Implementing Fibre Channel

Port Modes

© Copyright Lenovo 2017
This section describes the basic elements of Fibre Channel configuration. For
examples combining these elements, see "Fibre Channel Configuration" on
page 342
Note: If you need to change the Fibre Channel configuration mode from BBI to
ISCLI, first save the configuration using the save button on the BBI. Do not use
two configuration modes at the same time.
The G8264CS has the following types of network port:
 High‐Capacity Ethernet Ports
Ports 1‐16
These 40Gb QSFP+ Ethernet ports can be configured as either four 40Gb
Ethernet ports (1, 5, 9, and 13), or as 16 10Gb Ethernet ports (1‐4, 5‐8, 5‐12, and
13‐16).
 Ethernet Ports
Ports 17‐52
These standard 10Gb SFP+ Ethernet ports provide external connectors.
 Omni Ports (External)
Ports 53‐64
These 10Gb SFP+ hybrid ports can be configured to operate either in Ethernet
mode (the default) or in Fibre Channel mode for direct connection to Fibre
Channel devices.
All Ethernet ports (including the Omni Ports by default) can carry any Ethernet
data traffic, including Fibre Channel over Ethernet (FCoE) traffic.
When configured to operate in Fibre Channel mode, Omni Ports can be used as
Fibre Channel downlinks (connected to Fibre Channel servers or storage devices)
or as uplinks (connected to the data center SAN network).
The Omni Port mode (Ethernet or Fibre Channel) can be changed only for pairs of
ports. The following port pairs share the same mode: 53‐54, 55‐56, 57‐58, 59‐60,
61‐62, 63‐64.
Paired ports need not be connected to the same device and can even be used in
different VLANs. The only required mutual attribute is the network type (Ethernet
or Fibre Channel).
Fibre Channel configuration requires that at least one pair of Omni Ports be set to
Fibre Channel mode.
The mode for Omni Port pairs or ranges can be configured using the following
privileged configuration command:
RS 8264CS(config)# [no] system port <low port>-<high port> type fc
Note: VLAN tagging is automatically enabled on any port placed in Fibre Channel
mode.
