<p class=MsoNormal>I have inherited this project from a project manager who
just left with no warning. I always noticed he and I did things a bit
differently, but this one has me stumped.<br>
<br>
4 buildings, linked by fiber. CCM 6.1 and Unity. 2801s for SRST and
911 in each building. 10-15 phones per building, so total of 60 (actual
total shows 52).<br>
<br>
He has CCM and Unity in VLAN 7 in the .7 subnet.<br>
Phones are in VLAN 6 and in the .6 subnet.<br>
<br>
Doesn't this mean that for each packet in the voice stream, we will have to
traverse the router to get to the diff subnet? Is this common to do it
this way, leaving CCM and Unity in their own subnet and VLAN? If the main
router were to have an issue, all phone traffic would die, it seems.<br>
<br>
Data is in VLAN 1 in the .1 subnet.<br>
<br>
Depending on who I get in TAC, this is either fine,or troubling, since
Cisco's mgt traffic uses VLAN1. But with only about 50 users, so
figure 50 PCs, would this be an issue running the data on VLAN1?<br>
<br>
Your thoughts?<o:p></o:p></p>
