Configuration restrictions and guidelines
When you bind physical interfaces to IRF ports, follow the restrictions in "IRF physical interface requirements."
On a physical interface bound to an IRF port, you can execute only the following commands:
Interface commands:
description.
flow-interval.
priority-flow-control.
priority-flow-control no-drop dot1p.
shutdown.
For more information about these commands, see Layer 2—LAN Switching Command Reference.
LLDP commands:
lldp admin-status.
lldp check-change-interval.
lldp enable.
lldp encapsulation snap.
lldp notification remote-change enable.
lldp tlv-enable.
For more information about these commands, see Layer 2—LAN Switching Command Reference.
MAC address table configuration commands, including the mac-address static source-check enable command.
When you configure IRF physical interfaces, follow these restrictions and guidelines:
To ensure successful forwarding of Layer 3 traffic across member devices, use the undo mac-address static source-check enable command on each IRF physical interface. For information about this command, see Layer 2—LAN Switching Command Reference.
When you execute the port service-loopback group command on an IRF physical interface, the binding between the physical interface and IRF port is removed. If an IRF port has only one IRF physical interface, do not assign the only IRF physical interface to a service loopback group to avoid IRF split. For information about the port service-loopback group command, see Layer 2—LAN Switching Command Reference.
When you execute the mirroring-group reflector-port command on an IRF physical interface, the binding between the physical interface and IRF port is removed. If an IRF port has only one IRF physical interface, do not configure the only IRF physical interface as a reflector port to avoid IRF split. For information about the mirroring-group reflector-port command, see Network Management and Monitoring Command Reference.
