Hello,<br>
<br>
I have ISC DHCP V4 configured for my Nortel IP Phones. Soon we are
adding Avaya 96xx series phones which require a different DHCP
configuration and I could use some assistance how to best handle
that. Both types of phones will share the same network and address
range.<br>
<br>
My current configuration:<br>
<br>
<tt>option space Nortel;</tt><tt><br>
</tt><tt>option Nortel.data code 128 = string;</tt><tt><br>
</tt><tt><br>
</tt><tt>class "ipphones" {</tt><tt><br>
</tt><tt> match if substring(option vendor-class-identifier,0,14) =
4e:6f:72:74:65:6c:2d:69:32:30:30:34:2d:41;</tt><tt><br>
</tt><tt>}</tt><tt><br>
</tt><tt><br>
</tt><tt>shared-network Voice1 {</tt><tt><br>
</tt><tt> subnet 172.25.5.0 netmask 255.255.255.0 {</tt><tt><br>
</tt><tt> option routers 172.25.5.5;</tt><tt><br>
</tt><tt> option broadcast-address 172.25.5.255;</tt><tt><br>
</tt><tt> option subnet-mask 255.255.255.0;</tt><tt><br>
</tt><tt> allow unknown-clients;</tt><tt><br>
</tt><tt> default-lease-time 86400;</tt><tt><br>
</tt><tt> max-lease-time 86400;</tt><tt><br>
</tt><tt> pool {</tt><tt><br>
</tt><tt> vendor-option-space Nortel;</tt><tt><br>
</tt><tt> option Nortel.data
"Nortel-i2004-A,172.25.10.203:4100,1,5;172.25.10.203:4100,1,5;172.25.47.22:5000.";</tt><tt><br>
</tt><tt> range 172.25.5.128 172.25.5.254;</tt><tt><br>
</tt><tt> allow members of "ipphones";</tt><tt><br>
</tt><tt> }</tt><tt><br>
</tt><tt> }</tt><tt><br>
</tt><tt>}</tt><br>
<br>
I want to add the following new class and options for the 96xx
series phones but I'm not sure how best to merge the two? Do I add
the Avaya option statement into the subnet pool declaration above or
move the Nortel option statement out of the pool declaration and
into the class "iphones". I want DHCP to respond with only the
correct option matched to the phone. <br>
<br>
<tt>option space AVAYA_PHONE;</tt><tt><br>
</tt><tt> option AVAYA_PHONE.242 code 242 = text; #Used by 96xx
and newer hardware</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt>class "avaya-phones" {</tt><tt><br>
</tt><tt> match if substring (option vendor-class-identifier, 0,
13) = "ccp.avaya.com" ;</tt><tt><br>
</tt><tt> option </tt><tt><tt>AVAYA_PHONE.242</tt>
"MCIPADD=172.25.43.18,172.25.43.19,MCPORT=1719,TLSSRVR=172.25.43.80,HTTPSRVR=172.25.43.80,DIR=sip,TLSDIR=sip,HTTPDIR=sip"</tt><tt><br>
