I would need to configure the following options for avaya phones in Infoblox (gridmanager 6.8.4) DHCP option 242- Avaya IP Phones. String= MCIPADD=10.xx.xx.02,10.xx.xx.01,MCPORT=1719,VLAN=(Vlan # goes here) but I'm not sure how to configure the string options, can you please help? Thanks!

Hi Gabriel,

This is pretty straightforward. First you need to add option 242 to the data vlan as follows:

Data Management -->DHCP --> put a checkmark to the left of the data subnet --> Edit --> IPv4 DHCP Options --> scroll down to the Custom DHCP options at the bottom --> click the "+" sign and select "option 242" from the list --> enter: L2Q=1,L2QVLAN=<voice vlan #>,VLANTEST=<a number between 0 and 60) --> save and close

On the voice vlan, repeat above steps but enter: MCIPADD=<callmanager IP addr>,MCPORT=1719,HTTPSRVR=<ip addr of the HTTP server> --> save and close. If like me you are hosting the files on Infoblox in a folder on the root directory use this instead for option 242:

MCIPADD=<callmanager IP addr>,MCPORT=1719,HTTPDIR=/<folder name>/,HTTPSRVR=<Ip addr of grid member running HTTP service>
