DHCP Option 156 on ASA5505 v8.21 for Shoretel Phones
Posted on 2009-05-07
I have an ASA5505 running 8.21 but I am having trouble setting the option 156 on the ASA for the Shoretel phones. I have done this in the past on Cisco routers and numerous other types of devices. I was assuming the ASA would be similiar but it appears to be different. In the past I have used dhcpd option 156 ascii "ftpservers=192.168.2.1 layer2tagging=1 vlanid=2", but when I try this one the ASA (both in the CLI and the ASDM v6.21) I get an error - Too many ASCII strings from the CLI, and ASCII Data cannot contain spaces from the ASDM - which is why you use the quotes (at least in the Cisco routers). I have searched the forums and I have seen other people with this same issue and everyone directs them to some old link about a Cisco router assuming they are the same...they aren't Let me know if anyone has any ideas...and thank you for your help.
