We use a VLAN numbering scheme that maintains some similarity between ranges to make it easier to remember, but still unique - all vlans are 4 digits the first digit indicates its general function e.g. 1 for users 2 for VOIP 3 for management then the second number indicates it's site (site 1 site 2 site 3 etc. - we have 6 sites) the last two digits then are for specific locations/buildings etc.
We put use before site so it's more apparent by glancing at it what the VLAN is for which is more frequently something you need to know than what site you are at. -----Original Message----- From: Erik Auerswald [mailto:[email protected]] Sent: Saturday, September 01, 2012 1:12 PM To: Enterasys Customer Mailing List Subject: Re: [enterasys] VLANs Hi, this works fine and helps in troubleshooting (is the server's MAC address seen in the server VLAN?).
