1. Read Cisco devices from a file I create: 

host1.domain.com
host2.domain.com
host3.domain.com

2. For each device in this list do snmpgets to get:

a. a port description for each port (devices will have 16, 24, 48 or more ports)
b. the oper status for each port
c. the admin status for each port
d. the last change status for each port

3. I want the output to be in a CSV format so the file can be opened with Excel

4. The variables I will be polling are:

a. snmpwalk interfaces.ifTable.ifEntry.ifDescr public $host
b. snmpwalk interfaces.ifTable.ifEntry.ifOperStatus public $host
c. snmpwalk interfaces.ifTable.ifEntry.ifAdminStatus public $host
d. snmpwalk interfaces.ifTable.ifEntry.ifLastChange public $host

5. Here is a sample snmpwalk for each variable above.  

a. johnsonr@nmscrme01 >  snmpwalk 10.245.159.57 public interfaces.ifTable.ifEntry.ifDescr         
interfaces.ifTable.ifEntry.ifDescr.1 = FastEthernet0/1
interfaces.ifTable.ifEntry.ifDescr.2 = FastEthernet0/2
interfaces.ifTable.ifEntry.ifDescr.3 = FastEthernet0/3
.....

b. johnsonr@nmscrme01 >  snmpwalk 10.245.159.57 public interfaces.ifTable.ifEntry.ifOperStatus
interfaces.ifTable.ifEntry.ifOperStatus.1 = up(2)
interfaces.ifTable.ifEntry.ifOperStatus.2 = up(2)
interfaces.ifTable.ifEntry.ifOperStatus.3 = down(2)
.....

c. johnsonr@nmscrme01 >  snmpwalk 10.245.159.57 public interfaces.ifTable.ifEntry.ifAdminStatus
interfaces.ifTable.ifEntry.ifAdminStatus.1 = up(2)
interfaces.ifTable.ifEntry.ifAdminStatus.2 = up(2)
interfaces.ifTable.ifEntry.ifAdminStatus.3 = down(2)
.....

d. johnsonr@nmscrme01 >  snmpwalk 10.245.159.57 public interfaces.ifTable.ifEntry.ifLastChange 
interfaces.ifTable.ifEntry.ifLastChange.1 = Timeticks: (628809469) 72 days, 18:41:34.69
interfaces.ifTable.ifEntry.ifLastChange.2 = Timeticks: (2297919248) 265 days, 23:06:32.48
interfaces.ifTable.ifEntry.ifLastChange.3 = Timeticks: (5370) 0:00:53.70
.....

My goal is this, open the csv file using Excel so the output will look something like this:

FastEthernet0/1	up(2)	up(2)	Timeticks: (628809469) 72 days, 18:41:34.69
FastEthernet0/2	up(2)	up(2)	Timeticks: (2297919248) 265 days, 23:06:32.48
FastEthernet0/3	down(2)	down(2)	Timeticks: (5370) 0:00:53.70


Of course it would like this before opening it as a .csv

FastEthernet0/1,up(2),up(2),Timeticks: (628809469) 72 days, 18:41:34.69
FastEthernet0/2,up(2),up(2),Timeticks: (2297919248) 265 days, 23:06:32.48
FastEthernet0/3,down(2),down(2),Timeticks: (5370) 0:00:53.70
