DES-3226S Layer 2 Fast Ethernet Switch User's Guide To change MAC Notification settings for a port or a group of ports on the same Switch, select the first (lowest numbered) port from the list and click the Edit button, a separate menu will appear. Figure 6 - 67. MAC Notification Port Settings - Edit Configure the following MAC notification global settings: Parameter Description Port State Configure Ports from __ to __ Select the port or lowest number of the group of ports being configured. Enable or Disable MAC notification for the port from the pull-down menu. A consecutive group of ports may be configured starting with the selected port. Link Aggregation Link aggregation allows several ports to be grouped together and to act as a single link. This gives a bandwidth that is a multiple of a single link's bandwidth. Link aggregation is most commonly used to link a bandwidth intensive network device or devices - such as a server - to the backbone of a network. The Switch allows the creation of up to 6 link aggregation groups, each group consisting of up of up to 8 links (ports). The aggregated links must be contiguous (they must have sequential port numbers) except the two (optional) Gigabit ports - which can only belong to a single link aggregation group. A link aggregation group may not cross an 8-port boundary, starting with port 1 (a group may not contain ports 8 and 9, for example) and all of the ports in the group must be members of the same VLAN. Further, the aggregated links must all be of the same speed and should be configured as full-duplex. The configuration of the lowest numbered port in the group becomes the configuration for all of the ports in the aggregation group. This port is called the Master Port of the group, and all configuration options - including the VLAN configuration - that can be applied to the Master Port are applied to the entire link aggregation group. Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the network traffic to be directed to the remaining links in the group. The Spanning Tree Protocol will treat a link aggregation group as a single link, on the Switch level. On the port level, the STP will use the port parameters of the Master Port in the calculation of port cost and in determining the state of the link aggregation group. If two redundant link aggregation groups are configured on the Switch, STP will block one entire group - in the same way STP will block a single port that has a redundant link. 89

To change MAC Notification settings for a port or a group of ports on the same Switch, select the first (lowest numbered) port
from the list and click the Edit button, a separate menu will appear.
Figure 6 - 67. MAC Notification Port Settings - Edit
Configure the following MAC notification global settings:
Parameter
Description
Port
Select the port or lowest number of the group of ports being configured.
State
Enable or Disable MAC notification for the port from the pull-down menu.
Configure Ports from __ to __
A consecutive group of ports may be configured starting with the selected port.
Link Aggregation
Link aggregation allows several ports to be grouped together and to act as a single link. This gives a bandwidth that is a
multiple of a single link’s bandwidth.
Link aggregation is most commonly used to link a bandwidth intensive network device or devices – such as a server – to the
backbone of a network.
The Switch allows the creation of up to 6 link aggregation groups, each group consisting of up of up to 8 links (ports). The
aggregated links must be contiguous (they must have sequential port numbers) except the two (optional) Gigabit ports – which
can only belong to a single link aggregation group. A link aggregation group may not cross an 8-port boundary, starting with
port 1 (a group may not contain ports 8 and 9, for example) and all of the ports in the group must be members of the same
VLAN.
Further, the aggregated links must all be of the same speed and should be configured as full-duplex.
The configuration of the lowest numbered port in the group becomes the configuration for all of the ports in the aggregation
group. This port is called the Master Port of the group, and all configuration options – including the VLAN configuration – that
can be applied to the Master Port are applied to the entire link aggregation group.
Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the
network traffic to be directed to the remaining links in the group.
The Spanning Tree Protocol will treat a link aggregation group as a single link, on the Switch level. On the port level, the STP
will use the port parameters of the Master Port in the calculation of port cost and in determining the state of the link
aggregation group. If two redundant link aggregation groups are configured on the Switch, STP will block one entire group –
in the same way STP will block a single port that has a redundant link.
