<br>Interesting. I thought somehow you programmed additional information into the switch and CER read that via SNMP. I guess all it reads via SNMP is the phone that is attached to the port.<div><br><br>---<br>Lelio Fulgenzi, B.A.<br>

<br>using CER here. Each switchport has its own location, so its not a problem for example to have part of the switch service one floor/area, and the other part service a difference location. It does mean that your network support staff must be aware that if they change where a port is patched to, a change may also need to be made to the CER configuration for that port.<div>
<br></div><div>Would be fantastic if CER were smart enough to read in the switchport description and glean the ERL from that. <br><br><div class="gmail_quote">On Thu, Sep 24, 2009 at 1:53 PM, Lelio Fulgenzi <span dir="ltr"><<a href="mailto:lelio@uoguelph.ca" target="_blank">lelio@uoguelph.ca</a>></span> wrote:<br>

In our current layer 1 model, we install a switch stack in a particular space which services both horizontal and vertical space. For example, a switch stack in one corner of the building could service half the desks on each of four floors, and a switch stack in another corner of the building could service the other half on each of four floors.<br>
<br>How will that complicate things going forward if we want to do E911?<br><br>---<br><font color="#888888">Lelio Fulgenzi, B.A.<br>Senior Analyst (CCS) * University of Guelph * Guelph, Ontario N1G 2W1<br>(519) 824-4120 x56354 (519) 767-1060 FAX (JNHN)<br>
