Configuring 32-port Switching Modules and Host-Optimized Ports
The 32-port 1/2-Gbps switching module contains 8 port groups of 4 ports each. When configuring these
modules or the host-optimized ports in the Cisco 9100 Series, the following guidelines apply:
•
•
In the Cisco MDS 9100 Series, the left most groups of ports outlined in white (4 ports in the 9120 switch
and 8 ports in the 9140 switch) are full line rate like the 16-port switching module. The other ports (16
ports in the 9120 switch and 32 ports in the 9140 switch) are host-optimized like the 32-port switching
module. Each group of 4 host-optimized ports have the same rules as for the 32-port switching module.
Managing Physical Attributes for a Port
To configure beacon mode and monitor physical attributes for ports from the Fabric Manager, choose
Physical Interfaces from the menu tree and click the Physical tab.
To configure beacon mode and monitor physical attributes for ports from the Device Manager, choose
the type of port from the Interface menu and click the Physical tab.

PortChannel C aggregates three links. Two links are on the same switching module at each end,
while one is connected to a different switching module on switch 2.

PortChannel Flexibility
Switch 1
Any (or all) full line rate port(s) in the Cisco MDS 9100 Series can be included in a PortChannel.
The host-optimized ports in the Cisco MDS 9100 Series are subject to same PortChannel rules as
32-port switching modules--only the first port of each group of 4 ports is included in a PortChannel.
You can configure only the first port in each 4- port group (for example, the first port in ports
–
1-4, the fifth port in ports 5-8 and so on) as an E port. If the first port in the group is configured
as a PortChannel, the other three ports in each group (ports 2-4, 6-8 and so on) are not usable
and remain in the shutdown state.
If any of the other three ports are configured in a no shutdown state, you cannot configure the
–
first port as a PortChannel. The other three ports continue to remain in a no shutdown state.
