Configuring a Dynamic Channel
To configure a dynamic channel on all external ports from the serial connection on the
network switch module, perform the following steps:
1
Type:
#config
(config)#interface ethernet 1/7
(config-if)#lacp
(config-if)#exit
2
Repeat the commands in step 2 on ports 8, 9, and 10.
A dynamic trunk of the four uplink ports is created by LACP.
3
Repeat steps 1 and 2 for the second network switch module.
4
To save the configuration, type
#copy running-config startup-config.
5
Type
quit
or
exit
to logout of the switch console.
6
Type
~.
and press <Enter> to return to the management console.
When both network switch modules are connected to the same subnet (see Figure 1-5),
smart load balancing (SLB) can be used to "team" the LOMs to prevent spanning tree
protocol from shutting down links and to provide load balancing and failover. SLB is
configured through the Broadcom Advanced Server Program, which is on the
Dell
OpenManage Server Assistant
CD. SLB is the only LOM teaming method supported on the
PowerEdge 1655MC.
NOTE:
When you use the Broadcom drivers to configure an SLB team, the software
only performs failover on the local link (the LOM on the server module). The SLB
software cannot detect remote link failover at the uplink ports of the network switch
module. To protect against link failure, configure channeling on multiple uplink ports
on the network switch module.
NOTE:
When you use the Broadcom drivers to configure an SLB team on the server
module, failure or removal of the network switch module does not cause disruption in
network traffic. However, hot-adding of a network switch module causes temporary
disruption of network traffic while the switch is booting since SLB software tries to
balance the network traffic before the switch is ready.
