These rules are designed to: minimise reflections maintain acceptable attenuation limit round trip times to 575 bit times (i.e. to maintain the required collision domain) limit the interframe gap shrinkage (must be less than 49 bits -----Original Message----- From: Dewar Charles R [mailto:[EMAIL PROTECTED]] Subject: RE: Network Login I give.
