(JC102A/JC102B)
•
5820X-24XG-SFP+
TAA-compliant Switch

The 24 fixed SFP+ ports on the
front panel
No location restriction for the physical
ports of an IRF port.
MAD
•
Configure at least one MAD mechanism for prompt IRF split detection and IRF fabric recovery.
•
If LACP MAD or ARP MAD runs between two IRF fabrics, assign each fabric a unique IRF
domain ID. (For BFD MAD, this task is optional.)
•
To exclude a port from the shutdown action that is executed when an IRF fabric transits to the
Recovery state, use the
mad exclude interface
command. To bring up a port after the IRF
fabric transits to the Recovery state, you must use the
mad restore
command instead of the
undo shutdown
command.
FIPS mode requirement
To form an IRF fabric, all member devices must use the same FIPS mode setting (configurable with
the
fips mode enable
command). For more information about FIPS mode, see
Security
Configuration Guide
.
Other configuration guidelines
•
Strictly follow the IRF fabric setup procedure described in "
Setup and configuration task list
plan the IRF fabric, identify IRF physical ports, connect IRF member switches, and configure
basic settings.
•
Assign each member a unique IRF member ID to make sure they can merge. You must reboot
the members to validate the IRF member ID settings.
•
Assign the highest member priority to the device you want to use as the master.
•
Before removing an interface card that has physical IRF ports in an IRF fabric, remove the IRF
connection cables, or use the
shutdown
command to shut down the IRF physical ports.
•
If a subordinate switch uses the same next-startup configuration file name as the master switch,
the file might be overwritten depending on your configuration file management settings. To
continue to use the configuration file after removing the switch from the IRF fabric, back up the
file before setting up the IRF fabric.
•
Save any configuration you have made to the startup configuration file before rebooting the IRF
member devices.
•
The Layer 3 Ethernet port in this book refers to an Ethernet port that can perform IP routing and
inter-VLAN routing. You can set an Ethernet port as a Layer 3 Ethernet interface by using the
port link-mode route
command (see
Layer 2—LAN Switching Configuration Guide
).
