Link Aggregation; Link Aggregation Layer 3 Configuration - Dell Force10 S2410-01-10GE-24P Configuration Manual

Link Aggregation

A Link Aggregation Group (LAG) (also called a port channel) allows multiple physical links between two
end-points to be treated as a single logical link. All of the physical links in a given LAG must operate in
full-duplex mode at the same speed.
A LAG will be treated by management functions as if it were a single physical port. It may be included in
a VLAN. More than one LAG may be configured for a given switch.
For more details on LAGs, see

Link Aggregation Layer 3 Configuration

This section provides an example of configuring the S-Series to support a routed Link Aggregation Group
(LAG). SFTOS does not support directly assigning an IP address to a LAG, so the workaround is to assign
the LAG ports to a VLAN that has an IP address.
In summary, as introduced in
1. Configure a LAG.
2. Configure a Layer 3 VLAN.
3. Associate ports with the VLAN.
4. Associate those ports with the LAG.
5. Enable the LAG.
In detail, the command sequence is:
1. Create and enable all LAGs. Link trap notification will be enabled by default.
Figure 17-251. Example of Creating a LAG
R1 #config
R1 (Config)#interface port-channel 10
R1 (conf-if-po-10)#channel-member 1/0/10-1/0/11
R1 (Config)#exit
R1 (Config)#port-channel enable all
2. Configure the Layer 3 VLAN and add the LAG to it.
Figure 17-252. Example of Creating a Layer 3 VLAN
R1 (Config)#interface vlan 100
R1 (Conf-if-vl-100)#ip address 100.0.0.1 255.255.255.252
R1 (Conf-if-vl-100)#untagged port-channel 10
R1 (Conf-if-vl-100)#exit
R1 (Config)#
3. Use the show vlan id
inspect the interfaces.
