#Switch control mac#

For example, when you select a setting by MAC address specification instead of another setting by route specification, which is also available, and execute this command, the switch is synchronized according to the setting by route specification after the setting by MAC address specification is deleted. If the both option is not specified and when another applicable setting about the switch exists, the switch is synchronized according to that setting. At the same time, performs synchronous process when the router controls the switch.

both : Deletes all applicable settings of the target switchĭeletes the settings on the router about the selected switch.

Show a List of the Switches Controlled by the Router If an Ethernet cable connecting the switch is removed, the router may decide that the switch is down earlier than the setting specified with this command. When the router receives no response packet from the switch even after sending a search packet the number of times specified in count, it decides that the switch is down.

On the contrary, when a small value is specified for time, frequency of sending a search packet is increased, but time that the router needs to identify a switch after connecting it gets shorter. When a large value is specified for time, frequency of sending a search packet is decreased, but time that the router needs to identify a switch after connecting it gets longer. Sets the time interval for sending a packet to search a switch, and the number of times to send a search packet until the router receives no response packet from the switch and decides that the switch is down.

#Switch control series#

Furthermore, as shown in the image to the right below, if the number the slaves connected in series is up to eight, the maximum number of predetermined slaves can be controlled.

As shown in the image on the left below, nine or more slaves cannot be connected to a controller serially.

Up to eight slaves (counted from the controller) can be connected to a controller serially.

Check operation before configuring a local area network (LAN) that includes another manufacturer switch.

If another manufacturer switch is on the route of switch control function communication (e.g., is inserted between the controller and the slave), the controller may not be able to control the slave correctly.

For details on the slave VLAN function, see Command Reference. The switch control function communications cannot be performed on a trunk port.

If you use VLAN on a slave, make sure to set the port that performs switch control function communications to the access port or the hybrid port.

The switch control function cannot be used on a LAN interface that has the LAN isolation function set.

Additionally, if the Ethernet cable connecting the slave is removed, the controller may decide that the switch is down earlier than the setting specified with this command.Ĭonfigure each parameter in the switch control watch interval command with applicable values that are suitable for the network environment in use. When the controller receives no response packet from the slave even after sending the specified number of search packets, it decides that the slave is down. The number of times to send a search packet can be configured in the count parameter of the switch control watch interval command. On the contrary, by decreasing the setting value, the frequency of sending a search packet is increased, but the time that the controller needs to identify a slave after connecting it gets shorter. By increasing the setting value, the frequency of sending a search packet is decreased, but the time that the controller needs to identify a slave after connecting it gets longer. The time of the transmission interval for the search packet can be configured in the time parameter of the switch control watch interval command. Once the slave receives the search packet, it notifies the controller of its existence by sending a response packet. The controller monitors the subordinate slaves by periodically transmitting a search packet.
