Usage Guidelines
1. The interface and VLAN status is displayed as UP regardless of a disconnection. In such a case,
shutdown the VLAN.
a. Check the status of an interface and VLAN using:
RFController(config)#show ip interface brief
Interface IP-Address Status Protocol
vlan1 157.235.208.69(DHCP) up up
vlan3 unassigned up up
RFController(config)#
If the status of the VLAN is UP, shutdown the VLAN associated with eth1 using:
RFController(config-if)#show ip interface vlan 3 brief
Interface IP-Address Status Protocol
vlan3 unassigned up up
RFController(config-if)#shutdown
b. Check the status. Note that the VLAN has now been disassociated and the status is
DOWN.
RFController(config)#show ip interface brief
Interface IP-Address Status Protocol
vlan1 157.235.208.69(DHCP) up up
vlan3 unassigned administratively down down
RFController(config)#
2. The above example could also occur when a DHCP interface is disconnected. DHCP is not
effected though, because it runs on a virtual interface and not on a physical interface. In this
case, it is the physical interface that is disconnected not the virtual interface. When the
ethernet interface comes back up, it will restart the DHCP client on any virtual interfaces (SVIs)
of which the physical interface is a member port. This ensures if the interface was
disconnected and reconnected to a different interface, it obtains a new IP address, route,
name server, domain name etc.
