Abstract

A disclosed switch includes: plural ports; a first unit that applies profile associated with identification data to a port of the plural ports, upon receiving a message, which includes the identification data of profile relating to the another apparatus, through a first link in a situation that another apparatus connected to the port through the first link is connected to another switch through a second link and the first and second link are virtually integrated; a second unit that generates information including a first identifier of the profile and a second identifier of the first and second links virtually integrated, and transmits the information to the another switch, upon receiving the message; and a third unit that applies profile associated with a third identifier to the port when that profile has not been applied, upon receiving the third identifier of the profile and the second identifier from the another switch.

Claims

1. A switch, comprising:

a plurality of ports;

a memory; and

a processor configured to use the memory and execute a process, the process comprising;

first applying profile data associated with identification data to a first port of the plurality of ports, upon receiving a predetermined message through a first link in a situation that another apparatus connected to the first port through the first link is connected to another switch through a second link and the first link and the second link are virtually integrated, wherein the predetermined message includes the identification data of profile data relating to the another apparatus;

generating a first registration notification that includes a first identifier of the profile data and a second identifier for identifying the first link and the second link which are virtually integrated, upon receiving the predetermined message;

transmitting the first registration notification to at least the another switch; and

second applying profile data associated with a third identifier to the first port when the profile data associated with the third identifier has not been applied to the first port, upon receiving a second registration notification, which includes the third identifier of the profile data and the second identifier for identifying the first link and the second link which are virtually integrated, from the another switch.

2. The switch as set forth in claim 1, wherein the predetermined message is a message broadcasted in order to obtain addresses of other apparatuses, the identification data is a transmission source address of the predetermined message, and

the first applying comprises:

suspending release of application of the profile data associated with the identification data for a predetermined time period, upon receiving a second predetermined message that includes the identification data of profile data relating to the another apparatus from a port other than the first port of the plurality of the ports; and

releasing the application of the profile data associated with the identification data, upon not receiving the first registration notification that includes the first identifier and the second identifier within the predetermined time period.

3. The switch as set forth in claim 2, wherein the profile data associated with the another apparatus data is kept applied upon receiving the first registration notification that includes the first identifier and the second identifier within the predetermined time period.

4. The switch as set forth in claim 1, wherein the predetermined message is a first notification transmitted with respect to activation of a virtual machine or a physical machine, a second notification for confirmation of a state is transmitted, from the another apparatus, with respect to the first notification, and

the first applying comprises:

setting a predetermined grace period in association with the profile data associated with the identification data; and

resetting measurement of the predetermined grace period, upon receiving the second notification.

5. The switch as set forth in claim 4, wherein the second applying comprises:

resetting measurement of the predetermined grace period, upon receiving the first registration notification that includes the first identifier and the second identifier from the another switch.

6. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a process, the process comprising:

first applying profile data associated with identification data to a first port of a plurality of ports, upon receiving a predetermined message through a first link in a situation that another apparatus connected to the first port through the first link is connected to another switch through a second link and the first link and the second link are virtually integrated, wherein the predetermined message includes the identification data of profile data relating to the another apparatus;

generating a first registration notification that includes a first identifier of the profile data and a second identifier for identifying the first link and the second link which are virtually integrated, upon receiving the predetermined message;

transmitting the first registration notification to at least the another switch; and

second applying profile data associated with a third identifier to the first port when the profile data associated with the third identifier has not been applied to the first port, upon receiving a second registration notification, which includes the third identifier of the profile data and the second identifier for identifying the first link and the second link which are virtually integrated, from the another switch.

7. A setting method, comprising:

first applying, by a processor, profile data associated with identification data to a first port of a plurality of ports, upon receiving a predetermined message through a first link in a situation that another apparatus connected to the first port through the first link is connected to another switch through a second link and the first link and the second link are virtually integrated, wherein the predetermined message includes the identification data of profile data relating to the another apparatus;

generating, by the processor, a first registration notification that includes a first identifier of the profile data and a second identifier for identifying the first link and the second link which are virtually integrated, upon receiving the predetermined message;

transmitting, by the processor, the first registration notification to at least the another switch; and

second applying, by the processor, profile data associated with a third identifier to the first port when the profile data associated with the third identifier has not been applied to the first port, upon receiving a second registration notification, which includes the third identifier of the profile data and the second identifier for identifying the first link and the second link which are virtually integrated, from the another switch.
