Chapter 23 Configuring PortChannels
About PortChannels
Table 23-1 compares ON and ACTIVE modes.
Configuration Guidelines and Restrictions
Cisco MDS 9000 Family switches support the following number of PortChannels per switch:
• Switches with only Generation 1 switching modules do not support F and TF PortChannels.
• Switches with Generation 1 switching modules, or a combination of Generation 1 and Generation 2
switching modules, support a maximum of 128 PortChannels. Only Generation 2 ports can be
included in the PortChannels.
• Switches with only Generation 2 switching modules or Generation 2 and Generation 3 modules
support a maximum of 256 PortChannels with 16 interfaces per PortChannel.
• A PortChannel number refers to the unique identifier for each channel group. This number ranges
from of 1 to 256.
Generation 1 PortChannel Restrictions
This section includes the restrictions on creation and addition of PortChannel members to a PortChannel
on Generation 1 hardware:
• 32-port 2-Gbps or 1-Gbps switching module
• MDS 9124 and 9134 switches
When configuring the host-optimized ports on Generation 1 hardware, the following PortChannel
guidelines apply:
Table 23-1 Channel Group Configuration Differences
ON Mode ACTIVE Mode
No protocol is exchanged. A PortChannel protocol negotiation is performed
with the peer ports.
Moves interfaces to the suspended state if its
operational values are incompatible with the
PortChannel.
Moves interfaces to the isolated state if its
operational values are incompatible with the
PortChannel.
When you add or modify a PortChannel member
port configuration, you must explicitly disable
(shut) and enable (no shut) the PortChannel
member ports at either end.
When you add or modify a PortChannel interface,
the PortChannel automatically recovers.
Port initialization is not synchronized. There is synchronized startup of all ports in a
channel across peer switches.
All misconfigurations are not detected as no
protocol is exchanged.
Consistently detect misconfigurations using a
PortChannel protocol.
Transitions misconfigured ports to the suspended
state. You must explicitly disable (shut) and
enable (no shut) the member ports at either end.
Transitions misconfigured ports to the isolated
state to correct the misconfiguration. Once you
correct the misconfiguration, the protocol ensures
automatic recovery.
This is the default mode. You must explicitly configure this mode.
