Cat 3920 ip address
Typically, there are two methods for configuring a switch for IP management:
One way is to assign the management interface of the switch itself to a particular VLAN and then giving it an IP address relevant for that VLAN.
The other method is to assign a management IP address for the switch in each VLAN that you want to manage the switch from. If you do not assign an IP address for the switch in a particular VLAN, you will not be able to manage the switch from that particular VLAN. If you assign an IP address to the switch in only one VLAN, it effectively accomplishes the same thing as the option above.
The Cat. 5K uses the former method, the 3920 the latter. So in your case, when you assign an IP address to the TrBRF that is the parent of the TrCRF containing the port your router is connected to, that IP address effectively IS the 3920 itself on that subnet.
