CONFIGURATION GUIDE
Configuring an iSCSI SAN Using Brocade FCX Switches
17
NOTE:
If you plan to use the the 10 Gbps SFP+ front-facing ports on a Brocade FCX 648-E for link aggregation, you
must first disable stacking on those ports. Use the
show stack
command to verify if stacking is enabled on those
ports.
NOTE:
Brocade recommends that you remove the cables from the ports you plan to enable for dynamic link
aggregation prior to configuring.
To configure link aggregation on a Brocade FCX 648-S using the front-facing 10G uplink ports, enter the
following commands on each switch involved:
FCX648S Switch(config)#
interface ethernet 1/3/1
FCX648S Switch(config-if-e10000-1/3/1)#
link-aggregate active
FCX648S Switch(config)#
interface ethernet 1/3/2
FCX648S Switch(config-if-e10000-1/3/2)#)#
link-aggregate active
Syntax: interface ethernet
<stack-unit/slotnum/portnum>
link-aggregate active
To configure link aggregation on a Brocade FCX 648-E using the front-facing 10G uplink ports, enter the
following commands for each switch involved:
FCX648-E Switch(config)#
interface ethernet 1/2/3
FCX648-E Switch(config-if-e10000-1/2/3)#
link-aggregate active
FCX648-E Switch(config)#
interface ethernet 1/2/4
FCX648-E Switch(config-if-e10000-1/2/4)#)#
link-aggregate active
Syntax: interface ethernet
<stack-unit/slotnum/portnum>
link-aggregate active
Figure 5.
Redundant cabling example using two Brocade FCX switches, no stacking.
The Brocade FCXs in Figure 5 are connected via link aggregations on the 10G uplink ports. The active and
passive controllers on each array have a link to both switches. Initiators can also be provided redundant
connections to the iSCSI SAN using multiple NICs or a dual-port NIC.
