24port group interfaceUse port group interface to bind a physical port to an IRF port.Use undo port group interface to remove the binding of a physical port and an IRF port.Syntaxport group interface interface-type interface-number [ mode { enhanced | normal } ]undo port group interface interface-nameDefaultNo physical ports are bound to any IRF port.ViewsIRF port viewDefault command level3: Manage levelParametersinterface-type interface-number: Specifies a physical port by its type and number.interface-name: Specifies a physical port in the interface-typeinterface-number format. No space isallowed between the interface-type and interface-number arguments.mode: Sets the operating mode of the physical IRF port. If no mode is set, the port operates in enhancedmode. The operating mode set in this command takes effect only when the physical port is operating asan IRF physical port.• enhanced—Sets the physical IRF port to operate in enhanced mode. To support MPLS L2VPN orVPLS, use the enhanced mode.• normal—Sets the physical IRF port to operate in normal mode.Usage guidelinesBefore binding a physical port to an IRF port or removing their binding, use the shutdown command toshut down the physical port.The S5800 and S5820X switches support up to four physical ports for an IRF port.Make sure the physical ports at both ends of an IRF link are using the same operating mode. For anaggregate IRF link, H3C recommends configuring the same operating mode for all physical IRF ports atboth ends.The system does not automatically remove the binding between a physical port and an IRF port, even ifthe IRF link has been lost, for example, because the interface card holding the physical port is removed.To remove the binding, use the undo port group interface command.Examples# Bind Ten-GigabitEthernet 3/0/25 to IRF port 3/1. system-view[Sysname] interface ten-gigabitethernet 3/0/25[Sysname-Ten-GigabitEthernet3/0/25] shutdown[Sysname-Ten-GigabitEthernet3/0/25] quit[Sysname] irf-port 3/1[Sysname-irf-port3/1] port group interface ten-gigabitethernet 3/0/25
