Looking for scripting advice on how best to parse the Guest Network Pro (GNP) nvram vlan_rl value??
nvram vlan_rl value question
My setup has 3 custom GNP VLAN where the nvram setting vlan_rl has the value <1>52>0><2>53>0><3>54>0>
My understanding is that vlan_rl consists of columns of information >> SDN # (1, 2, or 3 in my case), Bridge Interface number (52, 53, or 54), and I'm not sure what the third field is for (0)
Question 1 - what is the third column of information in the nvram setting vlan_rl in each of the three SDN (0 in my case)?
Script question/advice, related to the nvram vlan_rl setting
My understanding is that the SDN number can be 1 - 2 characters, as can the Bridge Interface number, and I'm going to assume that third value can be 1 - 2 characters as well. I also understand there can be a variable number of SDN (1 - 9 or more)
Question 2 (I'm not sure how best to ask, but ..), is there some pattern matching magic that allows me to dynamically loop through the nvram vlan_rl string and pull out each SDN combination of information (SDN #, Bridge Interface #, third ??) into an array or separate variables - Something like SDN#: value, BR#: value, XX#, value??
Goal is to have a "somewhat" dynamic DNSMASQ-SDN.POSTCONF for dnsmasq customizations
Currently, my dnsmasq-sdn.postconf has hard coded SDN# references for adding different domain names (and potential other information) for each VLAN (e.g., vlan 1 = home.lan, vlan 2 = adults.lan, ...) and it's working well.
I'm just looking to enhance my scripting skills.
