I wanted my second switch (the one connected to g0/0/1) to obtain a management IP (10.4.1.0/24) from VLAN2. Analogous to how one would connect a trunk port on one switch to another trunk on a different switch and pass VLAN info and use the native VLA...

I'm trying to get the 192.168.10.0/24 subnet translated to 10.4.20.253. (Is working as of now) VLAN 2 (10.4.1.0/24) is the native that trunks the VLANS and I'm attempting to give the switch a management IP from that pool via DHCP.
