Allied Telesis AT-9724TS Forwarding & Filtering Unicast Forwarding, Vlan ID VID, MAC Address

		0 (auto) – Setting 0 for the external cost will automatically set the speed for forwarding packets to the specified
		port(s) in the list for optimal efficiency. Default port cost: 100Mbps port = 200000. Gigabit port = 20000.
		value 1-200000000– Define a value between 1 and 200000000 to determine the external cost.The lower the
	Hello Time	number, the greater the probability the port will be chosen to forward packets.
		The time interval between the transmission of configuration messages by the designated port, to other devices
		on the bridged LAN, thus stating that the Switch is still functioning.The user may choose a time between 1 and
	Migration	10 seconds.The default is 2 seconds.This field is only operable when the Switch is enabled for MSTP.
		Setting this parameter as "yes" will set the ports to send out BDPU packets to other bridges, requesting
		information on their STP setting If the Switch is configured for RSTP, the port will be capable to migrate from
		802.1d STP to 802.1w RSTP. If the Switch is configured for MSTP, the port is capable of migrating from 802.1d
		STP to 802.1s MSTP. RSTP and MSTP can coexist with standard STP, however the benefits of RSTP and MSTP
		are not realized on a port where an 802.1d network connects to an 802.1w or 802.1s enabled network.
		Migration should be set as yes on ports connected to network stations or segments that are capable of being
	Edge	upgraded to 802.1w RSTP or 802.1s MSTP on all or some portion of the segment.
		Choosing the true parameter designates the port as an edge port. Edge ports cannot create loops, however an
		edge port can lose edge port status if a topology change creates a potential for a loop. An edge port normally
		should not receive BPDU packets. If a BPDU packet is received, it automatically loses edge port status.
	P2P	Choosing the false parameter indicates that the port does not have edge port status.
		Choosing the True parameter indicates a point-to-point (P2P) shared link. P2P ports are similar to edge ports,
		however they are restricted in that a P2P port must operate in full-duplex. Like edge ports, P2P ports transition
		to a forwarding state rapidly thus benefiting from RSTP. A p2p value of false indicates that the port cannot have
		p2p status. Auto allows the port to have p2p status whenever possible and operate as if the p2p status were
		true. If the port cannot maintain this status, (for example if the port is forced to half-duplex operation) the p2p
	State	status changes to operate as if the p2p value were False.The default setting for this parameter is True.
		This drop-down menu allows you to enable or disable STP for the selected group of ports.The default is
		Enabled.

Unicast Forwarding

Open the Forwarding & Filtering folder in the Configuration menu and click on the Unicast Forwarding link.This will open the Setup Static Unicast Forwarding Table, as shown below:

Figure 6- 34. Setup Static Unicast Forwarding Table and Static Unicast Forwarding Table window

To add or edit an entry, define the following parameters and then click Add/Modify:

Parameter	Description
VLAN ID (VID)	The VLAN ID number of the VLAN on which the above Unicast MAC address resides.
MAC Address	The MAC address to which packets will be statically forwarded.This must be a unicast MAC address.
Unit	Choose the Switch ID number of the Switch in the switch stack to be modified.
Port	Allows the selection of the port number on which the MAC address entered above resides.
