The switch's administrative IP address. The switch may automatically discover a value for this object using the BootStrap protocol (BOOTP). The object value is also duplicated in the MIB-II ipAddrTable. The following applies to switches operating with firmware version smaller than 6.00: When VLANs are present, The switch may be configured with up to 4 administrative IP addresses, one per VLAN. This object, in this case, configures the IP address for the first VLAN. See the object vlanTable for how to configure the other IP addresses. Assigning multiple VLAN IP addresses is only necessary if the VLANs in use represent separate physical IP subnets. This allows a management station residing on a VLAN to directly manage the switch without the need for an intervening router/gateway. A write to this object will take effect immediately, replacing the previous address, if any.
