Type and Dimension: string-scalar SubNetMask The subnet mask associated with the IP address. Type and Dimension: string-scalar MACAddress The physical address of the NIC to which the virtual IP address is assigned. Note that this attribute is always local, that is, it is different for each system. Note: Use the ipconfig -all command to retrieve the physical address of a NIC. Type and Dimension: string-scalar Sample configuration IP IP_192_168_100_20 ( Address = "192.168.100.20" SubNetMask = "255.255.255.0" MACAddress @SYSTEM1 = "00-60-08-08-BA-C4" MACAddress @SYSTEM2 = "00-90-27-28-5A-7E" ) IPv6 agent The IPv6 agent is designed specifically to support Internet Protocol Version 6 (IPv6). The agent assigns a virtual IPv6 address to the network interface card (NIC), monitors the IPv6 address, and removes it. The agent also monitors the associated IPv6 prefix on the NIC. You can use this agent when you want to monitor a single IPv6 address on a single adapter. The IPv6 setting on the interface must be enabled with a physical (or administrative) base IPv6 address before you can assign it a virtual IPv6 address.

Network agents IPv6 agent 57 The IPv6 agent currently supports the following types of IPv6 addresses: ■ ■ Unicast addresses Only Global Unicast and Unique Local Unicast addresses are supported. Automatic configuration Only Stateless IPv6 address configuration is supported. Stateless addresses are based on the information received from the routers configured on the network. Dependency The IPv6 resource depends on the NIC resource. Agent functions online monitor offline clean Retrieves the IPv6 address from the configured attributes, verifies that the IPv6 address is unique and not in use already and then assigns the address to the NIC. Retrieves the IPv6 address from the configured resource and verifies that the IPv6 address is assigned to the NIC. Removes the IPv6 address assigned to the NIC. Removes the IPv6 address assigned to the NIC. State definitions ONLINE OFFLINE UNKNOWN FAULTED Indicates the specified virtual IPv6 address is assigned to the NIC. Indicates the specified virtual IPv6 address is not assigned to the NIC. Indicates the agent encountered errors while monitoring the IPv6 resource. This may be due to an invalid or incorrect configuration, or an unsupported IPv6 address type. Indicates that the agent was unable to bring the IPv6 address online. This may be because the IPv6 address was removed out of VCS control, or the IPv6 address is already online on the network.

IPv6 agent<br />

The IPv6 agent is designed specifically to support Internet Protocol Version 6<br />

(IPv6). The agent assigns a virtual IPv6 address to the network interface card<br />

(NIC), monitors the IPv6 address, and removes it. The agent also monitors the<br />

associated IPv6 prefix on the NIC.<br />

You can use this agent when you want to monitor a single IPv6 address on a single<br />

adapter. The IPv6 setting on the interface must be enabled with a physical (or<br />

administrative) base IPv6 address before you can assign it a virtual IPv6 address.
