We need to test config file against errors

• Someone can try to use "yes" to turn on a boolean parameter which needs "on"
• Someone can wrong type a parameter
• Someone can write an invalid parameter
• Someone can write an invalid IP address / CIDR

As tested on a physical switch, when setting an interface on trunk mode, we need to call: switchport trunk encapsulation dot1q

co-dr2.staging(config-if)#switchport mode trunk
Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.
co-dr2.staging(config-if)#switchport trunk encapsulation dot1q
co-dr2.staging(config-if)#switchport mode trunk
co-dr2.

In your readme for SNMPv3 you have the key listed as:

LLD.py["-h", {HOST.CONN}, "-v3", "-u{$SNMP_USER}", "-l{$SNMP_LEVEL}", "-aSHA", "-A{$SNMP_AUTH}", "-xAES", "-X{$SNMP_PRIV}", "-mi", "{#PEERADDR}", "-m", "{#PREFXTBL}", "{#ADDRTYPE}", "{#ASNUM}"]

I had to change the format to get this working:

LLD.py["-h", {HOST.CONN}, "-v", "3",  "-l", "authPriv", "-u", "{$SNMP_SECURITY}", "-

Description

For SCaLE19x, I'd like to set up a test for IPv4 as a service on a V6-Only SSID/VLAN.

Acceptance Criteria

Ideally, users won't see any meaningful difference.

I'd like to also test this mechanism on the Registration VLAN so that we can run the VLAN IPv6-Only and still get to the degraded IPv4-only PayPal service it currently depends on.
